#linuxcnc | Logs for 2017-02-01

[00:13:02] <Gene_work> Im placing an order with aliexpress, any add-on suggestions?
[01:03:26] <archivist> Wolf_, that set looks much nicer than my "workshop" grade
[01:03:44] <Wolf_> =)
[01:06:12] <archivist> but as for cal, when I compared 4 items, I could detect the difference and but dunno which is right
[01:06:25] <Wolf_> lol
[01:06:48] <jesseg> are they thickness gauges?
[01:07:07] <Wolf_> http://i.imgur.com/GCEHgzN.jpg < short set, http://i.imgur.com/BGKFSzY.jpg and the “full set”
[01:07:21] <archivist> table at the bottom http://www.archivist.info/cnc/bench_micrometer/
[01:07:57] <jesseg> wow slow server?
[01:08:22] <Wolf_> jesseg: gage blocks/ jo block

[01:10:57] <archivist> and balls http://www.collection.archivist.info/archive/DJCPD/PD/2013/2013_10_13_comparator/IMG_1679.JPG
[01:14:48] <jesseg> sweet
[01:15:43] <jesseg> I'm thinking of getting one of these before tariffs hit: http://www.ebay.com/itm/291862820013
[01:19:06] <Wolf_> I’m thinking about asking the local motor repair shop what they do with VFDs they pull
[01:20:29] <roycroft> the huan yang vfds are decent for imported ones
[01:20:46] <archivist> last one I bought was second hand off ebay, a european maker
[01:20:51] <roycroft> if you need to use the braking resistor feature, though, be sure it has the circuitry for that
[01:20:54] <roycroft> a lot of them don't
[01:21:09] <roycroft> there are also a lot of counterfeit huan yangs

[02:20:40] <Deejay> moin
[05:18:24] <Mac-phone> morning
[05:18:41] <XXCoder> hey maconish
[05:18:56] <Mac-phone> whats going on?
[05:19:05] <XXCoder> you entered
[05:19:48] <Mac-phone> woke up early today.
[05:19:59] <Mac-phone> with a runny nose :(
[05:20:26] <Mac-phone> what shift do you work?
[05:20:32] <archivist> graveyard
[05:20:40] <XXCoder> swing. techinically.
[05:21:05] <Mac-phone> is that what some call 2nd?
[05:21:36] <Mac-phone> is it still a
[05:21:43] <XXCoder> yeah
[05:21:50] <XXCoder> my work place has 3 shifts
[05:21:53] <Mac-phone> am archivist?
[05:22:03] <XXCoder> 1st 2nd and third which is on weekend and are 12 hour days
[05:22:22] <archivist> is actually AM today
[05:22:47] <Mac-phone> then good morning to you :)
[05:23:26] <archivist> it should be, waiting for a delivery
[05:23:32] <Mac-phone> had a boss once who said,"you can work a half day whenever you want...jist pick your 12hr shift:
[05:23:43] <Mac-phone> whats coming in?
[05:23:52] <archivist> some manuals
[05:24:05] <archivist> no idea how many :)
[05:24:22] <archivist> a few to a panic load
[05:24:36] <jthornton> morning
[05:24:40] <Mac-phone> lol. pallet delivery?
[05:24:56] <Mac-phone> gm JT
[05:25:06] <archivist> no car from someone I have known for years
[05:25:31] <Mac-phone> cool. get the beers ready
[05:25:59] <archivist> we do the occasional swap, he is collecting a couple of bits of Tektronix
[05:26:18] <archivist> I has no beer!
[05:27:05] <jthornton> elderberry is clearing nicely
[05:27:07] <XXCoder> beer, linuxcnc room stat!!
[05:28:14] <Mac-phone> none here either. my ny res is no drinky this year...
[05:28:21] <archivist> !beer me
[05:29:05] * jthornton drinks one beer a day at 5
[05:29:26] * XXCoder drinks beer per infinity days
[05:31:17] <Mac-phone> linuxcnc is my only vice now.
[05:31:52] <Mac-phone> my name is mac and ive been a user for 4 years...
[05:32:30] <jthornton> lol
[05:32:49] <XXCoder> heh
[05:34:10] <archivist> I am about up to 10 years
[05:35:06] <archivist> actually just 9 but was lurking in here a while first
[05:35:15] <Mac-phone> the channel topic should be welcome to therapy
[05:35:39] <Mac-phone> http://www.ebay.com/itm/360876720925
[05:36:14] <Mac-phone> thought this was a decent price for a barebones cnc
[05:37:37] <XXCoder> wild pacman found! https://i.chzbgr.com/full/4052083968/h8CD90C49/
[05:39:13] <jthornton> not much there for 2.8k
[05:42:41] <Mac-phone> no? no electronics? but the frame box and ballscrews seemed fair.
[05:42:53] <Mac-phone> i meant no elec.
[05:43:25] <jthornton> nothing there but the frame and ball screws and the oiling system
[05:46:42] <XXCoder> little too bare I would think
[05:48:34] <jthornton> hmm it's up in Rolla I wonder if it is some failed collage student project
[05:49:19] <jthornton> nope they strip machines and sell all the parts one at a time
[05:49:35] <Mac-phone> yeah
[05:50:06] <Mac-phone> even some whole panels had the mpg removed
[05:50:49] <Mac-phone> im sure local bargaining is possible
[05:51:23] <XXCoder> just remember that seemly decent maching tormach is just 10k
[06:00:34] * jthornton learns PyQt5 this morning
[06:02:08] <XXCoder> yeah? for what? :)
[06:03:19] <jthornton> I did a gui for the latency histogram yesterday might start a new gui for LinuxCNC with it
[06:03:56] <malcom2073> Do it in Qt/c++ :-D
[06:04:16] <jthornton> I don't know C++ :(
[06:04:26] <malcom2073> I used Qt to learn c++
[06:04:28] <XXCoder> c++ heh its a mess of library on c
[06:04:54] <malcom2073> It makes it easier to shoot yourself in the foot for sure
[06:05:00] <XXCoder> yeah
[06:05:00] <jthornton> I tried Qt C++ a few times
[06:05:04] <malcom2073> Though, it's pretty damn easy in c
[06:05:04] <malcom2073> heh
[06:05:49] <XXCoder> if(x = 1){callShootFoot();}
[06:06:27] <malcom2073> == :-P
[06:06:31] <XXCoder> nah
[06:06:41] <XXCoder> I delbrately used a bug
[06:18:04] <Mac-phone> mmmm coffee
[06:34:00] <Mac-phone> anyone got a link and opinion on making an axis.comp file? does it increase accuracy w ballscrews does it effect performance?
[06:59:10] <jthornton> the description is in the AXIS section of the INI Configuration chapter
[07:00:25] <MacGalempsy> i see that part, but wanting to know how to measure and generate the actual table
[07:02:15] <jthornton> very long travel dial indicator?
[07:02:50] <MacGalempsy> ok. so it is an actual measurement, not something that LCNC can manually produce
[07:03:27] <jthornton> it has no idea where the axis is without feedback
[07:07:49] <gregcnc> just install axis scales
[08:20:16] <jensor> What is the command to terminate linuxcnc?
