[00:01:19] <pink_vampire> I love probing.
[00:01:26] <pink_vampire> I saw you have the TP2
[00:01:38] <pink_vampire> I did my own probe.
[00:02:04] <Wolf_> tmi
[00:02:55] <pink_vampire> MacGalempsy: and I need to finish with the 2 small parts, but before that I need to take care the house.
[00:03:09] <MacGalempsy> cool. i want to make a probe for toolsetting. how did yours come out?
[00:05:22] <pink_vampire> I'm sorry I's take me a bit time to answer, I'm folding the laundry and talking to you in the same time.
[00:06:32] <pink_vampire> MacGalempsy: http://i.imgur.com/Q73eAKv.png this is the prove that I made (few years ago, it was one of my first projects on the machine)
[00:08:46] <MacGalempsy> nice! i want to convert this tp1 to wireless so it will load to the atc and not get tangled
[00:08:48] <pink_vampire> probe*
[00:09:21] <pink_vampire> it is very easy to do
[00:09:50] <pink_vampire> you just need small transmitter and receiver
[00:12:06] <pink_vampire> how much the probe cost you?
[00:12:49] <MacGalempsy> i got the set of tp1 tp2 and tips for like 300
[00:13:10] <MacGalempsy> the interface was 50
[00:13:18] <pink_vampire> that is very cheap.
[00:13:32] <pink_vampire> where did you got them?
[00:13:46] <MacGalempsy> ebay listing was on for 2min w buy it now
[00:14:30] <pink_vampire> that is amazing!
[00:16:06] <archivist> renishaw is cheaper in US, I bought a socket over there and had it shipped
[00:16:53] * roycroft is leaning heavily towards haimer
[00:17:20] <roycroft> they don't seem to be available for less than list price though
[00:17:35] <archivist> MacGalempsy, beware of gemma board, there are two versions one does not work on the arduino IDE
[00:18:14] <archivist> and not enough pins to be useful
[00:19:17] <MacGalempsy> archivist going to use the trinket. got one the other day to play with
[00:19:37] <archivist> the tinylily ?
[00:19:59] <MacGalempsy> adafruit trinket is the name
[00:20:39] <MacGalempsy> it has 5 or 6 pins
[00:21:35] <archivist> adafruit gemma did not work on the arduino programmer, seems adafruit do something different with boot loaders
[00:22:53] <MacGalempsy> it is supposed to be cold tomorrow, so after getting some operations going, i'll mess w some coding tutorials.
[00:23:15] <MacGalempsy> hmmm
[00:24:20] <MacGalempsy> the adafruit turorial shows it connecting to the arduino ide
[00:24:34] <MacGalempsy> hopefully it works
[00:25:27] <archivist> except there is bugger all docs to tell the ide to know about the adafruit devices (not on menu)
[00:26:09] <archivist> there are libraries I could load but didnt find one
[00:29:33] <MacGalempsy> they mentioned some libraries wouldnt work
[00:32:00] <archivist> in my IDE there are no adafruits devices in the drop down selector for devices to program
[00:50:32] <floppydisk_ph> Te s t
[00:51:00] <Wolf_> error, T e s t not found
[00:51:34] <floppydisk_ph> Found just fine on my phone
[00:56:02] <pink_vampire> floppydisk_ph: mmmm
[00:57:49] <archivist> often phones and wifi cannot keep a stable connection
[01:02:16] <pink_vampire> I need an irc app for my phone.
[01:06:51] <Wolf_> I have one on my phone, almost never use it
[02:05:45] <IchGucksLive> morning from Germany
[02:06:03] <IchGucksLive> today its off time as the cld has taken the education sector
[02:33:26] <Deejay> moin
[02:43:01] <IchGucksLive> Deejay: today all closed here as Grippe has taken the education sector completly down
[02:44:12] <IchGucksLive> im off
[02:44:18] <IchGucksLive> till evening
[02:48:08] <pink_vampire> how this weld work? https://www.youtube.com/watch?v=bx_F-ky5ZiE
[03:06:00] <minibnz> hey
[03:08:52] <pink_vampire> hi minibnz
[03:15:40] <pink_vampire> jog http://i.imgur.com/vS83CsU.png
[03:54:50] <pink_vampire> what do you think about that?
[03:54:51] <pink_vampire> http://www.ebay.com/itm/like/111932815843
[04:22:55] <minibnz> that picture of your tool travel is pretty crazy.. i have what 12 lines on mine :)
[04:24:03] <minibnz> i still dont trust my mill that much yet,, still havent made my tool platter, i got a quote the other day for the water cuttin $750au
[04:24:34] <minibnz> going to see what laser cutting costs would be. might be better finish
[04:45:36] <malcom2073> pink_vampire: I think that is a rip-off
[04:46:34] <pink_vampire> malcom2073: why?
[04:50:26] <XXCoder> biobreak
[04:52:31] <minibnz> $250 delivered might not be too bad if it wasnt made of wood...
[04:53:29] <minibnz> oh its acrylic thats a bit better..
[04:54:05] <XXCoder> whats it?
[04:54:32] <minibnz> an engraver frame with electronics and no motors.
[04:55:00] <XXCoder> plastic frame? weird. link?
[04:55:37] <minibnz> the one from pink to ebay.. it has alu extrusions and plastic plates that mount the motors..
[04:55:47] <minibnz> uses threaded rod for leadscrews
[04:56:56] <XXCoder> I come in recently
[04:56:59] <XXCoder> I cant see link
[04:57:14] <minibnz> http://www.ebay.com/itm/DIY-CNC-Engraver-Machine-PCB-Milling-Plastic-Wood-Carving-Printer-GRBL-No-Motors-/111932815843?_trksid=p2141725.m3641.l6368
[04:57:17] <minibnz> sorry
[04:57:38] <XXCoder> np
[04:57:40] <XXCoder> interesting'
[04:57:41] <minibnz> you would have more fun by adding another 200-300 and get a 40w laser engraver..
[04:58:29] <XXCoder> yea though no enclosure I'd avoid laser
[04:59:24] <XXCoder> I found similiar with steppers but $60 more shipping
[04:59:59] <minibnz> http://www.ebay.com/itm/321081980325?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT
[05:00:13] <minibnz> that would be sorta what i am talking about..
[05:00:35] <XXCoder> yeah the chinese laser box
[05:00:44] <minibnz> yup..
[05:01:09] <minibnz> when you have problems there will be plenty of 'motivate' people to help you..
[05:01:18] <minibnz> motivated..
[05:02:37] <XXCoder> guess so lol but I want cnc router functional first
[05:02:43] <XXCoder> Wolf_: you alive?
[05:07:27] <jthornton> morning
[05:07:55] <XXCoder> hey
[05:08:47] <jthornton> 27F this morning time to start burning wood again
[05:09:34] <jthornton> todays high 39F Saturday 70F
[05:15:05] <malcom2073> pink_vampire: It's flimsy, no spindle, and no motors.
