12:47 AM Crom: watching oral arguments http://blog.californiarighttocarry.org/?page_id=2301
01:16 AM chopper79: howdy
01:42 AM Cromaglious_: hoydeeee
01:42 AM Cromaglious_: POS 3040... cables have all died withiin days of each other...
01:43 AM Cromaglious_: replaced Y and Z gotta find more for X
01:49 AM Cromaglious_: cable
02:10 AM Crom: ugh.... gotta find 25' 4c shielded 18awgish
02:16 AM Crom: hmm chart says 20awg is good for 4 amps with 4 conductors
02:16 AM Crom: 18awg is 5.6amps for 4 wires per cable
02:20 AM Crom: It'll be nice to get those JMC-motor 2nm integrated steppers DC bus 12awg 2conductors, then step,dir,alarm, and enable 8c 24awg cable woo hooo Cat 5!
02:21 AM Crom: anderson power poles for DC and RJ45 for control
03:02 AM archivist: when cables fail quickly look at bend radius, its too small
03:17 AM Deejay: moin
03:18 AM Crom: morning Deejay
03:19 AM Crom: archivist, could be... it's almost 2 years old though...
03:20 AM archivist: crom we could break cables in 30 minutes before we understood the bend radius design issues (was a dot matrix printer with not a lot of space)
03:20 AM archivist: mid 1980's
03:21 AM archivist: we went to Gore flat flexible, never had any more failures
03:22 AM archivist: it is why you see thin flexible pcb cable in scanners
05:03 AM XXCoder: dance like your microwave isn't watching
05:17 AM MacGalempsy: morning
05:17 AM XXCoder: hey
05:18 AM AndChat|234416: get a few milrs
05:18 AM AndChat|234416: miles in today?
05:19 AM AndChat|234416: XXCoder: do you use android?
05:20 AM XXCoder: little less than yeserday
05:20 AM XXCoder: then I had to do setup, which meant I had to leave cell alone as I worked on setup, dont want any irruptions
05:21 AM AndChat|234416: thats a good way to stick around in one spot for a bit
05:21 AM XXCoder: good thing i was getting bit sore from all that walking
05:21 AM XXCoder: it was great week for walking lol
05:22 AM AndChat|234416: was that me?
05:22 AM XXCoder: yep, and. lol
05:23 AM AndChat|234416: i switched from 4g to the wifi and thats when i got dq
05:23 AM XXCoder: so, what about android?
05:24 AM AndChat|234416: i rooted my tablet, but am trying to figure out what kind of stuff can be done
05:25 AM AndChat|234416: it had to be done because of a low power glitch put it in factory mode
05:25 AM AndChat|234416: got rid of a little bloatware
05:25 AM AndChat|234416 is now known as MacGalempsy
05:25 AM XXCoder: yeah thats biggest thing
05:26 AM MacGalempsy: wheni clear the ram it says there are 35 apps running in the background, but cannot find a good resource for the terminal commands to figure out what is running
05:27 AM XXCoder: many of em would be system apps
05:27 AM MacGalempsy: yeah. just want to go thru each to determine if they are spying on me
05:28 AM XXCoder: geez 2020 extrusions is little longer than I expected. which is good.
05:29 AM MacGalempsy: cool. you got all the stuff together now?