[08:21:27] <jymmm> kill [pid]
[08:23:09] <jensor> Didn't work. I get a statement saying linuxcnc is still running
[08:23:36] <jensor> Option y/n to restart
[08:23:49] <jensor> Y doesn't work
[08:24:04] <jymmm> sudo kill [pid]
[08:24:14] <jensor> y doesn't work.
[08:24:58] <jensor> Yes it does - I used wrong case.
[08:26:28] <JT-Shop> halrun -U
[08:43:17] <nubcake> hi
[08:56:26] <nubcake> After configuring/flashing marlin1.1.0-RC8 onto my prusa i3 pro B (GT2560 with auto bed leveling enabled) the homing/leveling itself works fine, but right after the G28 G29 move, 00when it's supposed to start printing, Z is on +10mm, seems to start a very rapid move to lower Z, sounds like it's locking the threaded rod, after 1 second, it starts printing with Z 10mm in the air. What am i
[08:56:26] <nubcake> missing, any ideas/suggestions? #reprap didn't reply yet :/
[08:56:53] <archivist> you are missing linuxcnc
[08:57:55] <CaptHindsight> working firmware
[08:58:46] <nubcake> i bet it's just one setting i missed, but i can't seem to find it..
[08:59:03] <MacGalempsy> alright...got my new panel done.https://flic.kr/p/RyafGe some of the buttons will disappear after the tool changer is set up
[09:00:02] <JT-Shop> nubcake: might be a setting in your slicer
[09:00:47] <nubcake> JT-Shop, i didn't change anything there, just uploaded a new firmware to the GT2560
[09:00:59] <nubcake> but it seems to me like i missed one parameter
[09:01:15] <CaptHindsight> it's a set of patched kludges built on top of a library written as an example of what might have been written upside down in a mirror
[09:04:15] <jymmm> CaptHindsight: FYI, I found out the (newest) $89 HF Welder now has knurled feed rollers where the older generation (which is what I borrowed from the neighbor) does not.
[09:05:15] <MacGalempsy> jymmm: you going to retrofit his?
[09:06:51] <jymmm> MacGalempsy: Nah, I had to buy a spool to replace what I used, very bad feeding mech and I did some shitty welds with it because I couldn't get a puddle going due to it's intermittent feed - splatter city.
[09:07:17] <CaptHindsight> looks like they have learned that those criss crossy things are there for a reason
[09:08:19] <jymmm> CaptHindsight: That, and not to have a LIVE gun when NOT pulling the trigger =)
[09:10:53] <CaptHindsight> nah, it keeps the excitement level of welding up, like handing someone a circular saw while it's still running
[09:12:15] <CaptHindsight> like Marlin, you never know what it's going to do
[09:12:17] <jymmm> heh
[09:16:57] <roycroft> can you hook up a tank of shield gas to that hf machine?
[09:17:07] <CaptHindsight> there is a ball of fire in the sky today, the grey is gone!
[09:17:41] <roycroft> civil twilight is not for another 11 minutes here
[09:18:02] <chopper79> Howdy all
[09:18:02] <roycroft> does not end, that is
[10:10:20] <IchGucksLive> hi
[10:10:23] <IchGucksLive> What a Day
[10:10:38] <IchGucksLive> i did change the provider Phone and WWW
[10:13:06] <IchGucksLive> now im Down from to 140Mbit to 14Mbit but also from 60Euros a Month to 4
[10:13:29] <IchGucksLive> and only 4GB data
[10:13:38] <IchGucksLive> will see how it comes out
[10:13:49] <IchGucksLive> BEST is all to go
[10:14:06] <IchGucksLive> grap the Router and move around europ
[10:14:24] <IchGucksLive> see you later ;-)
[12:29:18] <IchGucksLive> hi
[12:35:30] <IchGucksLive> nubcake: did you aready printed on the lw cost prusa
[13:01:41] <IchGucksLive> hi JesusAlos did you reatch the 20deg today
[13:11:07] <IchGucksLive> GN8
[13:37:43] <MacGalempsy> sweet. got all the sensors finished.
[13:48:07] <roycroft> i'm looking for some industrial switches - both momentary and maintained
[13:48:14] <roycroft> some lever-actuated, some push-button
[13:48:33] <roycroft> i want to avoid the 22mm telemechanique stuff
[13:48:39] <roycroft> i would like something a little more robust
[13:48:56] <roycroft> does anyone have a favorite brand/vendor for such things?
[13:49:12] <roycroft> i also need some single pole rotary switches
[13:50:35] <roycroft> keep in mind that i like the early to mid-century industrial look
[13:50:51] <roycroft> i'm getting a bunch of jeweled neon indictators
[13:51:28] <JT-Shop> AB 800 pushbuttons are bullet proof
[13:52:55] <roycroft> ab anything is usally pretty bullet proof
[13:53:10] <jdh> we use similar GE switches
[13:53:39] <JesusAlos> IchGucksLive: there are a lott cold today here, about 12deg.
[13:54:06] <JesusAlos> Good night friends
[13:54:17] <jdh> 23c and sunny here
[13:54:49] <roycroft> i generally prefer separate actuators and indicators, but my cnc control panel is going to be very crowded, so i may ogo for some illuminated actuators on that
[13:55:53] <jdh> I really like the AB better, but we are GE
[13:56:22] <JT-Shop> I like the little push in LEDs for panel indicators
[13:57:42] <roycroft> sadly, vintage electronics are getting very hard to find
[14:00:28] <roycroft> i think i have enough switches in my junk drawer to start testing the cnc electronics
[14:00:37] <roycroft> i'm ready to buy stepper drives and motors
[14:00:50] <roycroft> so i'll be able to get that stuff going very soon
[14:01:40] <roycroft> and that reminds me
[14:02:24] <roycroft> http://www.ebay.com/itm/231596049990
[14:02:45] <roycroft> are those motors likely to work decently?
[14:02:59] <roycroft> the ones recommended to me were ~$150 each
[14:03:07] <roycroft> which is more than i had anticipated
[14:03:36] <roycroft> i'm asking if those are likely to be reliable - i know th eparameters are ok for my application
[14:03:49] <Wolf_> same ones I’m using on my X2
[14:03:59] <Wolf_> and the stack of 7 I have…
[14:04:15] <roycroft> i am probably going to use a bigger motor for the z axis
[14:04:24] <roycroft> but i can test with one of those
[14:04:28] <Wolf_> who knows where they are actually made at tho
[14:04:32] <roycroft> and sparing is good anyway
[14:05:22] <roycroft> it seems odd to me, but dual-shaft motors are generally less expensive than single-shaft ones
[14:09:09] <Wolf_> http://www.omc-stepperonline.com/high-torque-nema-23-cnc-stepper-motor-113mm-3nm425ozin-23hs454204s-p-127.html
[14:10:09] <jdh> I have keling 570oz ones
[14:10:35] <jdh> Z is 2:1 and it is fast enough
[14:10:51] <roycroft> ok, i got those motors
[14:11:10] <roycroft> i was thinking about ~600oz/in for z
[14:11:24] <roycroft> so that's in line with what you have
[14:17:10] <Wolf_> hm who was I talking to about 4axis/harmonic drives...
[14:19:02] <jdh> roycroft: what machine?