[05:15:48] <XXCoder> flimsy is ok for light duty engraving, but having to buy spindle and motors seperately forget it
[05:16:05] <malcom2073> "Not suitable for engraving metal and hardwood etc." not even suitable for hardwood :)
[05:17:10] <Tom_itx> 20°F high: 47°
[05:19:16] <XXCoder> ya I would mill out metal parts and upgrade it
[05:19:19] <XXCoder> but why
[05:21:01] <malcom2073> It's not even acme thread, it's 1/4-20 bolts heh
[05:21:11] <malcom2073> And unsupported rails
[05:21:49] <malcom2073> You could build that, but with much thicker unsupported rails and acme screws for probably about the same price
[05:23:09] <XXCoder> yeah its just not suffecent
[05:45:52] <MacPhone> morning
[05:46:06] <XXCoder> hey maconish phone
[05:46:22] <MacPhone> how goes it?
[05:46:32] <XXCoder> reading today damages
[05:46:57] <MacPhone> how many?
[05:47:29] <XXCoder> lots
[05:47:51] <MacPhone> how many were your fault,
[05:47:54] <MacPhone> ?
[05:48:02] <XXCoder> like spicer saying nordstrom droppinf clothes line is direct attack on trump
[05:48:25] <MacPhone> probably
[05:48:40] <MacPhone> you mean the news not work
[05:48:42] <XXCoder> more likely, not selling
[05:49:39] <MacPhone> one thing i know from nord. is they are overpriced and if customers complain they kiss butt to keep them happy
[05:50:05] <XXCoder> oh not saying that company is perfection defined
[05:50:11] <XXCoder> I dont shop there
[05:50:17] <XXCoder> but they decided that without evidence
[05:51:09] <MacPhone> kind of convenient timing huh?
[05:51:19] <XXCoder> condiences happen
[05:52:07] <MacPhone> what else is new?
[05:52:26] <MacPhone> https://flic.kr/p/RLZhrt
[05:52:46] <XXCoder> high end!
[05:53:00] <MacPhone> lol. prototype
[05:53:04] <XXCoder> you 3d printed tha thing?
[05:53:13] <XXCoder> not holder but that green thingy
[05:53:16] <MacPhone> yeah. not a good setup
[05:53:44] <XXCoder> whats it for
[05:53:45] <MacPhone> but wanted to test before machining it
[05:54:05] <MacPhone> scroll back a few pics
[05:54:30] <MacPhone> its for the atc on my machine
[05:55:17] <XXCoder> so basically toolchanger tool holder
[05:55:23] <minibnz> MacPhone i have some of the same holders and i just got a quote to get all the parts cut in 6mm aluminium.. enough for 18 tools 750au
[05:55:25] <MacPhone> yea
[05:56:23] <MacPhone> not bad pricing
[05:56:54] <MacPhone> minibnz: u provide the cad
[05:57:32] <minibnz> yup in dxf
[05:57:54] <MacPhone> y not cut them yourself?
[05:58:15] <minibnz> it might have been the 2.5mm holes that have blown out the costs i haven't had a chance to find out if thats a second pass type thing..
[05:58:39] <minibnz> why not because that would take an age on my little seig X2
[05:59:11] <MacPhone> time is free and experience is priceless
[05:59:37] <minibnz> i already cut the prototypes out of plastic on my mill and i dont have it in me to do 18 wedges in 6mm alluminium
[06:00:41] <MacPhone> i got to make 20. so the plan is to cut one and make a custom fixture
[06:02:11] <MacPhone> your price seems fair considering setup and machine time plus materials
[06:02:39] <minibnz> i just spent 3 or 4 days drilling 24 holes into a 65mm x 65mm bar of aluminium.
[06:03:12] <minibnz> and if they do them they will be just as i draw them..
[06:03:20] <MacPhone> once u get the new motor, it should speed up
[06:03:27] <minibnz> none of this close enough, she'll be right mate stuff
[06:04:12] <minibnz> yeah it should.. should arrive friday according to the tracking.. but i am going to guns and roses on friday... yay fat axle
[06:04:39] <MacPhone> lol. i hear he is a basso now
[06:04:49] <minibnz> even if axle is crap slash and duff will put in a good showing
[06:05:16] <MacPhone> slash? i thought its bucket head now
[06:06:03] <minibnz> oh you might be right..
[06:06:30] <MacPhone> http://www.newgnr.com/newgnr.html
[06:06:46] <MacPhone> no duff no buckethead or slash
[06:07:11] <MacPhone> welcome to the jungle!
[06:08:41] <minibnz> http://www.couriermail.com.au/entertainment/confidential/guns-n-roses-brisbane-concert-original-lineup-hits-city-for-first-time/news-story/41d0349d201e3d893b70be19cd0c4247
[06:08:57] <minibnz> i begs to differ... WOoot Australia got something you dont :P
[06:09:09] <MacPhone> sounds fun. my roomie flew from sf to seattle on the 1st comeback. when axle didnt show for the first show a riot broke out
[06:09:27] <minibnz> hhehehehe
[06:09:50] <MacPhone> luckily he predicted that and got tix for the second show
[06:10:02] <minibnz> oh the recording has him missing half the words to mr brownstown.. i hope its just the shitty mic they used
[06:11:14] <MacPhone> awesome
[06:11:33] <MacPhone> the brown will put you down
[06:12:28] <MacPhone> i love a4d every song is drugs sex and rock and roll
[06:18:16] <MacPhone> ninibnz what kind of accuracy is your x2 producing?
[06:18:39] <XXCoder> ?
[06:20:27] <MacPhone> like you say cut 10mm what do u get?
[06:23:54] <minibnz> hmmm at the moment i dont think its quite right, i was playing with the speeds and dip switches on the drivers and stuffed up the decay settings when i upgraded a motor. i also have installed 16mm ball screws on X & Y and i get 10.00mm +/-0.01mm when it is set right
[06:25:29] <minibnz> before that i had bad backlash. 0.52mm on both X & Y i tried splitting the nuts that got it down to 0.3mm then i got ballscrews
[06:26:23] <minibnz> im just looking at my Z axis to see if i can remove some of the 1.83mm of backlash..
[06:26:50] <MacPhone> no luck with the backlash= in the ini?
[06:26:55] <minibnz> thats pretty bad but not too bad if your gas strut modification is working..
[06:28:04] <minibnz> yeah backlash in the INI is set up but i also have a head drop issue i think (seems to have fixed it self for the moment since i lifted the head and re-installed it all)
[06:28:38] <MacPhone> head drop on machine power down?
[06:28:51] <minibnz> my gas strut needs to be upsized since i added the power drawbar that weighs the head down a bit
[06:29:07] <MacPhone> ah
[06:29:36] <minibnz> head drop on moves. ie you tell it to move and it doesnt do it until all the back lash is taken up then it drops the backlash amount.
[06:29:56] <minibnz> so fixing the backlash fixes a few things..
[06:29:56] <MacPhone> ewe
[06:30:13] <minibnz> when you have a smallish cutter they just crumble..
