[00:08:49] <pcw_home> if its a high res encoder and a hardware encoder counter you cannot
[00:08:51] <pcw_home> observe the index pulse directly with any reliability
[00:10:25] <pcw_home> ( the pulse is too short to so very likely to be missed at linuxcnc's sampling interval )
[00:10:35] <pcw_home> -to
[00:23:14] <mac_wolf> pcw_home: thanks, it is a high count encoder and that is what I was thinking
[00:40:22] <mac_wolf> pcw_home:what if the encoder counter is the mesa 7i77?
[02:07:34] <Deejay> moin
[02:28:50] <mac_wolf> Hi Deejay
[02:45:14] <Deejay> hi mac_wolf
[02:58:33] <Jymmm> Deejay: Hey, do you actually CNC, or just say hi/bye daily =)
[02:59:30] <Deejay> hey Jymmm ;)
[02:59:45] <Jymmm> Deejay: just seems you are too busy all the time
[02:59:57] <Deejay> i have built my own little CNC for hobby purposes, yes, but i don't use it every day
[03:00:28] <Jymmm> Deejay: I didn't mean daily, just if you ever have any time yo use it =)
[03:00:50] <Deejay> hehe, yeah
[03:00:58] <Jymmm> ok cool =)
[03:06:32] <mac_wolf> aj
[03:07:06] <MacGalempsy> There were too many wolfs after the joke ended
[03:12:01] <Jymmm> Too many sheep in wolfs clothing
[03:40:39] <XXWolf> MacGalempsy: aw
[03:40:49] <XXWolf> you left Our flock
[03:41:14] <XXWolf> heh
[03:49:38] <MacGalempsy> XXWolf: I hope its not like a gang, only one way out...
[03:49:51] <XXWolf> oh theres LOTS way out
[03:50:04] <XXWolf> like being shot at, pushed off bridge.. so on...
[03:57:10] <anomynous> if you dont stop playing a gansta i will tell your mom.
[03:57:31] <XXWolf> good luck shes on boat no internet
[04:04:09] <Jymmm> sar phone ftw
[04:04:15] <Jymmm> sat*
[04:04:38] <XXWolf> money. she dont have. lol
[04:05:00] <XXWolf> name reads like "limpnoodle" lol https://www.kickstarter.com/projects/powerpractical/luminoodle-versatile-usb-lighting-solution?ref=HappeningNewsletterSep1815
[04:05:04] <Jymmm> Ia her name Maryann by chance?
[04:05:25] <XXWolf> no
[04:05:33] <Jymmm> Ginger?
[04:05:51] <XXWolf> dont remember her orginial hair color
[04:06:08] <Jymmm> Not hair, name?
[04:06:29] <XXWolf> no, nor any of common names :P
[04:06:47] <Jymmm> XXWolf: https://www.youtube.com/watch?v=cfR7qxtgCgY
[04:07:02] <XXWolf> ah lol
[04:07:14] <Jymmm> =)
[04:07:14] <XXWolf> I remember that sow
[04:07:29] <XXWolf> that captain failed
[04:07:46] <XXWolf> and skipper? resuce would be faster if they ate that skipper
[04:08:00] <Jymmm> haha
[04:08:54] <XXWolf> did you know they went to space?
[04:09:01] <Jymmm> $115 for a double throw switch =(
[04:40:56] <XXWolf> https://www.youtube.com/watch?v=JzR6FV-sdH4
[04:40:58] <XXWolf> interesting
[05:46:45] <MacGalempsy> well, another productive evening. I got the door-log pinned out, along with indicator lights for door open and door locked,
[05:47:26] <MacGalempsy> cant wait until my work space is as clean as NYC CNC
[05:48:00] <XXWolf> well messy ones better than none
[05:48:05] <XXWolf> mines in second living room
[05:48:07] <XXWolf> shortterm
[05:48:21] <XXWolf> I can run as long as I dont cut anything. very useful, that.
[05:48:29] <MacGalempsy> at least it is climate controlled :)
[05:48:45] <MacGalempsy> my garage is hot as hell in the summer and cold as a witches tit in the winter
[05:51:20] <enleth> MacGalempsy: be careful what you wish. My workshop is in a building with central heating, but there are no passive radiators. Instead, a single radiator with a huge centrifugal fan is installed. It is loud as fuck and makes a mess of any lighweight loose items left in front of the exhaust.
[05:52:17] <enleth> So people turn it on as required, go eat something, return 30 minutes later to turn it off and resume work.
[05:52:23] <XXWolf> one of stuff I plan to do first with cnc (once it passes calbrations) is to make enclosure for some parts
[05:52:40] <MacGalempsy> my old office was in my spare bedroom
[05:53:00] <MacGalempsy> had a bunch of cabinets, really a great layout. now it is a rental...
[06:00:29] <MattyMatt> yay. cheap magbase is wobbly. fun lapping time
[06:00:54] <XXWolf> heh
[06:01:09] <XXWolf> oky guess its time to end wolf thing
[06:02:04] <MattyMatt> http://www.ebay.co.uk/itm/like/DTI-stand-with-magnetic-base-NEW-Dti-stand-for-dial-gauges-strong-magnet-HT/201410507843 nice arm tho. I've envied real nogas
[06:03:36] <XXCoder> I do want full size verson, I has cheap small one that works pretty well.
[06:05:07] <MattyMatt> but the base is a disaster. the vgroove was ground first obviously, and sloping opposite diagonals, and then the base was ground and the lands started getting wider and someone saw that and paniced and tried to grind it opposite then gave up
[06:05:49] <MattyMatt> I'll ignore the wonky vgroove and just grind the base flat
[06:06:31] <MattyMatt> grind file. it ain't tool steel
[06:09:47] <XXCoder> interesting
[06:20:39] <MattyMatt> filing is easier with the magnet turned on :) no roundover
[06:20:49] <XXCoder> nice
[06:33:19] * Loetmichel just got a letter from the IKH( german agency for certifying jobs/apprentices)... "we search for new certification examiners, would you care about that?" ... ME of all peope... wo made it barely thru his own certification... i think they just noticed that they have not eough examiners for next year and have written this letter to ALL who are listed as trainers with them... :-)
[06:35:41] <XXCoder> if pay is awesome why not lol
[06:36:16] <XXCoder> http://www.homemadetools.net/ interesting
[06:36:52] <Loetmichel> XXCoder: its voluntary
[06:37:18] <Loetmichel> and i dont know shit about the job i would examine, besides having teached 2 apprentices in it now
[06:39:35] <XXCoder> sometimes you bullshit interview then learn just enough to not get fired
[06:39:40] <XXCoder> then actually get good on job
[06:59:47] <XXCoder> hm
[06:59:56] <XXCoder> wonder if this can be adopted to raspberry pi
[06:59:58] <XXCoder> http://www.circuitdb.com/?p=120
[07:03:22] <MattyMatt> Loetmichel. think of them as free slaves in your workshop
[07:03:46] <MattyMatt> if they survive all winter, they get a certificate :)
[07:05:38] <MattyMatt> sweeping floor A+ making coffee B- tuning repraps B+
[07:06:14] <MattyMatt> coffee wasn't quick enough and the overhangs are still drooping
[07:08:37] <MattyMatt> surely the teacher is the examiner, for an apprecntice?
[07:08:39] <XXCoder> MattyMatt: grade based on how many fingers left by end
[07:08:45] <XXCoder> 10 finger = a+
[07:08:58] <MattyMatt> 11 finger, summa cum laude
[07:09:08] <XXCoder> lol
[07:12:47] <MattyMatt> I need this little one for indicating because the big one's always behind my tablesaw fence
[07:13:03] <XXCoder> I'm not too sure how to use mine
[07:13:12] <XXCoder> because table is aluminium :('
[07:13:43] <MattyMatt> put a sheet of steel over it?
[07:14:08] <MattyMatt> just a few partial T slots maybe, the ones that you use
[07:14:43] <MacGalempsy> is there a method to test a hall sensor to determin the voltage required?
[07:16:13] <XXCoder> MacGalempsy: maybe
[07:16:21] <XXCoder> er MattyMatt
[07:17:25] <MattyMatt> I'cve noticed people use mats either side of their milling vice to keep most of the crap out the tslots
[07:17:39] <Loetmichel> MattyMatt:in germany there is an official exam by a state agency
[07:17:48] <Loetmichel> and NOT ny the trainer
[07:17:53] <Loetmichel> by
[07:18:07] <Loetmichel> usually the examiners are trainers for the job elsewhere tho
[07:18:08] <MattyMatt> so you get all the bribes? ka-ching
[07:18:19] <Loetmichel> and that job is voluntary
[07:18:19] <MacGalempsy> the problem is the sensors are hard to get to, i am thinking either 5 or 24v
[07:18:25] <Loetmichel> that examiner job
[07:18:38] <MacGalempsy> if the voltage is too high, do they get somked?
[07:18:58] <XXCoder> smoked no
[07:19:02] <XXCoder> release magic smoke yes
[07:19:09] <XXCoder> kidding dunno if it would or not
[07:19:25] <ikcalB> hey guys. 2 questions for you, if you mind sharing your experiences
[07:19:47] <MattyMatt> MacGalempsy, do you have a variable psu and a scope?
[07:19:59] <MacGalempsy> nope
[07:20:16] <MacGalempsy> i need to get a variable psu, or just get a pot
[07:20:24] <ikcalB> 1. where do you buy your tools (im in europe) and what are the most common shank diameters? usind a kress spindle (which collet sizes are good 2 buy)
[07:20:53] <MattyMatt> for very low power yeah a pot will do
[07:21:12] <MacGalempsy> these are the last two sensors
[07:21:49] <MattyMatt> or just try a few voltages. start low obviously, and see how clean the signal is (somehow, maybe a meter will do for watching square waves)
[07:22:17] <ikcalB> 2. which material for slot nuts to use - i don't see stability advantage of iron over aluminum
[07:22:42] <Loetmichel> aluminium threads are prone to wear out fast
[07:23:14] <Loetmichel> so with aluminium nuts you'll have to use some kind of helicoil or similar to get long lasting nuts
[07:23:26] <Loetmichel> other than that i see no problem with aluminium
[07:24:16] <ikcalB> loetmichel: tnx for ur input, agreed. using iron then
[07:24:31] <MattyMatt> iron or steel?
[07:25:14] <ikcalB> mattymatt: steel.
[07:25:25] <MattyMatt> cast iron threads aren't any stronger than alu, afaics
[07:26:07] <MattyMatt> I think I've stripped the one in the top of this magbase already
[07:26:15] <Loetmichel> MattyMatt: IIRC its niot the fact that aluminium is weaker, its the fact that is "smears" that ruins the threads fast
[07:26:33] <ikcalB> mattymatt: non-native speaker
[07:26:59] <Loetmichel> ikcalB: for the tools: i use www.sorotec.de
[07:27:11] <Loetmichel> for my mill bits
[07:27:37] <MattyMatt> I'm in UK, and 1/4" and 1/2" are still more common than metric
[07:28:21] <Loetmichel> most of my small bits are the "pcb mill tungsten carbide" kind... which has an 1/8" shank.
[07:28:43] <Loetmichel> but 3mm, 4mm, 6mm and 8mm shanks are also common in germany
[07:30:25] <Loetmichel> MattyMatt: afaics= "as far as i can see"?
[07:30:31] <MattyMatt> yes
[07:31:47] <Loetmichel> btw: anyone knows a german supplier of small amounts of helicoil and tools?
[07:32:09] <Loetmichel> my spindle holder at the company mill is only fixed by 2 of the 4 M8 bolts
[07:32:32] <Loetmichel> the other two are just "soved in and fixed with CA glue" ;)
[07:32:40] <Loetmichel> shoved
[07:33:10] <Loetmichel> ... the threaded holes were in extrided aluminium
[07:33:22] <Loetmichel> VERY ductile stuff :-(
[07:33:25] <MattyMatt> http://www.ebay.de/sch/i.html?_nkw=helicoil
[07:34:23] <MattyMatt> wow real ones. ebay.co.uk is full of the red handled ones
[07:34:41] <Loetmichel> *COUGH*
[07:34:45] <ikcalB> loetmichel: sorotec looks reasonably well for medium (high) quality tools. the machine i use has weak mechanics (gift) - still have to see what its capable of
[07:34:48] <Loetmichel> 40 eurs for two repairs...
[07:35:08] <ikcalB> have you used china-mills from ebay too & of what quality are those?
[07:35:32] <Loetmichel> ikcalB: my home mill is selfmade
[07:35:39] <Loetmichel> my company mill is a chinese CNC 6040
[07:35:48] <Loetmichel> so both are not that sturdy
[07:35:59] <Loetmichel> but good tools go a long way
[07:36:25] <MattyMatt> if I open the window and throw really hard, so o the bad ones
[07:36:35] <Loetmichel> https://www.youtube.com/watch?v=BWTTP0RomA0
[07:36:56] <Loetmichel> https://www.youtube.com/watch?v=AkKHPsJtZlc
[07:37:04] <Loetmichel> https://www.youtube.com/watch?v=9u_ChO1AKYY
[07:37:05] <Loetmichel> :-)
[07:37:10] <ikcalB> loetmichel: i know, am familiar with cnc itself. for pcb routing i need to use very small diameter tools - rather make the first tries with cheap ones
[07:37:37] <Loetmichel> you mean like that?
[07:37:45] <Loetmichel> https://www.youtube.com/watch?v=jMXxjT4nNxg
[07:38:06] <MattyMatt> start with a vbit, if you want to get experience without breaking tools
[07:38:13] <Loetmichel> http://www.sorotec.de/shop/Cutting-Tools/Routing-Tools/V-Router-Bit/V-Router-Bit-30-.html <- ideal tool for that job
[07:38:28] <ikcalB> exactely ^^
[07:38:46] <MattyMatt> I get through a lot of 0.8mm cheapos, and not because they are cheap, but because I'm clumsy
[07:39:49] <XXCoder> wonder wheres good source of cheap tools
[07:40:01] <Loetmichel> MattyMatt: i have used a bunch of 0.4mm TC ones...
[07:40:04] <XXCoder> aliexpress and amazon do have em but its nearly impossible to search for sizes
[07:40:13] <Loetmichel> dont cough to loud or they break ;)
[07:40:47] <ikcalB> loetmichel: so you say those cheap china mills are real crap? tnx.
[07:40:48] <MattyMatt> http://www.ebay.de/itm/Hartmetallfraser-Set-Platinenfraser-Schaft-3-175mm-PCB-Corn-End-Mill-Carbide-/151724702220
[07:41:22] <MattyMatt> they are crap, but they are TC and they break just as easily. I'd rather learn on $2 a mistake
[07:41:33] <Loetmichel> ikcalB: i dont say the machines are crap
[07:41:44] <Loetmichel> just not as rigid as one whishes them to be
[07:41:45] <MattyMatt> the suspiciously cheap ones on ebay are all resharpened ones
[07:41:55] <Loetmichel> so you have to work around that
[07:41:58] <MattyMatt> but hey, if they're sharp
[07:42:10] <Loetmichel> or did you mean the tools?
[07:42:44] <Loetmichel> MattyMatt: i often use selfground cutters on my machine
[07:43:05] <Loetmichel> ...haviong about 1kg of broken 1/8" shanks in the box ;)
[07:43:29] <Loetmichel> ... its surprisingly easy after you ground about 20-30 of them to get them cutting right
[07:43:40] <ikcalB> loetmichel: not the milling machines - the milling cutters.
[07:43:59] <MattyMatt> I tried to sharpen the stub of the TC into a scriber point on my grey stone yesterday, it won't touch it
[07:43:59] <Loetmichel> the cutters are basically crap if resharpened
[07:44:12] <Loetmichel> and the chinese ones tend be have a way to high runout
[07:44:35] <Loetmichel> i would stick to german suppliers or at least european ones that are known to have a good QC
[07:44:57] <Loetmichel> MattyMatt: i use diamont cutting discs for that
[07:44:58] <MattyMatt> or make a cnc toolgrinder with a microscope
[07:45:22] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=8961
[07:45:23] <XXCoder> Loetmichel: depends on what precision youre looking for. for example for me and my wood stuff .001" is bit overprecise
[07:45:26] <Loetmichel> ... freehand
[07:45:27] <ikcalB> loetmichel: ok, tnx! btw: are u using those china X kW spindles on the pcb-milling video?
[07:45:40] <Loetmichel> yes
[07:45:48] <Loetmichel> the 800W watercooled kind
[07:46:10] <ikcalB> is it rellay true, that the runout is <5µ? how sturdy / usable is it?
[07:46:26] <Loetmichel> MattyMatt: with a bit of experience i get those engraving cutteers down to 0,01mm precision
[07:46:38] <Loetmichel> its easy if you have done a few 10 ;)
[07:46:51] <Loetmichel> ikcalB: depends
[07:47:08] <Loetmichel> my two spinles have less than 0,01mm runout
[07:47:12] <Loetmichel> cant measure any
[07:47:25] <Loetmichel> but i have read about a few that are way worse
[07:47:30] <MattyMatt> nice. I can do drill bits now by sweeping across a standard dremel disc, without breaking it
[07:47:30] <Loetmichel> up to 0,2mm runout
[07:48:07] <XXCoder> Loetmichel: though I wonder a bit. is it possible to just buy cheapass tools and regrind for better runout at shop (assuming has grinder)
[07:48:25] <Loetmichel> not the usual tools
[07:48:36] <ikcalB> ok. given that the runout is as advertised, have you done enough "hard" milling (maybe metal) to say if the bearings are sturdy enough?
[07:48:47] <Loetmichel> you can only make the "halved cutter" kind to reasonable accuracy at home freehand
[07:49:09] <Loetmichel> not the ones with spiral flutes and 2 or more cutting edges
[07:49:52] <Loetmichel> ikcalB: the spindle at the company is now starting to "sing" in the bearings after 2 years of use in aluminium mostly
[07:50:04] <Loetmichel> which is an ok lifetime of the bearings i think
[07:50:32] <Loetmichel> tghe spindle at home wich is used much less is still good
[07:51:49] <MattyMatt> how big is the 800W vfd? they all look the same in photos but in videos the 2.2kW ones are enormous
[07:52:04] <Loetmichel> depends
[07:52:18] <Loetmichel> the one i have got with the home spindle is small
[07:52:31] <Loetmichel> the one at the company came with an 1,5kw vfd
[07:53:00] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14148&g2_imageViewsIndex=1 <- comany
[07:53:35] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12569&g2_imageViewsIndex=1 <- home
[07:54:22] <MattyMatt> I can't see the vfd in either of those pics :) they must be small
[07:54:45] <Loetmichel> the dark grey boxes with the red 7segment displays
[07:54:45] <MattyMatt> oh yeah there it is on the wall at home
[07:55:09] <MattyMatt> duh and behind the machine
[07:55:16] <Loetmichel> :-)
[07:55:22] * MattyMatt expecting cream colour
[07:56:07] <MattyMatt> this must be coffee time
[07:56:35] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12506 <- home set like it was delivered
[07:59:49] <Loetmichel> https://www.youtube.com/watch?v=dEQZ_TY5q8o <- the one of the company in action
[08:00:40] <Loetmichel> https://www.youtube.com/watch?v=a9Ov69t0uwo <- the one at home
[08:03:19] <ikcalB> loetmichel: 2y sounds reasonable enough. do you have any approx. runtimes in contact?