[14:19:30] <jdh> I could do 1:1 for Z if I dropped the accel
[14:19:40] <jdh> (G0704)
[14:22:38] <Wolf_> maybe sync_
[14:26:15] <archivist> I was around at the time, that blue thing
[14:26:37] <roycroft> x3
[14:26:47] <roycroft> g0463
[14:27:17] <Wolf_> yeah, that blue thing, got message back that it is 21" long overall, and about 8" around at the widest part.
[14:27:42] <roycroft> i have no idea yet how hard it's going to be to move z
[14:28:04] <roycroft> as it is, if i don't lock the head down when i'm operating the machine it vibrates horribly
[14:28:16] <archivist> Wolf_, that sounds.... not small
[14:28:20] <roycroft> i need to disassemble, scrape, perhaps replace the gib
[14:28:34] <roycroft> i just don't know yet, until i take it apart and see what's going on
[14:28:49] <Wolf_> archivist: yeah, not small for sure
[14:29:10] <archivist> roycroft, some chinesium mills the spindle rebuilding
[14:29:30] <roycroft> i'm anticipating i might have to do that
[14:29:52] <roycroft> but there's a gib lock lever on the head
[14:30:00] <roycroft> if i tighten that the vibration mostly goes away
[14:30:07] <archivist> we did a mill twice to get the spindle right
[14:30:25] <roycroft> if i just tighten the gib itself the head won't move smoothly
[14:30:30] <roycroft> so i figure something is not quite flat
[14:30:40] <roycroft> or everything is not quite flat
[14:31:08] <archivist> might need to scrape/file the gib/way
[14:31:16] <roycroft> yes, that's what i figure will be the case
[14:31:30] <Wolf_> look at how bad its made, then figure they used a mill that was built the same to do the finish work on the one you have lol
[14:31:48] <roycroft> i'm doing the cnc conversion from the computer back to the actual machine
[14:31:58] <roycroft> so that i can use the mill as long as possible before doing the final bits of conversion
[14:32:04] <archivist> and they use a blunt cutter so the V sides are not flat
[14:32:25] <roycroft> i'll be able to make the parts i need for the conversion with the mill in its present state
[14:32:55] <roycroft> once i make those it will be time to tear it down and start scraping
[14:32:56] <Wolf_> I wonder if I should look for a big enough surface grinder to put my x2 through
[14:33:11] <roycroft> i'd like to install a one-shot oiler on the machine
[14:33:36] <roycroft> but that would require milling on the saddle and table, which is hard to do when my only mill is down
[14:35:57] <roycroft> i'll come up with a way to do it if i decide to go that route
[14:35:57] <roycroft> i might just do the cnc conversion now, and add one-shot oilater if i feel up to it
[14:36:04] <gregcnc> anyone program lathes behind center, ie negative diameters?
[14:40:23] <roycroft> now as soon as i hear back from gecko i'll be able to purchase drives, and then the fun begins
[14:41:52] <roycroft> and wolf_: you can always hand-scrape your x2
[14:41:58] <roycroft> you don't need a fancy surface grinder
[14:42:14] <roycroft> just a lot of time and patience :)
[14:42:30] <JT-Shop> power scraper!
[14:42:41] <Wolf_> yeah, and a reference
[14:42:50] <roycroft> yeah
[14:42:56] <roycroft> a used biax is only about $500
[14:43:07] <roycroft> a used biax flaker is only about $1500
[14:43:12] <roycroft> so for $2k you can have it all
[14:43:48] <roycroft> a surface plate can be a good reference
[14:44:01] <roycroft> i thought you just destroyed your suspension hauling a bunch of those home
[14:44:20] <archivist> and we know Wolf_ has sufficient surface plates
[14:44:47] <Wolf_> I have a 24x18 plate now, pay the $25/sqft to have it checked and start with scraping in a hump back casting
[14:44:51] <roycroft> that pink speckled starrett will look mighty purty with blue dye smeared all over it
[14:46:21] <Wolf_> yup lol
[14:48:11] <archivist> it is a shame a certain book is not freely available for people who want to learn scraping
[14:49:03] <Wolf_> hmm what book...
[14:49:11] <archivist> Machine tool reconditioning and applications of hand scraping Edward F. Connelly Machine Tool Publications
[14:49:44] * jymmm is getting WAY better at burning out barrels, only took 20 minutes this time =)
[14:50:12] <archivist> https://www.abebooks.com/book-search/title/machine-tool-reconditioning-and-applications-of-hand-scraping/
[14:50:17] <Wolf_> well, its on amazon for $483 lol
[14:50:20] <archivist> rofl at the prices
[14:51:02] <archivist> buy new http://www.machinetoolpublications.com/
[14:51:36] <roycroft> yes, if it's the book i'm thinking of it's a very good bookthat is a great book
[14:51:40] <roycroft> ack
[14:51:51] <roycroft> i meant to just say it's a great book
[14:51:57] <roycroft> but started that before you posted the link
[14:52:02] <sync_> you can just download the badly scanned djvu
[14:52:21] <archivist> I can read the real thing :)
[14:52:41] * roycroft can too
[14:52:47] <Wolf_> yeah I just found a scan
[14:52:52] <roycroft> and i think i paid about $30 for it
[14:52:55] <roycroft> but that was a long time ago
[14:55:41] <archivist> I see it is only Price: $92.95 new
[14:57:08] <roycroft> https://www.amazon.com/Machine-Tool-Reconditioning-Applications-Hardcover/dp/B00YDJCFKC/ref=sr_1_4?s=books&ie=UTF8&qid=1485980844&sr=1-4&keywords=machine+tool+reconditioning
[14:57:09] <archivist> the second hand dealers started hiking prices of "rare" books with automated programs, making fools of themselves
[14:57:17] <roycroft> there's a copy for $2290.94
[14:57:29] <roycroft> that must be a really special one
[14:58:01] <archivist> automates pricing, total cock up considering the new price
[14:58:41] <roycroft> yes, i've found a lot of really wacky prices
[14:58:53] <roycroft> books still in print that are going for 10x or more used than they can be had new
[14:59:08] <roycroft> it's usually technical books where they do that
[14:59:57] <archivist> true value of old technical books is very low usually
[15:00:23] <roycroft> some are worth more than the street price though
[15:00:39] <roycroft> older versions of the toolbox size machinery's handbook are very cheap
[15:00:52] <roycroft> but they are more useful for some things than the current edition
[15:01:07] <JT-Shop> damn windoze 7 shut down and now it's real slow
[15:01:17] <roycroft> since the book cannot grow in physical size, when they add new material they have to delete some older material
[15:02:03] <sync_> I have a copy, but it is useless to me
[15:02:33] <roycroft> btw, for folks in the us, i recently got a copy of "mechanical and metal trades handbook"
[15:02:59] <roycroft> which is an english translation of a standard german book that some claim is their equivalent of machinery's handbook
[15:03:15] <roycroft> it's not even remotely equivalent, but it has a lot of really useful information
[15:03:28] <roycroft> all in si units of course
[15:04:03] <roycroft> i suspect most european and british machinsts are familiar with that book
