[00:00:18] <Cromaglious_> oh doh... think I fingured it out.. I might have a solder bridge on the top of the boards where I switched the green screw connections to plugs
[00:02:07] <Cromaglious_> I test it tomorrow when I have more light
[00:05:21] <pink_vampire> how it looks?
[00:05:54] <pink_vampire> you don't have a good light?
[00:06:48] <Cromaglious_> it's on the back porch... I don't have good light out here yet..
[00:15:36] <pink_vampire> you can't move it?
[00:17:10] <Cromaglious_> don't feel it moving it
[00:18:04] <Cromaglious_> all the flat surfaces in the house are covered with sewing... We have a show going up next week
[00:18:46] <MacGalempsy> what kind of sewing projects?
[00:20:08] <Cromaglious_> lot of pumpkin pants, some doublets, shirts, shirt repairs, I think one dress still All very Shakespearean
[00:20:27] <Cromaglious_> we're part of Shakespeareinthevines.org
[00:23:51] <Cromaglious_> This spring I put a Consew CS1001 servo motor on the Juki DLL-5550 industrial sewing machine and rigged the needle positioner. I also add some 12v LED's to light up around the needle.
[00:24:01] <TurBoss1> hi
[00:25:36] <Cromaglious_> hiya
[00:37:46] <TurBoss1> I'm stuck configuring external e-stop using latch
[00:38:08] <TurBoss1> I'm using this as reference http://gnipsel.com/linuxcnc/configs/external-estop.html
[00:38:54] <TurBoss1> http://dpaste.com/1AGMVY9 this is my hal file
[00:40:25] * TurBoss1 reboots
[00:40:40] <XXCoder> okay lol
[00:41:54] <Cromaglious_> it'll give me time to load those pages
[00:42:25] * TurBoss1 is back
[00:45:26] <Cromaglious_> sheeshz... I haven't looked at Hal in ages
[00:47:00] <MacGalempsy> I know why there is a lack of tutorials, because everytime someone finally gets their machine done, they want to forget all about it
[00:47:13] <XXCoder> lol
[00:47:26] <TurBoss1> XD
[00:47:47] <TurBoss1> I'm using master branch
[00:48:00] <TurBoss1> because I need joints
[00:51:22] <TurBoss1> http://dpaste.com/2KFXEBY < the importn bits
[00:56:43] <Cromaglious_> I was looking through Smoothieware source... cpp my eyes hurt
[00:57:43] <TurBoss1> omg my parport is not working
[00:58:13] <MacGalempsy> that last bit doesnt show it connected
[00:58:34] <MacGalempsy> TurBoss1: add the component
[00:58:39] <Cromaglious_> is it putting out enough power to work?
[00:58:57] <Cromaglious_> or is it dead, or switched to the wrong address?
[00:59:15] <TurBoss1> MacGalempsy: how?
[01:01:12] <MacGalempsy> http://linuxcnc.org/docs/2.4/html/hal_parallel_port.html
[01:04:56] <TurBoss1> parport switche address
[01:05:04] <TurBoss1> is loaded
[01:05:09] <TurBoss1> checking
[01:23:28] <TurBoss1> Ok prport is working again
[01:23:38] <TurBoss1> but latch stil not
[01:25:17] <MacGalempsy> are you using halmeter to see if the pins are connected?
[01:25:59] <MacGalempsy> do you have any power to the pin signal?
[01:26:36] <MacGalempsy> like perhaps a 3 or 5v?
[01:27:09] <TurBoss1> yep halmeter show pin 10 on parport 1 working
[01:27:33] <MacGalempsy> so you hit the button and the halpin goes true?
[01:27:42] <TurBoss1> yes
[01:28:07] <TurBoss1> bu the e-stop doesn't work
[01:28:10] <MacGalempsy> ok so the signal is good. did you check the other 3 signals?
[01:28:19] <MacGalempsy> loopout, loopin, reset
[01:28:24] <TurBoss1> checkin
[01:29:31] <TurBoss1> no changes on hoose 3
[01:29:46] <TurBoss1> thoose*
[01:30:23] <Rayhk> 请问一个电子邮件地址可以注册几个irc账号?
[01:31:04] <LeelooMinai> Rayhk: I think about 25 mil
[01:31:23] <Rayhk> 谢谢。
[01:31:29] <LeelooMinai> Right
[01:31:45] <MacGalempsy> it looks like there are more than just 4 pins on the latch component
[01:32:01] <MacGalempsy> did you read the component page in the manual?
[01:32:15] <TurBoss1> estop-latch.0.fault.in opin toggles
[01:32:40] <TurBoss1> not much
[01:33:05] <MacGalempsy> i use the estop built into the mesa card
[01:33:13] <MacGalempsy> so you will need to read up
[01:33:25] <TurBoss1> ok
[01:33:28] <MacGalempsy> it looks pretty simple, but you may need to manually set some parameters
[01:34:08] <MacGalempsy> The state changes from "Faulted" to "OK" when all these conditions are true:
[01:34:08] <MacGalempsy>
[01:34:08] <MacGalempsy> fault-in is false
[01:34:09] <MacGalempsy>
[01:34:09] <MacGalempsy> ok-in is true
[01:34:09] <MacGalempsy>
[01:34:11] <MacGalempsy> reset changes from false to true
[01:36:34] <MacGalempsy> once you get the pins to flash correctly, you should be able to link the signal of ok-out to motion.enable
[01:36:52] <TurBoss1> hmmmm ok
[01:36:58] <MacGalempsy> then if estop goes false, then enable is false
[01:37:12] <MacGalempsy> motion.enable is in the axis component
[01:37:18] <MacGalempsy> http://linuxcnc.org/docs/html/man/man9/axis.9.html
[01:38:19] <MacGalempsy> it is late, so it is time to go to bed. good luck!
[01:38:24] <TurBoss1> ok wil continue later i had to go work
[01:38:33] <TurBoss1> thank yo so much
[01:38:37] <MacGalempsy> no problem
[01:38:38] <TurBoss1> *you
[01:38:42] <TurBoss1> xD
[01:41:31] <XXCoder> https://www.youtube.com/watch?v=yxyCLoYfexo
[01:41:36] <XXCoder> still waiting for that! heh
[01:53:11] <LeelooMinai> I like how you can just grab any McMaster part from inside Fusion360
[01:55:39] <LeelooMinai> Improved my hinge: http://i.imgur.com/kSl6Voo.png
[01:56:08] <LeelooMinai> I have scate bearings so I will put one there + washer + 8mm hex screw and this big plate
[01:56:12] <XXCoder> oh yeah looks nicely stronger
[01:56:20] <XXCoder> may I suggest one minor change
[01:56:28] <LeelooMinai> Sure
[01:56:29] <XXCoder> larger hidge center rod
[01:56:47] <XXCoder> its focus of force after all
[01:56:57] <LeelooMinai> Rod?
[01:57:19] <LeelooMinai> That scew there will be the pivot - it's huge: 8mm
[01:57:37] <XXCoder> I'd suggest even larger but 8mm is pretty strong
[01:57:41] <LeelooMinai> It's the biggest I have anyways:)
[01:57:51] <XXCoder> yeah probably will work fine
[01:58:13] <XXCoder> will have washer to spread force correct?
[01:58:44] <LeelooMinai> I just tested it - it is perfect size - sits on the inner circle and sticks out a bit
[01:59:15] <LeelooMinai> Not sure though how I will cut that aluminum part though...
[01:59:34] <XXCoder> nice. you have jigsaw and belt sander roller?