[06:30:32] <MacPhone> the new motor is for z?
[06:31:04] <minibnz> yup and X & Y
[06:31:44] <minibnz> got all three... the one for z i am going to put a 4:1 gearbox on it.. that should get me from 700oz upto 1600oz
[06:31:44] <MacPhone> will u keep the strut w the new motors?
[06:31:49] <minibnz> yup
[06:32:25] <minibnz> otherwise i will have to keep power on it all the time and would probably reduce my feed speed abit
[06:32:54] <MacPhone> y not a brake?
[06:33:42] <minibnz> new strut is way easier to do.
[06:34:09] <minibnz> i dont have shop air.
[06:34:26] <minibnz> so air brake is out
[06:34:27] <MacPhone> power brake :)
[06:35:05] <MacPhone> mine has
[06:35:09] <minibnz> then i would probably need EVEN bigger steppers again..
[06:35:19] <MacPhone> timing is trickt
[06:36:02] <MacPhone> just 2 shafts and it attaches on the upper
[06:36:40] <minibnz> and that would mean loosing my handle on Z axis..
[06:36:41] <MacPhone> power on = release
[06:36:50] <minibnz> there are lots of reasons..
[06:37:51] <minibnz> and would require new motor again as i dont have dual shaft motors...
[06:39:43] <minibnz> for what i have spend and will still have to spend i could have bought a much much larger machine that was probably already CNC'd from the factory.. so i dont need a brake if i remove the backlash.. and a brake wont help when you are trying to cut a graduated depth slot it will jsut chatter the crap out of the mill and will produce a crapp cut.
[06:40:04] <minibnz> fixing the backlash is the way to go. a brake is not required.
[06:43:23] <minibnz> i know where its comming from im just not sure of the best ways to fix it..
[06:48:03] <minibnz> and i can't really think of using a ruby tip CMM probe on the Z axis with that much backlash it wont last very long at all.
[07:02:09] <archivist> most probes have decent over travel allowance
[07:03:38] <archivist> with that much backlash you get the results you deserve rather than a broken probe :)
[07:08:07] <MacPhone> archivist was looking at that probe interface patent you showed me. did you use a pwm on your setups?
[07:08:42] <archivist> why would I be using pwm on an input!
[07:08:56] <XXCoder> pwned
[07:09:02] <MacPhone> output
[07:09:12] <archivist> which output
[07:09:35] <MacPhone> the power out of the arduino
[07:10:09] <archivist> er what, you seem confused
[07:10:38] <archivist> there is no power out on the tart uino
[07:11:34] <MacPhone> im confused then
[07:11:57] <archivist> I am confused as to why you think there is a power out
[07:12:09] <MacPhone> well output
[07:12:21] <archivist> triggered?
[07:12:27] <archivist> plain level
[07:12:51] <archivist> at the moment was set up in the first instance to be direct wired
[07:13:29] <archivist> for opto/rf it should be modulated in some form
[07:13:36] <MacPhone> one of the things i read was that the trigger on the interface was pulsed to prevent arcing the contacts
[07:14:45] <MacPhone> so i figured pwm would accomplist this
[07:14:59] <minibnz> how much current arre you using to drive your probe?
[07:15:04] <archivist> we can use a level to drive the contact which is probably sensible to reduce battery use as well
[07:15:17] <archivist> 5ma at the moment
[07:16:16] <minibnz> cant see that being a problem really.. how much are they using to drive their probe?
[07:16:23] <archivist> contacts are a minefield, too little voltage/current and you dont "wet" the contact, too much and you burn
[07:16:52] <MacPhone> the service manual said 12ma 30v max
[07:17:11] <archivist> 5v 1k is what I started with
[07:17:25] <archivist> so not a lot
[07:17:57] <archivist> my TP2 probe was being a bugger on Renishaws own interface
[07:18:12] <minibnz> lower voltage youare going to be safe, i guess they use 12v due to connivence of what matches a PLC and what was avaialable in most machines
[07:18:31] <archivist> the LT02 has a multiplier to get some voltage
[07:19:33] <MacPhone> for calibration i was thinking a small digital scale
[07:20:00] <MacPhone> 15g is the low end
[07:21:40] <archivist> the current code has the scale built in
[07:22:07] <archivist> so it captures the force at the trigger time
[07:24:28] <MacPhone> cool
[07:24:32] <archivist> I use a 100g bar and an HX711 for the little probe, a 500g strain gauge bar is more sensible for brute force probes like the valeron
[07:31:22] <jdh> what are you using to read the HX711? arduino? canned library?
[07:36:47] <enleth> eh, I have to replace the V belt on the ORAC's spindle drivertrain with a toothed belt
[07:37:30] <enleth> I already managed to make it slip once on a test cut, enough to burn it a little
[07:37:53] <enleth> and with a VFD that has overload detection it doesn't even provide any safety
[07:39:28] <archivist> jdh, code is here http://www.archivist.info/cnc/Arduino_Probe_Interface/
[08:02:59] <jdh> thanks. looks like sane stuff I have been playing wuth.
[08:03:46] <jdh> my 5kg cells seems ok. 200kg one doesn't appear to ever change though
[08:05:26] <archivist> I have tried a 100kg on the hx711 seems to work
[08:13:14] <jdh> might have a bad $10 cell. or bad wiring
[08:15:31] <archivist> I have had an HX711 fail
[09:34:50] <jdh> I'm using the same on on both cells. same results with different hx711 though
[09:42:44] <archivist> a worker and a non worker or what
[10:53:15] <Loetmichel> meh. those chinese 800W watercooled spindles sure produce a lot of EMI... broke half a dozen mill bits today... couldnt determine why the router is losing steps... until i noticed the union nuit of the spindle side plug rattling. Turns out that the moment the extra copper weave shielding tube i put on the cable loses contact to the spindle and it is running all three steppers start to move
[10:53:15] <Loetmichel> in random directions :-(
[10:53:47] <_methods> ouch
[10:58:17] <CaptHindsight> that's a feature used to make cnc parts look hand crafted
[10:58:28] <MacGalempsy> :D
[11:00:05] <Loetmichel> the evil thing was taht the plug wasnt completely lose. only the casing wasnt securely connected because the union nut on it turned lose half a turn
[11:00:26] <SpeedEvil> ow
[11:00:58] <Loetmichel> i didnt notice it until i saw the nut move slightly and heard the steppers do some weired stuff at the same time
[11:01:35] <CaptHindsight> Loetmichel: there is a company in Germany that specializes in EMI shielding :)
[11:01:44] <Loetmichel> then it was clear where my "intermittent failure" was located
[11:02:10] <Loetmichel> CaptHindsight: thats the reason the cable to the spindle HAS a second copper shield in the first place
[11:02:58] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12506 <- delivered this way
[11:03:19] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12560 <- after a bit of "hands on" ;9
[11:03:20] <CaptHindsight> Loetmichel: do you think its EMI on the power or does it get to the Step Dir on the stepper drives?