[15:04:47] <archivist> not one I have seen yet
[15:06:15] <sync_> you mean the tabellenbuch metall
[15:06:20] <sync_> yeah, that one is relatively ok
[15:06:45] <roycroft> https://www.amazon.co.uk/Mechanical-Trades-Handbook-Ulrich-Fischer/dp/3808519142/ref=sr_1_1?s=books&ie=UTF8&qid=1485981391&sr=1-1&keywords=mechanical+and+metal+trades+handbook
[15:06:53] <roycroft> yes, sync_, tabellenbuck metall
[15:07:12] <roycroft> archivist: in that listing on amazon there's an email address at the bottom where you can request a pdf of the toc
[15:07:37] <roycroft> sync_: what i like is that the information in it is very well organized, and it is well-illustrated
[15:07:47] <sync_> that is because it is designed for schools
[15:07:49] <roycroft> machinery's handbook has about 50x as much information
[15:08:04] <Nick-Shop> That's a book I bought in early 70's so I could recondition war horses for my shop. I guess I'll hang onto it :-)
[15:08:23] <roycroft> eek
[15:08:25] <roycroft> it is lunch time
[15:08:27] <archivist> roycroft, the contents pdf is on the publishers site too
[15:08:34] * roycroft heads out to lunch
[15:08:38] <roycroft> oh, great
[15:08:56] <roycroft> that's a lot easier than an email exchange
[15:09:20] <archivist> http://www.machinetoolpublications.com/about.cfm
[15:09:32] <archivist> see bottom of page
[15:09:34] <sync_> I grabbed a copy of the machinery's handbook but idk, I so far have not found a lot of information in there that is actually useful
[15:21:59] <Wolf_> so… 8” dia x 21” (I think including the servo) harmonic drive might be a bit big for 4th build
[15:22:26] <archivist> think big :)
[15:23:28] <archivist> mount it under the machine to rotate it
[15:23:57] <Wolf_> I usually think big lol
[15:26:30] <sync_> yeah it is too large Wolf_
[15:28:10] <Wolf_> http://www.ebay.com/itm/291996589239 IDK, if that rear flange is 8”, the blue section should only be about 10-12”
[15:28:47] <Wolf_> I have the option to drive out and look at it
[15:30:08] <sync_> nah get something with a smaller harmonic drive
[15:31:10] <archivist> or use it for tilting vehicles for welding the chassis
[15:31:17] <Wolf_> lol
[15:31:48] <Wolf_> 4th axis for the K&T #2
[15:42:54] <membiblio> How do you handle an extra tool device on a cnc with linuxcnc - I have two spindles but I also have two side drills and a bunch of other tools - does linuxcnc know about 'other' tools?
[16:08:33] <roycroft> awesome
[16:08:41] <roycroft> gecko responded about warranty, so now i can order my drives
[16:14:36] <roycroft> i assume i can do some bench testing of the drives without a heat sink
[16:15:37] <XXCoder> I guess it depends on how fast it generates heat
[16:16:47] <roycroft> i can monitor pretty closely
[16:17:00] <roycroft> i haven't worked on the layout of my electronics enclosure yet
[16:17:17] <roycroft> i don't know if i'm going to mount the drives individually or all in line on a single heat sink
[16:17:26] <roycroft> i need to start thinking about that stuff
[16:18:10] <roycroft> i have a bank of fans from an old rack mount computer that would work great if i mounted the drives individually and lined them up parallel to each other
[16:19:11] <roycroft> and ack!
[16:19:44] <roycroft> i almost just decomissioned a server but remembered at the last minute that it's at ftp server for a buttload of fiber optic and other network elements
[16:19:58] * roycroft migrates that stuff quickly
[16:20:03] <XXCoder> lol
[16:20:11] <roycroft> i could have recovered the stuff from backups
[16:20:26] <roycroft> but if i didn't remember i would not know until something needed to be rebooted/reloaded
[16:20:33] <XXCoder> should have "Hi my name is <servername> and I do <list of stuff>" on each server
[16:20:34] <roycroft> which is not the time to start setting up a tftp server
[16:20:41] <roycroft> i mostly have that
[16:21:49] <XXCoder> cool
[16:22:08] <roycroft> we're moving to virtualizing everything
[16:22:24] <roycroft> all new machines, except for sans/other specialized machines, get hypervisors installed
[16:22:33] <roycroft> and i usually spin off a vm for every service
[16:22:42] <roycroft> or, at least, every closely-related set of services
[16:23:13] <roycroft> instead of having a small number of machines each of whic hdoes a lot of things, i have a large number of vms, each of which does very specific things
[16:23:40] <roycroft> but i'm not going to spin off a dedicated tftp server for the optical gear - my noc management machine can do that
[16:44:09] <MacGalempsy> well this is great. getting closer on the PID tuning of the X axis
[16:51:20] <Deejay> gn8
[17:06:29] <JT-Shop2> after 3 45 minute phone calls I really understand how lost a windoze mark3 user is...
[17:13:08] <andypugh> Can you tell what it is yet? https://goo.gl/photos/rcJZY8eanvjgN2wS9
[17:14:46] <gregcnc> I love many gears
[17:15:22] <JT-Shop2> a clock
[17:15:41] <JT-Shop2> very beautiful one at that
[17:15:42] <andypugh> There are 27 gears in that assembly.
[17:15:56] <JT-Shop2> how big is that?
[17:16:07] <JT-Shop2> no sense of scale in the photo
[17:16:46] <andypugh> 4.5” to the top gear
[17:17:08] <andypugh> It’s fairly hefty. Not watch-sized.
[17:17:29] <JT-Shop2> but smaller than the final drive on my dozer
[17:17:42] <andypugh> I would anticipate so, yes.
[17:17:57] <andypugh> I do plan on making a the gears for a friend’s truck.
[17:30:26] <BeachBumPete> andypugh did you make that? impressive
[17:36:07] <Nick-Shop> looks like a planetary gear drive of some kind
[17:36:44] <andypugh> It’s a 4-way co-axial differential
[17:37:24] <andypugh> The drive goes in the wider gear near the bottom, and equal torque comes out the 4 large and thinner gears.
[17:38:41] <Nick-Shop> someone spent a lot of time building that - is it brass or plated?
[17:39:18] <lunada> andypugh, are you on?
[17:39:34] <lunada> i have a question about your carousel component
[17:40:21] <andypugh> yeah, I am here
[17:41:29] <lunada> sweet. on the encoder types, i have a single sensor that triggers once per tool position. is that single, or index?
[17:42:16] <andypugh> Single, but how does it know where it is?
[17:42:34] <lunada> i have a second sensor for home position (pocket 1)
[17:43:04] <cradek> a little bounce and you'll get off a pocket and crash
[17:43:15] <cradek> it's much better to add a third sensor and have quadrature for the motion
[17:43:54] <andypugh> Certainly worth a good long debounce..
[17:43:56] <lunada> cant i just debounce it?
[17:44:07] <cradek> can it only ever move one direction?
[17:44:23] <lunada> no, it moves in both
[17:44:47] <cradek> it's much better to add a third sensor and have quadrature for the motion
[17:44:48] <cradek> heh
[17:45:00] <andypugh> lunada: I think you would use “index” for your system
[17:45:52] <andypugh> cradek: Unfortunately “carousel” does not currently support quadrature.