[01:59:38] <LeelooMinai> That long cut is kind of outside of the range of my mitre saw
[01:59:51] <XXCoder> if so, print a design and cut em out, the finish using belt sander
[02:00:02] <XXCoder> (glue on alum sheet)
[02:00:35] <LeelooMinai> I have a jigsaw, but it's... a jigsaw - for delicate work. It would die on 1/4 aluminum
[02:01:08] <LeelooMinai> O have a band saw - not a big one, but I never can get straight cut with that one:/
[02:01:08] <XXCoder> no umm belt cutter? not too sure name
[02:01:21] <XXCoder> yeah thats why second step is belt sander
[02:01:32] <enleth> LeelooMinai: get a screw with a smooth section by the head for the hinge
[02:01:37] <XXCoder> since you have glued it on you leave mm or 2 all way around
[02:01:42] <XXCoder> then belt sand to line
[02:02:04] <enleth> LeelooMinai: thread used as hinge surface deforms pretty quickly and introduces slop
[02:02:05] <LeelooMinai> enleth: Right, that would be ideal, but would have to order it just for this.
[02:02:25] <enleth> LeelooMinai: so use what you have now and get a proper one later
[02:02:30] <LeelooMinai> Maybe will put those for a while and order when I will be prodering, right.
[02:03:36] <LeelooMinai> The guys on youtube always cut easily with band saws, but mine, I don't know - I edjusterd it and everything, but nothing. Maybe it's because they have much wider bands.
[02:04:02] <LeelooMinai> When I cut I end up with waves:)
[02:04:38] <XXCoder> odd
[02:04:51] <XXCoder> maybe google videos on how to tuneup band saw
[02:04:57] <LeelooMinai> Now, the mitre saw cuts well, because it has nice carbied blade for aluminum, but it can cut only max maybe 7 inches (it's not sliding)
[02:05:14] <LeelooMinai> E, 3-4 inches
[02:05:45] <LeelooMinai> I saw people using some metal saws, but I think they were for steel
[02:06:01] <LeelooMinai> Had toothless blades
[02:21:16] <XXCoder> its not toothless just more fine teeth
[02:21:45] <LeelooMinai> It looked like big cut-off wheel almost - I don't think it had teeth
[02:22:04] <XXCoder> hmm ok
[02:22:16] <enleth> LeelooMinai: did it give a lot of sparks, like an angle grinder?
[02:22:55] <LeelooMinai> I mean something like this: https://www.homedepot.ca/en/home/p.1000668808.html
[02:23:35] <LeelooMinai> So maybe it is a big cut-off wheel
[02:23:39] <enleth> there is this type of steel cutting device that basically turns a big abrasive wheel at angle grinder speeds, it's much cheaper than a proper toothed blade metal mitre saw
[02:24:22] <Deejay> moin
[02:24:58] <enleth> it's easier and cheaper to slap on a direct drive motor that turns the wheel at a high speed, than to gear it down or use a low speed high torque motor for a toothed blade
[02:26:58] <enleth> just like an angle grinder, it will make a very messy cut compared to a proper saw
[02:27:42] <LeelooMinai> I cut aluminum with normal wood mitre saw, but I guess I would not try this with steel
[02:28:44] <enleth> LeelooMinai: https://youtu.be/38yPR25VSw4?t=31s - this is the proper stuff for cutting steel, note how clean the cut is and how little sparks it makes
[02:30:03] <LeelooMinai> Right, I remember once I looked at one of those, but the price...
[02:30:21] <enleth> as I said, it's esier and cheaper to use an angle grinder style motor
[02:30:44] <enleth> that saw on the video is probably geared down
[02:30:59] <LeelooMinai> They say it's 1500 rpm
[02:32:15] <enleth> yep, geared down or a really nice beefy low speed motor
[02:32:26] <enleth> low speed compared to a 5kRPM angle grinder
[02:37:28] <LeelooMinai> I somehow managed to spill balls from a ball bearing in a CAD - fail
[02:37:43] <XXCoder> lol
[02:47:32] <CaptHindsight> hell, I would have cast that
[04:04:23] <enleth> pcw_home: should I expect any trouble if I connect 7i77's field outputs in parallel with relay outputs of another control, that switch the same 24V that power 7i77 field I/O onto the respective output?
[04:06:51] <pink_vampire> is there a quite material saw?
[04:07:02] <XXCoder> quiet?
[04:07:46] <pink_vampire> no noise
[04:08:16] <pink_vampire> the thing that you don't care about :-)
[04:08:28] <enleth> pcw_home: I assume the outputs shouldn't care about 24V being applied externally regardless of their own state
[04:09:55] <enleth> pcw_home: I guess the question could be rephrased as "are the outputs high-Z when low"
[04:12:18] <pink_vampire> i hate the band saw. a -lot of noise, the finish cut is vary poor, and it take forever
[04:13:16] <pink_vampire> XXCoder: what are you using for cutting stock material?
[04:13:23] <witnit> pink_vampire: maybe a good option for your shop would be like a http://vintagemachinery.org/photoindex/images/137-B.jpg
[04:13:44] <XXCoder> table saw heh (wood only, though can get metal saws)
[04:13:58] <enleth> pink_vampire: a reciprocating saw is quiet, but even slower
[04:14:18] <pink_vampire> witnit: i have a 2x3 aluminum bar that i'm slice each time
[04:14:23] <enleth> it sounds like someone going at it with a big hacksaw, plus some motor noise
[04:14:27] <witnit> ohhh
[04:14:30] <witnit> thats thick
[04:14:56] <witnit> maybe a properly mounted 6" slitting saw
[04:15:00] <witnit> and cold saw it
[04:15:10] <enleth> pink_vampire: you might also want a metal mitre saw like the one in the video I linked to earlier
[04:15:26] <enleth> pink_vampire: it's loud, but cuts *very* fast, so it's only loud for a moment
[04:15:45] <enleth> pink_vampire: https://youtu.be/38yPR25VSw4?t=31s
[04:15:49] <pink_vampire> cold cut saw is super noisy
[04:15:50] <XXCoder> or cancelling headphones
[04:15:57] <XXCoder> sound cancelling
[04:16:05] <pink_vampire> one sac
[04:16:07] <pink_vampire> brb
[04:19:18] <witnit> the only quiet way to cut them would be to turn them
[04:19:46] <witnit> but the corners would be hard to knock down without rigid machines
[04:20:36] <pink_vampire> i'm back
[04:20:37] <enleth> and parting off is still usually the loudest thing you can do on a lathe, unless you have some very high quality cutoff blades
[04:21:07] <pink_vampire> edm?
[04:23:41] <pink_vampire> enleth: the bar is about 6 feet
[04:24:55] <enleth> witnit: come to think of it, a shaper would do a better job with a rectangular bar if it needs to be quiet
[04:26:02] <pink_vampire> what is a "shaper"?
[04:26:18] <enleth> google "metal shaper"
[04:26:29] <enleth> but it's not a practical answer to your problem
[04:27:03] <enleth> quiet, fast, not-ridiculously-controved - pick two
[04:27:08] <enleth> *contrived
[04:27:27] <enleth> actually, pick one in most cases
[04:28:17] <archivist> to clean up the ends of a long bar on a shaper you need a hole in the floor
[04:28:42] <enleth> you could cut the side as well
[04:28:59] <enleth> or cut through the bar with a narrow tool
[04:29:16] <enleth> but it would still be extremely impractical
[04:30:07] <archivist> floor boards above pit removable http://www.collection.archivist.info/archive/DJCPD/PD/2001/2001_09_27_Claymills_Open_Day/P1010347.JPG
[05:12:29] <jthornton> morning
[05:18:24] <Deejay> hey
[05:59:02] <pink_vampire> hi Deejay
[06:21:20] <unfy> i sadly won't be awake much longer
[06:21:34] <unfy> but did encapsulation end up buying a machine finally ?