[08:04:10] <Loetmichel> ikcalB: about 2 hours a workday approx.
[08:04:16] <Loetmichel> for the company one
[08:04:25] <ikcalB> those spindles are really attracting me, for my own redesign
[08:04:30] <ikcalB> perfekt, tnx
[08:04:53] <Loetmichel> and it still works without any measurable rattle. just starts getting noisy
[08:05:33] <ikcalB> for 2y thats about 1000hrs - for ... 300€? 30c per hour. pretty acceptable
[08:06:39] <Loetmichel> the bearings are pretty easy to replace tho
[08:07:05] <ikcalB> do those spindles have skf bearings? (they currently are advertised as such)
[08:07:08] <Loetmichel> and cheap, being normal 6201/6201 iirc
[08:07:16] <Loetmichel> they have chinese bearings
[08:07:33] <Loetmichel> at least the one i dismantled
[08:07:49] <Loetmichel> "german bearings" turns otu to be a chinese company
[08:08:36] <Loetmichel> 6201/6202
[08:09:00] <ikcalB> well, i wouldn't doubt that, if you claim. still, i though skf had high quality bearings? (are used in DMG spindles, and even older HERMLE ones. cant tell about recent ones)
[08:09:05] <MattyMatt> it's their way of controlling the natives. shiny beads and defective weapons
[08:09:25] <Loetmichel> they are not that bad in quality
[08:09:48] <Loetmichel> just not the skf ones
[08:09:50] <Loetmichel> or FAG
[08:10:01] <ikcalB> sounds really good
[08:10:48] <MattyMatt> with cheap chinese bearings, you could routinely replace them every year and probably be a winner
[08:11:18] <Loetmichel> i mean: how good can a spindle be which uses ball bearings instead of spindle ones?
[08:11:28] <MattyMatt> if you had a press, and jigs to make it an easy regular job
[08:11:40] <Loetmichel> you dont need a press
[08:11:50] <Loetmichel> just a bit of muscle and a fork
[08:11:58] <Loetmichel> the bearings are not heat-shrinked in place
[08:12:14] <Loetmichel> they slip on and off pretty easy
[08:13:20] <Loetmichel> i recommend some loctite "welle/nabe" to mount them tho
[08:13:39] <Loetmichel> some of the ones i had to replace tend to be a bit too loose ;)
[08:13:43] <ikcalB> loetmichel: what bits do you use for drilling <= 1mm in FR4? (THT holes)
[08:13:57] <Loetmichel> tungsten carbide from sorotec
[08:13:57] <MattyMatt> emergency extra bearing for when the balls seize up
[08:15:19] <Loetmichel> ikcalB: http://www.cyrom.org/palbum/main.php?g2_itemId=11933&g2_imageViewsIndex=1
[08:16:30] <Loetmichel> i have them down to 0,3mm
[08:16:41] <Loetmichel> and the mill bits down to 0,4mm ;)
[08:17:04] <ikcalB> they look good - you said they last long too? and that for about the same price as the cheapos on ebay. with lot less hassle and waiting time? sound to good to be true
[08:17:30] <Loetmichel> they do last long
[08:17:49] <Loetmichel> i never got one of them dull in PCB... they always break beforehand by ishap
[08:17:52] <Loetmichel> mishap
[08:18:24] <Loetmichel> i think i had one of the 0,6mm ones do 14 europe card sized PCBs
[08:18:52] <Loetmichel> before breking it off
[08:20:11] <Loetmichel> especially the 0,3 and 0,4mm ones can break off to a heavy sneeze tho
[08:20:16] <Loetmichel> so be careful ;)
[08:21:53] <MattyMatt> those spindles only do about 10k rpm at 400hz don't they?
[08:22:03] <Loetmichel> 24krpm
[08:22:06] <Loetmichel> at 400hz
[08:22:16] <MattyMatt> ah cool. plenty fast enough for pcb
[08:22:34] <Loetmichel> i would like the new 600W ones that can do 60k tho
[08:22:40] <Loetmichel> for pcb thats even better
[08:23:04] <Loetmichel> especially for drilling 0,3mm holes ;)
[08:25:01] <MattyMatt> I need something heavy and slow next. something made like my lathe headstock would do me. 2 speeds is plenty
[08:25:58] <MattyMatt> http://imgur.com/bq9ok simple and cheap. I have the bearings
[08:26:10] <MattyMatt> and I can make the pulleys
[08:26:52] <MattyMatt> or gears
[08:29:45] <Contract_Pilot> Ahhhh gun show all weekend then i get to play. http://www.stevenrhine.com/wp-content/uploads/2015/09/Arizona-G0704-CNC-Brackets-225x300.jpg
[08:30:33] <MattyMatt> that looks like an X axis conversion?
[08:33:35] <MattyMatt> http://www.ebay.co.uk/itm/Milling-Head-Square-Tramming-Gauge-Edge-Technology-1-8-Shank-/231205535219 1/8" shank? tram that dremel
[08:34:16] <zeewolf> bah why do i wake up early on a sat
[08:34:28] <MattyMatt> I guess that would actually be handy if you use 1/8" tooling in a real spindle
[08:35:38] <zeeshan> cute little shank
[08:37:50] <MattyMatt> i was thinking of making a mini coaxial indicator yesterday, one that you clip on a button back indicator too
[08:39:08] <MattyMatt> that'd be fine work tho, making even a lever system without slop
[08:41:11] <Loetmichel> i used a permanet marker, some 3mm copper wire bend to a "z" and some duct tape to tram my two spindles :-)
[08:41:47] <MattyMatt> good plan :) I'll use coathanger it's stiffer
[08:42:00] <MattyMatt> (and 1/8" so I won't need to change the collet)
[08:42:24] <Loetmichel> ER11 1/8" collets also grip 3mm
[08:42:35] <Loetmichel> and the copper wire was laying around
[08:42:44] <MattyMatt> ah sorry didn't read 3mm
[08:42:57] <MattyMatt> or read it as 3mm²
[08:43:48] <Loetmichel> i once used a saw blade as a cutting mill... stood behind the side walls of the gantry when using that...
[08:44:11] <MattyMatt> you could use the same trick as a coaxial indicator too, inside a large hole
[08:44:14] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=5474
[08:44:20] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=5471
[08:44:25] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=5468
[08:44:35] <Loetmichel> at 24krp thats quite scary ;)
[08:44:53] <XXCoder> Loetmichel: I saw those special bit that looks like saw blade
[08:44:55] <XXCoder> but not
[08:45:39] <Loetmichel> XXCoder: i mande that holder myself of a m10 screw
[08:45:41] <XXCoder> it was kinda scary because I was running hurco vm10 that time. if pause was pressed it would go stright up, ripping part off.
[08:45:41] <Loetmichel> and nut
[08:45:53] <XXCoder> with lock of some sort I hope.
[08:45:56] <Loetmichel> ... it WAS an 80mm circular saw blade i can assure you
[08:46:23] <Loetmichel> look at the pics
[08:46:25] <Loetmichel> no lock
[08:46:28] <Loetmichel> just the nut
[08:46:52] <XXCoder> you was right to stand behind walls lol
[08:47:12] <XXCoder> "I come in peace" disk thingy could have happened lol
[08:47:59] <Loetmichel> especially when you contemplate the 0,4mm taper at the end of the screw thats holding the blade in place ;)
[08:48:32] <Loetmichel> i was determined to have it cutting flush on the underside ;)
[08:48:38] <XXCoder> crazy
[08:48:41] <MattyMatt> I should get a smaller thinner blade for my tablesaw. 400mm diameter and 4mm thick, is too much for most things
[08:49:02] * XXCoder is surpised someone knows about "I come in peace". What a strange movie.
[08:49:31] <Loetmichel> a lot of cnc people are also SF fans ;)
[08:50:04] <XXCoder> you know about that movie that has tank that has tri wheel arrgangement?
[08:50:14] <XXCoder> some post-end of world movie
[08:52:14] <XXCoder> ahh Damnation Alley
[08:54:03] <XXCoder> Loetmichel: http://ia.media-imdb.com/images/M/MV5BMjAxNDEwMjg3OV5BMl5BanBnXkFtZTYwMjg4MjU2._V1_SX640_SY720_.jpg
[08:54:27] <XXCoder> I made the wheel setup in lego., it wasn't easy
[08:54:34] <XXCoder> been long while ago
[08:56:09] <ikcalB> XXXCoder: tri wheel arrangement? how cool would that look...
[08:56:17] <XXCoder> ikcalB: very cool.
[08:56:28] <XXCoder> all wheels is constantlyrotating when running
[08:56:35] <XXCoder> but if it jams whole thing rotates
[08:56:42] <XXCoder> https://www.youtube.com/watch?v=Q1ssLae4ETc
[08:56:49] <ikcalB> will have that movie on my list
[08:56:57] <anomynous> what is generic name for axle and hole tolerance classes?
[08:57:36] <XXCoder> ikcalB: someone found the landmasrer parked at some apt space
[08:57:43] <XXCoder> so its still around in least
[08:58:43] <Tom_itx> anomynous, https://www.engineersedge.com/general_tolerances.htm
[09:00:07] <zeeshan> tom hi
[09:00:25] <Tom_itx> zee wolf only comes out at night?
[09:00:27] <ikcalB> XXXCoder: sry, what do you mean by apt space?
[09:00:57] <XXCoder> ikcalB: just read update, it is in storage now
[09:01:01] <zeeshan> haha
[09:01:02] <XXCoder> since someone damaged it a little
[09:01:19] <Tom_itx> zeeshan, been learning SW and CATIA both at once this week
[09:01:27] <zeeshan> nice
[09:01:28] <ikcalB> k
[09:01:31] <zeeshan> at school?
[09:01:49] <Tom_itx> my kid is taking the catia class and i'm doing the drawings with him in SW helping him with CATIA
[09:02:15] <Tom_itx> good to learn the differences
[09:03:14] <Tom_itx> did you figure out your subroutine thing with the G54 x offset increasing?
[09:03:52] <zeeshan> working on it now
[09:03:53] <Tom_itx> one bad thing about that is if you had to stop and rerun one
[09:04:14] <zeeshan> im trying to do it all within mastercam
[09:04:18] <zeeshan> it should be able to handle it
[09:04:23] <zeeshan> rather than having to do it manually
[09:04:30] <Tom_itx> repeat all the code or do a sub?
[09:04:36] <zeeshan> both
[09:04:45] <Tom_itx> the code version will be huge
[09:04:49] <Tom_itx> but it should work fine
[09:05:13] <Tom_itx> on a normal machine we would just DNC something like that
[09:05:39] <zeeshan> dnc ?
[09:05:51] <Tom_itx> spoon feed it from the pc
[09:06:06] <Tom_itx> via serial link etc
[09:06:09] <zeeshan> ah
[09:06:34] <Tom_itx> fills the machine buffer then waits
[09:10:09] <zeeshan> lemme show you whats up
[09:10:29] <zeeshan> http://i.imgur.com/g3fL4eG.png
[09:10:45] <zeeshan> so the very middle part w/ the coordinate system
[09:10:55] <zeeshan> thats my op1 coordinate system where x points to the right
[09:11:04] <zeeshan> all the op1 repititions are on the right
[09:11:20] <zeeshan> then i transform the coordinate system by 180 degrees about the Y axis
[09:11:39] <zeeshan> so the x is pointing to the left
[09:11:45] <zeeshan> and machine all the undersides
[09:11:49] <zeeshan> (op2)
[09:12:36] <Tom_itx> you should make that G55
[09:12:52] <Tom_itx> change fixture offsets with any OP change
[09:13:16] <zeeshan> hm
[09:16:18] <zeeshan> whats the benefit of doing that?
[09:16:21] <zeeshan> vs how i have it
[09:16:52] <Tom_itx> if you need to rerun an op you don't have to go clear thru the first half code for one
[09:17:18] <Tom_itx> and in a regular shop it defines the operations as well
[09:17:53] <Tom_itx> generally run as a separate code file
[09:18:11] <Tom_itx> some ops are monkeys and that helps the confusion
[09:18:30] <zeeshan> im looking at the output of the nc
[09:18:37] <zeeshan> its repeating the code
[09:18:41] <zeeshan> with no subroutine
[09:18:43] <zeeshan> will try subroutine option now
[09:21:43] <zeeshan> it's not making subroutines :{
[09:22:10] <Tom_itx> i never tried that with cad
[09:22:19] <Tom_itx> no real reason to
[09:22:29] <zeeshan> honestly
[09:22:34] <zeeshan> thats how all the manufacutirng engineers do it
[09:22:35] <zeeshan> all in cad
[09:22:40] <zeeshan> leaves very little room for error
[09:22:49] <zeeshan> thats why im trying to get used to it
[09:22:58] <zeeshan> these jobs i do really are a learning experience for me
[09:23:03] <zeeshan> not in it for the money
[09:30:10] <Tom_itx> optimize the ops between parts too. run all the first tool first on G54 etc
[09:30:29] <Tom_itx> looks like you did that
[09:32:02] <Tom_itx> how do you extrude a cone in SW?
[09:32:15] <zeeshan> dont think of it as an extrude
[09:32:30] <zeeshan> revolved would be easiest
[09:32:35] <zeeshan> draw a triangle
[09:32:38] <zeeshan> and revolve about the center line
[09:32:44] <Tom_itx> k
[09:33:27] <zeeshan> yayyyyyyyyyyy
[09:33:30] <zeeshan> it's outputting sub routines!!!
[09:33:56] <Tom_itx> test will be when you run it
[09:34:42] <zeeshan> yes
[09:34:46] <zeeshan> well if it displays right on axis
[09:34:53] <zeeshan> itll be a a little bit of stress relioef
[09:35:22] <zeeshan> its kinda interesting how this is doing it
[09:35:40] <Tom_itx> i would still treat the left side as G55
[09:38:51] <zeeshan> damn it
[09:38:53] <zeeshan> its outputting m98
[09:39:00] <zeeshan> which linuxcnc doesnt recognize
[09:39:10] <Tom_itx> fix it
[09:40:14] <Tom_itx> O word instead
[09:40:56] <zeeshan> okay first thing
[09:40:59] <zeeshan> its outputting G52
[09:41:11] <zeeshan> like it's doing g52 x2.625 , then m98 p0001
[09:41:22] <zeeshan> then it goes g52 x-5.25 then m98 p0001
[09:41:23] <zeeshan> etc
[09:41:47] <zeeshan> so it seems like g52 is basically g10 l20 in linuxcnc
[09:42:08] <zeeshan> er
[09:42:10] <zeeshan> g10 l2
[09:45:01] <zeeshan> okay all m98s
[09:45:03] <zeeshan> have to be replaced with
[09:45:14] <zeeshan> O##### call
[09:45:22] <Tom_itx> uh huh
[09:45:22] <zeeshan> and all subroutines must have
[09:45:25] <Tom_itx> ^^
[09:45:26] <zeeshan> o### sub
[09:45:28] <zeeshan> blah blah blah
[09:45:33] <zeeshan> 0### endsub
[09:45:38] <Tom_itx> yup
[09:45:39] <zeeshan> okay its not too hard tm odify the post processor to do this
[09:45:45] <zeeshan> i like the subourtine output
[09:45:50] <zeeshan> cause i can easily modify the code down at the machine
[09:45:57] <zeeshan> if i need to rerun some code
[09:46:02] <Tom_itx> run one part but add the sub manually
[09:46:19] <zeeshan> i already know the code for 1 part works
[09:46:23] <zeeshan> i wanna do it all in cam
[09:46:28] <zeeshan> cause i have an assembly in cad
[09:46:30] <Tom_itx> mod the post then
[09:46:32] <zeeshan> and i can see all the tool paths
[09:46:34] <zeeshan> yes
[09:46:42] <Tom_itx> keep your original
[09:46:45] <Tom_itx> for normal parts
[09:53:16] <jvm_> hi. can linuxcnc simulate workpiece cutting / tool collisions and influence on the workpiece?
[09:54:21] <zeeshan> no
[09:54:34] <zeeshan> it backplots the tool path
[09:54:35] <zeeshan> as far as i know
[09:55:05] <jvm_> did anyone start a project like this?
[09:55:15] <jvm_> can i help? ;)
[09:55:44] <archivist> jvm_, there was a simulated cut once upon a time
[09:55:58] <zeeshan> jvm_: i dont mean to put the idea down
[09:56:05] <zeeshan> but what youre describing is something cam handles?
[09:56:07] <zeeshan> you'
[09:56:10] <archivist> it had few tools and some math bugs
[09:56:15] <zeeshan> you're basically trying to integrate cam w/ linuxcnc?
[09:56:35] <archivist> simulated cut is not cam
[09:56:40] <zeeshan> so youre saying
[09:56:43] <zeeshan> it'll pick up things like
[09:56:47] <zeeshan> rapiding through a work piece
[09:56:59] <PetefromTn_> you would have to model your materials etc in linuxCNC somehow
[09:57:15] <PetefromTn_> as well as vises,jaws, fixtures etc.
[09:57:17] <jvm_> i would like to have a 3d simulation of what the g-code would do on "an idealized" cnc machine.
[09:57:25] <zeeshan> well just even a collision w/ a part would be useful
[09:57:28] <archivist> see openscam
[09:57:29] <zeeshan> if you could import your cad data
[09:57:31] <jvm_> with a simple workpiece.
[09:57:36] <zeeshan> so it generates a boundary
[09:57:39] <zeeshan> could help
[09:57:44] <archivist> jvm_, see openscam
[09:57:51] <PetefromTn_> many CAM Programs already do this for you
[09:58:07] <SpeedEvil> More integration in some way might be interesting.
[09:58:11] <jvm_> PetefromTn_, open source ones?
[09:58:12] <SpeedEvil> But it has its own costs.
[09:58:17] <jvm_> Please give me pointers :)
[09:58:20] <archivist> none do my 5 axis suff
[09:58:27] <jvm_> I'll look into openscam, thank you archivist.
[09:58:37] <zeeshan> archivist: solidcam
[09:58:38] <PetefromTn_> I am not aware of any open source cam programs with that capability no
[09:58:42] <zeeshan> mastercam both handle 5 axis
[09:58:43] <zeeshan> ez
[09:58:44] <zeeshan> peezee!