[17:46:27] <lunada> andy, i was going to try index but it said carousel.0.sense-1 doesnt exist as soon as i changed it from single to index?
[17:47:10] <andypugh> That’s not what the docs say should happen
[17:47:17] <lunada> right
[17:49:00] <lunada> i have a homing sequence in ladder because i was originally was going to use modmath to figure out my carousel direction but then i found the carousel component and figured id try that
[17:49:17] <andypugh> lunada: Looks OK here: http://www.pastebin.ca/3762787
[17:52:26] <lunada> i'll give it another shot. do the carousel fwd and rev pins become false when it hits the target pocket?
[17:52:42] <andypugh> Yes
[17:52:56] <lunada> sweet
[17:54:43] <lunada> do they also become false if the iocontrol.0.tool-change pin goes false or the iocontrol.0.tool-changed pin goes true?
[17:55:35] <andypugh> No. Because the component only knows about things it can see on its input pins.
[17:56:35] <andypugh> But: if you connect carousel.0.enable to tool-change-request and that goes false, then the component will set both outputs to false.
[17:57:35] <andypugh> (by tool-change-request I do mean iocontrol.0.tool-change )
[17:59:14] <lunada> ok cool. Just making sure. I havent gotten it working yet, but i do have some weird problem where my iocontrol.0.tool-changed pin goes true and my iocontrol.0.tool-change pin goes false in the middle of the toolchange even though i #'d out those pins in hal
[18:00:14] <lunada> i'm using some of my old hal file from a much older version of linuxcnc, so i dont know if something changed and it isnt cooperating
[18:00:45] <andypugh> tool-changed only goes true if you set it true, it’s an input pin.
[18:01:09] <andypugh> Perhaps it is connected to something in HAL, somewhere?
[18:01:15] <lunada> one would think but that pin is commented out completely
[18:01:32] <lunada> it was connected to a pin in classicladder
[18:01:51] <andypugh> Is it unconneted in every HAL file?
[18:01:51] <lunada> but i commented it out once i saw it was going true
[18:02:56] <lunada> i'll double check.... i didnt think there was another hal in there but i suppose it is possible
[18:04:25] <lunada> can it be connected to two different signals at the same time without throwing a fit when i start Axis?
[18:08:04] <andypugh> No, it can only be connected to one signal, but that signal could be connected to othe things.
[18:08:21] <JT-Shop2> lunada: open a terminal in your configuration directory and say grep -irl 'ioiocontrol.0.tool-changed' *
[18:11:14] <lunada> no other hal files except the one pyvcp which doesnt have anything
[18:11:43] <lunada> thanks jt-shop, i'll try that
[18:15:09] <JT-Shop2> if you only have one hal file search for the pin then search for the signal
[18:17:16] <JT-Shop2> andypugh: why is homing and homed in the carousel component a parameter?
[18:17:23] <andypugh> Interesting: I have some big carbide spade-bits here. They are magnetic. They stick to each other. Not seen that before.
[18:17:46] <lunada> oh i already know where the signal is
[18:17:49] <JT-Shop2> solid carbide?
[18:18:04] <JT-Shop2> but do you have the signal twice?
[18:18:08] <lunada> no
[18:18:22] <andypugh> JT-Shop2: They are parameters because I lacked the imagination to think why anyone would want them as pins
[18:18:30] <JT-Shop2> sounds like your ladder is where the problem is
[18:18:38] <lunada> i'll check again for sanity's sake
[18:18:57] <andypugh> JT-Shop2: Yes, as far as I know. The only explanation has to be a significant cobalt, nickel or iron content.
[18:19:28] <JT-Shop2> magnetic carbide is a odd one for me
[18:19:37] <lunada> i'll have to screen shot my ladder, it's pretty simple
[18:19:58] <lunada> and the toolchanged pin isnt even in it at the moment
[18:20:24] <JT-Shop2> very strange
[18:20:38] <lunada> ive been pulling my hair out for 3 days on it
[18:20:46] <andypugh> Wikipedia tells me that cobalt is the binder metal used in cemented carbide tooling, so that fits.
[18:21:00] <JT-Shop2> ah that makes sense
[18:21:49] <JT-Shop2> see everyone in the morning... time to cook
[18:21:54] <lunada> seeya
[18:22:26] <JT-Shop2> lunada what's your general location
[18:22:41] <lunada> california
[18:22:53] <JT-Shop2> still early for you then
[18:22:59] <lunada> yep, 4
[18:23:21] <JT-Shop2> I'll listen to I.G.Y. first then cook
[18:23:22] <lunada> u?
[18:23:39] <JT-Shop2> Swamp East Missouri
[18:23:51] <lunada> ah cool.

[18:24:57] <JT-Shop2> ^ I.G.Y.
[19:04:19] <Mac-Phone> anyone get anything done today?
[19:19:37] <Tom_L> nothing worth bragging about
[19:20:27] <BeachBumPete> meh no not really
[19:21:11] <BeachBumPete> still working on this 3d model hehe
[19:28:11] <Mac-Phone> sounds exciting
[19:28:43] <andypugh> Mac-Phone: I did :-)
[19:29:09] <Mac-Phone> andypugh: like what?
[19:29:18] <andypugh> https://goo.gl/photos/ERy9Zzv4u4w1avv3A
[19:30:15] <andypugh> I put it together today. It has taken rather more than one day. In fact rather more than one month.
[19:30:22] <Mac-Phone> that looks great. compliacted. what does it do?
[19:30:46] <andypugh> It’s a 4-output differential gear.
[19:31:26] <Mac-Phone> wow. 4 outputs?
[19:32:49] <Mac-Phone> how long did that take to design?
[19:33:41] <Tom_L> andypugh did you redo the small gears to get that one to fit right?
[19:34:50] <andypugh> I came up with the idea about 8 years ago. Then decided I needed CNC to make it. And have been rather working on the CNC (And LinuxCNC) since.
[19:35:43] <andypugh> Tom_L: Yes, I re-made the outer gears to be divisible by 3, it works a lot better.
[19:36:11] <Mac-Phone> heh. funny how much time on getting the machines together.
[19:37:15] <Mac-Phone> easy to forget about the origins of things sometimes
[19:39:26] <andypugh> Mac-Phone: Well, I went from https://goo.gl/photos/5nuE5AMRjrnofUZ79 to this https://goo.gl/photos/md572fHGgEi9PBK8A and https://goo.gl/photos/Z6F83gAhUh4oG8av5
[19:41:52] <andypugh> And I spent a fair bit of time writing the drivers to run all the Mesa hardware I am using. (buidling on work by others, I should stress. I was very impressed that seb_kuzminsky seemed to have anticipated everywhere where things might grow in the future when he built the underlying architecture.
[19:45:13] <Mac-Phone> after getting deeper into the knowledge base a bit deeper, this whole effort becomes more impressive
[19:49:24] <Mac-Phone> does your mill have a 4th axis?
[19:49:50] <andypugh> Yes, I converted a BS0 dividing head
[19:50:59] <Mac-Phone> is what you used to cut the gears?