[11:03:33] <Loetmichel> without that it was impossible to operate the router
[11:03:53] <Loetmichel> i assume it crosstalks to the LPT cable
[11:04:53] <CaptHindsight> well the Chinaco motto is: Remove all superfluous components until it stops working
[11:04:58] <Loetmichel> if you move the spindle cable closer to the LPT the "stepping around randomly" gets wors
[11:04:59] <Loetmichel> e
[11:06:10] <roycroft> that reminds me - i got a length of "cnc/automation motor" cable
[11:06:16] <CaptHindsight> every machine I get that has had some rewiring done has problems like yours
[11:06:16] <roycroft> it's 5 conductors, and shielded
[11:06:20] <roycroft> but it's fairly stiff
[11:06:34] <roycroft> fortunately it did not cost very much
[11:06:48] <roycroft> i guess i need to go look for some ultra flexible shieledec cable
[11:06:51] <roycroft> shielded
[11:07:08] <Loetmichel> roycroft: thankfully we have rolls of copper braid shielding tube here in various diameters
[11:07:14] <roycroft> the individual conductors seem fairly flexible, but the shield is not
[11:07:18] <CaptHindsight> roycroft: does the motor move or is it stationary?
[11:07:19] <roycroft> it's fairly stiff aluminium
[11:07:20] <Loetmichel> ... so upgrading that cable was quite easy ;)
[11:07:37] <roycroft> the motors will move
[11:07:42] <roycroft> it's a mill-drill
[11:07:49] <roycroft> well, the z motor will not move
[11:07:53] <roycroft> i can use this cable for that
[11:07:58] <roycroft> but x and y will move
[11:08:16] <roycroft> braided shielding would be the thing, i think
[11:08:58] <CaptHindsight> fine conductor
[11:10:02] <CaptHindsight> not this http://3.imimg.com/data3/PG/HN/MY-1226439/flexible-shielded-cable-250x250.jpg
[11:11:03] <CaptHindsight> roycroft: you want what Loetmichel shows in his pic
[11:11:46] <CaptHindsight> http://hollandshielding.com/content/4800/4800-Flexible-EMI-shielding-tube2.png
[11:12:24] <roycroft> i've used that kind of braid before
[11:12:33] <roycroft> when it's stainless steel it's a bitch to work with
[11:12:40] <roycroft> but it looks good and does a good job
[11:13:26] <CaptHindsight> http://www.digikey.com/en/product-highlight/a/alpha-wire/xtra-guard-flex-continuous-flex-control-cable
[11:13:28] <roycroft> i just got my motors yesterday
[11:13:37] <roycroft> i've a lot of work to do before they're ready to install
[11:15:38] <CaptHindsight> https://www.wirecare.com//category/braided-sleeving/metal-shielding/flexo-shield/fsn0.50sv-flexo-shield-1-2-tin-copper-emi-5-ft-cuts?gclid=CKPc8r27g9ICFQoQaQodnH4F2A
[11:16:03] <CaptHindsight> https://www.wirecare.com/category/braided-sleeving/metal-shielding/flexo-shield
[11:28:59] <roycroft> i don't think i can afford alpha wire
[11:29:14] <roycroft> $430.83 for a 100' length
[11:29:21] <roycroft> 100' being the shortest they sell at digi-key
[11:29:31] <roycroft> that's for 18ga 4 conductor
[11:30:55] <roycroft> an advantage of using a cable with integral shielding is that it would be easier to clean vs. a braided wire overwrap
[11:31:25] <Loetmichel> roycroft: thats why we use mostly tinned copper braid
[11:31:30] <Loetmichel> not stainless.
[11:31:41] <Loetmichel> thats a PITA to work with on the ends, too ;)
[11:32:44] <Loetmichel> we buy them by the 1000' spool... for a bit more than $430 ;)
[11:34:24] <Loetmichel> got a packet from china lately... with 4 1000ft spools in it, 8mm, 12mm and 20mm inner diameter. as it is flat when on the spool it was quite a small package... but the delivery guy looked like he was about to burst an artery ;)
[11:35:33] <Loetmichel> <- braced for impact and took it out of his hands with one hand an placed it "effortlessly" on the "wareneingang" counter... the look on his face ;)
[11:36:13] <Loetmichel> sometimes i tend to be an ass ;)
[11:39:26] <roycroft> i can use the stiff cable i got for bench testing
[11:39:33] <roycroft> so i have time to find something better
[11:39:43] <roycroft> i like the idea of tinned copper
[11:39:47] <roycroft> it works better than ss
[11:39:50] <roycroft> and it's easier to work with
[11:42:59] <Spida> Loetmichel: how heavy was that?
[11:43:20] <Loetmichel> maybe 50kg
[11:43:24] <Loetmichel> somewhere around that
[11:44:58] <CaptHindsight> roycroft: see the links for cuts of tin/copper ^^
[11:46:12] <CaptHindsight> the best deal on braided and jacketed cable is elevator/crane control cable
[12:07:24] <Spida> Loetmichel: I can understand the delivery guy :-)
[12:21:22] <Loetmichel> Spida: nonsese!... thats not even half my body weight. the delivery guy should man up a little. /s (on the other hand: the postage paid on the box said "heavy package, <21kg" while is was clearly more then double that :-)
[12:21:36] <Loetmichel> <=
[12:23:02] <Loetmichel> maybe that was one reason why i made it look lightweight. didnt want to pay additional postage ;)
[12:23:21] <Loetmichel> normally these deliverys come with a trucking service
[12:23:53] <Loetmichel> not with the normal (dhl)Postman ;)
[12:27:02] <pink_vampire> how do I remove the Vel: from the dro?
[12:32:03] <JT-Shopp> from the menu
[12:33:52] <IchGucksLive> hi
[12:35:28] <MacGalempsy> quick question for clarity on tool touchoffs. when the tool touches the tool setter and it is 1" above the table, to put it in the tool table at the right length is is just hit touchoff and say 1" with it set to tool table?
[12:36:11] <JT-Shop> for pre-settable tools if they are all touched off from the same point 0 is good
[12:36:33] <JT-Shop> just don't forget to touch off the material top lol
[12:36:49] <MacGalempsy> for sure!
[12:37:37] <IchGucksLive> and make shure you got a tool correct loadad at touchoff the part
[12:37:59] <MacGalempsy> I got the probe all dialed in, and have the length setup
[12:38:24] <IchGucksLive> i personly like a pointer tool
[12:38:40] <IchGucksLive> that is never changed to the TC for years
[12:38:41] <MacGalempsy> the nose of the table is -11.xxxx" from home
[12:39:11] <MacGalempsy> oops table to spindle nose
[12:39:31] <MacGalempsy> then touched off the table with the probe to get the probe length
[12:40:06] <MacGalempsy> is there a way to set the probe length so the calc doesnt have to be made every time the workpiece is touched off?
[12:41:13] <IchGucksLive> did you see under TOUCH off the TOOL TABLE
[12:41:41] <MacGalempsy> not at the machine at the moment
[12:42:02] <MacGalempsy> trying to get this hal setup for manual toolchange again...