[09:58:47] <Tom_itx> years ago i used NSee for part verification
[09:58:47] <zeeshan> like my name!
[09:59:11] <archivist> PetefromTn_, openscam is one
[09:59:14] <Tom_itx> cam programs will generally use the geometry, not the gcode output to verify
[09:59:21] <Tom_itx> PetefromTn_ ^^
[09:59:29] <archivist> awallin was writing one too
[10:00:06] <PetefromTn_> archivist I said I am not aware of any I have no experience with openscam
[10:00:11] <archivist> http://www.anderswallin.net/category/cnc/
[10:02:16] <PetefromTn_> to be honest with you I would be very happy to have an open source CAM that had any real capabilities let alone part verification and crash avoidance features
[10:03:46] <archivist> there are a few but I hesitate to mention them because of "features"
[10:04:47] <archivist> crash avoidance would be something that should be done with vismach probably
[10:04:54] <jvm_> archivist, thank you, openscam looks very interesting :)
[10:05:04] <zeeshan> hsmworks
[10:05:05] <zeeshan> freeeeeeeeee
[10:05:23] <archivist> linux!
[10:05:26] <anomynous> what cam? fusion 360 has 4th and 5th axis coming soon i think
[10:05:33] <PetefromTn_> heh it's only free if you already own Solidworks
[10:05:56] <anomynous> and solidworks is only 4k€ if you dont
[10:05:57] <anomynous> ;D
[10:06:23] <Tom_itx> that's not so bad really
[10:06:33] <anomynous> compare that with fusion if you're a hobbyist
[10:06:35] <anomynous> it is free
[10:06:41] <archivist> unaffodium for most
[10:06:41] <Tom_itx> i gave 6 20+ yrs ago for one such cad cam
[10:07:20] <anomynous> also, mastercam is unbelivably expensive, if you are not getting a copy of some really old software used or pirate it
[10:07:28] <PetefromTn_> archivist I noticed that link you posted has some information on the CAM module for Freecad
[10:08:28] <archivist> even the gerber to gcode programs are cam
[10:08:49] <Tom_itx> gcpreview is free
[10:08:58] <Tom_itx> for gerber and it's darn good
[10:09:01] <anomynous> why not just run single block
[10:09:02] <anomynous> ;D
[10:09:17] <Tom_itx> try that on a surface program
[10:09:30] <archivist> define "single block"
[10:09:33] <anomynous> hire someone to press the button if your finger gets tired
[10:09:34] <anomynous> duh
[10:09:35] <anomynous> ;D
[10:09:52] <anomynous> or put m1 in critical sections
[10:10:21] <jvm_> http://www.cutviewer.com/ for 200$.
[10:11:23] <zeeshan> thats cheap
[10:11:27] <zeeshan> for sldwrks
[10:11:38] <zeeshan> or you can just take 1 course a year
[10:11:41] <zeeshan> and be considered a student :P
[10:12:00] <anomynous> cnccookbook software looked nice too. and you also have stack trace for macros... iirc ;D
[10:12:22] <anomynous> (a gcode editor)
[10:12:56] <PetefromTn_> jeez man by beard trimmer died....anyone got a recommendation on a new one LOL?
[10:13:05] <archivist> longer beard
[10:13:16] <jvm_> like
[10:13:18] <anomynous> gilette ;)
[10:13:19] <PetefromTn_> naah
[10:13:31] <PetefromTn_> I mean a cordless trimmer
[10:13:37] <anomynous> it is cordless
[10:13:51] <PetefromTn_> I know I know you're here all night
[10:13:58] <anomynous> sorry
[10:14:00] <anomynous> ;)
[10:15:23] <PetefromTn_> Oh well maybe all you guys don't grow hair or something ;)
[10:15:56] <archivist> my beard started in the early 1970's :)
[10:16:18] <PetefromTn_> jeez man your beard is older than I am hehe
[10:16:32] <archivist> grows till the fall out rate matches the growth rate
[10:17:00] <PetefromTn_> I have had one before.....could not stand the itching for more than a month or so
[10:17:41] <zeeshan> Tom_itx: is the program name case sensitive
[10:17:47] <zeeshan> like O1000 vs o1000
[10:18:31] <Tom_itx> i'm not sure but it may be
[10:18:56] <Tom_itx> http://linuxcnc.org/docs/2.7/html/gcode/o-code.html
[10:19:03] <Tom_itx> lower case 'o'
[10:19:38] <Tom_itx> years ago 'O' was used for text in the gcode
[10:19:43] <Tom_itx> linuxcnc doesn't like that
[10:19:59] <PetefromTn_> I need like the safe/diminutive version of a hedge trimmer ;)
[10:20:41] <Tom_itx> get a sheep shear
[10:20:54] <PetefromTn_> but I don't own a sheep
[10:21:16] <Jymmm> PetefromTn_: (Your OTHER gf)
[10:21:28] <PetefromTn_> LOL that reminds me of a comedians line
[10:21:49] <PetefromTn_> Your wife's a Bigfoot isn't she gus.....because you shaved her down and taught her to speak!
[10:21:57] <Jymmm> goony goo goo
[10:22:01] <PetefromTn_> YAYAYAYA
[10:22:08] <PetefromTn_> that is some funny stuff
[10:23:00] <Jymmm> Eddie Murphy Delirious https://www.youtube.com/watch?v=6p3QhnRTp1M
[10:29:28] <zeeshan> Tom_itx: halp
[10:29:50] <zeeshan> i got all the subourtines outputting right
[10:29:54] <zeeshan> but im confused on g52
[10:30:46] <zeeshan> actually g10 l2 is confusing me
[10:30:58] <zeeshan> say my g54 is considered x0,y0,z0
[10:31:16] <zeeshan> when i do g10 l2 x5, the g54 coordinate updates ?
[10:31:33] <zeeshan> to x5. y0. z0.?
[10:31:48] <Jymmm> zeeshan: I thought G6 would confuse you https://youtu.be/w4s6H4ku6ZY
[10:32:01] <zeeshan> i hate that song
[10:32:04] <zeeshan> :P
[10:32:53] <Jymmm> zeeshan: just a hater
[10:32:54] <zeeshan> nm got my answer
[10:33:01] <zeeshan> i need to do g10 l2 p1 x0 y0 z0
[10:33:02] <Tom_itx> i don't use G10 much
[10:33:07] <zeeshan> after im done all the offset shit
[10:33:10] <zeeshan> otherwise it wont return.
[10:35:08] <zeeshan> Jymmm: listen to a better song https://www.youtube.com/watch?v=gAeWAwdZf9I
[10:36:35] <Jymmm> zeeshan: good song
[10:36:42] <zeeshan> im addicted to it
[10:36:49] <zeeshan> i usually dont like the banjo
[10:36:54] <zeeshan> but i love it now
[10:39:58] <Jymmm> zeeshan: https://www.youtube.com/watch?v=MYSVMgRr6pw
[10:40:48] <zeeshan> that is a good song
[10:40:48] <zeeshan> :D
[10:41:45] <zeeshan> god i love mastercam
[10:41:54] <zeeshan> it optimized all the tool usage for me
[10:42:05] <zeeshan> so it'll do all 5 fixtures with tool 1 for example
[10:42:11] <zeeshan> and do another tool path with tool 2
[10:42:12] <zeeshan> smart
[10:42:37] <zeeshan> doing this by hand would SUCK
[10:42:44] <Tom_itx> most will do that
[10:42:57] <Tom_itx> even mine will as old as it is
[10:43:29] <zeeshan> not comparing it with others
[10:43:31] <Tom_itx> you can order them too
[10:43:33] <zeeshan> comparing it with manual
[10:43:56] <Jymmm> https://www.youtube.com/watch?v=vCZ1YteCv5M
[10:44:05] <zeeshan> i was just thinking the other day
[10:44:18] <zeeshan> autodesk's move to release all inventor versions for free to students
[10:44:25] <zeeshan> and hsmexpress was a smart move.
[10:44:39] <zeeshan> now a lot of schools and transitioning to it, cause they dont have to pay licensing fees
[10:44:48] <zeeshan> and it's forcing companies to swap
[10:45:15] <zeeshan> they did it at a critical time too where most of the work force is retirning
[10:45:36] <zeeshan> autodesk sales will go through the roof :P
[10:50:43] <Jymmm> What makes this a single pole breaker? http://www.ebay.com/itm/Zinsco-Circuit-Breaker-Thin-20-Amp-Tandem-single-Pole-used/191690864070 compared to a two pole http://www.ebay.com/itm/Zinsco-20amp-2-pole-circuit-breaker-/121737045420 They both "look" the same
[10:52:21] <zeeshan> Jymmm: they're both single pole breakers
[10:52:40] <zeeshan> just in the one with 2 levers
[10:52:46] <zeeshan> the pole is split into 2 circuits
[10:53:31] <zeeshan> my understanding of the term pole is
[10:53:39] <zeeshan> its the same as saying l1 l2 l3
[10:53:47] <zeeshan> its basically the # of wires coming from your utility pole
[10:53:57] <zeeshan> so even though its a single phase system l1 and l2
[10:54:03] <zeeshan> you still got 2 poles.
[10:54:06] <zeeshan> but you could have 3 phase
[10:54:12] <zeeshan> and those 2 poles are nothing to do with single phase
[10:54:38] <Jymmm> This is all signle phase
[10:54:41] <zeeshan> yes
[10:54:45] <zeeshan> im trying to explain the definition of pole
[10:54:49] <zeeshan> and telling you that person on ebay is wrong
[10:54:53] <zeeshan> in calling it 2 pole
[10:54:57] <zeeshan> and misleading people
[10:56:13] <Jymmm> The "tandem" bar, can I add if missing and are they easy to come by?
[10:58:00] <zeeshan> its just a spring pin usually
[11:01:19] <Jymmm> As long as I can duplicate this 220V@20A circuit, we're good http://i.imgur.com/B0qXNaw.jpg?1
[11:04:44] <CaptHindsight> yes the ebay breakers are SINGLE POLE, they are just slim breakers that fit 2 in the space of 1
[11:04:56] <Loetmichel> sooo, got the first wheel done and mounted... now to the next one... sadly i couldnt get stainless allen key screws, would have looked much nicer... -> http://www.cyrom.org/palbum/main.php?g2_itemId=15969 http://www.cyrom.org/palbum/main.php?g2_itemId=15972 (2 links!)
[11:06:18] <CaptHindsight> here is a Zinsco 2 pole breaker http://www.ebay.com/itm/Zinsco-Style-GTE-Sylvania-Circuit-Breaker-2-Pole-50-Amp-/191690249948?hash=item2ca1a116dc
[11:06:46] <CaptHindsight> the two levers will be ganged together
[11:06:57] <CaptHindsight> NOT independent from each other
[11:10:14] <CaptHindsight> China doesn't hold the exclusive on misleading listings
[11:11:09] <ikcalB> guys, anyone tried http://cnc-plus.de for tool supply? (besides sorotec)
[11:13:23] <Jymmm> CaptHindsight: I was only going by what breaker is in the FRONT service pole (220V@20A feeding a water pump) and duplicating that on the REAR service pole, or at least that's the plan =)
[11:14:30] <CaptHindsight> Jymmm: I highly doubt you'll find a 2 pole slim breaker
[11:14:54] <CaptHindsight> Jymmm: please post that pic of the panel again
[11:15:01] <Jymmm> CaptHindsight: haha
[11:15:29] <Jymmm> CaptHindsight: http://i.imgur.com/B0qXNaw.jpg?1
[11:15:40] <t12> lol
[11:15:42] <t12> unicorn industries?
[11:16:04] <anomynous> woot. cat works in windows. can i do cat file|script in windows? ;D
[11:16:11] <Jymmm> t12: yeah, they were bught out by another company
[11:18:15] <Jymmm> anomynous: Sure, just install linux over windows =)
[11:18:28] <CaptHindsight> Jymmm: Zinsco has those wierd breakers that connect to 2 bus bars at a time
[11:18:49] <Jymmm> CaptHindsight: L1 and L2
[11:18:58] <CaptHindsight> so yeah they have 2 pole in that narrow space
[11:19:36] <CaptHindsight> http://www.ebay.com/itm/Zinsco-Circuit-Breaker-2-Pole-20AMP-/191689394198?hash=item2ca1940816 this one appears to be since the levers are ganged
[11:20:32] <CaptHindsight> http://www.warfieldelectricllc.com/main/images/zinsco_panel.jpg each breaker attaches to both bus bars
[11:20:33] <Jymmm> CaptHindsight: Can I just gang them myself if the bar is missing? That one is push fit not screw
[11:20:59] <Jymmm> the terminals that is
[11:21:10] <CaptHindsight> Jymmm: NO
[11:21:32] <CaptHindsight> two 1 pole breakers do not make a 2-pole breaker
[11:21:33] <Jymmm> ?
[11:21:41] <Jymmm> ah
[11:22:57] <CaptHindsight> for the other panel use a different brand of panel and breaker
[11:23:22] <CaptHindsight> unless the panel is already there
[11:23:32] <Jymmm> CaptHindsight: It already is there
[11:23:42] <anomynous> jymm nope, i dont want to. I really like having all the linux commands and things, but not for just that. Its the same then to install linux, and i need windows too.
[11:23:57] <Jymmm> anomynous: virtual machine
[11:24:28] <Jymmm> CaptHindsight: The front just has a lil metal bonding bar connecting the two together
[11:25:13] <CaptHindsight> Jymmm: the front of what?
[11:25:25] <Jymmm> the front service pole
[11:25:27] <anomynous> Jymmm, i know i can do that, and i do have fedora
[11:27:24] <Jymmm> CaptHindsight: I have two service poles; The front has the meter and that additiaonal 220V@20A circuit. The 200A breaker in there feeds the REAR service pole which has (ironically) a 150A breaker, which then feeds the main panel.
[11:28:01] <enleth> CaptHindsight: TBH most factory ganged multipole breakers *are* several single pole ones with a bar through the levers and different faceplate/markings
[11:28:11] <anomynous> actually im not sure if i need windows anymore. Does fusion work on linux? ;D
[11:28:26] <enleth> but they may be matched to act at the same point in lever travel
[11:29:06] <enleth> Jymmm: ^
[11:29:41] <Jymmm> enleth: I read, I think those ebay breakers are just missing the bonding bar
[11:30:56] <anomynous> http://forums.autodesk.com/t5/fusion-360-ideastation-request-a/linux/idi-p/4530727 linux support is a consideration ;D
[11:31:02] <anomynous> unlikely to happen
[11:32:36] <Jymmm> Is this the same as the ebay ones? http://www.homedepot.com/p/Connecticut-Electric-Thin-20-Amp-Double-Pole-Type-Z-Circuit-Breaker-VPKUBIZ0220/100084924
[11:39:39] <Jymmm> Per this pic http://i.ebayimg.com/images/i/280979359674-0-1/s-l1000.jpg If I understand this correctly... I can either have two 110V@20A circuits (one on L1 the other on L2) -OR- One 220V@20A just depending on how it's wired
[11:44:48] <Jymmm> Oh this is not good... https://www.youtube.com/watch?v=uMV1jmDn3o4
[11:48:32] <Jymmm> I don't have a Zinsco panel, just need to use their 20A breaker, but this is fun.... https://www.youtube.com/watch?v=Q51PSwy4OUY
[11:55:22] <Jymmm> HAHAHAHAHAHA This is pretty good... https://www.youtube.com/watch?t=3&v=P5CJHajjhzk
[11:56:05] <SpeedEvil>
[11:56:37] <Jymmm> SpeedEvil: Squirrel got your tongue ?
[12:00:56] <zeeshan> anyone on their linuxcnc comp right now? :D
[12:10:49] <zeeshan> okay i hope this subroutine stuff works
[12:10:54] <zeeshan> went from 1.2 million lines
[12:11:00] <zeeshan> to 200
[12:11:02] <zeeshan> k
[12:14:49] <CaptHindsight> enleth: so do you feel that Jymmm should just glue a stick (rubber bands, old chewing gum, etc) between the two handles of 2 single pole breakers?
[12:18:56] <Jymmm> CaptHindsight: FWIW, on the existing breaker (in the FRONT service pole going to the water pump) there is a metal bar connecting the two poles together.
[12:19:42] <Jymmm> sorry the pic doesn't show it very well, it's bent sqaure, then a "tab" going into the other pole.
[12:19:53] <CaptHindsight> Jymmm: yes I know, the manufacturer put it there
[12:20:28] <Jymmm> CaptHindsight: Ok, so that bar isn't an "optional" thing ?
[12:20:47] <Jymmm> ...depeing if it's wired 220 or two 110 cicruits?
[12:21:03] <Jymmm> depending*
[12:21:33] <CaptHindsight> the only bar I'm interested in right now is one with scotch
[12:21:38] <CaptHindsight> bbl
[12:28:08] <Jymmm> CaptHindsight: enleth So, is this the "correct" breaker? http://www.ebay.com/itm/Zinsco-20amp-2pole-breaker/171926550892
[12:34:41] <Jymmm> Another... http://www.ebay.com/itm/ZINSCO-GTE-Sylvania-20-Amp-2-Pole-Thin-BREAKER-RC38/220496899846
[12:36:25] <roycroft> people still have those old zinsco panels?
[12:36:48] <Jymmm> roycroft: Just a zinsco 20A breaker, not zinsco panel
[12:38:12] <Jymmm> roycroft: My FRONT service panel, I'm wanting to duplicate the 220V@20A circuit in the REAR service pole http://i.imgur.com/B0qXNaw.jpg?1
[12:38:29] <MrSunshine> nice, was able to melt cast iron in my furnace
[12:38:47] <Jymmm> MrSunshine: Try cesium and magnesuim next ;)
[12:39:07] <Jymmm> MrSunshine: congrats btw
[12:39:38] <roycroft> that panel looks a bit, um, vintage
[12:39:58] <Jymmm> roycroft: fuck vintage, it's 40yo =)
[12:40:06] <Jymmm> I HATE the word vontage anymore
[12:40:12] <Jymmm> vintage*
[12:40:38] <MrSunshine> but its just barely and took ages to melt just like 1dl of cast iron
[12:40:38] <roycroft> it's meant as a polite euphemism for "that's f***ing old!"
[12:40:46] <MrSunshine> need to up the tip on my burner i think =)
[12:41:03] <MrSunshine> but the heat is there, i even melted a mild iron rod inside the furnace to check if i got the temps =)
[12:41:08] <MrSunshine> mild steel
[12:41:14] <Jymmm> roycroft: to hell with being polite, call em as you see em =)
[12:41:31] <Jymmm> MrSunshine: more air flow?