[06:22:02] <archivist> yes, then failed to put it together
[06:22:24] <archivist> so the saga still has no ending in site
[06:22:39] <unfy> failed to.... wha?
[06:22:41] <unfy> O_o
[06:23:43] <archivist> explanation of failure is...... interesting
[06:25:41] <unfy> i'll have to get more info later
[06:25:54] <unfy> for now, tnx archivist... glad to know he did finally buy something though :D
[06:25:59] * unfy go pass out
[06:38:46] <Magnifikus> so given i got servos with UVW and 3amp continues phase current (the original driver was sourced with 24V) with resolvers, any idea howto drive them? :)
[06:39:11] <Magnifikus> the integrated drivers are something 20 year old micros with not really working latencies
[06:56:27] <enleth> Magnifikus: so they're just 3-phase AC servos?
[06:58:33] <enleth> leadshine might have something suitable
[07:00:18] <enleth> Magnifikus: snap a few photos and email them with a description asking if any of their AC servo drives would fit
[07:45:21] <RedBull> I have a home built CNC plasma table. It uses stepper motors instead of servos. It's been working great months. I decided to buy a new plasma cutter. I hooked it up and as soon as the pilot arc came on, it smoked the control board.
[07:46:04] <RedBull> I'm baffled because the other plans cutters hf had no effect
[07:46:15] <RedBull> *plasma
[07:47:36] <archivist> bad grounding?
[07:50:27] <RedBull> Well the stepper controller and the plasma cutter share the same ground via the metal table.
[07:51:00] <archivist> check for a real connection
[07:51:05] <skunkworks> awesome
[07:51:07] <skunkworks> https://www.youtube.com/watch?v=ZUmiOHKrtPA
[07:52:16] <archivist> RedBull, a chinese cheapee or a better one
[07:55:44] <RedBull> There is a real connection. Well it's actually one I designed my self. I do a lot of Eda work
[07:59:17] <archivist> stepper cables all screened?
[07:59:37] <RedBull> I know that's gonna make it hard to diagnose. All the cables are sheilded.
[08:00:16] <RedBull> Proper use of ground planes and good techniques in PCB routing
[08:00:21] <archivist> but a broken shield
[08:02:05] <RedBull> The shielding ends at the connectors at the stepper motors, theres about 3 inches of unshielded non twisted wire.
[08:02:32] <archivist> we had all manner of flexible cable problems on one device I worked on in the 1980's taught me about bend radius's for flexible cables
[08:04:40] <archivist> and 3" is that enough if the plasma has a different frequency characteristic
[08:08:33] <RedBull> Idk. I mean I have big tvs diodes protecting the drivers
[08:08:53] <RedBull> I haven't pulled the board out yet to find out exactly what's bad
[08:10:06] <RedBull> How much energy can really be attenuated from 3" of wire that's at least 8" away from the cutting head
[08:10:24] <archivist> has it gone in on the mains input
[08:11:10] <archivist> you mean how much energy can be coupled
[08:17:29] <RedBull> Yea coupled. There are no inputs besides a touch screen. There's a shielded HDMI and usb cable that runs to it.
[08:18:00] <RedBull> That part of the system seems to working correctly
[08:20:18] <JT-Shop> crap usps labels are rotated today on the pdf
[08:20:32] <RedBull> The control is mounted in a nice Allen Bradly box. Good thick metal construction
[08:21:54] <archivist> yes but, if a panel edge has an effective slot it becoms an alforrd slot antenna which can couple energy into/out of a case
[08:22:24] <archivist> I would be checking filtering
[08:22:49] <archivist> and radiated energy with a spectrum analyser
[08:25:45] <RedBull> Yea I'll have to pick one of them up lol. I'm just baffled. The hf on this new cutter must be way higher frequency of something.
[08:25:51] <archivist> I bet it is an RF started arc Some cutters use a high voltage, high frequency circuit to start the arc. This method has a number of disadvantages, including risk of electrocution, difficulty of repair, spark gap maintenance, and the large amount of radio frequency emissions
[08:26:13] <archivist> that last part
[08:30:23] <TurBoss1> I need hep wih latch
[08:30:39] <RedBull> Yea it is hf start. But so was the old one
[08:30:52] <RedBull> Thanks your help!
[08:31:23] <archivist> RedBull, if a different frequency you now have a resonant cable/screen/whatever
[08:32:29] <TurBoss1> this is my hal file
[08:32:32] <TurBoss1> http://dpaste.com/0ZEPE7P
[08:36:38] <RedBull> archivist, I'm not following?
[08:39:08] <archivist> remember vibrating a ruler off the edge of a table, that is resonance, HF/RF excites/causes that in any metal item, cable, screens, table, needs to not affect anything
[08:39:25] <JT-Shop> TurBoss1: user interface, version, error?
[08:39:50] <TurBoss1> Axis Master , does nothing...
[08:40:02] <TurBoss1> hi
[08:40:22] <TurBoss1> iI cant enable the machin
[08:40:29] <TurBoss1> *machine
[08:41:36] <TurBoss1> I'm following this https://forum.linuxcnc.org/forum/47-hal-examples/25861-external-e-stop
[08:41:49] <JT-Shop> parallel port pin 1 can be a problem sometimes
[08:42:21] <JT-Shop> open a watch window and watch the state of remote-estop
[08:42:32] <JT-Shop> as you toggle the physical estop
[08:42:56] <archivist> I have had to add pullups to parallel port pins
[08:43:20] <TurBoss1> pullups are in place
[08:43:29] <TurBoss1> port.1.pin-10 works
[08:43:44] <JT-Shop> oh sorry I misread the line
[08:44:04] <JT-Shop> multi-tasking lol
[08:44:36] <TurBoss1> remote-estop signal works
[08:45:49] <TurBoss1> but the led attache to estop signal and the eable button in axis doesn't toggle
[08:45:57] <TurBoss1> attached*
[08:47:14] <JT-Shop> I don't have a computer handy with current master, can you try your config in 2.7?
[08:47:41] <TurBoss1> thi config hs use of joints
[08:47:52] <TurBoss1> but I can make a new one
[08:48:11] <TurBoss1> this little keybord is BS
[08:48:15] <TurBoss1> xD
[08:49:10] <TurBoss1> master is in run in place I can install linuxcnc 2.7 from the repos ?
[08:49:34] <JT-Shop> sure
[08:49:38] <TurBoss1> ok
[08:56:21] <TurBoss1> JT-Shop: I get the same behaviour
[08:56:54] <TurBoss1> the same effect nothing happendsñ
[08:58:58] <TurBoss1> hmmmmm
[09:01:44] <TurBoss1> ok I noticed th if i release the estopin axis with the mouse i can activate emergency by the external
[09:02:08] <TurBoss1> but can release it again
[09:02:32] <TurBoss1> i didn't notice this because i was commenting the original lines tht handles axis estop
[09:02:45] <TurBoss1> this happends in master and 2.7.6
[09:02:51] <TurBoss1> same effect
[09:04:37] <JT-Shop> that may be by design, you can only release the estop from axis if the external is not active
[09:05:11] <TurBoss1> yep it's ok but i can't release it by external
[09:06:11] <TurBoss1> so external activates emergency but can't deactivate it
[09:07:45] <JT-Shop> looks that way
[09:07:52] <JT-Shop> I can't test now

[10:06:16] <gregcnc> strange, shipped fri, scheduled delivery tue.