[12:43:20] <IchGucksLive> did you delete the manual toolchange or only hide it
[12:43:20] <MacGalempsy> IchGucksLive: I assume from your question there is a probe length selection?
[12:43:30] <IchGucksLive> yes
[12:43:39] <IchGucksLive> http://linuxcnc.org/docs/2.5/html/gcode/tool_compensation.html
[12:43:42] <MacGalempsy> deleted it, but I have another file to get the removed code from
[12:44:53] <MacGalempsy> so you use T1 as your probe?
[12:45:14] <IchGucksLive> here its the last in the pocket T32
[12:45:36] <MacGalempsy> ok. thank you.
[12:45:43] <IchGucksLive> on mashines with REAL mesurment its outside the TC
[12:45:56] <IchGucksLive> as it has Elek connection
[12:46:48] <IchGucksLive> this mashines then have a t=
[12:46:52] <IchGucksLive> T0
[12:47:26] <IchGucksLive> with rubinum to set the coordinates
[13:29:25] <IchGucksLive> GN8
[13:46:28] <roycroft> belden make some "vfd" cables
[13:46:44] <roycroft> i just ordered a sample kit of all three of their vfd cable types
[14:04:54] <terry_> Hi all
[14:05:59] <terry_> Lost power while cutting. Upon restarting things, found .var file all zero save for 5220 which is 1.
[14:06:37] <terry_> No G42 seems to not work, cuts too big.
[14:06:51] <terry_> No = Now, typo
[14:06:54] <roycroft> restore from backup?
[14:07:17] <terry_> Ya, backup ... ah ...
[14:07:54] <terry_> All else seems fine, just cutter comp seem wrong. Any ideas?
[14:08:15] <roycroft> not myself
[14:08:18] <roycroft> others might
[14:08:19] <gregcnc> tool table has diameters?
[14:08:38] <terry_> Yes, I checked the tool table, looks fine.
[14:08:58] <JT-Shop> a backup of the var file should be there
[14:09:36] <terry_> Yes, but it was identical to the .var file, with the same time stamp.
[14:09:51] <JT-Shop> yikes
[14:11:39] <terry_> My guess is that the .var file was corrupt, and LinuxCNC over wrote it upon startup? and created a new backup also? Sound correct?
[14:11:51] <JT-Shop> prob yea
[14:12:20] <JT-Shop> G42 works off the tool table
[14:12:31] <cradek> please say more about "G42 cuts too big"
[14:12:51] <terry_> I also tried G42.1 with the same D as the table, same thing.
[14:13:01] <cradek> what thing?
[14:13:06] <Jymmm> I HIGHLY recommend that people get i the habit of 'cp filename filename-201702091142' BEFORE editing any file. You can always delete old files if needed
[14:13:14] <terry_> Island was too big.
[14:13:32] <terry_> It is cutting around the outside of an island.
[14:13:43] <gregcnc> too big by a cutter diameter?
[14:14:13] <terry_> No, cutter is 0.50008 in.
[14:14:16] <cradek> which way around the island? what are the sizes? tell us what you're seeing
[14:14:36] <terry_> Island is too big across by ~0.020 in.
[14:15:10] <terry_> or 0.010 on a side.
[14:15:45] <terry_> Cut CCW with G42.
[14:16:15] <cradek> this isn't caused by a power failure. check your tool diameter and tool table and gcode again?
[14:16:18] <Spida> is a nickel or a zinc based galvanization on steel expected to last longer in an acid environment (humid air with high carbon dioxide concentration)?
[14:16:31] <gregcnc> well I guess the first question is, has this program run correctly before?
[14:17:20] <terry_> Just wrote it before the power failure.
[14:17:32] <terry_> Short, about 10 lines.
[14:18:04] <gregcnc> OK, so does cutter comp normally work?
[14:18:12] <terry_> Normally
[14:19:57] <gregcnc> seems odd. i don't know
[14:20:01] <terry_> I will write a new program, with just one pass along one side, and see what happens.
[14:20:11] <cradek> forget the power failure and debug in the normal way. did someone load a resharpened end mill?
[14:20:38] <terry_> No, only I use this machine.
[14:20:58] <terry_> Same tool I usually use.
[14:21:16] <terry_> Home shop.
[14:22:39] <Jymmm> I feel for ya, had a power outage that totally destroyed one of my VM's. I'm still working on damage control for it for the last 2 days, and I've run out of diskspace
[14:24:21] <Jymmm> Do you know how hard it is to find and remove 20GB and larger files just to you have enough room to repair the damage?!
[14:24:59] <Jymmm> ...and the time it takes just to move/copy them
[14:28:06] <sync_> that is what 10G is for
[14:29:17] <Jymmm> sync_: You mean 10T?
[14:29:23] <Jymmm> or 10P
[14:29:35] <Jymmm> oh 10Gig-E ?
[14:29:38] <sync_> yes
[14:29:58] <Jymmm> sync_: this is all at the fs level, not even the lan
[14:30:03] <sync_> oh well
[14:30:09] <Jymmm> so sata speeds
[14:30:10] <sync_> then speed should not be too much of an issue
[14:30:36] <Jymmm> sync_: some of the VM's are 6-GB each, plus snapshots, plus clones.
[14:30:44] <Jymmm> 60GB*
[14:30:46] <sync_> yeah, although sata is kinda slow, you notice the difference to pcie pretty well
[14:33:44] <Jymmm> sync_: the power outage essencially created bad sectors on the vdisk at the VM level, so basically I'm dealing with a failing hdd. It crashed vbox during file recovery and destoryed another VM, luckily I work off copies and not the original VM/VDISK, so later rinse repeat, clone and clone again.
[14:34:03] <Jymmm> s/later/lather/
[14:34:39] <Jymmm> all without one error message.
[14:34:51] <Jymmm> If this was bare metal, I'd be screwed.
[14:34:52] <sync_> nice
[14:35:58] <Jymmm> So the lesson for today boys and girls is to CLONE your VM's periodically, not just snapshots
[14:37:53] <JT-Shop> dang new M325 Logitech mouse is super sensitive
[14:59:19] <terry_> OK, wrote a supper simple single strait cut program, same. Tried a different tool number/cutter, same.
[14:59:42] <terry_> Guess I'll try a reinstall...
[15:03:45] <terry_> Thanks everyone.
[15:06:04] <JT-Shop> do you have an offset left over
[15:50:23] <Tom_itx> JT-Shop, you can't adjust the mouse sensitivity?
[15:51:07] <JT-Shop> tried
[15:52:02] <JT-Shop> tried being nice to it then got mad and was very ugly to it but it is still sensitive and started to cry so I threw it out in the woods
[16:00:41] <roycroft> so now you've left it to be eaten by a cat
[16:00:59] <roycroft> it's really going to cry now
[16:01:01] <roycroft> for a few seconds
[16:02:28] <JT-Shop> maybe I should hang it just outside the cats reach by it's tail...
[16:03:57] <Tom_itx> windows or linux?