05:29 AM XXCoder: nah its fastest one
05:29 AM XXCoder: rest will take few weeks
05:29 AM MacGalempsy: dang. the day guy is trying to design a camper shell for his f150 out of 15 series
05:30 AM XXCoder: that is... insanely expensive
05:30 AM MacGalempsy: yeah. i think he is delusional
05:30 AM XXCoder: it'd be cheaper to build giant cnc router then make parts out of wood
05:30 AM MacGalempsy: i was like draw it up and have it welded
05:31 AM XXCoder: crash and lose $10,000 worth of 15 series
05:31 AM MacGalempsy: i was imagining it vibrating loose and falling apart on the trail
05:32 AM MacGalempsy: lol. he was trying to design it with $ketchup
05:32 AM XXCoder: yeah no :P
05:32 AM jthornton: morning
05:32 AM XXCoder: hey jt
05:33 AM MacGalempsy: i tried to tell him about fusion360, but it went in one ear and out the other
05:34 AM MacGalempsy: he started talking compound angles with the 15 series, and i just said,"cant wait to see the final product"
05:34 AM MacGalempsy: hi jt
05:35 AM jthornton: whats up this morning
05:35 AM XXCoder: geez
05:35 AM XXCoder: 15 series extrudsion made camper
05:35 AM MacGalempsy: killin time until the shift change at 060p
05:36 AM XXCoder: 3 am, friday yay heh
05:36 AM MacGalempsy: yea. lol. he started getting excited about custom brackets and the $$$ signs were flowing thru my day dream
05:36 AM MacGalempsy: texans and their trucks
05:36 AM XXCoder: yay milling tons of them parts for that guy
05:36 AM XXCoder: everything is big there, except one thing
05:37 AM MacGalempsy: brain
05:37 AM XXCoder: thats why they have big trucks
05:38 AM MacGalempsy: i rolled up in the farm truck on site and its a 2002 chevy 1500, and they were giving me shit
05:38 AM MacGalempsy: its all manual. only option is cruise control
05:38 AM XXCoder: they would coal roll all over my ford focus, thinking its other car they love to coal roll on
05:40 AM MacGalempsy: its a whole different life out here, for sure
05:41 AM MacGalempsy: kinda like beverly hillbillies meet breaking bad intersected by COPS
05:41 AM XXCoder: hillibillies, bad hillibillies, cops and bad cops
05:41 AM XXCoder: such great variety
05:42 AM MacGalempsy: COPS characters that are not cops
05:44 AM jthornton: got the little cover tester alive last night :)
05:44 AM MacGalempsy: they finally cut that check?
05:45 AM jthornton: took them 30 days of bumbling around to cut the 50% down check yea
05:45 AM jthornton: now 30 days later I'm almost done
05:46 AM MacGalempsy: sweet. how much does it weigh?
05:46 AM jthornton: 1.6 pounds to a PIZZA lunch!
05:46 AM MacGalempsy: just table top style huh?
05:47 AM jthornton: yea, bolted to a a roll around table
05:48 AM jthornton: just uploaded a few more photos
05:48 AM jthornton: http://gnipsel.com/images/cover-tester/husky-cover-tester-28.jpg
05:49 AM MacGalempsy: that looks slick
05:49 AM jthornton: thanks
05:50 AM jthornton: http://gnipsel.com/images/cover-tester/husky-cover-tester-21.jpg
05:50 AM MacGalempsy: that a plc?
05:50 AM jthornton: the push/pull cylinder on the left is on a 10psi regulator
05:50 AM jthornton: yea automation direct click $100
05:51 AM MacGalempsy: nice. the black thing is a sample cover?
05:52 AM jthornton: that is the actual cover
05:52 AM XXCoder: nice
05:53 AM XXCoder: more complete than last time I saw it
05:53 AM XXCoder: jt I got 2020 extrusions :D
05:53 AM jthornton: it tests that the pin is within a window, the bushing is present, the screw is far enough in and the keeper is not backawards
05:53 AM XXCoder: it'll give me plenty of room!
05:53 AM jthornton: what are you building with it
05:53 AM XXCoder: cnc electrics enclosure
05:53 AM jthornton: ah yea I remember now
05:53 AM MacGalempsy: what does the cutter cut?
05:54 AM jthornton: they will split one of the ejector pins so it leaves a sprue sticking out, if the cover passes all the tests it gets cut off
05:54 AM jthornton: if they pack it with the sprue they won't fit into the box
05:55 AM MacGalempsy: ah. great idea
05:55 AM jthornton: http://gnipsel.com/images/cover-tester/husky-cover-tester-20.jpg
05:55 AM jthornton: those were fun to make
05:55 AM jthornton: 5-40 threads in 1018
05:55 AM jthornton: see the texture in the grip area only
05:56 AM MacGalempsy: how many attempts?
05:56 AM jthornton: lol just one
05:56 AM MacGalempsy: prostyle :)
05:56 AM jthornton: http://gnipsel.com/images/cover-tester/husky-cover-tester-19.jpg
05:56 AM jthornton: that's how the cutter is mounted so you can move it in every direction to line it up
05:57 AM XXCoder: I see the wire fingers thingy whats it called? forgot
05:57 AM jthornton: panduit
05:57 AM jthornton: well that is who makes them
05:58 AM MacGalempsy: so you welded up the chassis and powder coated it?