[10:06:31] <ctjctj> Hello. I need verification on a method I'm attempting for manual tool changes. Step 1) Tool 1 is selected with T1. 2) Turn off tool offsets and do a touch off to set a Z zero. 3) touch of on tool length touch plate and record in #4999. 4) On next tool change I turn tool offset off, probe the tool length touch plate. I then set the tool length offset to probe height delta #4999. I then turn tool offsets on again. At this
[10:06:31] <ctjctj> point the commanding a Z0 should move the tool tip of T2 to the same hight as T1 was at?
[10:06:47] <CaptHindsight> gregcnc: maybe they changed now that it's MSC
[10:08:09] <gregcnc> could be capt
[10:10:58] <cradek> ctjctj: here's my m6 remap code that does probing and writes the length to the tool table: http://timeguy.com/cradek-files/emc/manual_change.ngc
[10:11:01] <CaptHindsight> gregcnc: was 1 day from IN, but 3 days from PA
[10:11:55] <cradek> I don't understand what you're doing with #4999
[10:12:03] <cradek> #5063 is the probe result
[10:12:23] <MacGalempsy> good morning
[10:14:56] <ctjctj> cradek How is that installed?
[10:16:12] <cradek> REMAP=M6 modalgroup=6 ngc=manual_change
[10:17:02] <cradek> http://www.linuxcnc.org/docs/html/remap/remap.html#_making_minimal_changes_to_the_built_in_codes_including_tt_m6_tt
[10:21:47] <cradek> here were my goals: don't invent a new kind of offset. for tool lengths use the tool table. with this remap I can load any tool and then touch off any work coordinate system (g5x) in the normal way using it.
[10:22:07] <cradek> (g30 is set to be above the tool length sensing switch)
[10:22:48] <cradek> also this is tolerant of part programs in different g20/g21 units. be aware that it's easy to screw that up if you invent new kinds of offsets yourself...
[10:25:11] <ctjctj> cradek, thanks. I'm looking through this and I do understand lots of it. Here is what I was thinking. If I'm setting zero off the top of the stock I might no longer have that zero when I do the next tool change. I want to be able to return to that same zero point at any time, regardless of the tool I have loaded.
[10:26:02] <ctjctj> So I touch off and now have a Tool with zero offset who's tip is at the zero location.
[10:26:59] <ctjctj> When I change the tool I have a random offset. I need to figure out how long that tool is relative to the original tool. I can measure that by first measuring the original tool and recording its "length" in #4999.
[10:27:35] <MacGalempsy> ctjctj: are you working with repeatable tooling?
[10:27:44] <ctjctj> Now when I touch the tool length probe with the new tool. The difference between #4999 (original tool length) and #5063 is the difference in length of the tools.
[10:27:46] <MacGalempsy> manual or automatic tool change?
[10:27:59] <ctjctj> MacGalempsy, nope. Manual tool change with cheap spindle and simple collets.
[10:28:17] <ctjctj> MacGalempsy, think ER20
[10:31:55] <MacGalempsy> I use those er20 too
[10:32:01] <MacGalempsy> max 1/2"
[10:32:16] <ctjctj> MacGalempsy, yep.
[10:32:25] <MacGalempsy> so far I have only used single operations, so I use T1
[10:33:19] <MacGalempsy> and move the spindle down by .001 until it touches the work piece, then hit touchoff then tool touchoff at the same place
[10:36:27] <ctjctj> MacGalempsy, that's the way everybody starts. I suggest a piece of paper (measure it) between the tool and work piece. It is easier to "feel" when it touches off.
[10:39:05] <cradek> ctjctj: don't use the tool length probe to find the difference between two tools - use it to find the length of the tool directly according to the fixed location of the switch on the machine. see docs for G10 L11: http://www.linuxcnc.org/docs/html/gcode/g-code.html#gcode:g10-l11
[10:40:10] <ctjctj> credek, Thank you for the reference. I'm still trying to wrap my head around this. I don't have good "home" locations so I wasn't using absolute values.
[10:40:40] <cradek> oh you don't have home switches? you should still find a way to home in the same location every time you start up
[10:40:49] <cradek> mark the spot with a sharpie if you need to
[10:41:04] <ctjctj> cradek, absolutely. But that's only good for a few thousands.
[10:41:46] <cradek> yes you'll probably have to reload your tool after restarting (causing it to re-probe)
[10:43:18] <Simonious> so it was recently suggested to me that I use ONE input pin for HOME, and just touch off of each switch and this seems okay, but I suspect it'll introduce error when I do a tool switch if I rehome and the act of manually switching tools can introduce error, so I'm certainly interested in rehoming..
[10:43:20] <ctjctj> Let me trying to say this differently: I know that the probe is at X,Y,Z in G53 absolute. But that "wonders" a bit because of homing issues.
[10:44:12] <ctjctj> So I load T1. Now T1 is going into an ER20 collet so even if I had the "right" tool offset it would not be valid anymore. So I probe and I know know a G53 Z for that tool.
[10:44:43] <ctjctj> But what does that mean? I think that's my problem.
[10:45:07] <cradek> well in that case, your workpiece moves too
[10:45:17] <ctjctj> Cradek yes. It does.
[10:45:25] <cradek> so you'll have to use your newly-probed tool with today's correct tool length offset to touch off the workpiece again
[10:45:49] <cradek> you have one offset for the workpiece, one for the tool
[10:46:04] <cradek> they both get screwed up when you rehome
[10:46:22] <cradek> you establish tool offset using the switch; you establish workpiece offset using the correctly-measured tool
[10:46:33] <cradek> don't make up a third offset
[10:50:33] <ctjctj> cradek, thank you. I'm slowly wrapping my head around it.
[10:50:43] <cradek> welcome! it's tricky :-/
[10:51:57] <ctjctj> So I'm going to throw some numbers up here to help me. As I do it now: Load tool. Tool offsets are disabled. I move to the work piece and touch off. I now have a -3.5 in the G54 Z offset.
[10:52:12] <ctjctj> Thus when I move to G54 g0z0 I will be at that zero.
[10:52:22] <cradek> you shouldn't touch off a workpiece with an unmeasured tool
[10:52:38] <ctjctj> Cradek that's how I currently doing it.
[10:52:56] <ctjctj> New method: I load tool. I measure it with the tool probe.
[10:53:11] <ctjctj> Now I have a tool offset. Call it -2.25
[10:53:25] <ctjctj> I turn on tool offsets and now do the touch off.
[10:53:50] <ctjctj> When I do this the G54 Z offset will be different by 2.25 because I've "measured the tool".
[10:53:54] <ctjctj> Do I have that much right?
[10:55:51] <ctjctj> So now I do a tool change. I measure the new tool and instead of -2.25 I get -2.125. G54 Z does not change but the 2.25 difference is going to be 2.125 which will take me to the same zero in G54...
[10:56:08] <ctjctj> If I got that right your/linuxcnc method is much simpler than what I was thinking.
[10:57:10] <ctjctj> *chuckles* I was thinking of "measuring" the tool. I don't care what the actual measurement is. I just care where the tip of the tool is relative to something machine Z.
[10:59:11] <cradek> yes when you load another tool it'll get a different offset
[11:00:26] <cradek> g54 doesn't change, but after g43 your new tool will line up with it
[11:00:58] <ctjctj> cradek. Thank you. The clue by four landed and I think I get it now.
[11:01:09] <cradek> yay!
[11:02:44] <ctjctj> The key is that I'm not measuring the length of the tool but a relative distance. That makes much more sense.
[11:13:15] <roycroft> grr
[11:13:26] <roycroft> why was i not aware of these things until just now?
[11:13:31] <roycroft> http://www.mcmaster.com/#90291a619/=13xqpua
[11:13:50] <roycroft> for years/decades i've been doing elaborate things to prevent set screws from making pock marks in soft materials
[11:14:32] <ctjctj> cradek, don't you need to do the "G91 G0 Z0.1 (At 10IPM move up 0.1 inches)" with a G38 type retract?