[16:04:29] <JT-Shop> linux
[16:05:08] <Tom_itx> they don't make software for linux for it?
[16:05:26] <Tom_itx> i use it on my trackball
[16:05:42] <Tom_itx> but it's windows
[16:08:40] <JT-Shop> hmm if I swap it with the windows pc in the beer cave with a dead kb then I'd have two mice the same color on my desktop lol
[16:08:47] <Tom_L> https://mikebeach.org/2010/06/27/logitech-devices-on-ubuntu-linux-and-others/
[16:09:36] <JT-Shop> can you zip up the #linuxcnc-devel for 2016 and 2017 so I can d/l in the am?
[16:09:43] <JT-Shop> I need to search it for some info
[16:10:04] <Tom_itx> yeah, it will be the old logs though
[16:10:14] <JT-Shop> that's ok
[16:10:16] <Tom_itx> the new server hasn't run in a while
[16:10:50] <roycroft> is someone actively maintaining/developing halcmd?
[16:11:23] <roycroft> er, halrun
[16:11:35] <roycroft> which gives a halcmd prompt :)
[16:11:35] <JT-Shop> is it broke?
[16:11:44] <roycroft> i have a feature request
[16:12:02] <Tom_itx> file a report for it
[16:12:03] <roycroft> but if nobody is working on it i won't bother
[16:12:09] <roycroft> where's a good place for that?
[16:12:27] <JT-Shop> https://github.com/LinuxCNC/linuxcnc/issues
[16:12:30] <roycroft> thanks
[16:12:31] <Tom_itx> the forum i suppose. i've never done it
[16:12:42] <JT-Shop> not the forum
[16:13:06] <Tom_itx> ^^
[16:13:41] <roycroft> i'll report it to not the forum
[16:14:22] <JT-Shop> apply the label enhancement to the issue
[16:14:22] <roycroft> i wouldn't exactly call it an issue, but that's probably where it fits best
[16:14:30] <roycroft> ok, that makes sense
[16:15:00] <JT-Shop> see this one https://github.com/LinuxCNC/linuxcnc/issues/216
[16:17:37] <Tom_itx> you want all of 2016 and up to current of 2017 ?
[16:17:38] <roycroft> at the moment i'm fighting with github to register there
[16:18:15] <Tom_itx> JT-Shop, is rar ok?
[16:18:17] <roycroft> it's not a big deal, so if github doesn't like me i'll not bother
[16:18:36] <roycroft> rar is for pr0n and war3z! :)
[16:19:07] <roycroft> are you guys trading pictures of naked machinery?
[16:21:34] <XXCoder> rule 34
[16:23:27] <JT-Shop> Tom_itx: yea 2016 and 2017 should do... zip is better I don't think I have winrar anymore
[16:23:38] <XXCoder> JT-Shop: 7zip
[16:23:47] <XXCoder> it supports rar and many other formats
[16:23:53] <JT-Shop> is that linux?
[16:23:55] <Tom_itx> ok lemme redo it
[16:24:07] <XXCoder> windows actually
[16:24:19] <XXCoder> I saw you say winrar then I figured you meant for windows heh
[16:25:02] <XXCoder> http://www.7-zip.org/
[16:25:09] <Tom_itx> i have it already
[16:25:42] <JT-Shop> winrar is the only one I've used in the past years ago for something I forget
[16:30:14] <Deejay> gn8
[16:41:51] <R2E4> Hi guys and girls.......... motion-spindle-on we get that when we get and SXXX in GCODE?
[16:42:47] <JT-Shop> Snnn and M3 or M4
[16:42:52] <Tom_itx> when the spindle is on
[16:47:42] <R2E4> ok thanks
[16:49:49] <R2E4_bevins> I dont need all the pid stuff when using 0-10 on a 7i77? I can just remove it and just dont loadrt pid.s ?
[16:51:51] <JT-Shop> if your not using pid don't load it
[16:51:59] <pcw_mesa> For spindle without feedback you can just connect spindle speed out to the analog out
[16:53:10] <pcw_mesa> (with the analog out scaled in RPM so maxscale = 10000 or some such)
[16:53:58] <pcw_mesa> (maxscale set to whatever the spindle RPM is at 10V)
[16:54:47] <pcw_mesa> you may need the ABS component if the spindle is reversable
[16:54:55] <R2E4_bevins> ok cool, thanks, working on that now.
[16:55:09] * JT-Shop takes notes :)
[16:55:14] <R2E4_bevins> It is but I am not going to use the reverse, its a large wood router.
[16:56:37] <R2E4_bevins> I dont think I will have a problem with it. we'll see.
[16:56:49] <JT-Shop> that would be wild to run the router in reverse
[16:57:24] <andypugh> I have decided to add that pretty probe screen to my mill. But I can’t find it.
[16:57:36] <andypugh> Anyone recall a good search term to find it with?
[16:57:39] <R2E4_bevins> I got the analog outs but I have a question, setting the sserial_port=200xxx gave me the 4 analog outs but so did 100xxx.
[16:57:55] <R2E4_bevins> Whats the diff and where can I find that info? I looked earlier and couldnt find it.
[16:59:01] <andypugh> R2E4_bevins: The serial modes are described in the 7i77(?) manual under “process data modes” or something like that.
[16:59:11] <R2E4_bevins> JT-Shop: this machine has 33 drill bits with two motors all connected together. one turns they all turn but every other one turns in reverse.
[16:59:35] <JT-Shop> wow what does it make?
[16:59:47] <R2E4_bevins> one motor turns it one way and the other turns it the other way.
[16:59:57] <JT-Shop> are they geared together?
[17:00:16] <enleth> interesting - the ORAC has two ballnuts on the Z screw, back to back on the carriage
[17:00:24] <R2E4_bevins> yes, and you can drop one or all of the bits
[17:01:00] <R2E4_bevins> They drop via air valves.
[17:01:00] <andypugh> enleth: That’s quite a common way to remove backlash. In effect one nut handles left and the other handles right.
[17:02:15] <Roguish> andypugh: forum search for 'probe_screen.py'
[17:03:48] <skunkworks_> andypugh, http://forum.linuxcnc.org/49-basic-configuration/29187-work-with-probe?limitstart=0
[17:03:50] <R2E4_bevins> AH, mode 2 is what I need.
[17:04:22] <Roguish> skunkworks: andypugh: yeah, that's the one.
[17:18:59] <enleth> andypugh: makes sense. now I need to figure out if it's feasible to replace their permanent coupling to the carriage with a bearing, a friction brake and a right angle gear for a handwheel
[17:19:28] <enleth> it might very well be a dumb idea but I'd still like to make it an optionally-manual machine
[17:19:45] <enleth> for the heck of it, if nothing else
[17:21:12] <sync_> put a servo motor in for the handwheel
[17:21:27] <sync_> and do torque feedback for the feeling
[17:21:35] <enleth> nah, I'd like to play with a mechanical solution
[17:22:15] <enleth> I'm really fond of the mechanical handwheels on the CNC mill
[17:23:07] <sync_> it should feel the same
[17:23:25] <andypugh> enleth: I just put a pair of jogwheels on the saddle of my Holbrook. No feel, but it works well.