[12:41:48] <MrSunshine> Jymmm: more oil in the same amount of time .. and with that more air flow =)
[12:42:04] <Jymmm> MrSunshine: oil? no idea
[12:42:09] <roycroft> so auber instruments shipped part of my order via fedex, and part via usps
[12:42:22] <MrSunshine> i use home heating oil and a home heating burner in the furnace =)
[12:42:22] <roycroft> no big deal normally, but it's saturday, and both are "out for delivery"
[12:42:37] <Jymmm> roycroft: FedEx does "last mile" via USPS fwiw
[12:42:37] <roycroft> which means i have to wait at home for fedex, and hope they arrive before the post office call window closes
[12:42:52] <MrSunshine> i think i got some bad ass tips for the burner to put in =)
[12:43:01] <roycroft> no, this will be fedex home delivery, which will come in a fedex truck
[12:43:17] <roycroft> i *think* they are supposed to arrive by noon for saturday deliveries
[12:43:23] <roycroft> and the post office call window closes at 1 today
[12:43:27] <roycroft> so i should have enough time
[12:43:39] <Jymmm> roycroft: I've seen as a late at 9pm
[12:43:42] <roycroft> i'm not sure why the order was split - it's a small order
[12:43:49] <roycroft> saturday delivery is different
[12:43:54] <roycroft> i've seen weekday deliveries late
[12:44:15] <roycroft> basically they sent the electronics and the enclousure via fedex
[12:44:22] <roycroft> and the temperature probe via usps
[12:44:33] <roycroft> all shipped from the same warehouse
[12:45:05] <roycroft> and the enclosure and electronics are small - they could have stuffed everything into a medium priority mail box, i think
[12:47:14] <Jymmm> Heh, I kinda like it http://cdn1.bigcommerce.com/n-dvzvde/add46/products/11243/images/34847/40460_ACDCUSA__88775.1431961442.1000.1000.jpg?c=2
[12:58:08] <enleth> CaptHindsight: not unless he knows himself what he's doing and is consciously competent enough to do that safely, which he isn't because he asked. But two 1-pole breakes do indeed "make" a one 2-pole breaker, when the manufacturer does it.
[12:58:28] <enleth> CaptHindsight: yep, nitpicking.
[12:59:33] <roycroft> all is good - fedex arrived
[12:59:36] <archivist> the special bit is the linked fusing in them
[12:59:43] <roycroft> i even have time to take a shower before heading off to the post office
[13:00:47] <roycroft> and that's impressive
[13:01:10] <roycroft> i got an email from fedex saying the package was delivered before the truck pulled away from my house
[13:01:51] <Jymmm> he scanned it on the truck sounds like.
[13:02:08] <roycroft> he scanned it as he handed it to me
[13:02:15] <Jymmm> ah
[13:02:22] <roycroft> i guess there was a 45 secon delay before the email was sent
[13:02:27] <roycroft> second
[13:02:28] <Jymmm> lol
[13:03:10] <roycroft> i can tolerate that
[13:03:31] <Jymmm> roycroft: That's nice of you <grin>
[13:04:53] <Jymmm> I'm trying to understand here...
[13:05:22] <Jymmm> So, the handle tie bars that are on breakers are NOT an optional thing? like shown here... http://www.ebay.com/itm/40A-Zinsco-40-Amp-2-Pole-3-4-BREAKER-RC38-GTE-Sylvania-/390063141109
[13:05:43] <Jymmm> The MUSt be factory installed for tandem operation?
[13:07:01] <Jymmm> I realize this is an old breaker, but I see tie-bars for other breakers available for purchase on their own.
[13:08:58] <archivist> Jymmm, there is another connection, not just the handle
[13:09:44] <archivist> so one which is dropping out due to over current knocks the other off too
[13:10:00] <Jymmm> archivist: This is s 30A (I need 20A), but it doesn't look liek you describe http://www.ebay.com/itm/standard-size-double-pole-30-amp-zinsco-breaker-/252096196944
[13:10:35] <archivist> get a professional to do this work you obviously should not be near it
[13:10:37] <Jymmm> archivist: Right, I totally get that if there is an overload, pop bother breakers. but I thought that is the purpose of the tie bar
[13:10:48] <Jymmm> both*
[13:10:53] <archivist> no the tise is for on
[13:10:57] <archivist> tie
[13:11:46] <archivist> take a dual/three way apart and you see the extra hole and small bit of plastic
[13:11:47] <Jymmm> so the tiebar itself wouldn't throw the other breaker in case of overload?
[13:12:11] <Wolf_> I think the breakers are a little different in 220v countries
[13:13:15] <archivist> there are many kinds of breaker, motor loads, lighting loads etc
[13:13:58] <archivist> you have to learn this stuff to work to your local code
[13:15:08] <Wolf_> they do make removable tie bars for 220/ split 110
[13:15:15] <Jymmm> I'm just trying to duplicate what is on the FROTN service pole to the REAR service pole. This pic shows the tie bars (mine has the square bar, not the rod) http://i.ebayimg.com/00/s/MTA2NlgxNjAw/z/6U4AAOSwFnFV8y3z/$_57.JPG
[13:16:15] <Jymmm> Wolf_: That's kinda what I'm thinking, but I get the impression from CaptHindsight that the tie bar MUST be factory installed
[13:16:39] <archivist> depends on use
[13:16:58] <archivist> when you have to break both it should be factory
[13:17:01] <Jymmm> 220 = install tie bar. 110 = no tie bar
[13:19:09] <Jymmm> archivist: I have no problem breaking both either way (110 or 220)
[13:23:21] <roycroft> what i've been told by an electrician whom i trust is that the breakers with the tie bars are matched at the factory so that they both trip at essentially the same current load, while stand-alone breakers have less strict tolerences
[13:23:41] <roycroft> he recommends always using factory-matched breakers for 2 pole circuits
[13:23:57] <Jymmm> roycroft: Ah, ok. Now THAT makes sense.
[13:24:49] <roycroft> well, the tolerences are probably the same for both the single pole and 2 pole breakers, but if you take two random single pole breakers one might trip at the low end and the other at the high end
[13:24:56] <roycroft> hence the matching
[13:24:59] <roycroft> it's like balancing pistons
[13:25:05] <Jymmm> roycroft: Basically you don't want one rated at 15A but trips at 14A and tied to one that is rated at 15A but trips at 16A which might hold the other one "closed"
[13:25:12] <roycroft> exactly
[13:26:26] <enleth> Jymmm: yeah, roycroft has it right.
[13:27:22] <Wolf_> yeah, i wouldnt use the tie bars on 2 single breakers, only on paired… but I only use QO series stuff on all my installs so I kinda forget about that stuff
[13:27:25] <Jymmm> Yeah, makes total sense. Just needed to understnad the reasonign behind it
[13:27:32] <enleth> Jymmm: and you can buy breakers that are intended to be connected together in arbitrary sets, with connecting bars that can be bought separately from the manufacturer, but those are just made to better standards so that can be safely combined in the field.
[13:28:09] <enleth> *they can
[13:28:56] <Jymmm> Yesh, well, I'm dealign with a 40yo service pole/panel using a 20A Zinsco breaker. Normal does not apply =)
[13:28:59] <roycroft> those generally have little clips that go over the breaker handles
[13:29:12] <roycroft> i think the ones with the steel rods that go through the handles are factory only
[13:29:23] <Wolf_> shit hasn’t changed that much in 40yrs
[13:29:34] <Jymmm> roycroft: I have the 20A version of these (the square metal ties) http://i.ebayimg.com/00/s/MTA2NlgxNjAw/z/6U4AAOSwFnFV8y3z/$_57.JPG
[13:29:43] <Wolf_> only added gfi and arc fault really
[13:29:45] <roycroft> s/40/75 when it comes to breakers :)
[13:29:45] <enleth> Jymmm: those are usually made for industrial use, so that the controls guy can mix and match them as needed without giving a crap whether he's got enough multipole stuff at hand
[13:30:16] <roycroft> we can call breaker panels "mature technology" at this pint
[13:30:17] <roycroft> point
[13:30:37] <Jymmm> roycroft: BRING BACK GLASS FUSES!!!
[13:30:49] <Jymmm> and KNOT AND TUBE too
[13:30:53] <roycroft> what i miss are mercury switches
[13:30:55] <Wolf_> knob
[13:31:03] <roycroft> knob and tube is extremely robust technology
[13:31:15] <Jymmm> roycroft: I have a few mercury switches
[13:31:16] <Wolf_> ^
[13:31:24] <roycroft> primarily due to how paranoid the installers were
[13:31:35] <Wolf_> till you put blow in insulation on top of it
[13:31:35] <Jymmm> lol, glad they were
[13:31:38] <roycroft> 18" of air is an extremely good insulator
[13:32:09] <roycroft> i need to do some frequent high current switching
[13:32:12] <enleth> I had some cast iron distribution panels with solid copper bus bars and screw-in fuses.
[13:32:17] <roycroft> mechanical relays would fail quickly
[13:32:27] <roycroft> the contacts would burn up
[13:32:35] <enleth> 600kg of iron, 25kg of copper and 5sqm of wall for ten circuits.
[13:32:40] <roycroft> ssrs generate too much heat at high current ratings and are not terribly reliable
[13:32:47] <roycroft> mercury switches would be perfect
[13:32:53] <enleth> The scrap paid for a new one and some more.
[13:33:00] <roycroft> but if the mercury gets out it's hazardous
[13:33:28] <roycroft> the correct solution is to design the mercury switches such that the mercury is not able to get out
[13:33:45] <SpeedEvil> roycroft: kinda hard to do if incinderated.
[13:33:46] <roycroft> but the actual solution was to ban them, sadly
[13:34:23] <roycroft> i don't mind banning things that can be dangerous if there is replacemen technology that works just as well
[13:34:47] <enleth> roycroft: I think the way they do it in power distribution is using high-pressure inert gas to blow over the contacts, which are a round copper rod entering a hole in a copper block.
[13:35:01] <enleth> Gas is being blown out of the hole, from the other side of the block.
[13:35:18] <roycroft> that would work
[13:35:43] <roycroft> but it would not scale down economically
[13:35:51] <roycroft> i'm taking about 50a loads
[13:36:14] <roycroft> high current from a light bulb and ipod point of view
[13:36:28] <roycroft> but actually pretty minimal
[13:36:43] <enleth> I think I've seen some GE relays that can switch those kinds of loads without any significant burning of contacts
[13:37:01] <enleth> Looked like they share the switching mechanism with Dilos manual switches.
[13:37:25] <roycroft> for my brew system, which is only 30a per circuit, i use an ssr with a contactor as a safety behind it
[13:37:36] <roycroft> ssrs tend to fail, and fail closed
[13:37:43] <enleth> I had one of those, makes an extremely loud bang when switching but that's because it's got a spring-loaded arc blow-off system
[13:37:53] <roycroft> that would be annoying
[13:37:58] <SpeedEvil> roycroft: switching the contactor after the SSR makes it stupidly reliable
[13:38:18] <roycroft> since i control with a pid controller, and sometimes it cycles more than once/second
[13:38:21] <SpeedEvil> (and opposite on off)
[13:38:28] <roycroft> i don't need a machine gun in my control panel
[13:38:33] <SpeedEvil> roycroft: lies.
[13:38:47] <SpeedEvil> _everyone_ needs a machine gun in their control panel. What about zombies?
[13:38:50] <enleth> I switched it once with an artificial 140A load (it was a 160A model) and the arc getting blown into nothing looks nice.
[13:39:56] <roycroft> my contactors are inline with the ssrs, and i think they're before the ssrs, but i can't see that it matters
[13:40:13] <enleth> Oh, and I still have a 50s ceramic base 4 pole switch that contains a passive arc dissipation system
[13:40:19] <roycroft> the control circuit for my contactors has a manual switch to close the circuit, and it runs through the pid controller
[13:40:39] <roycroft> if i exceed my setpoint by a certain amount the alarm contacts on the pid controller open and shut down the contactor
[13:40:41] <enleth> But there are noticeable burns on the contacts, it's just to keep the arc from staying too long
[13:41:36] <roycroft> but since both the ssr and the contactor need to be closed for current to flow i don't see that their order in the circuit matters
[13:41:57] <roycroft> it's also important to have contactors because ssrs leak current even when "open"
[13:42:23] <roycroft> and for doing maintenance you need to turn off the contactor to be safe
[13:42:47] <SpeedEvil> roycroft: I was meaning in parallel is nice - as you lose the SSR bvoltage drop
[13:42:50] <SpeedEvil> Which is ~1.5V
[13:43:00] <SpeedEvil> And don't need a heatsink so much
[13:43:16] <SpeedEvil> (if you add a thermal fuse for relay failure)
[13:43:34] <enleth> SpeedEvil: actually, the best would be to have one contactor in parallel, and one in series with all of that
[13:43:59] <roycroft> are you talking on the control side?
[13:44:05] <enleth> SpeedEvil: so you use one as an offload that doesn't arc and burn out, and the other one as a safety cutoff in case the SSR fails closed
[13:44:05] <roycroft> i use completely different circuits for the control side
[13:44:20] <Loetmichel> soo, finally mounted second wheelchair "bbs" rim... why is it that every time you need the battery drill/screwdriver its battery is totally drained? -> http://www.cyrom.org/palbum/main.php?g2_itemId=15975
[13:44:25] <enleth> roycroft: no, the power side.
[13:44:48] <enleth> roycroft: you have the contactor in series as a safety cutoff, right?
[13:44:51] <roycroft> yes
[13:45:14] <roycroft> because i don't trust ssrs
[13:45:52] <roycroft> and i can't reliably cycle contactors frequently
[13:45:53] <enleth> roycroft: so the order matters - you should close the SSR last and open it first, so that the contactor is normally operated under no load and doesn't arc at all
[13:46:15] <roycroft> i don't cycle them both
[13:46:26] <enleth> roycroft: but you can add a second contacotr in parallel with just the SSR, as an offload
[13:46:27] <roycroft> what i do is manually turn on the contactor
[13:46:49] <roycroft> then i start the program which cycles the ssr
[13:46:52] <enleth> roycroft: you close the SSR and then close the contactor, which offloads the SSR and lets it cool down
[13:47:12] <enleth> But it shouldn't arc
[13:47:19] <SpeedEvil> enleth: yeah
[13:47:21] <enleth> Actually, they offload each other.
[13:47:45] * SpeedEvil ponders an overheat line.
[13:47:56] <enleth> SSR lets the contactor act with no arcing, contactor lets the SSR pass smaller continued currents
[13:48:02] <SpeedEvil> lots of thermal fuses in series on an input relay to the device.
[13:48:22] <roycroft> hmm
[13:48:29] <roycroft> i'd have to ponder that a bit more
[13:48:39] <roycroft> it would have the disadvantage of being very noisy, though
[13:48:52] <enleth> roycroft: yep.
[13:48:53] <roycroft> my contactors make a fairly loud "clunk" sound when they switch
[13:49:02] <roycroft> so i would have the machine gun problem again
[13:49:26] <SpeedEvil> It's a real pity high voltage FETs suck a bit
[13:49:27] <roycroft> my current solution is to have spare ssrs in a drawer right below the control panel
[13:49:35] <SpeedEvil> MOSFET SSRs would be awesome.
[13:49:38] <roycroft> and if i have an ssr fail i can swap it out in 10 minutes at most
[13:49:38] <enleth> don't have to tell me, I'm fiddling with a mill that has ballscrew brakes
[13:49:46] <SpeedEvil> But only if they were ~0.2V or so Vf
[13:50:00] <enleth> they make a loud bang every time an axis stops and starts
[13:50:17] <roycroft> consider that in my brew system i have two pid-controlled circuits
[13:50:24] <roycroft> so i would actually have two machine guns in the control panel
[13:50:34] <SpeedEvil>
[13:50:41] <SpeedEvil> why on earth are you doing it so fast?
[13:50:50] <roycroft> the pid controller does it
[13:50:57] <roycroft> i need to hold the temperature very pecisely
[13:51:07] <roycroft> i prefer it not to vary by more than 0.1 degree c
[13:51:27] <roycroft> the pid controllers are on/off switching only
[13:51:33] <roycroft> they don't vary the current in the heating elements
[13:51:45] <roycroft> so to heat at 2/3 power they switch on for two cycles and off for 1 cycle
[13:51:59] <roycroft> and they do it at a very fine granularity
[13:52:05] <roycroft> like 2 cycles/second
[13:52:43] <SpeedEvil> what are you heating?
[13:52:54] <roycroft> i have indicators on my control panel that show me when current is flowing, so i can watch the on/off blinking
[13:53:03] <SpeedEvil> I was assuming 'brew' meant a large vessel
[13:53:08] <roycroft> water in one vessel and beer wort in the other
[13:53:11] <roycroft> 58L
[13:53:13] <roycroft> not really large
[13:53:14] <SpeedEvil> ...
[13:53:15] <roycroft> but not tiny either
[13:53:15] <SpeedEvil> lol
[13:54:23] <roycroft> www.zymurgasm.com/NewBrewSystem/BrewDay2
[13:54:24] <SpeedEvil> If the heat loss/gain is 24kW, then you need about that fast
[13:54:29] <roycroft> that shows most of the brew system
[13:54:39] <SpeedEvil> This seems unlikely.
[13:54:48] <SpeedEvil> What power is your heater?
[13:55:01] <roycroft> one is 6000w, the other is 1400w
[13:55:13] <SpeedEvil> hmm
[13:55:15] <roycroft> i cannot control the frequency of the pid cycles
[13:55:26] <SpeedEvil> Wierd controller
[13:55:29] <Wolf_> wonder if the temp sensor is that accurate
[13:55:30] <roycroft> i'm just telling you what they do
[13:55:34] <roycroft> it is
[13:55:39] <SpeedEvil> For SSR, it isn't unreasonable
[13:55:46] <roycroft> i've compared its readings with a nist-calibrated thermometer
[13:56:19] <roycroft> but even if it weren't, i don't need it to be dead on accurate
[13:56:24] <roycroft> i need it to be dead on consistent
[13:56:55] <roycroft> it can be off by a degree, but if it's always off the same amount i'm fine
[13:57:06] <roycroft> that's better than averaging spot on but wandering by 0.5 degree
[13:58:19] <roycroft> i design a recipe, brew it, take careful brewhouse and fermentation notes, and tasting notes
[13:58:30] <roycroft> then i adjust the recipe based on the tasting notes for my next batch
[13:58:47] <roycroft> i can usually refine a recipe to get exactly what i want in 3-4 batches, and then i can brew it reliably after that
[13:59:04] <roycroft> as long as i have tight process control
[13:59:53] * roycroft needs to head off to the post office now
[15:08:56] <MrSunshine> hmm i need a nice source of cast iron :/
[15:09:06] <MrSunshine> that is preferably breakable with sledge hammer
[15:20:01] <anomynous> go buy a lump from a job shop? ;D
[15:21:13] <Wolf_> lawnmower engine blocks?