[11:18:16] <nubcake> RedBull, i was trying to figure if- and where-to add the limit switches on this or any of the other boards that are inside of my chinese-cnc controller box. (regarding this link: http://goo.gl/8YQDiW )
[11:23:52] <ctjctj> cradek, my probe code looks like "G38.2 Z-3 F12 (fast down)" "G38.5 Z[#5063_0.25] (Fast up)" "G38.2 Z-3F1 (slow down)" This is the value used. Then finally "G38.5 Z[#5063+0.5] F100 (fast retract to disengage)". I think I did this because the momentum would get a little push on the probe plate (spring loaded, not an issue). So it would trigger as a probe fire while moving without G38 probe.
[11:27:04] <ctjctj> cradek, In your manual_change you have a "G0 G90 G53 X3.7440" but then you do a G30 to go to the probe position. Why is there a movement in X before you move to the probe position?
[11:27:52] <cradek> the tool can be hard to get out if there's workpiece under it
[11:28:27] <cradek> I don't mount stuff over on the right end of the table (where the tool length switch is)
[11:29:40] <ctjctj> cradek, thanks, that makes perfect sense.
[11:30:02] <archivist> looks dangerous "G38.2 Z-3 F12 (fast down)"
[11:30:30] <ctjctj> cradek, so you retract, move a little bit, do the tool change, then the rest of the probing takes place.
[11:30:39] <cradek> yep
[11:30:48] <cradek> archivist: the switch has plenty of overtravel
[11:31:19] <archivist> and shit never happens :)
[11:31:27] <ctjctj> archivist, that is in machine coordinates so it is fairly safe and for most reasonable tools it won't even reach table height. The probe switch has 0.5 inches of travel.
[11:33:05] <ctjctj> archivist, this is what my probe touch plate looks like. Except the disk is aluminum instead of brass. Self made touch plate. http://www.cncrouterparts.com/auto-z-touch-plate-p-288.html
[11:57:12] <pink_vampire> ctjctj: WOW 90% for that??
[11:58:09] <pink_vampire> 90$ *
[11:58:44] <Simonious> pink_vampire: I may pick one of those up at some point, will you make one for me for less $?
[11:59:34] <pink_vampire> you can make one for yourself with your cnc machine.
[11:59:52] <Simonious> true, but if I bill my time I'll probably come out cheaper ordering one.
[12:00:05] <Simonious> (not probably, most certainly)
[12:00:17] <pink_vampire> it's 3 parts..
[12:00:30] <Simonious> pink_vampire: so you'll do it then?
[12:00:54] <pink_vampire> no
[12:00:58] * Simonious chuckles
[12:01:27] <pink_vampire> i want to make something kinematic and none metallic

[12:59:22] <archivist> he never stops long, that may be a record
[13:22:28] <ctjctj> cradek, I am now debugging my version of it. But it is doing something. When should it execute the change_tool sub? When it sees a T# or when it sees M6?

[13:33:29] <ctjctj> JT-Shop, thank you.
[13:49:43] <Simonious> so does BOB need that USB port connected? http://www.collection.archivist.info/archive/mirror/cnc/bob/$_58.JPG
[13:53:02] <archivist> not if you get 5v to the other 5v screw connector, it is a choice
[13:54:47] <Simonious> ahh, okay, great
[13:55:05] <Simonious> I know it's a simple board, but is there some documentation on this board?
[13:56:16] <archivist> not a lot, I collected those three docs in that subdirectory
[13:57:27] <ctjctj> Is there a page that talks about pendents and makes any recommendations? I'm hoping for something USB based.
[13:57:46] <Simonious> ctjctj: ahh, I might have something for you
[13:59:05] <gregcnc> is this still popular? http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Using_A_XHC-HB04_Wireless_MPG_Pendant
[13:59:13] <Simonious> that's what I'm using
[13:59:29] <Simonious> ctjctj: so.. that's more or less what I was going to find for you :)
[14:00:29] <ctjctj> thank you both.
[14:05:18] <Contract_Pilot> Ahhh coffee
[14:06:00] <gregcnc> I don't have a caffeine problem, I have a lack of caffeine problem
[14:14:09] <ctjctj> gregcnc, to much blood in the caffeine stream?
[14:14:27] <gregcnc> not any more
[14:40:05] <enleth> gregcnc: try Club Mate or something similar
[14:41:05] <enleth> if my experience is any indication, it can work much better than coffee when you get into the flow and work for 20-something hours straight
[14:42:36] <enleth> doesn't cause heartburn, for one, if you happen to suffer from that after too much coffee
[14:43:14] <gregcnc> hah, a dunkin donuts 12oz coffee is too much for me. I make two cups a day. 1 in am and 1 after lunch
[14:45:39] <gregcnc> https://youtu.be/KXRmdDAWHMg?t=4m36s is this a typical fusebox in germany/europe?
[14:46:10] <kengu> gregcnc: yes
[14:48:09] <enleth> gregcnc: a residential one, yes
[14:51:47] <ctjctj> Simonious, does the wired version work also? https://www.amazon.com/XHC-HandWheel-Optical-Generator-Controller/dp/B0154JK0OC
[14:52:08] <Simonious> ctjctj: I suppose, but why go wired?
[14:52:18] <enleth> gregcnc: usually they're a bit more messy, though
[14:52:31] <Simonious> the wireless one has been working pretty well for us
[14:52:45] <enleth> and the neutral and earth buses are just brass blocks with screw-clamped holes
[14:52:52] <ctjctj> I didn't find it in my searches and then there it is on the bottom of that page. Thank you.
[14:53:07] <Simonious> ctjctj: be aware it doesn't have an auto-off timeout feature as far as I can tell
[14:53:17] <Simonious> ctjctj: not that I've studied it..
[14:53:55] <gregcnc> it looked pretty clean, I guess when you have only a few breakers it doesn't take much
[14:55:08] <enleth> gregcnc: that actually looks like a main panel for a small two-story house
[14:55:35] <ctjctj> I'm having too much fun with pyvcp right now. Learning how to make subroutine calls in ngc made life better for me. And cradek giving me some sample code helped even more. I was doing lots of things in machine coordinate space and absolute because I didn't understand how to use G90/G91 codes. Or the fact that you can use them for just one line.
[14:55:41] <kengu> enleth: or a flat, or what ever.
[14:56:07] <enleth> kengu: that would be a rather huge flat, or a rather overengineered one
[14:57:53] <enleth> overengineered quantity-wise, that is
[14:59:30] <enleth> quality-wise it would be wired with stranded instead of solid wire, with terminal blocks separating the internal wiring from the solid copper wall wiring
[15:26:17] <kengu> enleth: 27m^2 flat in Finland, I used to live in one, https://scontent.xx.fbcdn.net/v/t34.0-12/14182138_1767374450172585_1333004564_n.jpg?oh=a1d743b85a38f4535d2bcdb8342fcddb&oe=57C73F48
[15:42:17] <MacGalempsy> everyone having fun today?
[15:42:24] <Tom_itx> NO!

[15:44:36] <Polymorphism> hurrah!