05:58 AM jthornton: yea and no I just spray bombed it, too many nooks and Faraday areas
05:59 AM jthornton: and I don't have any light colored powder
06:01 AM XXCoder: fancy
06:02 AM jthornton: http://gnipsel.com/images/cover-tester/husky-cover-tester-08.jpg
06:02 AM jthornton: those pins were fun to make too
06:02 AM XXCoder: lathe work
06:03 AM jthornton: and a little on the mill to put a flat where the set screw holds it
06:03 AM jthornton: I didn't know if I would need to cut some off the right had pin so the prox would not see it but turns out it's ok
06:20 AM XXCoder: nice
07:12 AM XXCoder: jthornton: what ya think https://www.youtube.com/watch?v=nPyRT7eQhu0
07:17 AM jthornton: looks like a pretty good instruction video
07:18 AM XXCoder: yeah
07:20 AM jthornton: cutting the paint can with a hacksaw looks painful
07:31 AM CaptHindsight: someone could start a side business selling precut paint cans
07:33 AM jthornton: yea cut with a rotary plasma cutter
07:37 AM jthornton: nothing could be more fun than the green apple trots to go along with your cold
07:38 AM XXCoder: aw
07:39 AM XXCoder: oh yeah
07:39 AM XXCoder: I used estlcam to make first program for my machine
07:39 AM XXCoder: some weird thingy
07:39 AM XXCoder: just to see how effective it is.
07:40 AM XXCoder: http://dpaste.com/37FRSQC look at it
07:41 AM XXCoder: 3 min 5 sec approx
07:41 AM XXCoder: err 3 min 34 sec I mean :P
07:44 AM jthornton: is that mm? it's huge if inch
07:44 AM XXCoder: mm yeah
07:44 AM XXCoder: camotics suck.
07:44 AM jthornton: there is no preamble...
07:45 AM XXCoder: why why why why why is there is no damned realtime button??
07:45 AM XXCoder: and fast forward and slow down dont work
07:46 AM XXCoder: well it "kinda" works
07:46 AM XXCoder: but its max slowness is still looks like 10 times realtime
07:46 AM XXCoder: and dunno on preamble
07:47 AM XXCoder: it seems to explain what it makes, says what tool is needed, sets g90 spindle and set z to 5 mm above surface
07:47 AM XXCoder: then starts
07:48 AM XXCoder: what ya think of that thing heh
08:17 AM JT-Shop: I like the tiny bits left to hold it in place, did it do that automagicly
08:17 AM XXCoder: no, its easy to add tabs in it
08:18 AM chopper79: morning
08:19 AM XXCoder: hey
08:24 AM XXCoder: JT-Shop: interesting thing is that it might work as stand for something
08:24 AM XXCoder: use legs at ends and center for staff of something
08:24 AM XXCoder: lamp maybe lol
08:25 AM XXCoder: it has no real use, was just futzing in freecad sketch then exported it to dxf to make gcode
08:28 AM chopper79: Feeling biscuits and gravy this morning.
08:29 AM XXCoder: tired and bit dizzy
08:29 AM chopper79: That sucks
08:30 AM chopper79: I am still looking for a lathe as well. Not much luck right now on that end.
08:31 AM chopper79: Came across this one https://stlouis.craigslist.org/tls/6001756865.html
08:32 AM XXCoder: looks not bad to me, but ya know I dont know much about lathes lol nor its pricing so on
08:33 AM chopper79: I would be in for 1500 on that one personally. The price may be good, but I dont know.
08:33 AM chopper79: Emailed him with an offer so we will see if they respond with laughter.
08:33 AM XXCoder: heh heard sometimes they just offer random price
08:34 AM XXCoder: then sell to best offer to get rid of item
08:35 AM chopper79: Cash talks... I like showing up with a grand or so in $10.00 bills. Offer something low with a large fat stck of bills it plays mind games on some.