[15:21:33] <roycroft> mrsunshine: see that big machine over in the corner of your shop with the name "bridgeport" on it?
[15:21:40] <roycroft> take your sledge hammer over there
[15:21:44] <roycroft> you'll get lots of nice cast iron
[15:22:10] <MrSunshine> yeah!
[15:22:12] <MrSunshine> good idea! =)
[15:23:05] <roycroft> plus, you'll finally be able to move it without hiring helpers
[15:23:08] <roycroft> so it will save you money
[15:23:23] <Wolf_> go shopping at harbor freight, lot of cheap cast iron there
[15:23:41] <roycroft> he used the word "nice"
[15:26:00] <roycroft> you can also go over to your neighbor's house
[15:26:05] <roycroft> the one with the oldsmobile tank
[15:26:23] <roycroft> convert his engine from a v8 to a v6 and he'll save some money on fuel
[15:26:36] <roycroft> it would be a nice favor
[15:31:33] <anomynous> thats not a bad idea. A scrapyard
[15:37:39] <anomynous> how much does cast iron cost?
[15:37:58] <anomynous> some kind of cast iron ;)
[15:38:07] <zeeshan-mill> can i please get some help with g10 p2
[15:38:13] <zeeshan-mill> it's not working how i was thinking it should work
[15:38:20] <zeeshan-mill> i set my work piece origin (g54)
[15:38:37] <zeeshan-mill> now im trying to offset the X by 2"
[15:38:46] <zeeshan-mill> but when i do g10 l2 p1 x2.0
[15:39:04] <zeeshan-mill> it offsets it relative to the machine origin, not the current g54 position (this is what the command is supposed to do)
[15:39:12] <zeeshan-mill> can someone tell me how i can move it relative to the current position ?
[15:39:37] <zeeshan-mill> G10 L2 Pn does not change from the current coordinate system to the one specified by P, you have to use G54-59.3 to select a coordinate system.
[15:39:43] <zeeshan-mill> ^ how can i do exactly that!!
[15:40:35] <jdh> add the G<whatever> to your code
[15:40:46] <jdh> g92 might do what you want also, but it confused me.
[15:41:09] <zeeshan-mill> huh
[15:41:16] <zeeshan-mill> have multiple parts so i cant use g92
[15:42:31] <jdh> make your code a sub, call it multiple times while setting g55/g56/etc
[15:42:33] <zeeshan-mill> ill give an a more solid example
[15:42:36] <malcom2073> zeeshan-mill: http://www.cnccookbook.com/CCCNCGCodeG54G92WorkOffsets.htm
[15:42:44] <anomynous> want to shift coordinate system? g52?
[15:42:55] <zeeshan-mill> currently my g54 y offset is 5.7542
[15:43:01] <zeeshan-mill> i want it to be 7.7542
[15:43:05] <zeeshan-mill> but i dont want to do the math
[15:43:26] <zeeshan-mill> i want to be able to type g10 l2 p1 y2.
[15:43:30] <zeeshan-mill> to do exactly that
[15:43:33] <zeeshan-mill> but it doesnt work like that
[15:43:53] <malcom2073> zeeshan-mill: Switching to relative coordinates doesn't do it?
[15:44:03] <zeeshan-mill> there is no g52 in linuxcnc
[15:44:14] <jdh> the above URL describes multiple options to do what you want.
[15:44:32] <anomynous> then rapid to where your zero is and press the measure button ;D
[15:44:47] <zeeshan-mill> jdh no it doesnt.
[15:44:56] <zeeshan-mill> m98 m99 doesnt work on linuxcnc
[15:45:00] <zeeshan-mill> lol anomynous
[15:45:01] <jdh> it does, you are just confused about what you want.
[15:45:02] <zeeshan-mill> cant do that
[15:45:12] <zeeshan-mill> i know exactly what i want!
[15:45:15] <zeeshan-mill> i just told you what i want
[15:45:28] <jdh> yes, you are fixated on a solution instead of the problem.
[15:45:40] <zeeshan-mill> ??
[15:45:45] <zeeshan-mill> dude if you read that page
[15:45:48] <zeeshan-mill> youd see theyre using g52
[15:45:50] <zeeshan-mill> and g92
[15:45:54] <zeeshan-mill> why are you arguing with me for no reason
[15:46:13] <zeeshan-mill> if you dont know, dont answer
[15:46:14] <zeeshan-mill> please!
[15:46:28] <malcom2073> Why can't you G92 offset, then zero it out after your subroutine is done?
[15:46:39] <malcom2073> zeeshan-mill: Then go google. Nobody can read your mind.
[15:46:45] <zeeshan-mill> you dont need to read my mind
[15:46:48] <zeeshan-mill> i said exactly what i needed
[15:46:49] <malcom2073> We're offering suggestons and trying to help.
[15:46:53] <zeeshan-mill> i dont want a work around solution
[15:46:58] <zeeshan-mill> and i cant use g92
[15:47:02] <zeeshan-mill> cause that works great for 2 parts
[15:47:04] <zeeshan-mill> not 5.
[15:47:21] <zeeshan-mill> my cam uses g52 also
[15:47:32] <malcom2073> Sounds like you should implement G52 in linuxcnc :-P
[15:47:36] <malcom2073> Time to start coding!
[15:47:39] <zeeshan-mill> i changed the post processor to handle g10
[15:47:44] <zeeshan-mill> but its not offsetting right
[15:51:19] <zeeshan-mill> im just gonna do awork around for now
[15:51:30] <zeeshan-mill> since i know the current Y offset for g54
[15:51:34] <zeeshan-mill> im just gonna rmember it :P
[15:51:42] <zeeshan-mill> and add / subtract to it
[15:51:54] <malcom2073> Need variables!
[15:51:57] <zeeshan-mill> but when i get more time
[15:52:02] <zeeshan-mill> i will definitely try to implement g52
[15:52:08] <jdh> why not just set it for g55/g56/etc and change coord system?
[15:52:38] <zeeshan-mill> jdh because its not shifting the current offset
[15:52:43] <zeeshan-mill> youd have to manually set those up
[15:53:14] <jdh> G10 L2 doesn't change them?
[15:53:20] <zeeshan-mill> it does
[15:54:33] <zeeshan-mill> https://www.dropbox.com/s/tf38lqlsmawyopo/op4_multiple_rev4.ngc?dl=0
[15:54:36] <zeeshan-mill> see how it is laid out
[15:55:25] <zeeshan-mill> id have to look into how to make it consistent so that it doesnt crash into the piece
[15:55:30] <zeeshan-mill> when doing work offsets
[15:56:43] <jdh> you reallly like g54.
[15:57:06] <jdh> g55 feels neglected
[15:57:16] <zeeshan-mill> jdh for a good reason man..
[15:57:25] <zeeshan-mill> you have like 10 coordinate systems in linuxcnc
[15:57:33] <zeeshan-mill> in the future i have a fixture that has 25 parts on it
[15:57:41] <zeeshan-mill> changing the coordinate system for each one doesnt make sense
[15:57:43] <zeeshan-mill> youd wanna shift it
[16:00:14] <malcom2073> This is why we use math (and you make fixtures on even numbers :P )
[16:03:02] <anomynous> cool. its possible to call python code from gcode. Its so much better than fanuc macro b ;D
[16:11:38] <Tom_itx> zeeshan, i'm using G10 as a halui button in my ini if that would help
[16:12:31] <Jymmm> Even numbers... 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, etc
[16:12:43] <Jymmm> malcom2073: Even numbers... 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, etc
[16:13:04] <Tom_itx> gimme all the prime numbers now
[16:13:51] * Jymmm slaps Tom_itx with π to a million digits!!!
[16:15:27] <Tom_itx> zeeshan,
[16:15:30] <atom1> MDI_COMMAND = G10 L20 P1 X0
[16:15:31] <atom1> MDI_COMMAND = G10 L20 P1 Y0
[16:15:31] <atom1> MDI_COMMAND = G10 L20 P1 Z0
[16:15:45] <Jymmm> CaptHindsight: Ok, got a double pole breaker coming... http://www.ebay.com/itm/181872562658
[16:15:46] <Tom_itx> after i set the G54 offset that will send it there
[16:16:07] <Tom_itx> so set your G54 X value offset then send it there to test it
[16:17:22] <Tom_itx> 5221-5230
[16:17:22] <Tom_itx> Coordinate System 1, G54 for X, Y, Z, A, B, C, U, V, W & R. R denotes the XY rotation angle around the Z axis. Persistent.
[16:17:30] <Tom_itx> http://linuxcnc.org/docs/2.6/html/gcode/overview.html#sec:parameters
[16:17:55] <Tom_itx> so you would want the 5221 memory location for X
[16:18:02] <Tom_itx> write the new value there
[16:18:27] <Tom_itx> that page should tell you how
[16:19:04] <Tom_itx> i have little experience doing that but i'm relatively sure it can be done
[16:23:46] <Tom_itx> it could be as simple as: #5221 = newXvalue
[16:24:44] <Tom_itx> A parameter setting does not take effect until after all parameter values on the same line have been found. For example, if parameter 3 has been previously set to 15 and the line #3=6 G1 X#3 is interpreted, a straight move to a point where X equals 15 will occur and the value of parameter 3 will be 6.
[16:25:13] <Tom_itx> so set it on a line by itself
[16:25:45] <Tom_itx> http://linuxcnc.org/docs/2.6/html/gcode/overview.html#_numbered_parameters_a_id_sub_numbered_parameters_a
[16:26:54] <os1r1s> Tom_itx: Check it out https://www.dropbox.com/s/gpk4fgux2i4itfr/slsrook1.jpg
[16:26:56] <Tom_itx> The # character takes precedence over other operations, so that, for example, #1+2 means the number found by adding 2 to the value of parameter 1, not the value found in parameter 3. Of course, #[1+2] does mean the value found in parameter 3. The # character may be repeated; for example ##2 means the value of the parameter whose index is the (integer) value of parameter 2.
[16:27:35] <Tom_itx> os1r1s, did you machine that?
[16:27:45] <os1r1s> Tom_itx: No. Done on an SLS printer
[16:27:50] <Tom_itx> ahh
[16:27:54] <Tom_itx> looks pretty good
[16:28:10] <os1r1s> Tom_itx: https://www.dropbox.com/s/d14yptgibf32wfa/slsrook2.jpg
[16:28:20] <os1r1s> The stairs are cool :)
[16:28:31] <Tom_itx> yeah
[16:29:13] <Tom_itx> zeeshan-mill, i think that explains how to do it and you can do math on it if you follow the directions
[16:29:49] <Tom_itx> so put that in your main gcode file and call your part in a sub
[16:31:22] <Tom_itx> it says numered parameters are persistent so you would need to reset it back to the first one upon ending the program
[16:32:15] <zeeshan-mill> let me read from upstairs
[16:32:15] <zeeshan-mill> brb
[16:34:54] <Tom_itx> it may be as simple as: #5221 = #5221 + 3
[16:35:40] <Tom_itx> i'm not familiar with the syntax but i think that might work
[16:36:00] <Tom_itx> bak in a few...
[16:47:00] <malcom2073> Wolf_Mill: https://scontent-iad3-1.xx.fbcdn.net/hphotos-xpf1/t31.0-8/12015185_1137030969644616_6143717825607374485_o.jpg
[16:47:15] <malcom2073> CoG is about right to lift it by that point, it may be ok with just the engine crane
[16:47:23] <Wolf_Mill> cool
[16:47:39] <malcom2073> That strap is wrapped around the front fwiw heh, then crossed under the motor
[16:49:24] <zeeshan> Tom_itx: nice
[16:49:36] <zeeshan> so its as simple as replacing the g10 l2 p1 to
[16:49:58] <zeeshan> #5221 = X5.00 or whatever
[16:50:14] <zeeshan> actually its more like
[16:50:19] <zeeshan> like yorue saying.
[16:50:26] <zeeshan> #5221 = #5221+3
[16:50:28] <zeeshan> will try it out
[16:51:52] <Tom_itx> and that memvar is persistent
[16:52:26] <Tom_itx> some older machines had their G5x offsets using those variables
[16:52:37] <Tom_itx> the operator had to know where they were
[16:54:34] <Tom_itx> then you can loop and call your program as a sub
[16:55:15] <zeeshan> persistent meaning that
[16:55:16] <XXCoder> jeez
[16:55:25] <Tom_itx> it will stay set upon power off
[16:55:25] <XXCoder> it was one of worse unrestful sleep I ever had
[16:55:29] <XXCoder> cold sucks
[16:55:30] <zeeshan> ah
[16:55:45] <Tom_itx> just like your G54 does now
[16:56:07] <Tom_itx> then you can use your G54 inside the sub as it is now
[16:56:33] <zeeshan> does anyone know if a 7/8 forstener bit is common
[16:56:34] <zeeshan> at home depot
[16:56:39] <zeeshan> as an individual piece
[16:56:59] <Praesmeodymium> I got my cheap ass forsteners from harbor freight I think
[16:57:19] <zeeshan> yes but at home depot?
[16:57:34] <Praesmeodymium> nvm
[17:00:22] <Tom_itx> zeeshan i don't see why not
[17:01:03] <Tom_itx> http://www.homedepot.com/s/7%252F8%2520Forstener%2520bit?NCNI-5
[17:04:03] <roycroft> i've never seen forstner bits at home depot
[17:04:18] <roycroft> if you have a woodcraft or lee valley near you they would carry forstner bits
[17:04:37] <Tom_itx> homedepot or ACE hardware both have them here
[17:04:45] <Tom_itx> lowes probably does too
[17:05:05] <roycroft> perhaps, but if you got one at lowe's it would be made of pot metal with plastic mixed in
[17:05:12] <roycroft> you'd be better off with one from hf
[17:06:22] <roycroft> but if you can't find a forstner bit you can use a end mill
[17:06:47] <Deejay> gn8
[17:06:55] <Tom_itx> gn9
[17:11:37] <Jymmm> roycroft: Whole section of em http://www.homedepot.com/b/Tools-Hardware-Power-Tool-Accessories-Drill-Bits-Forstner-Bits/N-5yc1vZc90r/Ntk-SemanticSearch/Ntt-forstner%2Bbit
[17:12:57] <roycroft> oh, and they do have some of those at my local store
[17:13:02] <roycroft> i haven't ever seen them there
[17:13:16] <roycroft> but i've never looked for them either, as i have a nice set of forstner bits
[17:13:24] <Jymmm> roycroft: Yeah, I know. HD carries less and less each time I go
[17:14:05] <roycroft> there are hardly any tools or tooling that i buy at hd or similar stores these days
[17:14:22] <roycroft> after 40+ years of buying that stuff i have pretty much all the consumer grade stuff there is to have
[17:14:37] <Jymmm> roycroft: The LAST tool I bought from HD was a dewalt 6" philips bit for my drill
[17:15:17] <roycroft> i buy screwgun bits from eugene fastener usually, for a fraction of what the big box stores charge
[17:15:23] <roycroft> drill bits, etc. i get from enco
[17:16:34] <Jymmm> No, I mean this... http://www.amazon.com/PHILLIPS-SCREW-DRIVER-quick-release/dp/B000VNLM1W
[17:17:16] <roycroft> yeah
[17:17:20] <roycroft> i buy those in bulk at eugene fastener
[17:17:33] <roycroft> for the 6" ones, "bulk" is a half dozen for me
[17:17:40] <Jymmm> ah
[17:17:44] <roycroft> 1-3/4" ones i buy in packs of 25
[17:18:05] <roycroft> and i don't buy them that often
[17:18:21] <roycroft> when i was a building contractor i would buy them all the time, but i don't go through as many now
[17:18:23] <Jymmm> I've bought ONE, has lasted me for years
[17:18:44] <Jymmm> but I'm not as abusive as contractors are =)
[17:18:44] <roycroft> yes, the 6" ones tend to last, because you don't use them that often
[17:19:10] <Jymmm> It's constantly chucked in my drill, hate maring up things
[17:19:11] <roycroft> it's not necessarily abusive
[17:19:16] <roycroft> you can call it "hard use"
[17:19:20] <Jymmm> =)
[17:19:50] <Jymmm> thats why they come in 25 packs =)
[17:19:57] <XXCoder> "experenced drill"
[17:20:03] <roycroft> time is money, and it can be cheaper to push tooling like that hard and replace it often than to slow down and make it last
[17:20:51] <roycroft> also, having spares on hand tends to make one less concerned about the one that's currently in use
[17:21:05] <roycroft> if you only have one and it's a half hour to make a run to replace it you're going to take good care of it
[17:21:36] <SpeedEvil> Yeah. Whereas if you've got two, you can break one, be very careful with the other and break it in another three minutes.
[17:22:00] <roycroft> and if you have 25, you can make it 'til lunch before you have to do a store run
[17:22:37] <roycroft> or, generally, the gopher will be back replacements before you burn up the last one
[17:22:42] <roycroft> back with
[17:47:55] <Tom_itx> zeeshan, the 'yourmachine'.var file stores the parameters so you could set it and edit that file to see it change
[17:48:03] <XXCoder> hey guys
[17:48:28] <XXCoder> do this SFU1204 let me how far it moves with one rotation or whatever?
[17:48:34] <XXCoder> ball screw
[17:48:43] <Praesmeodymium> 4mm
[17:48:51] <XXCoder> 4 mm per rotation?
[17:49:03] <Praesmeodymium> thats the 04 at the end of the part #
[17:49:07] <Tom_itx> 12mm diameter screw 4mm pitch
[17:49:32] <XXCoder> it also says its possible it has newer 1606 so I guess 16mm diameter 5 mm per rotation
[17:49:38] <XXCoder> er 1605
[17:49:47] <Tom_itx> or fathoms
[18:32:20] <zeeshan> hojme depot is frigging garbage
[18:32:22] <zeeshan> lowes kicks ass
[18:32:30] <zeeshan> Tom_itx: will do in a bit after eating
[18:33:49] <XXCoder> lowes is awesome yeah, if bit high priced
[18:34:03] <zeeshan> they got everything though
[18:34:06] <zeeshan> :D
[18:34:11] <XXCoder> not really
[18:34:14] <furrywolf> big box stores are garbage.
[18:34:19] <XXCoder> they dont have endmills and such
[18:34:27] <furrywolf> if you think lowes has everything, you've never been to a proper hardware store.
[18:34:27] <furrywolf> lol
[18:34:42] <furrywolf> lowes/home depot have the LEAST.
[18:34:47] <zeeshan> um
[18:34:52] <zeeshan> at leas tthey have regular fasteners
[18:34:54] <zeeshan> unlike homedepot
[18:34:59] <zeeshan> whcih only carries the scum of the scum
[18:35:08] <zeeshan> XXCoder: i mean general hardware stuff
[18:35:20] <furrywolf> last time I was at a lowes, all they had was fasteners in little bags, no bulk bins, trays, etc.