[19:51:14] <Mac-Phone> is that*
[19:51:59] <andypugh> Yes: https://www.youtube.com/watch?v=QCReXbT7mQ4
[19:53:30] <andypugh> (LinuxCNC makes it pretty easy to hob gears with a spiral hob)
[19:55:15] <Mac-Phone> can the mill be run as 5 axis with the horz. output?
[19:55:52] <andypugh> Well, yes, in theory, but there would be no cutting tool :-)
[19:57:34] <Mac-Phone> ahhh ok
[19:58:02] <andypugh> The vertical head can tilt. I have considered configuring the tilt as a manual axis, not controlled by LinuxCNC but incuded in the kinematics calculations.
[19:59:36] <Mac-Phone> so only power to one cutting output at a time. what letter would the tilting head be? u v or w?
[20:01:13] <andypugh> B
[20:01:23] <andypugh> But would feed on W
[20:02:27] <andypugh> So, jog fictional-B axis to match the angle set by hand, then W-feeds would drill at angles.
[20:04:05] <andypugh> For jobs like this: https://goo.gl/photos/75apXr4gDN8qRSrk6
[20:04:40] <andypugh> Though actually I just dod that with MDI, as you can not-quite-see in the background.
[20:09:54] <renesis> http://stores.ebay.com/Carbide-Tool-Source
[20:10:23] <renesis> guys i think my fav carbide factory back door seller is back
[20:11:11] <Mac-Phone> is the head tilt adjusted w gears or friction fit?
[20:13:31] <andypugh> Clamp bolts
[20:16:03] <Mac-Phone> i can tell that the cap circuit we worked on is helping a lot
[20:16:40] <Mac-Phone> did some work on the oid tuning today before this cold knocked me out
[20:16:51] <Mac-Phone> *pid
[20:18:13] <chopper79> I was fixing dependency issues all day and my hard drive stopped spinning.
[20:18:17] <chopper79> Work lost
[20:25:06] <Mac-Phone> amazing how much easier it is to tune without that pesky ripple
[20:25:22] <BeachBumPete> I love ripple ;)
[20:25:47] <Mac-Phone> chopper79: did you order the ssd from jt yet?
[20:25:57] <Mac-Phone> :)
[20:28:02] <Mac-Phone> that was to ripple
[20:35:18] <roycroft> ripple is one of my favorite grateful dead songs
[20:41:20] <chopper79> Not yet... Need to just keep forgetting.
[20:42:17] <chopper79> My side project that it was for is not pressing. That is why I was working on builds
[20:42:59] <chopper79> The current project though is pressing. Going to just use wheezy until I am in a better position to change over
[20:43:31] <Mac-Phone> i would like to know how to get multiple panes on mint
[20:46:50] <chopper79> Like splitting the screen in 4
[20:49:47] <chopper79> I did that with compiz a few years ago
[20:50:40] <Mac-Phone> no. like in the std distribution there is a gui that allows the user to flip thru different monitorsn but only 1 monitor
[20:51:12] <chopper79> gotcha
[20:53:42] <Wolf_> Mac-Phone: workspaces
[20:54:04] <Wolf_> Mac-Phone: https://www.youtube.com/watch?v=AHF14E5kHdU
[20:54:26] <Wolf_> try cursor to top left corner
[20:54:56] <Wolf_> or ctrl+alt+up arrow
[20:56:17] <Mac-Phone> [l alt] + [f1]
[20:59:00] <chopper79> If you right click on tool bar and go to "add to panel" then scroll down to "workspace switcher"
[20:59:12] <chopper79> Then is gives you the 4 workspace in the tool bar.
[21:01:46] <rue_shop3> I dont understand how to set the position of G54
[21:01:48] <rue_shop3> ?
[21:03:49] <chopper79> or do you want the Cover Flow
[21:04:41] <rue_shop3> G92?
[21:05:58] <rue_shop3> is G92 relaitve?
[21:08:55] <rue_shop3> does anyone know how to clear G54 to 0,0,0 with G92?
[21:10:34] <Mac-Phone> thanks guys
[21:10:55] <Mac-Phone> home
[21:10:57] <rue_shop3> nobody anywhere shows how to USE G92, they just talk about its use
[21:11:03] <Mac-Phone> then touchoff
[21:11:32] <Mac-Phone> thats g54
[21:11:59] <rue_shop3> I want to set G54 to 0,0,0
[21:12:08] <rue_shop3> what do I use to do that?
[21:13:44] <rue_shop3> does anyone know how to set G54 to 0,0,0?
[21:15:03] <Mac-Phone> are u using an edge finder or probe?
[21:15:08] <rue_shop3> I'm not
[21:15:11] <rue_shop3> I'm hand coding
[21:15:15] <rue_shop3> I want to clear G54
[21:15:42] <rue_shop3> all I want to do is manually set G54 to 0,0,0
[21:16:03] <Mac-Phone> you do that by touching off the workpiece
[21:16:35] <rue_shop3> I dont have a workpeice or a program or a probe, right now G54 is set to 3,4,5 and I want it to be 0,0,0
[21:16:42] <Mac-Phone> once touched off
[21:17:15] <rue_shop3> no
[21:17:21] <rue_shop3> I just want it to be 0,0,0
[21:17:45] <Wolf_> then hit touch off for each axis
[21:18:02] <Mac-Phone> g54 is a coordinate reference system
[21:18:10] <rue_shop3> and if this is going in a program?
[21:18:24] <rue_shop3> is there not a way to do this by just issuing commands?
[21:18:56] <Mac-Phone> if you have a probe yes. else its manual
[21:20:02] <rue_shop3> so, without a probe, I cant set the G54
[21:20:32] <rue_shop3> so I cant have a program set a few different locations and call a cycle on them?
[21:22:07] <Mac-Phone> the origins are set on the machine. the program references the "touch off" origin
[21:22:39] <Mac-Phone> thats why there are setup guys and programmers in some shops
[21:23:12] <Wolf_> there should be a way to set G54 at home locations
[21:24:22] <Wolf_> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?CoordinateSystems down at 3. So if you're lost, what should you do
[21:29:50] <rue_shop3> hah, it worked, but I'm not sure how
[21:30:17] <rue_shop3> but it looks like if i want to set g54 to anything, its a complete pain, I cant just set the position
[21:30:57] <Wolf_> try g10
[21:31:52] <Wolf_> g10 L2 P1
[21:32:04] <Wolf_> http://linuxcnc.org/docs/2.6/html/gcode/gcode.html#sec:G10-L2_
[21:34:31] <Mac-Phone> what kind of machine are you running?
[21:36:40] <Mac-Phone> Wolf_ if tuning goes right this machine should be able to rigid tap
[21:36:50] <Wolf_> nice
[21:38:24] <Mac-Phone> want to make a couple subplates
[21:41:33] <Mac-Phone> so is your plan to use one probe as a toolsetter?