08:35 AM XXCoder: rolls of pennies. ;)
08:36 AM chopper79: Came across this one as well. https://chicago.craigslist.org/sox/tls/6044859284.html
08:37 AM chopper79: Old solid cast iron beast
08:37 AM XXCoder: my back is aching when I look at it.
08:37 AM chopper79: Same here.... one of the first things I though
08:37 AM gregcnc: you don't try to lift one of those by hand
08:38 AM XXCoder: nor ewith buddies heh
08:38 AM chopper79: Then I seen this and keep going back to it for some reason.... https://chicago.craigslist.org/sox/tls/6045865232.html
08:39 AM chopper79: Out of my budget though
08:39 AM XXCoder: new
08:39 AM XXCoder: basically new
08:39 AM gregcnc: what the
08:40 AM chopper79: Seemed like a fair price to me
08:41 AM chopper79: Like that the dials are on the fron of enclosure so manual use is still a great option.
08:41 AM chopper79: Either way.... wife would shoot me if I came home with that right now.
08:42 AM gregcnc: could be interesting, tell her it makes money
08:42 AM JT-Shop: nice little lathe
08:42 AM chopper79: I have...
08:42 AM JT-Shop: hmm no tool turret
08:43 AM chopper79: I seen that also
08:43 AM XXCoder: jt you considering making that thing? lol
08:43 AM XXCoder: its 1 cm in depth btw lol
08:43 AM gregcnc: x travel seems limited to put much gang tooling on there
08:44 AM JT-Shop: which thing?
08:44 AM XXCoder: that knobby thing
08:44 AM XXCoder: probably needs g21 to set metric
08:45 AM JT-Shop: no, just ran it in a sim
08:45 AM archivist: that sidney solid meaty nourishment, will still be running after the bomb is dropped
08:46 AM chopper79: archivist: I agree it is a solid machine
08:46 AM XXCoder: lol ok
08:46 AM XXCoder: I do plan to though I want to adjust depth
08:52 AM -!- #linuxcnc mode set to +v by ChanServ
08:53 AM gregcnc: today i learned about super nuts/bolts http://www.nord-lock.com/superbolt/multi-jackbolt-tensioners/nut-style-tensioners/introduction/
08:55 AM XXCoder: and that was last we heard og gregcnc
08:56 AM XXCoder: hmm
08:56 AM gregcnc: i saw this https://www.instagram.com/p/BRuGfsCgAxO/
08:57 AM skunkworks: those battery powered impact wrenches are awesome too.. It is so much easier to take junk apart now...
08:57 AM gregcnc: yeah, i don't know why I don't have one
08:58 AM XXCoder: giant hmm nut I guess heh
08:58 AM XXCoder: well nights
09:08 AM chopper79: Well my dog is looking at me with that face of are we going to get food or what. I guess that is my que to go eat something. Be back on after aw while.
09:57 AM chopper79: So I was doing some thinking. I am needing a lathe, but will be converting this lathe to cnc later down the road. I will need this lathe for machining ballscrew ends and other misc. turn work. The jobs I have coming up are all just one off parts so manual is perfect. About how much on average should one budget to turn a manual lathe into cnc lathe using servos and ballscrews?
09:57 AM chopper79: Just an exproximate
09:58 AM chopper79: I am figuring a couple grand at least personally.
10:12 AM seb_kuzm1nsky is now known as seb_kuzminsky
10:13 AM Wolf_: couple grand you might as well find a used cnc turning center to convert
10:13 AM malcom2073: +1. Couple Grand can get you a used working CNC center
10:13 AM malcom2073: No conversion needed
10:13 AM archivist: as the resident cheapskate, HOW MUCH!
10:13 AM chopper79: Kinda what I am thinking. As a used manual will be 1500 + and then add a coule grand for converting.
10:14 AM enleth: but using a CNC center for manual-style work is a PITA unless the control is really well optimized for that
10:14 AM Wolf_: yeah, when I say convert, I mean sell off the old control system parts and put lcnc on it
10:14 AM enleth: even lcnc isn't, out of the box
10:14 AM enleth: and getting it there is not easy
10:15 AM chopper79: I am seriously thinking about this one.. https://chicago.craigslist.org/sox/tls/6045865232.html
10:15 AM chopper79: The jog wheels are located in a great place for manual use. and down the road a lcnc conversion would onyl cost me about $400
10:16 AM chopper79: Just does not have a turret as JT mentioned.