[18:35:37] <XXCoder> local one has bulk stuff
[18:35:38] <zeeshan> dude here its so organized
[18:35:44] <zeeshan> its like 500 ft of fasteners
[18:35:47] <zeeshan> ill take a pic next time
[18:36:41] <trentster> man! - all finally working and what a learning curve :-)
[18:36:44] <trentster> https://monosnap.com/file/ZVZj9Oc4ybXdQHgykeaPzkQXYpKscl
[18:37:14] <trentster> I can see how creating the panels and butoons + scripts can become strangely addictive
[18:42:39] <jdh> did you get the probe working?
[18:45:54] <MacGalempsy> Hello
[18:47:25] <MacGalempsy> trentster: I hear you on the learning curve thing
[18:49:49] <trentster> MacGalempsy: indeed
[18:50:00] <trentster> jdh: yeah probe is working
[18:50:15] <MacGalempsy> im down to about a half dozen pins that read, but need logic.
[18:50:20] <trentster> auto z height probe is it least
[18:50:27] <jdh> cool
[18:51:25] <MacGalempsy> any video?
[18:51:34] <trentster> next up today is adding USB Camera/microscope and laser level lines that get controlled via panel.
[18:51:54] <MacGalempsy> what are the laser lines for?
[18:52:11] <trentster> tomorrow - gonna mill an edge finder plate and figure out the routines for edge finding and hole centering
[18:52:25] <Wolf_Mill> everything is better with lasers
[18:53:00] <XXCoder> I want tool length finder plate evenually
[18:53:13] <trentster> MacGalempsy: laser crosshairs I can use to quickly find an edge or center or to check that a piece of non essential material like acrylic is clamped straight
[18:53:14] <MacGalempsy> so one of the guys in my makerspace is doing a blacktooth laser project. he was like oh, linuxcnc will be easy. Last night he started asking for help.
[18:53:16] <zeeshan> tool length setter would be sweet!!
[18:53:40] <XXCoder> zeeshan: its little more than plate and detect electricity
[18:53:50] <XXCoder> zeeshan: great for machines that dont have tool changer
[18:54:16] <zeeshan> why not for ones with atc?
[18:54:29] <MacGalempsy> zeeshan: https://www.sparkfun.com/products/13332
[18:54:40] <trentster> gonna try make one of theses a mini one out of 12mm thick plate stock http://www.themakersguide.com/home/products/triple-edge-finder-2
[18:54:41] <Wolf_Mill> you set the tool height on a setup plate for a atc
[18:54:48] <zeeshan> MacGalempsy: i want sopmething more springy
[18:54:51] <zeeshan> so you can smash the tool into it
[18:54:54] <zeeshan> kinda like a switch
[18:55:04] <XXCoder> MacGalempsy: nice!
[18:55:09] <XXCoder> nicer than what I considered
[18:55:44] <MacGalempsy> https://www.sparkfun.com/products/13230
[18:55:57] <MacGalempsy> https://www.sparkfun.com/products/10245
[18:56:10] <MacGalempsy> that one is pretty springy, just machine a housing
[18:56:27] <XXCoder> cheap
[18:56:45] <MacGalempsy> yeah, get both and you are ready to send a signal to probe-in
[18:57:00] <MacGalempsy> there was a smaller load sensor
[18:57:11] <zeeshan> i feel like hitting that with a carbide end mill
[18:57:16] <zeeshan> at 10 ipm will break the tip
[18:57:23] <trentster> Yeah - Linuxcnc has a steep learning curve - I plan to write a guide and a screencast video when I am done showing folks how to do it. There should be an easy resource for folks to get started and have a running machine with a working touch of plate without having to wade through and decipher hundreds and hundreds of manual pages + Google
[18:57:33] <MacGalempsy> zeeshan: its a touchoff, not a scrum
[18:57:59] <zeeshan> oh you manually got into it?
[18:58:14] <zeeshan> got = jog
[18:58:25] <XXCoder> zeeshan: or make script to do it for you
[18:58:33] <zeeshan> no i dont think im being clear
[18:58:36] <trentster> By any chance, does anyone here have cad files for a triple edge finder?
[18:58:42] <XXCoder> someone using linuxcnc and basic electric plate made script to do it
[18:58:44] <zeeshan> when youre homing your axis, the springiness in a microswitch is good
[18:58:49] <zeeshan> i allows overshoot
[18:58:52] <zeeshan> if you just put a load cell
[18:58:55] <zeeshan> there is no room for overshoot?
[18:59:11] <trentster> why would you want overshoot?
[18:59:11] <XXCoder> lemme find link
[18:59:15] <MacGalempsy> the load cell will need the amplifer or else it will not work
[18:59:18] <zeeshan> you dont want overshoot
[18:59:19] <XXCoder> trentster: because shit happens
[18:59:26] <zeeshan> but if youre probing at 10ipm or so
[18:59:26] <Wolf_Mill> zeeshan: how about making a optical beam to set toolhight
[18:59:32] <zeeshan> there will be always overshoot
[18:59:47] <zeeshan> Wolf_Mill: pro systems are like that
[18:59:52] <MacGalempsy> zeeshan: I was thinking about a circle body with a spring and a button in a solid body
[18:59:54] <trentster> I am going to install proximity switches today, in theory they should allow for a minute ammount of overshoot
[19:00:11] <Wolf_Mill> prox switches are odd
[19:00:24] <XXCoder> zeeshan: http://www.cnccookbook.com/img/OthersProjects/TouchPlate.jpg
[19:00:26] <jdh> I had chips trip my prox limit switch
[19:00:29] <MacGalempsy> use a really stiiff spring, then take a good pass over with a surface grinder
[19:00:36] <zeeshan> XXCoder: there is no room for overshoot
[19:00:37] <zeeshan> with that mechaniusm
[19:00:48] <XXCoder> zeeshan: yeah have to be really slow on z find
[19:00:52] <trentster> Wolf_Mill: yeah and they generally need some circuitry to stop false triggers
[19:01:01] <zeeshan> doesnt that defeat the purpose of using that to set tool height?
[19:01:02] <zeeshan> :P
[19:01:09] <Wolf_Mill> just need to think smart on the install
[19:01:10] <MacGalempsy> I was thinking those as tool setter, not edge finder
[19:01:24] <XXCoder> https://www.youtube.com/watch?v=yR_UfXhfOoA
[19:02:00] <trentster> XXCoder: why not just use a center finder plate as your touch off tool - easier that way and have 1 tool that can do many jobs
[19:02:14] <MacGalempsy> XXCoder: sorry that is a mach3 video
[19:02:18] <XXCoder> trentster: yeah
[19:02:19] <MacGalempsy> lol, cant watch it
[19:02:22] <Wolf_Mill> http://i.imgur.com/WUrLcnK.jpg my prox sensor is in that alum U channel under the vice
[19:02:27] <Wolf_Mill> facing down
[19:02:43] <XXCoder> trentster: theres this nice 2 inch touch light up tool thingy but its expensive
[19:02:43] <jdh> much better than mine.
[19:02:58] <trentster> Wolf_Mill: that smart - I think I will look at putting mine there as well
[19:03:07] <jdh> I tested it by piling a bunch of chips on it and it was fine. Then I made a bunch of really small chips and they hit it.
[19:03:30] <MacGalempsy> i got the interface/ amplifier for my renishaws coming this week
[19:03:39] <zeeshan> https://www.youtube.com/watch?v=9nVzKTU1Jkk
[19:03:41] <zeeshan> tormach one is nice
[19:03:45] <zeeshan> has give in it
[19:03:46] <trentster> altho my machine is a cnc router not a lathe or mill so I dont expect huge metal chipload to be flying all over the place - and besides will only be cutting aluminium which is almost impossible to trip a prox with
[19:03:53] <XXCoder> zeeshan: http://www.edgetechnologyproducts.com/pro-touch-off-gage/
[19:04:04] <jdh> trentster: mine tripped on Al chips
[19:04:05] <XXCoder> way too tall for my machine but maybe good for you.
[19:04:11] <zeeshan> its manual :P
[19:04:36] <zeeshan> http://www.tormach.com/product_tts_tool_setter.html
[19:04:39] <zeeshan> im liking
[19:04:49] <trentster> jdh: interesting did you literally have to pile up a bunch of them onto the switch or did it trip during normal chip operations?
[19:04:52] <Loetmichel> trentster: i "tripped" my main fuse with al chips tho
[19:05:04] <XXCoder> zeeshan: I guess it has output
[19:05:06] <MacGalempsy> zeeshan: $800!
[19:05:13] <XXCoder> so can connect to one of pins
[19:05:24] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=10609 <- holes in stepper driver enclosures are a bad idea ;)
[19:05:28] <jdh> trentster: I tested by piling up big chips, no problem. I was cutting something with small chips and it tripped
[19:05:30] <MacGalempsy> yeah one output and a light
[19:05:33] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=10606
[19:05:40] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=10603
[19:05:41] <Wolf_Mill> mine pick up alum http://i.imgur.com/qT8km3q.jpg
[19:05:45] <Loetmichel> :-)
[19:05:56] <MacGalempsy> maybe we should start an opensource design, so we can all make one
[19:05:59] <XXCoder> $800 so cheap, it barely doubles my machine cost lol
[19:06:14] <MacGalempsy> hahahaha
[19:06:15] <zeeshan> hoinestly
[19:06:21] <zeeshan> im just gonna use a lever style switch
[19:06:23] <zeeshan> they work good enough
[19:06:50] <MacGalempsy> its funny how we are willing to go for 10000ths accuracy, then use a crappy touchoff process
[19:07:01] <trentster> zeeshan: in theory proximity's are more repetable and accurate
[19:07:03] <MacGalempsy> i guess that is why they call it trial machining
[19:07:13] <zeeshan> trentster: key word in theory
[19:07:13] <zeeshan> :P
[19:07:20] <XXCoder> MacGalempsy: at work I just use 2 of 123 blocks and slide under tool and rise so on
[19:07:26] <zeeshan> my mill has a combination of both
[19:07:36] <trentster> Wolf_Mill: thats quite a large and oddly shaped chip you have there :P
[19:07:37] <jdh> I use a gauge pin and jog
[19:07:39] <zeeshan> 5 tenths repeatabiliiy no prob
[19:07:39] <XXCoder> for Z for part, use indictor on that blocks top then on part
[19:07:40] <MacGalempsy> a better rundown of the touchoff file:///C:/Users/Aaron/Downloads/DS10000_TTS_Electronics_0513A.pdf
[19:07:50] <XXCoder> then do (part z) - (block z)
[19:07:51] <MacGalempsy> http://www.tormach.com/uploads/50/DS10000_TTS_Electronics_0513A-pdf.html
[19:08:48] <jdh> http://www.omiocnc.com/media/wysiwyg/products/x6-2200usb/13-package.jpg
[19:08:49] <Loetmichel> for the limit/reference swithces i had surprisingly good results with simple "microswitches"
[19:09:01] <jdh> my chinese router came with the above tool setter. Never tried it though
[19:09:05] <trentster> zeeshan: since mine has zero mechanical or proximity at the moment -I should probably reserve judgement and theory until I actually put them in ;-)
[19:09:11] <Loetmichel> like these: http://www.cyrom.org/palbum/main.php?g2_itemId=560
[19:09:28] <Loetmichel> but only when moved on fromthe side by a 45° ramp
[19:09:48] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=7414
[19:09:56] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=7411
[19:10:00] <Loetmichel> like this
[19:10:14] <Loetmichel> had repeatablility belwo 1/100mm
[19:10:18] <Loetmichel> below
[19:10:31] <Loetmichel> s/below/better than
[19:10:46] <MacGalempsy> does everyone here climb cut with their cnc?
[19:10:59] <Loetmichel> whats "climb cut"?
[19:11:02] <zeeshan> ofcourse
[19:11:04] <zeeshan> =P
[19:11:14] <Wolf_Mill> i do both climb and coventional
[19:11:22] <MacGalempsy> Loetmichel: fluts spin into the workpiece
[19:11:59] <Loetmichel> i only do that for cutting 3 and 6mm styrofoam sheets for model planes
[19:12:12] <Loetmichel> because otherwise they would lift off the table
[19:12:51] <Loetmichel> anything else i do with normal fluted cutters
[19:13:35] <MacGalempsy> https://www.youtube.com/watch?v=6hVUELaxNn8
[19:13:43] <MacGalempsy> that is a nice plate design
[19:14:14] <Wolf_Mill> climb vs conventional, has nothing to do with t flute direction http://www.destinytool.com/uploads/2/4/9/5/24954651/2748179_orig.jpg
[19:15:01] <zeeshan> langauge barrier :P
[19:15:23] <zeeshan> Wolf_Mill: technically it does :P
[19:15:27] <zeeshan> if youre using a lh end mill
[19:15:29] <zeeshan> itll be opposite :P
[19:15:34] <Wolf_Mill> lol
[19:19:14] <MacGalempsy> anyone have a link for hooking a dial potentiometer into the feedrate override, the pot read 0-24v output and has a range of 0-200%
[19:24:15] <jdh> got something with an analog input?
[19:24:56] <MacGalempsy> mesa 7i77
[19:25:59] <MacGalempsy> the manual mentions the card is capable of handleing a potentiometer, but I can only get it to read as TRUE/FALSE, not as a voltage
[19:26:49] <MacGalempsy> I will post the INI files.
[19:27:32] <cpresser> MacGalempsy: did you set the sserial-mode?
[19:29:40] <MacGalempsy> it has a 7i84 attached, so the settings for that are confusing
[19:30:23] <MacGalempsy> just got my linux box connected to net. I will post the key files and maybe someone would be kind enough to help me out
[19:37:57] <Mac-vmc> Here is a copy of the HAL file http://pastebin.com/DP2YEeAa
[19:38:19] <Mac-vmc> and INI http://pastebin.com/QQM0YVZD
[19:50:13] <JT-MOBILE> My swag is you need to configure the analog input
[19:50:39] <JT-MOBILE> But I don't have a manual on my phone
[19:52:21] <cpresser> MacGalempsy: see the second post here: http://www.linuxcnc.org/index.php/english/forum/39-pncconf/29046-5i25-7i76-software-encoder-for-mpg-on-input-pins
[19:52:30] <cpresser> it tells you how to change the mode
[19:52:48] <cpresser> the 7i77 manual will tell you which mode does support analog input
[19:52:51] <MacGalempsy> ok, was reading the hostmot2
[20:05:27] <MacGalempsy> does 5i25.0.7i77.0.0.input-opendrain look right?
[20:05:53] <pcw_home> no
[20:11:29] <pcw_home> If you want to know what hardware pins are available you can load linuxcnc and then in a terminal window type
[20:11:31] <pcw_home> halcmd show pin | grep 5i25
[20:11:32] <pcw_home> ( for pins ), or
[20:11:33] <MacGalempsy> ahhh here we go
[20:11:34] <pcw_home> halcmd show params | grep 5i25
[20:11:35] <pcw_home> ( for parameters )

[20:16:50] <zeeshan-mill> :(
[20:56:07] <Tom_itx> zeeshan-mill, check the .var file
[20:56:59] <PetefromTn_> evening folks
[20:57:44] <XXCoder> yo
[20:59:04] <PetefromTn_> damn I'm tired
[21:00:05] <PetefromTn_> did I miss anything interesting ;)
[21:05:01] <XXCoder> not really
[21:06:03] <Tom_itx> PetefromTn_ have you ever tried entering the G54 offsets directly to the memory addres defined by RS274?
[21:06:46] <Tom_itx> ie: G54 X is 5221
[21:06:58] <Tom_itx> Y is 5222 etc
[21:07:00] <PetefromTn_> I am not sure I understand your question
[21:07:06] <PetefromTn_> in MDI?
[21:07:10] <Tom_itx> memory map
[21:07:22] <Tom_itx> on some older machines you had to enter it that way
[21:07:30] <PetefromTn_> well since I don't know what you mean I would have to say NO LOL
[21:07:53] <PetefromTn_> oh you mean NOT on linuxCNC
[21:07:53] <Tom_itx> ^^ in order to set up the G54 55 etc work offsets
[21:07:57] <Tom_itx> yeah
[21:08:02] <Tom_itx> or anywhere for that matter
[21:08:19] <PetefromTn_> most of the machines I have run have been HAAS and they are quite similar to linuxCNC really
[21:08:38] <Tom_itx> we had one that was like that but i can't remember what control it was
[21:09:09] <PetefromTn_> even the original control had a similar setup to linuxCNC really which was Emerson Control Techniques
[21:09:57] <PetefromTn_> Tom_itx I gotta tell ya today I have had a BUNCH of orders for the rails I have been selling and I was running the now well proven program and I REALLY was wanting that damn toolchanger to work LOL
[21:10:32] <Tom_itx> it looks pretty well defined in the carousel comp in 2.7
[21:10:42] <Tom_itx> even a sim demo you can run to see it work
[21:10:46] <PetefromTn_> I would need to do something about the coolant nozzles tho because I do need to adjust for each cutter now
[21:11:07] <MacGalempsy> so I got this potentiometer in there and the counts and scale picked, but the AXIS visual control seems to be taking priority over the dial, but I cannot find how to cancel the onscreen feed-override
[21:11:13] <Tom_itx> our spindles had several shooting straight down to the tool area
[21:11:24] <Tom_itx> plus a few plastic ajustable ones
[21:11:31] <PetefromTn_> I have been looking into building some sort of manifold that has a few more nozzles on it with smaller orifices
[21:11:42] <MacGalempsy> anyone know which file I need to edit to do this? it is not in any of the standard HAL or PYVCP files in the configs folder
[21:11:50] <Tom_itx> a ring around the spindle might work
[21:11:51] <PetefromTn_> right now I have two one is a big one and the other slightly smaller...
[21:12:00] <Tom_itx> with plastic coming down from it
[21:12:12] <PetefromTn_> they work fine but when switching from a drill to an 1/8 endmill it is not happenin LOL
[21:12:21] <Tom_itx> that way it would follow the tools
[21:12:48] <PetefromTn_> I saw a guy build a ring like that with copper small diameter tube nozzles you could bend etc.
[21:13:17] <zeeshan-mill> Tom_itx, doesnt change
[21:13:19] <Tom_itx> the old new brittans i ran all used copper tube
[21:13:26] <zeeshan-mill> man these wood pieces smell good when youre machining them
[21:13:38] <Tom_itx> zeeshan, did you check the .var file itself?
[21:13:39] <zeeshan-mill> i see a mix of plastic and wood chips
[21:13:41] <zeeshan-mill> Tom_itx, yes
[21:13:51] <Tom_itx> acording to that page it should change
[21:13:53] <PetefromTn_> today was my youngest daughter's birthday
[21:14:12] <zeeshan-mill> how old pete?