[15:44:38] <Polymorphism> the cnc will be built
[15:44:42] <Polymorphism> updates soon
[15:45:13] <Polymorphism> I'm taking it to the machine shop at my school and the prof can't wait to show a real world problem to students and help me assemble and square it up
[15:45:23] <Polymorphism> plus I might even get extra credit. Win-win
[15:45:28] <Polymorphism> afk a while, bbl
[15:45:32] <MacGalempsy> Tom_itx: check out what I'm going to look at tomorrow. http://fortsmith.craigslist.org/tls/5746704034.html
[15:47:55] <_methods> ah nice drill press
[15:48:04] <_methods> that's a score at $250
[15:48:16] <MacGalempsy> yeah, untested, but still worth it
[15:48:58] <MacGalempsy> pickup a cheap VFD and hopefully the motor is good
[15:49:32] <Tom_itx> nice
[15:49:55] <enleth> kengu: three separate RCDs? someone didn't like half-measures
[15:50:49] <kengu> three phase, three rcd?
[15:51:54] <enleth> but no single high current three-phase RCD
[15:52:30] <enleth> was there actually any three-phase appliance in there?
[15:52:39] <kengu> on second look. they are for different outlets.
[15:52:49] <enleth> yeah, that makes more sense
[15:53:28] <MacGalempsy> I wish I had a place to test the 3 phase motor before buying a vdf
[15:53:30] <MacGalempsy> vfd
[15:53:31] <enleth> honestly, I'd appreciate something like that being standard in central Europe, but it isn't, because you can do it way cheaper and most of the time whoever pays for it won't be any wiser
[15:53:59] <enleth> which is why I'm not touching residential wiring with a ten foot pole
[15:57:22] <kengu> enleth: http://offshore.vaasa.hacklab.fi:9090/file_188.jpg 60m^2 of hacklab electricity
[15:58:56] <enleth> kengu: I guess you could say that those panels look alike in most of the Europe in the sense that an electrician from almost any country here won't be surprised when attempting to work on a panel in a different country - same enclosure styles, protective devices and terminals made by the same suppliers, similar electrical code and so on - but there is a huge variation in average quality and attention to
[15:59:02] <enleth> detail
[15:59:28] <kengu> yes.
[16:01:41] <kengu> what is a reasonable 2A stepper driver? a bit up from A4988
[16:01:45] <enleth> kengu: I've done something similar for the local hackerspace, we had a 90kW uplink at the previous place
[16:04:50] <enleth> kengu: ST powerSTEP might be what you're looking for
[16:05:37] <enleth> I haven't had a chance to use them but that's what I'd try if I needed a stepper driver in this current range
[16:07:43] <kengu> hmm.. interesting
[16:08:17] <enleth> it's a bit pricy but not prohibitively so and will push 10A
[16:09:03] <enleth> and there isn't really much in between that and Allegro chips
[16:15:13] <andypugh> Due to be trying to do my job in Turkey for the next 2 weeks.
[16:15:37] <andypugh> On a facility I have never used, where I don’t know anybody, and I don’t speak the language
[16:15:45] <andypugh> Can’t say I am looking forward to it.
[16:16:21] <Deejay> hmm, say you are ill and cannot go ;)
[16:16:40] <enleth> try not to look like an anti-presidental revolutionary I guess
[16:17:02] <andypugh> Oh, and it’s a job I haven’t done before, I was meant to be learning on the job since February, but lack of facility means I now have 4 weeks total to do everything from scratch, in a foreign country.
[16:18:03] <andypugh> I guess it could be worse. But not in all that many ways :-)
[16:22:44] <enleth> andypugh: a friend worked for a telecom equipment supplier who, due to acquisitions, happened to have support contracts with government and military customers in both Israel and Syria. And he had to make on-site visits for both. He requested for a second passport - and actually got it - so that his travel history looked "clean" to either country's border guards, and he had to remember to take the correct
[16:22:50] <enleth> passport with him each time to be safe.
[16:24:32] <andypugh> enleth: yes, my dad had the same setup. He worked in Isreal and Egypt. I am not altogether sure he didn’t end up with 3 passports by the end. He went to all sorts of odd places, even countries that were technically closed, like Burma.
[16:24:34] <enleth> They'd probably just throw him out of Israel immediately if they saw Syrian border stamps for business visits, but Israeli stamps in Syria could mean being detained and who knows what else.
[16:27:17] <Deejay> gn8
[16:27:19] <MacGalempsy> http://fortsmith.craigslist.org/tls/5720829694.html this looks cool
[16:27:22] <enleth> During one visit, he was servicing some stuff in a syrian military compound and the armed guards who accompanied him all the time casually told him that they had just caught an Israeli spy a few days prior, trying to bug the equipment.
[16:27:47] <enleth> He was fresh out of Israel at the time, just stopping somewhere safe to swap passports.
[16:28:29] <andypugh> MacGalempsy: Is that a reel-to-reel tape deck? Or something to do with re-spooling wire?
[16:28:47] <MacGalempsy> lol. thats exactly what I was wondering
[16:28:47] <enleth> Quit that job for the fear that he'd make a mistake someday and get caught with the wrong papers in a wrong place.
[16:29:43] <MacGalempsy> maybe that is where the dj tweeks the feed rates simoultaneously
[16:30:09] <andypugh> I won’t pretend that I am not a little leery of the current situation in Turkey. Especially as I have a suitcase full of glow-plugs, control modules and wiring loom.
[16:30:38] <andypugh> The glow plugs look a lot like detonators, just to make it more interesting.
[16:30:43] <MacGalempsy> shit, sounds like they would try to recruit you for their movement
[16:31:05] <andypugh> I am half expecting not to get my luggage, and to be unable to do anything.
[16:32:13] <enleth> MacGalempsy: I have a lathe with a factory fitted cassette deck and stereo speakers, beat that
[16:32:25] <MacGalempsy> can you fedex the stuff to the job site?
[16:32:40] <MacGalempsy> and just wear your mechanics uniform
[16:33:02] <andypugh> MacGalempsy: Too late. And too slow. Part of the reason that things are so tight is that a bunch of important parts spent a month clearing customs.
[16:33:26] <kengu> enleth: multiple passports is standard issue on those situations
[16:33:46] <MacGalempsy> best of luck on that trip!
[16:35:19] <MacGalempsy> andypugh: so what do you think about this. on this vfd for my mill set the P=1 I&D=0, then try tuning the PID through Linuxcnc?
[16:36:01] <andypugh> Any reason to think that a P of one is correct?
[16:36:20] <andypugh> Sounds high.
[16:36:39] <andypugh> (error of 1 rpm = 1 volt of VFD command)
[16:36:41] <MacGalempsy> well, I am trying to bypass the internal PID controller
[16:37:19] <MacGalempsy> with set values, so LCNC can control the spindle orientations with its PID
[16:40:07] <MacGalempsy> any thoughts on if this is a good idea, or should I just go with thread milling
[16:40:24] <andypugh> Try it. P=1 might be high, but a runaway spindle is fairly benign.
[16:41:26] <andypugh> MacGalempsy: I am not seeing how PID spindle orientation and thread-milling fit together?
[16:42:36] <andypugh> Are you trying to single-point thread with a milling machine?
[16:42:41] <andypugh> Like this: https://youtu.be/i4fTythQj5s?t=59s
[16:42:44] <MacGalempsy> I guess spindle orientation is a benifit, but I was hoping that I could rigid tap with a controlled spindle
[16:43:38] <andypugh> You can rigid-tap with an uncontrolled spindle :-)
[16:43:50] <andypugh> You slave the Z feed to the spindle encoder.
[16:44:52] <MacGalempsy> if I pickup that drillpress tomorrow, it will need a vfd, maybe i could just do tapping on that
[16:58:55] <andypugh> If you get a tapping head, maybe.
[16:59:14] <andypugh> But to rigid-tap with LinuxCNC all you need is a spindle encoder.
[17:03:49] <LeelooMinai> Is that all? How about normal spindle not having enough torque at low speed?
[17:04:20] <gregcnc> a normal spindle would have the torque, the high speed spindles don't
[17:04:22] <LeelooMinai> Or is that not a problem?