10:16 AM chopper79: So a small gang tool setup would be the only thing I could do. Which would be fine if it had to be that way.
10:16 AM enleth: interesting, looks like it shares some iron with a manual machine
10:17 AM chopper79: appears that way
10:17 AM chopper79: 4000rpm spindle would be nice
10:18 AM chopper79: Would not need more then the 30" between centers either.
10:20 AM enleth: BTW, I was just looking at toothed belt pulleys to replace a multi-V belt on the ORAC and I had a pleasant surprise - taper lock pulleys are cheaper than I thought
10:20 AM chopper79: always nice
10:20 AM enleth: so I might just go for taper lock with the new transmission
10:22 AM enleth: a 30mm wide HTD 8M belt should be plenty enough even if I decide to do a motor upgrade later on
10:24 AM enleth: besides, it's just a matter of geting a new taper insert if the new motor has a different shaft diameter
10:24 AM enleth: and the old one can be re-used for another belt-driven machine with just a new pulley crown
10:26 AM Granath: Hi, Anybody know if it is possible to connect a contactor with 24v coil and 2.4w current directly to an Mesa 7i76E without using a relay? i'm using 24v to power the 7i76E
10:29 AM enleth: Granath: from the datasheet, "The 7I76Es outputs can drive loads of up to 350 mA."
10:29 AM enleth: not 100% clear if that's per output or shared and if per output, what the overall limit is
10:30 AM enleth: but I guess it's per output and should handle 100% utilization
10:30 AM archivist: does the board have protection diodes for relay driving
10:30 AM Granath: that's a good question
10:30 AM enleth: Granath: 24v 2.4W is 100mA, should be fine, but you might need flyback diodes
10:31 AM enleth: "The output driver chips used on the 7I76E have built in Zener diode clamps to clamp inductive turn-off (fly-back) spikes. This means that flyback diodes are not normally required on small (less than 60 mA) inductive loads. If high current inductive loads are switched or inductive loads are switched at high frequencies, they must have flyback diodes to limit power dissipation in the 7I76E's driver chips."
10:31 AM enleth: ah, there's a shared limit too
10:31 AM enleth: 1.4A per an output bank
10:32 AM enleth: there are thermal and overcurrent shutdown
10:32 AM enleth: *s
10:32 AM archivist: 2.4W is above that limit add protection diode
10:33 AM Granath: Ok, better safe then sorry
10:33 AM enleth: and maybe distribute the contactors among output banks (each set of 8 outputs is a single chip) if there are more than one
10:34 AM Granath: Ok, thanks for your help! i will add the diode and test if it works!
10:35 AM enleth: fun fact: I had to add flyback diodes to a couple "brake active"/"brake overriden" indicator lights I added to the bridgeport
10:36 AM enleth: the indicators died within 2-3 brake actuations otherwise
10:38 AM enleth: not surprising in hindsight, there are some very beefy solenoids in those brake assemblies - they must hold the brake open actively during machining, get *very* hot in no time and weigh a couple kg
10:42 AM Granath: You run a 7i76E for your Bridgeport?
10:43 AM enleth: 7i77 in the Bridgeport, 7i76E in the ORAC lathe
10:43 AM SpeedEvil: In a ballscrew 'lead ph' is the amount the nut moves per rev?
10:43 AM SpeedEvil: Is that an abbreviation?
10:43 AM Granath: Ok, happy with the 7i76E?