[21:14:21] <zeeshan-mill> Tom_itx, maybe you cant change it through mdi?
[21:14:23] <PetefromTn_> so I machined parts this morning and then she wanted to have a bowling party so we went over there
[21:14:39] <PetefromTn_> then we all went to Olive Garden for dinner/birthday cake
[21:14:45] <Tom_itx> zeeshan, write a test file that calls a dummy sub that changes the offsets
[21:14:46] <PetefromTn_> she is 9
[21:15:08] <Tom_itx> 9 goin on 19?
[21:15:27] <PetefromTn_> not really but I know what you mean
[21:16:25] <PetefromTn_> we got her this cool liitle Remote Controlled Wall-E robot
[21:16:46] <PetefromTn_> I love when he says his name ;)
[21:17:29] <PetefromTn_> his eyes/lights even bend down like the movie and his hands move
[21:18:09] <os1r1s> PetefromTn_: I got one of those for my son. They are great
[21:18:10] <PetefromTn_> I was kinda hoping he could open his belly and put stuff inside to move it around so I could have it deliver my soda but it does not open :(
[21:18:20] <Contract_Pilot> Whoo.. Hoo... long day got home and have my path pilot disk.
[21:18:29] <PetefromTn_> oh cool
[21:18:36] <PetefromTn_> its a neat little robot huh
[21:18:50] <os1r1s> PetefromTn_: It is. Lots for fun for the kids to play with
[21:18:57] <os1r1s> We also have the eve, but its not as fun
[21:19:20] <PetefromTn_> and that is one of the few cartoon movies I can really enjoy
[21:19:21] <atom1> zeeshan, what gcode will READ the G54 offset values?
[21:19:37] <PetefromTn_> Contract_Pilot neato man let us know how you get along with it
[21:19:48] <Contract_Pilot> Making a backup! of disk Now!
[21:20:25] <PetefromTn_> have you seen the thread on CNCzone that discusses adapting it to other machines?
[21:20:34] <Contract_Pilot> Yep...
[21:20:56] <Contract_Pilot> Reason why my post to shwitch form mach to lcnc
[21:21:17] <Contract_Pilot> Now waiting on my mesa combo.
[21:21:17] <PetefromTn_> oh forget mach LOL
[21:21:54] <PetefromTn_> I must say that linuxCNC has been DEAD Reliable for me on the VMC so far.
[21:21:55] <furrywolf> what advantages does path pilot have?
[21:22:07] <PetefromTn_> it has a nicer interface
[21:22:15] <Contract_Pilot> Yea, spent to much time on mach.
[21:22:32] <bobo> Reasion #2 for a tool changer https://www.facebook.com/15179589950...64422/?fref=nf
[21:22:40] <Contract_Pilot> And the Conversational
[21:22:58] <furrywolf> does it do anything better, or is it just shinier?
[21:23:13] <PetefromTn_> well it does have the updated toolpath
[21:23:38] <PetefromTn_> if you search youtube for Tormach lathe you can see the new interface
[21:23:44] <atom1> ze
[21:23:44] <PetefromTn_> I must admit it is quite nice
[21:23:51] <atom1> zeeshan, try something...
[21:23:53] <atom1> mkay?
[21:24:03] <atom1> user variables
[21:24:04] <PetefromTn_> and I was very bummed when I found out we would not be getting it....
[21:28:19] <Contract_Pilot> BRB reboot winblows.
[21:31:00] <atom1> zeeshan, i think if you use gcode user variables you can do what you want and set the G54 offsets
[21:31:13] <atom1> i get an error using mdi as well in sim
[21:31:57] <SpeedEvil> http://www.ebay.co.uk/itm/Amadeal-Mini-Lathe-Brand-New-7x14-Machine-with-DRO-4-Chuck-Metal-Gears-/261740534866?hash=item3cf0f39c52
[21:32:03] * SpeedEvil idly wonders how shit this is.
[21:33:01] <SpeedEvil> hmm.
[21:33:07] <SpeedEvil> http://www.ebay.co.uk/itm/MyFord-Super-7-ML7-Lathe-Cabinet-More-/331658649399?hash=item4d38655f37 within 5 miles.
[21:33:51] <PetefromTn_> I would much prefer the second one ;)
[21:34:05] <SpeedEvil> yeah
[21:35:37] <atom1> zeeshan, i figured out the syntax for you
[21:36:16] <atom1> G10 L2 P1 X[#5221+incrementalvalue]
[21:36:25] <atom1> ie: G10 L2 P1 X[#5221+3]
[21:36:54] <os1r1s> Any idea where you can find a db25 panel mount extension?
[21:36:56] <atom1> you need to add to the memvar directly but access it using the G10 L2 function
[21:37:33] <atom1> you can test that in sim as well
[21:37:55] <PetefromTn_> what is zeeshan trying to do exactly?
[21:38:43] <Tom_itx> use the same fixture offset but increment it in gcode so it acts like G54 55 56 etc
[21:38:51] <Tom_itx> without changing the G54
[21:38:59] <Tom_itx> just change the X coord on the fly
[21:39:05] <Tom_itx> ^^ that will do it
[21:39:20] <Tom_itx> so he can run the same code in a sub on all his fixture
[21:39:45] <Tom_itx> put the x coord in the main file and run the program as a sub
[21:40:03] <Tom_itx> then increment it at the endsub in the main file
[21:40:22] <Tom_itx> loop however many times he has fixtures for
[21:40:26] <PetefromTn_> I usually just use the available offsets unless there is a LOT of parts then I just use CAM to do everything.
[21:40:45] <Tom_itx> he tried to use subs in his cam but it didn't work right
[21:40:57] <Tom_itx> this should work fine i think
[21:41:09] <Tom_itx> and he'll only need one part worth of gcode
[21:41:42] <Tom_itx> surface files get big pretty quick
[21:42:42] <Tom_itx> i repeated this in mdi and it incremented the G54 X offset by 3 each time: G10 L2 P1 X[#5221+3]
[21:43:27] <PetefromTn_> Tom_itx Hey man I was thinking about you today
[21:43:39] <PetefromTn_> I was out in the shop running parts
[21:43:58] <PetefromTn_> and since I have several different programs for different rail types now
[21:44:16] <PetefromTn_> I was like I GOTTA find a better way to setup for each one quicker
[21:44:41] <PetefromTn_> then I remembered your suggestion about using a tool as an X axis stop
[21:44:52] <PetefromTn_> so I tried it on my Steyr rail program
[21:44:56] <Tom_itx> oh hell ya...
[21:45:00] <PetefromTn_> I used my spot drill
[21:45:08] <Tom_itx> just use a dowel pin
[21:45:18] <Tom_itx> they're pretty accurate
[21:45:23] <PetefromTn_> and I programmed it to come down beside the stock
[21:45:39] <PetefromTn_> all of the rails I make are 1x2 material
[21:45:44] <PetefromTn_> so I center in Y
[21:45:48] <os1r1s> PetefromTn_: Pictures?
[21:45:51] <PetefromTn_> but the X changes
[21:46:02] <PetefromTn_> since they are all different lengths
[21:46:06] <Tom_itx> right
[21:46:08] <PetefromTn_> this way the program starts
[21:46:18] <PetefromTn_> I load tool6 which is the spot drill
[21:46:26] <PetefromTn_> it comes down aside the vise
[21:46:33] <Tom_itx> we used a high tool number so it was always the same one
[21:46:39] <Tom_itx> like 16 etc
[21:46:46] <PetefromTn_> and I take the stock and pop it atop the parallels
[21:46:49] <Tom_itx> usually the last tool in the carousel
[21:46:56] <PetefromTn_> and slide it over to the spot drill
[21:47:17] <PetefromTn_> then I just lock it down with the vise handle and beat it down with my rubber mallet
[21:47:25] <PetefromTn_> then I have an option stop
[21:47:34] <Tom_itx> right
[21:47:44] <Tom_itx> so you can finish tightening it
[21:47:50] <PetefromTn_> so I hit the pause button and the head comes up and asks for the next tool which is the facemill/flycutter
[21:48:09] <PetefromTn_> I did this with two of the six parts I make because that is what I was working on today
[21:48:17] <PetefromTn_> when I do the others I will make the same adjustment
[21:48:20] <PetefromTn_> VERY cool man
[21:48:28] <Tom_itx> time saver
[21:48:30] <PetefromTn_> MUCH faster than touching off each damn piece
[21:48:43] <PetefromTn_> if only there was an easy way to touch off the Y like that
[21:48:54] <PetefromTn_> I mean besides a quality tool probe LOL
[21:48:55] <Tom_itx> keep the back edge of the vise
[21:49:05] <Tom_itx> we used that
[21:49:32] <PetefromTn_> I work all my programs from the center of part/center of stock
[21:49:50] <PetefromTn_> os1r1s I do not have any pictures of this sorry man
[21:49:58] <Tom_itx> we used the back edge of the vise and the edge of the dowel as X0 Y0 in the cad
[21:50:13] <Tom_itx> whether the X was left or right didn't matter
[21:50:19] <Wolf_Mill> I set my cam use to use the back of the vice + side stop
[21:50:28] <Tom_itx> just set the cad up with the dowel stop where you want it
[21:51:10] <PetefromTn_> actually I just hand coded the dowel stop
[21:51:16] <PetefromTn_> it is dead simple really
[21:51:25] <Tom_itx> add it as a tool to your cad and it will be there
[21:51:30] <PetefromTn_> it sure as hell makes setup quicker tho
[21:51:38] <Tom_itx> and you can do it all in your cad from here on
[21:51:52] <PetefromTn_> well like I said it IS a tool
[21:52:01] <Tom_itx> not all parts are run that way but those that are sure saves time
[21:52:10] <PetefromTn_> it is my spot drill which has a mostly solid shank .3125
[21:52:27] <Tom_itx> right but if you use a dowel you can set your cad up with S0 zero spindle speed
[21:52:54] <PetefromTn_> I think I can do that anyway
[21:52:59] <Tom_itx> we used .500 dowel because it was easy to remember
[21:53:07] <PetefromTn_> besides this does not consume another holder
[21:53:20] <Tom_itx> yeah i suppose if you're limited on holders
[21:53:22] <Wolf_Mill> http://i.imgur.com/XmoaH9j.jpg sounds sorta like what I did here, had to do 2 halfs (3 programs each) but the 2nd half I used a drilled hole as my x,y 0
[21:53:56] <Tom_itx> we just kept a dowel in the carousel on every machine
[21:54:05] <Tom_itx> and knew where it was for each one
[21:54:36] <PetefromTn_> that's cool...this works great and since the spot drill is USUALLY my first tool for a lot of stuff it is even a step quicker
[21:54:47] <Tom_itx> yeah
[21:54:52] <PetefromTn_> Wolf_Mill nice
[21:55:18] <Tom_itx> one time you'll slam the block against it and tweak it possibly...
[21:55:23] <Wolf_Mill> what happens when you have 7.5" of X travel, but a 12.5" part
[21:55:45] <PetefromTn_> I would use the fixed jaw for the Y axis but honestly since I program everything from the center of the part/material I would have to change too much shit
[21:55:55] <Tom_itx> Wolf_Mill, same thing i told zeeshan, set it up diagonally and see if it will fit
[21:56:16] <Tom_itx> not sure that much would but it might
[21:56:28] <PetefromTn_> its a 5/16 solid spot drill in an ER32 holder....it's pretty stout LOL
[21:58:14] <PetefromTn_> I have been REALLY trying to optimize these programs lately as well
[21:58:28] <PetefromTn_> Speeding up what I can and getting rid of air cutting whenever possible
[21:58:31] <Tom_itx> yeah ones we ran alot we edited out all the air cuts
[21:59:15] <Tom_itx> and tried to opimize where the tool was and cut everything there first
[21:59:22] <PetefromTn_> I gotta machine a bunch of steel parts here soon if the race shop guys come thru with the cash LOL
[21:59:43] <Tom_itx> it'll screw up your coolant
[21:59:59] <PetefromTn_> will probably order a bunch of YG1's for that
[22:00:02] <PetefromTn_> huh?
[22:00:10] <Tom_itx> rust etc
[22:00:17] <Tom_itx> if you let it sit much
[22:00:31] <PetefromTn_> I cut steel a lot actually, cast iron too...so far no problems
[22:00:48] <PetefromTn_> but this will be a good bit of cutting steel 1/2 inch plate
[22:00:55] <Tom_itx> the old brittans i ran use oil from 55 gal barrels
[22:01:02] <PetefromTn_> well a good bit for my shop anyway
[22:01:28] <Tom_itx> i'd usually add half a barrel at a time when it got low
[22:01:54] <furrywolf> I was going to work on generators today, but I ended up just improving my workspace (I had them sitting on pallets... now they're sitting on plywood on pallets) and giving one of them a coat of wax.
[22:02:25] <Tom_itx> dammit zeeshan! where did you go...
[22:03:03] <PetefromTn_> he doesn't have time for our bullshit anymore ;)
[22:03:21] <Tom_itx> then he's doing it the hard way..
[22:03:55] <Jymmm> Tom_itx: zeeshan-mill is in the.... <cue spooky music> THE OUTER LIMITS
[22:04:41] <Tom_itx> PetefromTn_, the drill doesn't get in the way like a side stop would either
[22:05:03] <Tom_itx> or get bumped and changed...
[22:05:26] <PetefromTn_> yeah man exactly
[22:05:36] <PetefromTn_> that is one of the things I was dealing with
[22:05:49] <Tom_itx> can't mill that end unless you moved it
[22:06:04] <PetefromTn_> I usually setup 123 blocks with a skinny parallel using strap clamps for a temporary stop
[22:06:10] <PetefromTn_> but when I use that flycutter
[22:06:20] <PetefromTn_> it cuts a 4.5" swath
[22:06:38] <PetefromTn_> and I have to be really carful I don't smack that strap clamp
[22:06:46] <PetefromTn_> or bad shit will happen
[22:06:55] <PetefromTn_> this way there IS no stop LOL
[22:07:04] <Tom_itx> i poked a hole in the rear of the enclosure once that way
[22:07:08] <PetefromTn_> I must say it was really nice
[22:08:10] <PetefromTn_> I will be doing that from now on I think.
[22:08:30] <PetefromTn_> Even if it just saves me from having to touch off just the X that is still a time saver
[22:08:42] <PetefromTn_> ya know what would REALLY help me tho
[22:08:59] <PetefromTn_> when I machine these parts I cut the part down to the depth of the part atop the vise
[22:09:12] <PetefromTn_> leaving the flashing that I was holding on to below that
[22:09:31] <PetefromTn_> for instance I use 1" material for the Steyr rails and the cut only goes .88 deep
[22:09:43] <PetefromTn_> so that leaves that lip on the bottom
[22:10:00] <PetefromTn_> then I turn it over and the program requires me to face off that flashing
[22:10:09] <PetefromTn_> then I can touch off the actual part body
[22:10:19] <Tom_itx> you face it off or profile it ?
[22:10:25] <PetefromTn_> if I am making more than one it is no big deal because I only have to do it once
[22:10:31] <PetefromTn_> I face it off
[22:10:37] <PetefromTn_> down to the part
[22:10:53] <PetefromTn_> then it is mostly champfering and pocketing to mirror the first side
[22:11:02] <PetefromTn_> but the problem is
[22:11:20] <PetefromTn_> that I cannot simply touch off the flashing because it is not accurate enough
[22:11:30] <PetefromTn_> and the part exists inside the edge of that flashing
[22:11:38] <PetefromTn_> so I typically use a stop
[22:11:45] <PetefromTn_> and touch off the edge of the stop
[22:11:51] <PetefromTn_> slide the part to the stop
[22:12:07] <PetefromTn_> and program the offset distance to the center of the part
[22:12:16] <PetefromTn_> to get to G54 X0Y0
[22:12:18] <Tom_itx> ok, well you know how much you're taking off when you face the first side so remove that when you program the bottom side and you don't need to touch off at all. add a 'DOWEL PIN' tool change / op stop to flip the part and locate it then finish facing P2
[22:12:36] <Tom_itx> you already know what you removed
[22:12:40] <Tom_itx> use that to your advantage
[22:13:18] <PetefromTn_> ?
[22:13:34] <Tom_itx> you face off and profile P1 right?
[22:13:47] <Tom_itx> position 1
[22:13:52] <PetefromTn_> the face on the p1 is just a light skim to get to smooth metal
[22:14:02] <Tom_itx> then you profile it?
[22:14:09] <Tom_itx> and flip it over?
[22:14:11] <PetefromTn_> then I profile it to depth of the part
[22:14:19] <PetefromTn_> yes
[22:14:25] <Tom_itx> so you know how much you remove
[22:14:40] <PetefromTn_> you mean the flashing?
[22:14:45] <Tom_itx> for P2 use that as your Y0 reference
[22:14:47] <Tom_itx> no
[22:14:52] <Tom_itx> the flashing is what is left
[22:15:00] <Tom_itx> if i understand you right
[22:15:10] <PetefromTn_> Oh you are talking about Y
[22:15:20] <PetefromTn_> I thought you were talking about Z
[22:15:31] <Tom_itx> X would be the same because the flashing is still there
[22:15:40] <Tom_itx> you also know what you took off for X
[22:15:41] <Tom_itx> Z
[22:15:43] <Tom_itx> sry
[22:15:45] <enleth> I'm starting to suspect why exactly was my bridgeport put out of use. The control has some intermittent problems with spindle interlock safety checks that prove to be extremely hard to track down.
[22:15:52] <PetefromTn_> yeah but I do not finish cut my material it is just rough sawm
[22:15:55] <PetefromTn_> sawn
[22:16:07] <Tom_itx> finish one side before you start
[22:16:17] <PetefromTn_> so I cannot rely on the edges
[22:16:27] <Tom_itx> ^^ then you could
[22:16:33] <Tom_itx> or 2 edges
[22:16:54] <PetefromTn_> yeah but that is ANOTHER Step
[22:17:01] <Tom_itx> we usually started with known block sizes
[22:17:11] <PetefromTn_> yeah I do too
[22:17:15] <PetefromTn_> but I just bandsaw it
[22:17:22] <PetefromTn_> so it is not really precise
[22:17:23] <Tom_itx> that's unknown :D
[22:17:33] <PetefromTn_> yeah
[22:17:56] <Tom_itx> doesn't take long once you have the shell mill to depth
[22:18:05] <Tom_itx> do them all at once
[22:18:36] <PetefromTn_> yeah I don't think that is the right method for me for this instance
[22:18:42] <Tom_itx> over all it ends up being faster
[22:19:56] <PetefromTn_> right now I setup the stop for the second side, pickup the edge of the stop, slide the part to it, and work off the fixed jaw for the Y offset, adjust and I am on position
[22:20:43] <Tom_itx> that sounds about right
[22:21:03] <Tom_itx> you're worried about Z?