[17:24:22] <andypugh> Like this: https://goo.gl/photos/6LeNjPSYykQ4bQCQ6
[17:24:57] <enleth> andypugh: I know, I've seen the build photos some time ago
[17:25:58] <enleth> I can see the point of it, I'm just up for a challenge of cramming a brake/transmission/nut coupling contraption into the apron
[17:41:09] <andypugh> No, Icewasel, I do not want you to correct “linuxcnc,org” to “linuxcnc,org.com”
[17:41:43] <roycroft> i've found i need to disable any auto-correction "features" in any software i use
[17:45:34] <JT-Shop> what's an Icewasel?
[17:46:10] <roycroft> it's an open-source web browser that's firefox-like
[17:46:36] <roycroft> i believe it's based on mozilla code
[17:51:08] <JT-Shop> oh iceweasel default in debian I think
[17:52:08] <JT-Shop> yea I didn't like it at all
[17:52:38] <roycroft> i don't like firefox
[17:52:40] <roycroft> it's butt-ugly
[17:52:52] <roycroft> browsing is challenging for me these days
[17:52:55] <roycroft> i dislike firefox
[17:52:57] <roycroft> i shun anything google
[17:53:05] <roycroft> and safari is generally fairly broken
[17:53:11] <roycroft> i use tor browser for a lot of stuff though
[17:53:15] <roycroft> it really cuts down on spam
[17:53:29] <R2E4_bevins> yes but ice-weasel I find slow
[17:53:47] <roycroft> but it's a fairly basic browser, and by its very nature, it loads things very slowly, since everything goes through multiple proxies
[17:53:49] <R2E4_bevins> I use it, but it seems slow and sluggish to me, maybe it my computer ....
[17:55:00] <R2E4_bevins> spindle is wired up in HAL, and set in ini and Linuxcnc starts. Thats good news..... Time to adapth the hardware.
[17:55:23] * JT-Shop starts windoze again after a crash
[17:57:10] <JT-Shop> R2E4_bevins: making progress!
[17:57:11] <andypugh> JT-Shop: Slow learner?
[17:57:47] <JT-Shop> must be I give up trying to repair the faces on that imported part
[17:57:48] <andypugh> (That comment would have made more sense prior to JTs last message)
[17:59:50] <JT-Shop> crap can't even open the part now...
[18:00:00] <JT-Shop> says it's in use by another SW session
[18:00:26] * JT-Shop gives up on that and makes a repair part for the cannon
[18:01:49] <Tom_itx> JT-Shop, was it a stl file?
[18:01:49] <enleth> jeez, they put the coupling blocks between the nuts on the ballscrew and it doesn't have a cutout/slot connecting the screw through-hole to the side
[18:02:02] <enleth> one of the nuts has to be taken completely off to remove the coupling
[18:04:40] <andypugh> enleth: Are you sure?
[18:05:17] <andypugh> I seem to recall being slightly confused by the double-ballnut I have on my lathe.
[18:06:38] <andypugh> Tiny pic: http://images.machinedesign.com/images/archive/ballscrew1jpg_00000038677.jpg
[18:07:32] <andypugh> The non-flanged unit just screws down the screw hard against the collar, and the collar thickness is chosen so that the slots align. and that is actually all there is to it.
[18:08:43] <JT-Shop> Tom_itx: no a stp file
[18:09:05] <enleth> andypugh: http://i.imgur.com/7UfAOay.jpg
[18:09:39] <andypugh> OK, that’s different
[18:09:41] <enleth> the block in the middle has two screw holes to attach it to an adapter plate on the carriage and a through hole for the screw
[18:11:53] <JT-Shop> crap can't open the file, delete or rename it I hate windows
[18:20:05] <enleth> what I intend to do is: 1. remove that block from the screw, bore the hole somewhat bigger, split the whole thing lengthwise on one side, add a clamping screw that accepts a lever; 2. machine a two-flanged sleeve that goes onto the screw between the nuts, has two thrust bearings on the inner sides of the flanges and can be adjusted to clamp onto the block with the bearings; 3. slap a bevel gear on one of
[18:20:11] <enleth> the nuts; 4. add a handwheel with a second bevel gear and a lever for the block clamping screw on the apron cover
[18:21:13] <DaViruz> pcw_mesa: the 7i76+g540-firmware you made worked a treat (once i figured out 1ns step pulse length is a bit on the short side), thanks a lot!
[18:21:23] <enleth> or something to the tune of the above, obviously 90% of the details are going to turn out differently
[18:22:34] <pcw_mesa> DaViruz: yeah the G540 specs (AFAICT) are for 5V signals, 3.3V needs longer step times
[18:23:54] <pcw_mesa> glad it worked (just Frankensteined a couple configs together)
[18:23:55] <DaViruz> i grabbed the hostmot2 stepgen-stuff from some other hal file, and i didn't notice they had fishy pulse length settings
[18:24:56] <pcw_mesa> 1 ns probably gets rounded up to 30 ns but still a bit short
[18:25:46] <DaViruz> actually i didn't figure it out until i found a forum post by someone who had made the exact same error, where you replied with the correct answer :)
[18:28:55] <DaViruz> now i just have to figure out why my accel is way low and why changing it's values doesn't seem to have any effect..
[18:46:56] <Tom_itx> JT-Shop, map a drive and rename it from linux
[19:12:29] <R2E4_bevins> Is there a way I can use the trailing edge and rising edge to oneshot a relay for each on motion.spindle-on?
[19:13:40] <R2E4_bevins> I need a pulse for start inverter, and a different pulse to stop inverter
[19:14:44] <Tom_itx> did you read oneshot docs?
[19:14:50] <Tom_itx> it allows rising and falling edges
[19:15:02] <Tom_itx> and regriggerable
[19:15:08] <Tom_itx> retriggerable*
[19:15:46] <CaptHindsight> multivibrator
[19:15:56] <Tom_itx> if you need 2 inputs, use an or
[19:15:59] <Tom_itx> to it
[19:16:51] <Tom_itx> or set them both to true and it should trigger on rising and falling edges
[19:17:16] <Tom_itx> (it doesn't say you can't)
[19:22:39] <MacGalempsy> can I get a little insight? the tool lengths are all set from the table height. the touchprobe is T1. touchoff from the x/y worked fine. as for touching off the z, off the top of the workpiece went good. 0.2" above the workpiece. then did a t2 m6. z0 f10. but the z is returning to the height of the probe, not T2. what did I do wrong?
[19:23:22] <R2E4_bevins> I used oneshot earlier in the startup procedure. I will check again.
[19:24:51] <R2E4_bevins> I need when motion.spindle-on goes true to oneshot a relay, then when motion.spindle-on goes false to oneshot another relay.