10:43 AM enleth: well, it works
10:44 AM Granath: I'm converting a Emco turn 120p and i'm building the electronic cabinet now with an Mesa 7i76E
10:44 AM enleth: it's a pity there's no 7i77E
10:45 AM Granath: Haha didn't sound too excited
10:45 AM enleth: I'm not a fan of the PCIe card solution
10:45 AM Granath: Ok, i was looking for a mesa solution that got me pins to do the encoder feedback from my closed loop steppers but couldn't find it in one card so i skipped that part for now
10:46 AM Granath: Ok, i was choosing between PCIe solution and Ethernet and i went with the 7i76E
10:46 AM enleth: same problem here, I'd be happy to add encoders to the ORAC
10:47 AM enleth: I guess I'll end up using the expansion connectors on the 7i76E to add a custom encoder adapter board
10:47 AM Granath: yeah, well i guess my stepper drivers are keeping track of loosing steps and i have an alarm output so it's good enough
10:47 AM Granath: ok that would be kinda cool
10:48 AM enleth: as for not using PCIe - 7i76E still has some space on the FPGA left, in theory I could make it kinda sorta autonomous that way
10:49 AM enleth: such as having a DRO even with no linuxcnc PC connected
10:49 AM Granath: aha ok,
10:49 AM Granath: not so helpful on the Emco no handles to turn :D
10:49 AM gregcnc: enleth toothed belt for the spindle?
10:50 AM enleth: gregcnc: why not? I've got a VFD to control slip and overload, don't have to burn the belt
10:50 AM gregcnc: noisey
10:51 AM enleth: you haven't heard the varispeed cadaver in my bridgeport
10:51 AM enleth: that's noisy
10:53 AM Granath: Lol
10:53 AM Granath: ok, bbl. thanks for your help :)
10:54 AM gregcnc: what does it give over the V belt?
10:55 AM enleth: what's "it"?
10:55 AM gregcnc: timing belt
10:56 AM enleth: doesn't slip on overload
10:57 AM gregcnc: won't the VFD stop in either case?
10:57 AM archivist: v bolts hardly ever slip until worn out
10:57 AM archivist: flat belts never grip fully
10:57 AM gregcnc: just doesn't seem worth the expense
10:59 AM enleth: I have to replace the belt and both pulleys on that lathe anyway, I'm not a fan of V-belts for some reason, and a toothed belt isn't much more expensive, so I might just as well try out one of those modern belt profiles to see how they perform as a spindle drive
11:00 AM gregcnc: won't be any different unless the belt was undersize to begin with
11:01 AM enleth: the original one is worn out and the pulleys have a lot of surface rust
11:01 AM enleth: the only rusty part of that machine for some reason
11:01 AM gregcnc: well they don't get oil or grease
11:02 AM chopper79: Testing the waters... Just sent my wife a message saying I spent $3500 on a lathe. I sit here waiting for a response or a hand to come flying through the screen and smack me.
11:03 AM Wolf_: lol
11:04 AM gregcnc: not worth it, you'll be latheless and still suffer the consequences
11:05 AM chopper79: Only way to know is the test
11:05 AM archivist: divorce now or later
11:06 AM enleth: gregcnc: don't toothed belts tolerate a little oil much better?
11:06 AM enleth: it's not a concern here, the new pulleys are going to have aluminum crowns anyway
11:07 AM enleth: but I think I've read about toothed belts being used in full oil immersion and tolerating oil splashes otherwise
11:07 AM chopper79: She usually does not have an issue when I do things like this. Key word is usually and it is more comman on blowing the budget by a couple hundred dollars not a couple grand.
11:12 AM chopper79: HAHA..... This women is awesome! She was fine with me doing it, so now I know I will change my budget to $2000 and be able to exspand my range of machines to look at and come under the approved $3500.
11:15 AM chopper79: Maybe... that is code when she uses a smiley face emoji thing for you better fing not have done that. Hmm. wifey mind games might be on the table now.
11:16 AM chopper79: tread lightly for a few
11:16 AM chopper79: need more data
11:17 AM archivist: or she is down at the car dealership looking at a new car
11:17 AM chopper79: Just got her one about 2 months ago.
11:17 AM chopper79: I guess she still could be
12:11 PM SpeedEvil: If I have an 8Nm stepper, and a 5mm advance lead screw, then the naive force is (8*2pi)/.005m = ~10000N?