[21:45:35] <Wolf_> actually I was planning on using granite plate (with hole) + height gauge to set the tool lengths, but a tool setter on the table is something I want to look at
[21:47:49] <roycroft> i'm planning on using the surface plate with holder and height gauge to set tool lengths
[21:48:03] <roycroft> i have a small surface plate (12x18) that i can use for that
[21:48:15] <roycroft> it seems a good way to do it
[21:49:12] <roycroft> there's another money sink coming up soon - all those tormach tool holders
[21:49:59] <roycroft> if i would just go ahead and buy a new lathe i'd be able to make my own
[21:54:45] <Wolf_> I dunno about diy ER collet tool holders
[22:02:53] <Tom_L> Mac-Phone, rigid tapping is cool
[22:03:07] <Tom_L> no reason you can't get it to work
[22:03:27] <Mac-Phone> the vids in the wiki are sweet
[22:03:38] <Mac-Phone> so fast.
[22:03:41] <Tom_L> i did it on my sherline
[22:03:54] <Tom_L> so if i can get that to work surely yours will
[22:04:24] <Tom_L> i even modded my cad cam post for it
[22:05:03] <Mac-Phone> the fusion360 post processor should have it
[22:05:21] <Mac-Phone> threadmills cost $
[22:05:31] <Tom_L> i know
[22:06:07] <Mac-Phone> i wonder if there is rigid dieing?
[22:06:20] <Tom_L> same thing really
[22:06:57] <Mac-Phone> just need the toolholder
[22:14:26] <gogbob> <-- newbie - ive set up this little table drill, with XYZ axes... when i try to run the default LinuxCNC "schematic" that is shown default, my drill is rounding edges, instead of slowing down to reach sharp corners - ive read something about using G64 with .001 mm precision - whre does one set these things ? is it in the design of the "schematic"(cad software)? or is it a drill setting along
[22:14:26] <gogbob> with speed and accelleration (LinuxCNC config wizard)?
[22:15:00] <Tom_L> i believe you put it in your gcode file
[22:15:25] <Mac-Phone> yeah near the top
[22:15:36] <Mac-Phone> by the feedrate
[22:15:41] <gogbob> the Gcode file is the file output from the designing program ?
[22:15:42] <Tom_L> http://linuxcnc.org/docs/2.7/html/gcode/g-code.html#gcode:g64
[22:16:10] <gogbob> or is the Gcode file a reference to the ini files for the drill config ?
[22:16:16] <Mac-Phone> servo or stepper?
[22:16:57] <Mac-Phone> gcode
[22:19:38] <gogbob> i have no idea what im doing, or what im messing around with... im IT support, thats rebuilding a linuxcnc machine for a freind... ive gotten the drill to move as it should, so 10mm in the default schematic is 10mm on the drill... but its rounding edges... so im guessing its in the text window part, the "CODE" part... near the top
[22:20:23] <Mac-Phone> usually its because the machine acceloration is too slow
[22:21:43] <roycroft> gogbob: g-code is the name of the programming language for most modern cnc machines
[22:22:00] <gogbob> yeah, that does sound like something that makes sense... but as i understand it, i can force it to goto the corners with G61... or with 0.001 mm tolerance through G64...
[22:22:00] <Mac-Phone> acc is in the ini but i wouldnt change anything as an it guy ;)
[22:22:06] <gogbob> ok thanks roy
[22:22:09] <roycroft> typically you would design a part using cad software, then cam software would translate that drawing into the machine readable g-code
[22:22:24] <roycroft> http://gnipsel.com/linuxcnc/g-code/index.html
[22:22:36] <roycroft> if you go there you'll find a really good, concise, clear introduction to g-code
[22:22:44] <gogbob> so G64/G61 is set through the designing part, thank you
[22:23:02] <roycroft> and you'll see discussion in the preamble section of path blending (g64)
[22:23:25] <roycroft> your cam software will output the g-code
[22:23:50] <roycroft> you either take that file (which is a text file) and upload it to your cnc computer, or the cam software will directly load it to the cnc computer
[22:24:04] <roycroft> in either case, there will be an opportunity to hand-edit the g-code before running it
[22:24:49] <roycroft> so if your cam software cannot adjust the path blending granularity, or you cannot figure out how to do it, you can always take the g-code file it produces and hand-edit to adjust g64 to your liking
[22:25:44] <gogbob> sweet roy, thanks for the help
[22:27:15] <roycroft> you will not set the path blending in the cad software
[22:27:27] <roycroft> you should be able to set it in the cam software
[22:27:45] <roycroft> and just to confuse matters, some cam software is integrated with the cad software
[22:27:49] <gogbob> im only concerned with the configuration of the drill
[22:28:15] <roycroft> iirc g64 is not a persistent value on the machine
[22:28:25] <roycroft> i believe it defaults to fastest path
[22:28:42] <roycroft> and you have to explicitly set it for every program you run if you want it to not be fastest path
[22:29:01] <gogbob> yeah, it seems like its more concerned with not loosing speed, rather than actually hitting the design
[22:29:11] <roycroft> that may vary from interpreter to interpreter
[22:29:20] <roycroft> yes, exactly
[22:29:31] <roycroft> and you may want to change it in the middle of your program
[22:29:37] <roycroft> you might want to do fastest path for roughing
[22:29:43] <gogbob> nothing advanced please
[22:29:49] <roycroft> and then tighten it up when you approach your finish passes
[22:29:59] <gogbob> changing stuff midprogram we will let the pros handle
[22:30:41] <cncnoob> Howdy all
[22:31:00] <roycroft> good programming practice would be to use a consistent preamble in every g-code program you produce that sets homing and all defaults, including your path blending preference
[22:31:12] <cncnoob> Just got my 44991 mini mill converted to CNC
[22:31:52] <cncnoob> Things are moving, but I'm a little confused which direction +/- should actually be moving each axis
[22:32:21] <cncnoob> Right now when I + the Z axis it moves up
[22:32:26] <cncnoob> is that standard?
[22:33:35] <gogbob> i had the same problem, i went through the configuration wizard, and checked of "inverted" in the part about which port controls Z axis
[22:33:43] <gogbob> not with your mill
[22:34:06] <gogbob> mine is a generic noname brand, but borth Z & Y axes needed to be inverted
[22:35:18] <cncnoob> Ok, so to clarify, when the Z axis is all the way up the machine coordinate for that axis should be zero correct?
[22:35:42] <roycroft> zero is wherever you want it to be :)
[22:35:46] <cncnoob> As opposed to 9.875 which is my Z axis travel and what I'm currently seeing
[22:35:55] <cncnoob> Well I guess that is my other problem
[22:36:05] <cncnoob> I cannot figure out how to make zero where I want it
[22:36:24] <Wolf_> Z axis, 0 at top. negative towards the table
[22:36:35] <gogbob> you set it whereever it has to be, and then "home" it
[22:36:39] <Wolf_> home is usually top of travel
[22:36:48] <cncnoob> right, I have done that
[22:37:15] <cncnoob> The problem is that my cam software does a g28 and zeros everything
[22:37:28] <cncnoob> right now that is driving the z axis down instead of up
[22:37:39] <cncnoob> also driving the y axis back instead of forward
[22:37:58] <gogbob> then go through the config wiz, and invert those channels
[22:38:08] <cncnoob> ok i'll give that a try
[22:38:21] <cncnoob> Would that mean I have my driver wired backwards?