[17:05:23] <SpeedEvil> yes, it's a problem
[17:09:11] <LeelooMinai> Hmm, those tapping heads are expensive
[17:57:10] <TurBoss1> JT-Shop you up?
[17:57:39] <TurBoss1> can you tell me what i need to get the estop disabled when i release the emergency??
[17:57:41] <TurBoss1> thx
[17:58:04] <TurBoss1> actully on Master with Axis
[17:58:35] <TurBoss1> if i push the emergency button it holds the ignl but when i release it nothing happends
[17:58:44] <TurBoss1> signal*
[17:59:49] <MacGalempsy> sounds like you need to drive the signal the opposite way
[18:01:30] <TurBoss1> hi MacGalempsy
[18:12:18] <andypugh> TurBoss: Does LinuxCNC “See” the e-stop?
[18:13:24] <TurBoss> sry how i can check that?
[18:13:44] <TurBoss> parport.1.pin10-in is working
[18:13:52] <andypugh> I was assuming you would know
[18:14:06] <andypugh> It was a question about how you have configured it.
[18:14:25] <TurBoss> with a latch
[18:14:25] <MacGalempsy> andypugh: last night when I was chatting with him, he was able to see the estop pin go true
[18:14:41] <MacGalempsy> TurBoss: can you post your file again?
[18:14:55] <TurBoss1> sure
[18:14:57] <andypugh> So, you probably need to relase the physical button, then take LinuxCNC out of e-stop
[18:15:41] <TurBoss1> http://dpaste.com/1NS82VG
[18:15:54] <TurBoss1> i release the keep button but it does nothing
[18:16:50] <MacGalempsy> are all the conditions met?
[18:16:50] <TurBoss1> well halmeter show pin 10 in toggle
[18:16:59] <MacGalempsy> The state changes from "Faulted" to "OK" when all these conditions are true:
[18:16:59] <MacGalempsy> •fault-in is false
[18:16:59] <MacGalempsy> •ok-in is true
[18:16:59] <MacGalempsy> •reset changes from false to true
[18:17:25] <TurBoss1> sry mouse died give me a sek
[18:18:20] <TurBoss1> I don't need a mouse ! xD
[18:19:28] <TurBoss1> yes i need amouse...
[18:22:22] <TurBoss1> ok:in is not toggle, I need to wire it?
[18:22:49] <TurBoss1> *ok-in
[18:25:02] <MacGalempsy> what about fault-in?:
[18:25:13] <TurBoss1> yes that works
[18:25:22] <MacGalempsy> how about ok-in?
[18:25:34] <TurBoss1> nothin is coneccted to it
[18:26:13] <TurBoss1> i need to wire to the parport pin 10 again but in the oposite level?
[18:26:16] <MacGalempsy> http://linuxcnc.org/docs/html/man/man9/estop_latch.9.html
[18:26:39] <MacGalempsy> those are the instructions for that component, you need to meet the conditions from "Faulted" to OK
[18:27:33] <TurBoss1> ok I'm missing the ok-in
[18:35:03] <TurBoss1> MacGalempsy: what pi i should connect to the ok-in?
[18:35:07] <TurBoss1> *pin
[18:36:08] <MacGalempsy> how about reset?
[18:36:43] <TurBoss1> so reset => ok-in?
[18:37:35] <MacGalempsy> not sure
[18:38:36] <MacGalempsy> i think it will work
[18:39:05] <MacGalempsy> because when you reset the pin it will go to true and you want ok-in to be true
[18:39:18] <TurBoss1> checking now
[18:43:05] <TurBoss1> doesn't work
[18:43:19] <TurBoss1> sorry I have to leave
[18:43:26] <TurBoss1> thank you all
[19:01:30] <ctjctj> cradek, Thank you. With a little bit of work I was able to take your tool change sub routine and make it work for my setup. Little things like adding an M1 to allow me to disconnect the probe and turn on the router at the end of the move.
[19:02:05] <cradek> awesome!
[19:02:15] <pfred1> cradek hey where have you been?
[19:02:15] <ctjctj> Is there any register that holds the machine location? I want to save the G53 X, Y position before I start moving the spindle around to be able to return to the starting location after the tool change is done.
[19:02:27] <ctjctj> cradek, he was teaching tool offsets earlier today.
[19:02:46] <cradek> ctjctj: in general that's not safe, since you could have a longer tool than before
[19:03:02] <cradek> best to go up all the way and then go to your workpiece origin
[19:03:46] <cradek> maybe like g0 g53 z0 (up); g0 x0 y0 (to workpiece); g0 z1 (go down to above the workpiece)
[19:03:55] <ctjctj> cradek, my tool probe ends with a retract to max Z (highest point possible). Then it will travel to G53 original
[19:04:17] <cradek> oh hmm, for XY original
[19:04:34] <cradek> not sure
[19:04:53] <cradek> you could use g28.1/g28 but it's a shame to waste those saved positions
[19:05:01] <ctjctj> So my CAM software does a retract to a "safe" location for a tool change. G53 G0Z0. Then it does the T# M6 which then executes my routine.
[19:05:21] <cradek> usually after a tool change CAMs and programmers just consider the location as unknown, and make no assumptions, and do a fully controlled entry into the part
[19:05:52] <cradek> no machines I've ever seen automatically attempt to go back to the old location after a tool change
[19:05:54] <ctjctj> My routine then moves to a "tool change position" and does the actual M6. I press the continue and your probe software does the rest.
[19:06:02] <ctjctj> cradek, then I will stop doing it.
[19:08:36] <zeeshan> anyone else been playing around with linuxcnc-features?
[19:08:49] <MacGalempsy> kind of
[19:09:12] <MacGalempsy> getting ready to play around with the Run command
[19:09:30] <pfred1> I've been getting a lot of real time delays I need to do the isocpu thing I think?
[19:10:17] <pfred1> well, not a lot but intermittant every now and again one will pop up
[19:10:30] <zeeshan> run command? :D
[19:10:38] <cradek> usually that's a bios setting or a video card problem
[19:10:56] <pfred1> I use on board intel video
[19:11:01] <cradek> isolcpus probably won't help unless the overrun is minor
[19:11:14] <cradek> check bios settings like powersave, clock speed scaling, etc, first
[19:11:20] <pfred1> k
[19:11:34] <pfred1> I think ti is the same PC as this one is
[19:11:57] <pfred1> cept this one does have a video adapter card in it that one doesn't
[19:12:38] <MacGalempsy> zeeshan: yeah, it is the one that makes it all start spinning and moving around and stuff
[19:12:47] <zeeshan> o
[19:12:57] <pfred1> I bought a few PCs from a senior center
[19:13:00] <MacGalempsy> but first I will play around with the estop while the a axis is removed
[19:13:14] <pfred1> old folks don't know what they're doing with PCs it seems
[19:13:22] <zeeshan> MacGalempsy: http://imgur.com/a/bn03Z
[19:13:32] <zeeshan> thats how i machined the copper gasket
[19:13:44] <MacGalempsy> like a pimp
[19:41:02] <pfred1> the right PSU for a CNC machine is always an issue
[19:41:33] <pfred1> I made a good one for the drives I have now but I am upgrading them, and i need higher voltage to run them at peak
[19:41:54] <malcom2073> I'm a big fan of Antek power supplies
[19:41:58] <pfred1> but of course it is some stupid non common voltage
[19:42:36] <pfred1> malcom2073 i am a big fan of simple linear supplies myself just a step down xformer with a bridge and some filter caps
[19:42:46] <malcom2073> pfred1: That's what Antek's are
[19:43:08] <pfred1> oh yeah?