12:13 PM archivist: there are some online calculators for leadscrew forces
12:16 PM SpeedEvil: seems straightforward, with energy per rev and advance
12:16 PM sync_: it's not really straight forward as you have to take the friction into consideration
12:16 PM SpeedEvil: yes - hence 'naively'
12:17 PM SpeedEvil: It's clear that a lead screw with a static maximum load a tenth of that'll snap
12:39 PM enleth: my impression is that above a certain scale (like, very small mechanisms), you should be more concerned about damaging some components with excessive force rather than about running out of force
12:47 PM gregcnc: it depends on what you want to break if things go bad
12:50 PM enleth: like the axis running up against the mechanical limits
12:53 PM CaptHindsight: broken Mazak M-5 CNC lathe $5K ? https://milwaukee.craigslist.org/tls/6042752076.html
12:54 PM gregcnc: sounds like dead encoder, but they probably know better(suggesting new control) and aren't saying
12:55 PM gregcnc: what a strange control with several windows running on winduhs
12:55 PM archivist: paint shows signs of a hard life
12:56 PM gregcnc: it ain't new at this point those are mid 80's?
12:56 PM CaptHindsight: http://www.mdsi2.com/
12:56 PM pcw_home: looks like its been tenderized
12:56 PM archivist: yes but the paint below the tailstock inside the bed
12:57 PM CaptHindsight: open closed source
12:57 PM CaptHindsight: " Unlike proprietary CNC controls, OpenCNC requires no proprietary hardware or motion control cards." got it
12:58 PM gregcnc: looks like it's been painted several times
12:59 PM CaptHindsight: it's a rustic layered effect
01:00 PM gregcnc: aren't most of them that blue/green color?
01:00 PM gregcnc: anyway would make a nice basement shop lathe if you fix the Z axis
01:01 PM CaptHindsight: https://minneapolis.craigslist.org/ank/tls/6014472287.html this isn't bad
01:02 PM CaptHindsight: specs http://www.abltechnology.com/en/machines/CNC_Lathes/3_Axis_or_Less/1999_Hitachi-Seiki_HT-23J_Seicos_Multi_EID109441
01:07 PM chopper79: I am holding off on a lathe for a bit more. Now that my budget has increased I can afford to look at more options. I am going to find a good lcnc conversion canidate. I am not going to just jump head first into a lathe as I have full access to a lahe currently. I just do not like moving all my parts from my place to another every day.
01:08 PM roycroft: i am still lathe shopping
01:08 PM roycroft: and still unhappy with what i'm finding available
01:08 PM chopper79: So now I can take my 3500 and add a bit more to the savings and buy a good solid canidate.
01:08 PM Loetmichel: re at home.
01:08 PM CaptHindsight: been a bad year so far even around here
01:09 PM chopper79: Same here
01:09 PM CaptHindsight: I can usually find something within 30 days
01:09 PM * Loetmichel states: yello cd in the player and free highway isnt exactly a recipe for fuel efficiency... at least now know that the Omega still goes 140mph :-)
01:11 PM enleth: chopper79: the best would be something with working servo drives but fried control
01:11 PM chopper79: I agree... that is my type of machine
01:12 PM chopper79: Can get them cheap enough and spend 400 on a mesa setup and pc and be good to go
01:12 PM enleth: chopper79: other than weird toolchangers, this is an almost drop-in replacement
01:13 PM chopper79: I keep findning lathes that are just beat up and I will end up converting to cnc anyway so why not just wait a little bit more and find a good canidate.
01:23 PM gregcnc: www.ebay.com/itm/232219512296 looks like water in the electronics cabinet
01:24 PM gregcnc: www.ebay.com/itm/232219512296 already has linuxcnc
01:26 PM IchGucksLive: hi
01:30 PM IchGucksLive: a nice day in germany
01:44 PM CaptHindsight: Ive seen more on ebay than CL lately
02:53 PM IchGucksLive: Gn8
03:31 PM os1r1s: Whats a good max_accel for a g0704 class machine with servos?
03:32 PM cradek: 20-30x the max velocity
03:34 PM os1r1s: cradek A max velocity of .57 would be 34.2, right?
03:41 PM cradek: sure, try it
03:42 PM cradek: although I'm not sure about your math, and that's an awfully slow max velocity
03:56 PM jdh: meters/s
03:57 PM cradek: your ini file has maxvel and maxaccel in inches/sec and inches/sec^2 if inch, or mm/sec and mm/sec^2 if metric
04:00 PM jdh: I can do 2+ ips on mine with steppers
04:20 PM jesseg: hrm, I'm writing a simple 2.5D cad program for Linux.. Any reason I shouldn't internally store arcs as x,y,start_angle,arc_length -- instead of start_angle stop_angle ?