[22:38:41] <roycroft> when manually milling, x0 y0 is usually the upper left corner of the part
[22:38:41] <cncnoob> I'm pretty sure I have it wired correctly per the docs that they came with
[22:38:51] <roycroft> so moving to the right would increment x
[22:38:59] <roycroft> which would actually be moving the table to the left
[22:39:12] <cncnoob> ok good roycroft
[22:39:20] <cncnoob> that is what I was aiming for
[22:39:25] <roycroft> moving towards you would increment y
[22:39:31] <roycroft> which would actually be moving the saddle away from you
[22:39:37] <cncnoob> humm
[22:39:41] <roycroft> since your part is what moves, not the tool
[22:40:40] <cncnoob> so looking down at the mill I would expect that x0 y0 would have the bulk of the table hanging off to the right correct?
[22:40:51] <roycroft> that is the convention
[22:40:53] <cncnoob> and the saddle moved all the way forward
[22:41:23] <cncnoob> Good that is what I'm trying to get so at least I'm justified there
[22:41:28] <gogbob> https://youtu.be/3oHmX0BqeRg?t=320 after each box is a little checkmark boxes, that let you invert any channels... just invert Z&Y
[22:41:31] <cncnoob> I'll invert those pins and see what happens
[22:42:10] <rue_shop3> thanks!
[22:42:16] <roycroft> your software should have a mechanism to run a program in simulation mode, and show the tool paths on the display
[22:42:18] <roycroft> run that
[22:42:33] <roycroft> then run the program on the machine without tooling - do an "air" cut
[22:42:39] <roycroft> and see if the machine follows the simulation
[22:44:02] <roycroft> just remember that when you see a toolpath move to the right in simulation, your machine will move to the left
[22:44:21] <cncnoob> Yup, I ran the sim and it looked good
[22:44:22] <roycroft> simulation mode will have a stationary part
[22:44:35] <cncnoob> I also ran it on air and the only problem is at the start and the end
[22:44:36] <roycroft> the machine will have a stationary spindle
[22:45:16] <cncnoob> My gcode has this
[22:45:17] <cncnoob> G91 G28 Z0
[22:45:19] <cncnoob> G28 X0 Y0
[22:45:38] <cncnoob> Right now that is only correct for the X axis
[22:45:55] <cncnoob> it causes the z axis to move down and the Y axis to move back
[22:46:36] <cncnoob> @gogbob
[22:46:44] <cncnoob> in that video he only inverts the step pins
[22:46:57] <roycroft> your machine setup will let you invert the pins to flip the direction
[22:46:57] <cncnoob> would I want to invert only the direction pins, only the step pins, or both?
[22:47:27] <Wolf_> dir only
[22:47:39] <cncnoob> Ok will do
[22:49:29] <Mac-Phone> cncnoob check out the integrators manual on the website.
[22:49:42] <Mac-Phone> its a great place to start
[22:50:27] <Wolf_> unless you have no basic knowlege
[22:50:53] <Mac-Phone> http://linuxcnc.org/docs/html/
[22:51:41] <Mac-Phone> it gives basic knowledge
[22:52:07] <Mac-Phone> cnc machine overview
[22:53:27] <Mac-Phone> even tells you which way is +y ;)
[22:57:36] <Wolf_> does it have stepper driver theory and application in there?
[23:04:52] <cncnoob> Most people have their machines set up so when they use the arrow keys the work moves in the direction the arrow key indicates correct?
[23:05:10] <cncnoob> So I push the left arrow I would expect the work to move left?
[23:08:02] <Mac-Phone> think about how the cutter moves not the table
[23:08:33] <cncnoob> Ok so opposite of what I was saying
[23:10:14] <Mac-Phone> think of arrow keys as + - not dir
[23:10:48] <Mac-Phone> right arrow +x
[23:11:40] <Mac-Phone> alright have fun folks ttyl
[23:14:32] <roycroft> if you push the left arrow the work should move to the right
[23:14:45] <roycroft> and that takes a while to wrap your head around
[23:15:02] <roycroft> but everything is from the tool's point of view, not yours
[23:24:01] <cncnoob> Yeah I think I understood that, but it is confusing because I can't get it to move the standard way
[23:24:29] <cncnoob> I have the x axis working correctly and I'm now working on the y axis
[23:24:46] <cncnoob> on the x axis I inverted the pin and left the scale positive
[23:26:01] <cncnoob> for the y axis I have tired all combinations of scale (+/-) and pin inversion and the y axis will either 1.) move in the correct direction OR 2.) be zeroed where I want it.
[23:26:05] <cncnoob> Not both :(
[23:26:21] <Wolf_> the DIR pin is high/low (on/off) and just tells the motor to go clockwise/counter clockwise
[23:29:08] <Wolf_> if you have hit home. the axis won’t got past set points
[23:32:01] <cncnoob> My problem is that I want the y axis zero position to be with the saddle all the way towards me
[23:32:15] <cncnoob> the y axis has 3.8xx" of travel
[23:33:08] <cncnoob> I want the y coordinate to be 3.8xx" when the saddle is the furthest away from me as it can be
[23:33:38] <cncnoob> right now when I home the y axis it thinks it is all the way back away from me, so it will not move back any more
[23:34:14] <cncnoob> but it will attempt to move forward which is not possible since a big piece of metal is there :)
[23:39:26] <Wolf_> machine setup is fun lol
[23:44:15] <cncnoob> just to clarify here is a pic of my machine with all axises in their zero positions goo.gl/MWoLWH
[23:45:09] <cncnoob> http://goo.gl/MWoLWH
[23:46:11] <Wolf_> X is wrong way :P
[23:46:52] <cncnoob> it is?
[23:47:01] <cncnoob> That would put the bit at the top left of the work
[23:47:12] <cncnoob> it is the only axis that I *thought* was working correctly
[23:49:55] <cncnoob> That is to say, If I had some work mounted the position that the axises are in my picture would the bit as far behind and to the left of the work as possible
[23:50:33] <Wolf_> http://linuxcnc.org/docs/html/user/user-concepts.html
[23:53:05] <Wolf_> I’m confused now
[23:53:41] <Wolf_> I think your x is right
[23:54:01] <Wolf_> my X1 is backwards on the X axis lol
[23:54:16] <roycroft> you can set up your coorinate system(s) any way you want
[23:54:22] <roycroft> coordinate
[23:54:32] <roycroft> but everyone has to agree about what they are
[23:54:42] <Wolf_> x/y isn’t bad
[23:54:54] <Wolf_> Z tends to cause issues if you make up your own
[23:54:57] <roycroft> you, your cam software, your machine setup all have to agree
[23:55:10] <roycroft> x origin can be on the right if you want
[23:55:54] <roycroft> i still machine manually, but i will sometimes work with the x origin on the right instead of the left
[23:57:33] <roycroft> if i'm making a part with a lot of features, instead of dimensioning everything from a single origin, i'll dimension from an x left, y upper origin and an x right, y upper or lower origin
[23:57:34] <cncnoob> Any thoughts how I can tame this beast? If I'm trying to set it up in a non-standard way I don't want to do that
[23:57:49] <roycroft> it depends on what i need to do to make a clear drawing
[23:58:07] <Wolf_> mostly just need to make sure you don’t have something mirrored
[23:58:22] <roycroft> and when i machine the part i just use the origins i used in the drawing for a particular feature