[19:43:13] <malcom2073> http://www.antekinc.com/power-supplies/
[19:43:18] <malcom2073> I have like, 5 of them
[19:43:46] <pfred1> hmmm I think $162 is more than i spent on my whole machine
[19:44:11] <malcom2073> Well, if you're going for a dirt cheap machine, scavange something from an old PC :)
[19:44:14] <pfred1> it looks like it would do the trick though
[19:44:31] <pfred1> nothing in an old PC has the voltage i need
[19:44:48] <pfred1> they only go up to 12V
[19:44:58] <pfred1> I need 40VDC
[19:45:00] <malcom2073> True, but on a cheap machine you can often get by on low voltages
[19:45:14] <pfred1> nah I run 28VDC now
[19:45:41] <pfred1> I have a xformer out of an old minicomputer and i put 2 13.5 windings together on it
[19:46:18] <pfred1> thing is big enough to anchor a small boat
[19:46:41] <pfred1> it ran a computer about 8 feet tall
[19:46:59] <gennro> thats pretty small minicomputer
[19:47:11] <pfred1> yeah it was a PDP 11/34
[19:47:42] <gennro> i was mostly being sarcastic in that statement
[19:47:49] <pfred1> 25 grand in 1970s money
[19:48:26] <pfred1> it used to do the booking for Newark International airport
[19:48:46] <pfred1> had about as much horsepower as a smartwatch I'd say
[19:48:53] <gennro> lol
[19:49:12] <pfred1> you should see the HDDs it had in it
[19:49:23] <pfred1> I made them into tool drawers
[19:49:31] <pfred1> deep long tool drawers
[19:49:39] <gennro> I bet
[19:49:55] <pfred1> really nice accuride drawer guides though
[19:50:17] <pfred1> someplace i have a picture of them
[19:50:54] <pfred1> http://i.imgur.com/LiW07qB.jpg
[19:51:06] <pfred1> I hacked the whole cabinet in half
[19:51:24] <gennro> nice
[19:51:36] <pfred1> but those were the HDDs
[19:52:30] <jdh> I have two pdp11/73's running
[19:52:46] <pfred1> jdh good heat
[19:52:52] <jdh> not really
[19:53:22] <pfred1> this computer had 2 8" fans in the top of it
[19:53:50] <pfred1> I swear you could feel the breeze off one of them from a good 20 feet away
[19:54:43] <jdh> mine are in plain old ba23 cases, 4U maybe
[19:55:13] <pfred1> the 11/34 looked like a closet on wheels
[19:55:38] <pfred1> I still have the side panels kicking around I use them as portable work tables
[19:57:19] <pfred1> it was a great salvage
[20:07:58] <Lowridah> they have a lot of pdps running at the living computer museum in seattle
[20:08:18] <Lowridah> they basically suck up electricity and look spinny and blinky
[20:11:39] <pfred1> someplace i still have the front panel
[20:42:44] <jdh> mine are in production 24/7
[20:51:59] <Cromaglious_> smoke 2 test
[20:57:20] <Cromaglious_> nothing smoked YEA!!!
[21:01:57] <pfred1> yea!
[21:12:46] <Cromaglious_> nothing moved either...
[21:13:49] <Cromaglious_> 27VDC on the drivers
[21:14:13] <Cromaglious_> +5 -clk -cw -en all wired right
[21:31:34] <pfred1> sometimes i have that problem
[21:31:53] <pfred1> sometimes the linuxcnc driver just doesn't seem to send any output
[21:32:09] <pfred1> rebooting usually fixes it well rebooting has always fixed it so far
[21:46:44] <MacGalempsy> finally got that vise square within 0.0001
[21:47:12] <MacGalempsy> malcom2073: whats going on?
[21:49:46] <pfred1> MacGalempsy what are you grinding?
[21:50:33] <MacGalempsy> nothing, I am preparing to run the CNC in the morning after the wife goes to school
[21:51:03] <MacGalempsy> but had pulled out the vise to mess with the 4th axis
[21:52:19] <pfred1> when I worked in a tool and die shop we didn't expect more than a couple thousandths accuracy out of any of our cutting machines if we wanted something to the ten thousandth we ground it after we hardened it, of course
[21:52:49] <MacGalempsy> just setting up to the best I can
[21:53:07] <pfred1> yeah standard practice is the best that you need to
[21:53:41] <MacGalempsy> well, I am shooting for um accuracy on the machine I am building
[21:53:53] <pfred1> a ten thousandth is like 3 swipes on 600 grit wet or dry paper
[21:55:03] <Cromaglious_> I compiled ParallelPortTest and it's working from that. It's just setting up linuxcnc to see it again... 0x378 didn't work
[21:55:21] <pfred1> Cromaglious_ yeah no signal
[21:55:40] <dioz> anyone a professional irc'r?
[21:55:40] <pfred1> when i built my drives i used a simple timer circuit to do the testing
[21:56:02] <pfred1> computer just adds another layer of complexity to it all
[21:56:31] <Cromaglious_> using ptest I was getting it to step. so the BOB is seeing the parallel port and it's working...
[21:56:42] <pfred1> that's a plus
[21:56:43] <Cromaglious_> stepconf isn't seeing it
[21:58:08] <pfred1> hrm you have a separate parallel port card?
[21:58:16] <pfred1> or you just using the built in one?
[22:11:20] <pfred1> apparently this system does not even have the parallel port driver enabled
[22:11:25] <pfred1> I did not know that
[22:16:34] <Cromaglious_> ParallelPortTest sees it and makes the driver step the drives
[22:16:57] <Cromaglious_> Par0 0x378
[22:17:26] <Cromaglious_> when I'm stepconf the run led lights up...
[22:19:33] <Cromaglious_> when I hit the test button the stepper makes noise and moves a bit
[22:19:55] <pfred1> hmmm maybe your timing for the drive is wrong?
[22:20:09] <pfred1> I know my drives are sensitive to that
[22:20:27] <pfred1> try to drive too fast and they get wonky
[22:21:14] <Cromaglious_> tried 2000,5000,10000,50000
[22:21:34] <pfred1> well it ain't that then
[22:22:06] <pfred1> because even my dog slow drives can do 5000
[22:22:49] <pfred1> well I run them at 5100 because 5000 is their cut off
[22:24:54] <pfred1> you're sure you have your step and direction lines right?
[22:25:20] <pfred1> because swapping them the motors don't run good
[22:25:57] <Cromaglious_> hmmm if pin 14 is high they don't work...
[22:26:11] <pfred1> that an enable line?
[22:27:49] <Cromaglious_> That's it.. pin 14 needs to be set unused and inverted
[22:28:00] <pfred1> ha ha!
[22:58:27] <Cromaglious_> 90mms on Y 90 on X 60 on Z
[23:08:12] <Contract_Pilot> Sup...
[23:20:36] <Cromaglious_> oops kernel panixc... haven't had one of those in awhile
[23:26:01] <jack_rabbit> That's what happens when you mess with 3 million lines of C code.
[23:43:21] <MacGalempsy> dang that took a while. those stupid trim-lok seals are a PITA to install
[23:50:59] <Cromaglious_> lets try this with a bi-directional Parallel port
[23:51:59] <pfred1> EPP?
[23:52:27] <pfred1> yeah there's one of those that LinuxCNC prefers
[23:53:08] <Cromaglious_> it's bi-directional now.. It was ECP, I'll change it to EPP next..
[23:57:03] <Cromaglious_> net xenable axis.0.amp-enable-out => stepgen.0.enable parport.0.pin-14-out
[23:57:35] <Cromaglious_> fixed it added parport.0.pine-14-out and it's using bi-directional printer port in bios