[19:28:28] <Tom_itx> so set up 2 oneshots to the same signal
[19:28:40] <Tom_itx> trigger one on rising edge. trigger the other one on falling edge
[19:28:46] <Tom_itx> done deal
[19:41:44] <CaptHindsight> whoohoo, got lucky today at Shars, 2,3,4 blocks are 2,3 and 4"! And the V-blocks are matched
[19:41:59] <Tom_itx> hah nice
[19:42:15] <Tom_itx> don't recall using 2,3,4 blocks
[19:42:41] <CaptHindsight> they said they had to change to a few Taiwanese suppliers to get better QC
[19:42:46] <Tom_itx> always stacked 1,2,3 blocks
[19:43:17] <Tom_itx> bet they wouldn't pass cert at a gage lab
[19:43:44] <CaptHindsight> depends on whos spec :)
[19:44:39] <CaptHindsight> I noticed that several of their "high accuracy" indicators have a resolution far under their accuracy
[19:44:55] <CaptHindsight> so any readings on the far right are meaningless
[19:48:32] <CaptHindsight> and FYI about Shars, any KUS's that start with 415 or 416 end mills are not stocked at Shars, they are from a 3rd party
[19:48:48] <CaptHindsight> KUS's / SKU's
[19:50:33] <CaptHindsight> and all US made
[19:50:55] <Tom_itx> gonna see more of that in the days to come
[20:03:09] <t12_> dir
[20:03:10] <t12_> er
[20:03:14] <t12> wrong window!
[20:10:24] <CaptHindsight> gone are the days of going to the hardware store and looking at the tap drill chart
[20:10:41] <Tom_itx> i keep one on my phone
[20:11:02] <CaptHindsight> I asked the other day and they looked at me like I was asking for dinosaur teeth polishers
[20:13:01] <CaptHindsight> I need a F
[20:13:34] <Tom_itx> it comes in a 115 piece set
[20:14:05] <CaptHindsight> of course
[20:14:06] <Tom_itx> .2570
[20:14:19] <_methods> heh i have tap drill chart on my door
[20:14:24] <Tom_itx> 1/4" would likely work
[20:14:35] <Tom_itx> same here
[20:14:37] <CaptHindsight> yeah just wiggle as you drill
[20:14:41] <Tom_itx> several
[20:14:55] <CaptHindsight> 5/16-18
[20:14:57] <_methods> constantly use that thing
[20:15:46] <Tom_itx> clearance is D tap is F
[20:16:31] <CaptHindsight> have to get some extra taps tonight
[20:17:05] <Tom_itx> manual or cnc?
[20:17:06] <CaptHindsight> because the one in that size will undoubtedly break in the last hole or as soon as I get tired :)
[20:17:16] <CaptHindsight> whichever comes first
[20:17:30] <CaptHindsight> manual
[20:17:32] <Tom_itx> high helix work better on cnc
[20:17:51] <CaptHindsight> it's for the ends of t-slot
[20:18:04] <CaptHindsight> I need to make a cnc t-slot end tapper tool
[20:18:51] <CaptHindsight> or drill a hole 8 ft deep through the table and floor of an existing cnc
[20:19:00] <CaptHindsight> or get a horizontal mill
[20:19:25] <CaptHindsight> that might be a good idea, they always sell for cheap
[20:19:34] <Tom_itx> are the offsets all the same for them?
[20:19:52] <CaptHindsight> define offset
[20:19:54] <Tom_itx> just make a jig for hand tapping
[20:20:00] <Tom_itx> same location each time
[20:20:18] <Tom_itx> L shape aluminum with a hole in it
[20:20:38] <CaptHindsight> had tapping takes to long
[20:20:51] <Tom_itx> use a hand drill with the guide and some tap honey
[20:21:23] <CaptHindsight> nah, tapping head on a horizontal mill
[20:21:27] <Tom_itx> i use a pneumatic drill for that sometimes
[20:21:51] <CaptHindsight> has to be fast and foolproof
[20:22:56] <Tom_itx> one place i worked had a room full of special 2nd op equipment for such things
[20:23:10] <Tom_itx> one, all it did was thread the end of wires
[20:24:00] <CaptHindsight> off to the store b4 they close
[20:24:12] <Tom_itx> sounds like something that loading the material will take longer than the actual process
[21:50:15] <R2E4_bevins> Tom_itx: cant connect the same signal to two oneshot subs
[22:28:40] <CaptHindsight> hmm all my machines all lean NE. I wonder if its magnetism?
[22:42:19] <os1r1s> CaptHindsight Do you have any idea what brand/make these switches are? http://www.automationtechnologiesinc.com/wp-content/uploads/2016/08/G0704B.jpg
[22:52:15] <Tom_itx> R2E4_bevins, it seems odd that you can't do that
[22:52:35] <Tom_itx> 2 instances configured differently
[22:52:50] <Tom_itx> connected to different outputs
[22:59:35] <MacPhone> anyone still makin chips?
[23:10:09] <CaptHindsight> still werkin but not makin chips
[23:13:03] <CaptHindsight> os1r1s: since it's on the AT website I'd reckin some Chinaco knockoff
[23:16:44] <CaptHindsight> http://www.automationtechnologiesinc.com/products-page/featured-cnc-products/grizzly-g0704-cnc-milldrill-w-enclosure it's on the Grizzly mill/drill/eggbeater
[23:17:52] <CaptHindsight> hah "By adding Double Ballnuts to our ball screws we have doubled the accuracy to the kits that are now available today. "
[23:18:16] <CaptHindsight> by reassembling them properly we improved them 10 fold
[23:18:51] <CaptHindsight> +/- 0.005" Accuracy
[23:18:54] <CaptHindsight> ouch
[23:22:06] <roycroft> that machine should be able to hold better than 0.005"
[23:32:54] <CaptHindsight> it doesn't mention repeatability so maybe it's not square
[23:33:13] <CaptHindsight> or the way just have too much runout even when new
[23:33:18] <CaptHindsight> way/ways
[23:33:30] <roycroft> they should fix them then
[23:33:47] <CaptHindsight> does the column flex when at full height?
[23:33:53] <roycroft> i don't have that machine
[23:34:03] <CaptHindsight> yeah, it just looks careless or lazy to me
[23:34:29] <roycroft> i have a g0463
[23:34:56] <roycroft> which a lot of folks who have the g0704 say is a better machine
[23:35:09] <roycroft> but i think the two are pretty similar
[23:35:26] <CaptHindsight> http://www.grizzly.com/products/Mill-Drill/G0463
[23:35:44] <roycroft> yes, that is what i have
[23:36:22] <roycroft> mine is actually a lot heavier than the g0704
[23:38:04] <CaptHindsight> http://www.grizzly.com/products/Drill-Mill-with-Stand/G0704
[23:38:35] <roycroft> perhaps it's telling that the g0463 is a mill-drill and the g0704 is a drill-mill
[23:39:06] <R2E4_bevins> Tom_itx: I am probably doing it wrong.... I will do it in classic ladder.
[23:39:40] <R2E4_bevins> trying to get the 0-10 out the 7i77 card with no luck either....lol