[22:21:11] <PetefromTn_> yeah but if there was a way to use that traveling stop it would be cool
[22:21:22] <Tom_itx> you can
[22:21:23] <PetefromTn_> no not really Z is from top of stock always for me
[22:21:36] <PetefromTn_> how?
[22:21:44] <Tom_itx> just remember what you remove and put the center drill where you want it in the cad cam
[22:21:48] <Tom_itx> with an op stop after it
[22:22:14] <Tom_itx> use the 'dowel' for all of it
[22:22:19] <PetefromTn_> I could possibly use the traveling stop with say a dowel pin
[22:22:33] <PetefromTn_> to reach under the flashing
[22:22:41] <PetefromTn_> and adjust the part to it
[22:22:56] <Tom_itx> if you mill the end flat you don't need to reach under the flashing
[22:23:13] <Tom_itx> you know how much material you removed in P1 and adjust the dowel for that
[22:23:45] <PetefromTn_> yup but trying to avoid that additional step ;)
[22:23:48] <Tom_itx> unless i'm not following
[22:24:00] <PetefromTn_> no I think you are following just fine
[22:24:15] <PetefromTn_> it overhangs something like a quarter inch or so
[22:24:17] <Tom_itx> oh yeah... no ATC :)
[22:24:28] <Tom_itx> that slows things down quite a bit
[22:24:38] <PetefromTn_> har de har harr
[22:24:57] <PetefromTn_> I am pretty fast with the toolchange manually ;)
[22:25:04] <Tom_itx> we ran a BOSS5 quite a while like that
[22:25:19] <Contract_Pilot> backup burn boots but requires mesa card as i thought. http://www.stevenrhine.com/wp-content/uploads/2015/09/Path-Pilot-Install-Mesa-Card-Required.jpg
[22:26:25] <Tom_itx> PetefromTn_, so you're reaching under the undercut to set the X axis offset for P2?
[22:26:49] <Contract_Pilot> So need mesa card darn it.
[22:26:58] <PetefromTn_> yeah
[22:27:05] <Contract_Pilot> they are out 4 weeks for combo.
[22:27:09] <os1r1s> Contract_Pilot: Is it open source?
[22:27:15] <Tom_itx> and it's about 1/4" thick?
[22:27:20] <os1r1s> path pilot?
[22:27:27] <Tom_itx> i have a crazy idea...
[22:27:32] <PetefromTn_> something like that yeah
[22:27:42] <PetefromTn_> I know fix the toolchanger
[22:28:02] <Tom_itx> get a step drill for the center drill and let the shank hang out a bit and use that but lower it so the shank clears the undercut
[22:28:04] <Contract_Pilot> Should be.
[22:28:04] <Contract_Pilot> it is linux cnc
[22:28:06] <Contract_Pilot> but a Path Pilot GUI and Features
[22:28:23] <Tom_itx> make sure the shank is 1/4" smaller than the tool diameter
[22:28:41] <Tom_itx> and use the tool diameter still to set the X axis
[22:29:06] <Tom_itx> like a .500 shank 1" drill
[22:29:07] <Wolf_Mill> some radius bits have that kinda step
[22:29:11] <PetefromTn_> actually that is not a bad idea
[22:29:15] <Tom_itx> :)
[22:29:37] <PetefromTn_> I could machine a round boss that screws onto the top of the shaft near the toolholder
[22:29:56] <PetefromTn_> and measure the radius to get my offset
[22:29:58] <Tom_itx> whatever.. you get the idea
[22:30:00] <PetefromTn_> Hm
[22:30:37] <PetefromTn_> it sure would be sweet not to have to touch off with my Starrett edge finder each time I go to setup one of these thigns
[22:30:41] <PetefromTn_> things
[22:30:54] <Tom_itx> it's a cnc... make it work for you
[22:31:01] <PetefromTn_> Oh it has been ;)
[22:31:08] <PetefromTn_> sold four yesterday alone
[22:31:21] <Tom_itx> cool
[22:31:34] <Wolf_Mill> other option might be to make a stop that bolts to the vise side
[22:31:36] <PetefromTn_> apparently the race shop guys sold two more rotor machining sets too they just told me
[22:32:10] <PetefromTn_> Wolf_Mill yeah I agree and that is what I usually do here
[22:32:24] <PetefromTn_> but I make several different styles of rails
[22:33:00] <PetefromTn_> and each on requires a different zero since even tho the X0Y0 is in the center of them all they are all different lengths and widths
[22:33:26] <PetefromTn_> with the floating stop pin like Tom recommended I can just load the program and hit the stop when it comes down into position.
[22:33:55] <PetefromTn_> I am gonna have to think about this setup a bit more here
[22:34:03] <PetefromTn_> but I like this idea
[22:38:04] <Tom_itx> Wolf_Mill, we've done that before too but it gets in the way sometimes
[22:38:50] <PetefromTn_> https://greenville.craigslist.org/tls/5165796279.html this looks like a sweet machine
[22:38:55] <Wolf_Mill> once you are clamped in the vice, I swing the stop out of th way
[22:39:37] <PetefromTn_> these parts are all much wider than the vise
[22:39:46] <PetefromTn_> the narrowest is like 9.5 inches
[22:40:08] <Wolf_Mill> which is why you are zero from center, right
[22:40:31] * Wolf_Mill is still learning...
[22:41:02] <PetefromTn_> well to be honest I zero from center because that is how we always did it in the job shops I worked in. A lot of the machines had probing so it is simpler that way
[22:41:11] <Wolf_Mill> ahh
[22:41:19] <Tom_itx> we seldom did that :)
[22:41:33] <PetefromTn_> plus when you touch off each side of the part and find the middle you basically cut any error in half
[22:42:43] <PetefromTn_> did you guys have probing?
[22:42:55] <Tom_itx> we had wireless probes
[22:42:59] <PetefromTn_> huh
[22:43:03] <PetefromTn_> that is what we had
[22:43:21] <PetefromTn_> you only had to bring the probe down near the center of the part and start the probe routing
[22:43:22] * furrywolf has no probes (of the cnc variety)
[22:43:38] <PetefromTn_> it found the center in X and Y and touched off Z all automatically
[22:43:44] <PetefromTn_> slick as snot
[22:45:02] <Tom_itx> we didn't use it much for that
[22:45:16] <furrywolf> I have meter probes, high voltage probes, oscilloscope probes, g-spot probes, etc... but no cnc probes. I wouldn't mind one, though!
[22:45:30] <Tom_itx> the one that got use the most was on those Ti trailing links for landing gear to probe some critical holes
[22:45:48] <PetefromTn_> wow man we used it on EVERYTHING
[22:45:56] <XXCoder> wonder if theres cheap probes lol
[22:46:02] <PetefromTn_> there is
[22:46:09] <Tom_itx> you can have good or you can have cheap
[22:46:16] <PetefromTn_> or fast
[22:47:21] <Wolf_Mill> I have learned fast that good measuring tools cost $$$
[22:47:42] <PetefromTn_> yeah that is what we did on almost everthing because it was mostly automatic. just clamp the part down, pound it down onto the parallels, bring probe near center by eyeballmic and set some general rough parameters and the machine does the rest
[22:48:22] <PetefromTn_> I would LOVE to have that wireless probing for my VMC...maybe someday
[22:48:45] <PetefromTn_> but honestly even that would not really help me with this issue of the flashing
[22:48:55] <PetefromTn_> still would have to face it off before the probing
[22:49:24] <Wolf_Mill> I think I have now spent more $$ on mic/calipers and di then I paid for my two mini machines here lol
[22:49:49] <PetefromTn_> thats a start :D
[22:50:40] <furrywolf> I have harbor freight calipers. they're cheap. heh.
[22:50:47] <furrywolf> (in more than one meaning of the word!)
[22:51:01] <PetefromTn_> I have a few of those
[22:51:02] <XXCoder> I have my aliexpress caliper. its good enough for home use
[22:51:03] <Wolf_Mill> I have 3 of them
[22:51:11] <Tom_itx> PetefromTn_, the step dowel would fix your problem with the flashing
[22:51:17] <XXCoder> work I has nice mitroyshi something caliper and mm
[22:51:26] <PetefromTn_> honestly the biggest difference between those and my nice Mitutoyos is the hardened jaws and coolant proofness
[22:51:32] <Wolf_Mill> one of them is soon to get cut up and mounted on the cross slide of the lathe
[22:51:36] <Contract_Pilot> wolf
[22:51:47] <Contract_Pilot> or wolfe's
[22:51:53] <furrywolf> which? :P
[22:52:00] <XXCoder> my chinese special one I wouldnt trust precision past .003
[22:52:38] <Contract_Pilot> got my disk 10hours at gun show and another 9 in the morning then will iso for ya!
[22:52:38] <Tom_itx> PetefromTn_, if zeeshan shows up tell him i fixed his fixture offsets problem
[22:52:47] <PetefromTn_> generally speaking calipers are only good to .0005 or so so basically even the cheap chinese ones are decent in that regard
[22:52:55] <Contract_Pilot> Mon/tuesday!
[22:53:14] <XXCoder> PetefromTn_: yeah but for work its just not precise enough. it varies across .003
[22:53:22] <XXCoder> +-.0015
[22:53:26] <PetefromTn_> Tom_itx I will but I am about to sign off here too LOL
[22:53:40] <Wolf_Mill> I grabed a mitutoyo mic and caliper plus a interapid di off facebook group last week, should be here monday (unless it was a scam lol)
[22:53:51] <PetefromTn_> nice
[22:53:57] <PetefromTn_> interapid is the cats ass
[22:54:15] <PetefromTn_> I have a brown and sharp but I want an angled interapid
[22:54:24] <Wolf_Mill> $318 for all 3... dont think I did too bad
[22:54:36] <PetefromTn_> shit no the interapid alone is that much
[22:54:46] <XXCoder> PetefromTn_: though it once glitched and it was at umm 5.3 inches at zero position
[22:54:56] <XXCoder> just didnt see how that could happen lol
[22:55:05] <Wolf_Mill> magnets
[22:55:20] <XXCoder> chinese special lol
[22:55:20] <Wolf_Mill> or metal things, just right on them will cause odd stiff
[22:55:31] <PetefromTn_> easy just hit zero accidentally
[22:55:31] <Wolf_Mill> or if the batt is low
[22:55:32] <furrywolf> my chinese ones start glitching more as the battery goes dead, eventually becoming completely random
[22:55:33] <Contract_Pilot> what FB group Wolf?
[22:55:56] <XXCoder> furrywolf: Wolf_Mill yeah battery is most likely. I hgave to zero it pretty often
[22:56:03] <furrywolf> they eat SR44 batteries every few months.
[22:56:26] <Wolf_Mill> Used Machinist tools For Sale < group
[22:56:32] <XXCoder> how fast do mitutyo ones use batteries?
[22:56:36] <Contract_Pilot> Batterys vs learning how to read a good scale!
[22:57:15] <Contract_Pilot> I am a member!
[22:57:40] <furrywolf> be sure to get SR44s. generic alkaline ones seem to last about a week. :)
[22:57:57] <PetefromTn_> I am in that group also
[22:58:46] <furrywolf> dunno. send me a mitutoyo one and I'll let you know how it works out. :P
[22:58:48] <Contract_Pilot> Analog all the way!
[22:59:57] <Wolf_Mill> my one HF calipers used the same battery for 4 years
[23:00:25] <XXCoder> mines at 6 months and still going
[23:00:31] <Wolf_Mill> http://i.imgur.com/0icCblR.jpg
[23:01:06] <Contract_Pilot> kid next door runs a machine cannot read a dial but supplies me with unlimited CNMG 432 inserts so i showed him how!
[23:01:35] <furrywolf> lol
[23:01:36] <XXCoder> Wolf_Mill: lol bit buly and defnitely not coolant proof
[23:01:41] <XXCoder> *bulky
[23:01:51] <Wolf_Mill> I learned how to read a mic 3 days ago
[23:02:03] <XXCoder> still figuring mic out
[23:02:19] <furrywolf> I can't remember when I learned to read dial or vernier... too many years ago.
[23:02:59] <Wolf_Mill> I learned the dial a long time ago, dad taught me when reloading
[23:03:16] <Tom_itx> i don't really care for my mic that has the vernier scale on the side for tenths
[23:04:01] <Wolf_Mill> my mic is kinda old http://i.imgur.com/GRfkcl7.jpg ...
[23:04:43] <zeeshan-mill> thank you TOM!!
[23:04:44] <Tom_itx> i have one like that as well
[23:04:46] <zeeshan-mill> G10 L2 P1 X[#5221+incrementalvalue]
[23:04:47] <zeeshan-mill> will try this
[23:04:51] <Tom_itx> it works
[23:05:21] <zeeshan-mill> that i guess
[23:05:24] <zeeshan-mill> wont change the variable value
[23:05:27] <zeeshan-mill> itll just offset
[23:05:35] <Tom_itx> it changes the variable
[23:05:38] <Tom_itx> i think
[23:05:41] <furrywolf> I know how to do a lot of things I don't remember learning. having a bad memory sucks.
[23:05:43] <Tom_itx> it's supposed to
[23:06:14] <Tom_itx> i couldn't verify that because i was using a sim
[23:06:50] <zeeshan-mill> gonna aply it manually to the program
[23:07:37] <Tom_itx> no subroutine?
[23:08:12] <PetefromTn_> GN8
[23:08:16] <zeeshan-mill> to the sub routine
[23:08:17] <zeeshan-mill> nite pete
[23:16:41] <furrywolf> "A sophisticated software algorithm on certain Volkswagen vehicles detects when the car is undergoing official emissions testing, and turns full emissions controls on only during the test." LOL
[23:16:58] <XXCoder> indeed
[23:17:43] <Wolf_Mill> thats why the fuel milage is so good on them
[23:19:37] <zeeshan-mill> tom doesnt work
[23:19:38] <zeeshan-mill> :{
[23:19:49] <zeeshan-mill> N35 G10 L2 P1 X[#5221+2.625]
[23:19:49] <zeeshan-mill> N40 o0001 call
[23:19:54] <Tom_itx> does so!
[23:20:36] <zeeshan-mill> did it shift in axis for u?
[23:20:43] <Tom_itx> it did in the sim
[23:21:00] <Tom_itx> it added the value to the X G54 offset
[23:21:15] <zeeshan-mill> do you need to call g54
[23:21:15] <zeeshan-mill> again after the offset shift
[23:21:23] <Tom_itx> probably
[23:21:37] <Tom_itx> it needs to re read it i would imagine
[23:22:06] <furrywolf> bbl, wolfy bedtime
[23:22:29] <zeeshan-mill> doesnt do anything
[23:22:29] <zeeshan-mill> ;[
[23:22:33] <Wolf_Mill> seems to work here
[23:23:48] <Tom_itx> you could try storing the 2.625 in a var and adding it
[23:23:57] <Tom_itx> like: #31 = 2.625
[23:24:12] <zeeshan-mill> hm when i do it in mdi
[23:24:13] <zeeshan-mill> it works..
[23:24:19] <zeeshan-mill> but when i do it in my gcode it doesnt
[23:24:22] <zeeshan-mill> interesting!
[23:24:23] <Tom_itx> then G10 L2 X[#5221 + #31]
[23:24:55] <Tom_itx> or something like that
[23:25:10] <Tom_itx> gcode user vars start at #31
[23:26:03] <zeeshan-mill> it works in mdi
[23:26:15] <Tom_itx> i haven't used G10 much so i can't tell you the particulars about it
[23:26:29] <Wolf_Mill> hmm, works odd in mdi
[23:26:51] <Tom_itx> it _should_ work
[23:26:53] <zeeshan-mill> Wolf_, its backwards :D
[23:27:01] <Tom_itx> yeah
[23:27:04] <Tom_itx> i noticed that too
[23:27:13] <Tom_itx> add a value and it adds to the negative offset
[23:27:43] <zeeshan-mill> yes
[23:27:44] <zeeshan-mill> lol
[23:28:04] <zeeshan-mill> its right though
[23:28:06] <zeeshan-mill> it should work like that
[23:28:27] <zeeshan-mill> like if youre at zero
[23:28:28] <Contract_Pilot> Ahhh bed time! another 10 hours at gun show made enough to secure mesa combo unless i spend it!
[23:28:32] <zeeshan-mill> and you wanna shift to the right by 2"
[23:28:35] <Tom_itx> yes
[23:28:45] <zeeshan-mill> then the original 0 will be at -2
[23:28:46] <zeeshan-mill> from yo
[23:28:48] <zeeshan-mill> you
[23:28:51] <zeeshan-mill> so its right
[23:28:57] <Contract_Pilot> then pathe pilot config.
[23:29:14] <Contract_Pilot> Unless somone can bypass.
[23:29:55] <Tom_itx> zeeshan, i may try it on my mill tomorrow just to see if it changes the .var file variable
[23:30:04] <Tom_itx> it's supposed to i think
[23:30:46] <Tom_itx> look in the ini file directory for the .var file and see
[23:30:50] <Contract_Pilot> andypugh may figure a way to bypass.
[23:30:52] <zeeshan-mill> it will
[23:30:58] <zeeshan-mill> it changes
[23:31:01] <zeeshan-mill> my problem is with
[23:31:04] <zeeshan-mill> g90 / g91
[23:31:06] <Tom_itx> so it's gonna work for you?
[23:31:13] <zeeshan-mill> yes
[23:31:17] <Tom_itx> good
[23:31:18] <zeeshan-mill> but i need to figure out wtf is going on with this g91
[23:31:44] <Tom_itx> i use G90 most of the time
[23:32:00] <Tom_itx> that's offset from G54 zero i believe
[23:32:00] <Wolf_Mill> here is the odd part, did +50 from touch off at 0, shows g54 at 50, then did +10, show 11.969?
[23:32:13] <Tom_itx> G91 is incremental from the last point
[23:32:18] <Tom_itx> unless i'm mistaken
[23:33:21] <zeeshan-mill> ive had it for milling for tonight
[23:33:23] <zeeshan-mill> going upstairs :P
[23:33:27] <Tom_itx> hah
[23:33:30] <zeeshan-mill> will look at code
[23:33:36] <Tom_itx> set it up for G90
[23:34:03] <Tom_itx> gnite
[23:37:49] <Tom_itx> zeeshan, i don't use G91 much
[23:51:31] <renesis> g91 is awesome for looped code
[23:52:47] <renesis> i still work in g90 and then switch in and out of g91 in the sub routines, strictly in g91 hurts
[23:52:54] <zeeshan> Wolf_Mill: you there?
[23:57:44] <Wolf_Mill> yo