04:22 PM jesseg: naturally, the arc_length would be positive or negative to indicate arc direction
04:35 PM JT-Shop: jesseg: have you seen my arc generator?
04:36 PM jesseg: JT-Shop, no, I have not!
04:36 PM jesseg: I made an arc generator once, called it a tesla coil :D
04:40 PM jesseg: JT-Shop, but I'd love to see your arc generator!
04:40 PM evilroot: https://drive.google.com/file/d/0B5fQTi1W868OTTZ6aXZ4Mkc1RUk/view?usp=sharing
04:40 PM evilroot: Arc Reactor did you say?
04:41 PM evilroot: https://drive.google.com/file/d/0B5fQTi1W868OMDZxc21EUDlvXzg/view?usp=sharing
04:41 PM evilroot: hehe
04:41 PM jesseg: I don't get it. Must be from a movie I haven't seen.
04:42 PM evilroot: Sheesh
04:43 PM JT-Shop: https://github.com/linuxcnc/simple-gcode-generators
04:46 PM jesseg: pretty sweet JT-Shop
04:47 PM jesseg: btw doesn't gcode support spiraling arcs as well with more than a single turn?
04:47 PM andypugh: Helical, but not spiralling
04:48 PM jesseg: oh ok
04:48 PM jesseg: I thought you could specify a second radius and have it spiral, never tried it though
04:49 PM jesseg: Could be handy for pocketing out a round area
04:49 PM andypugh: Maybe with a different G-code dialect
04:49 PM jesseg: yeah probably, or maybe it was just me thinking it was handy I'm thinking of :P
04:51 PM Apocalypsecow is now known as MolotovCocktease
05:41 PM Deejay: gn8
05:56 PM os1r1s: cradek Its in inches
05:57 PM os1r1s: jesseg jdh. I think that is in seconds. So .5 would be 1 inch every 2 seconds, or 30 IPM
05:57 PM os1r1s: If my math is right
05:58 PM jdh: right. really slow
05:58 PM jdh: ball screws?
06:02 PM os1r1s: jdh
06:02 PM os1r1s: jdh Yes. I'm still getting comfortable with this machine
06:03 PM os1r1s: I have tested it up to 200 IPM, but I backed it back down till I trust it
06:03 PM jdh: yeah, scary that fast
06:05 PM jdh: I tried 150. i think it is set at 90 now.
06:06 PM jesseg: are we talking open loop stepper machines?
06:08 PM jdh: mine is
06:08 PM jesseg: yeah steppers are scary at high speed in open loop
06:08 PM os1r1s: Is there a fault pin for an axis in linuxcnc that will halt/stop/pause it?
06:10 PM jdh: the table moving that fast is scary.
06:11 PM jesseg: that's for sure
06:11 PM jesseg: os1r1s, like on the printer port? I am not too familiar with linuxcnc
06:12 PM os1r1s: No. just in linuxcnc in general. I'm using mesa boards. I have a signal coming back from my motors signifying a fualt
06:12 PM os1r1s: fault
06:12 PM os1r1s: I just want to capture it appropriately
06:13 PM jesseg: oh I bet there is... but I have no clue
06:15 PM cradek: you'd hook that to the amplifier-fault input hal pins that motion has
06:16 PM cradek: http://linuxcnc.org/docs/2.7/html/config/core-components.html#_pins
06:16 PM jesseg: djdelorie, hey I was wondering if you ever had any success of plating through holes making PCBs
06:16 PM cradek: sorry I guess it's spelled amp-fault-in
06:16 PM djdelorie: nope
06:16 PM djdelorie: I typically use 28ga brass wire and a 0.014" drill (or something like that) - it's snug enough to stay put while soldering
06:17 PM jesseg: only minimal success for me, initial activation of the holes for electroplating is a real bear. The graphite powder and varnish sort of works, but not 100%. Electroplating is straightforward though.
06:18 PM jesseg: djdelorie, http://imgur.com/a/lFMb0
06:18 PM djdelorie: not bad!
06:19 PM jesseg: I did try some of those little through hole rivets. They work fine, but it's a lot of work to do a hundred and it gets expensive, but for a few it's OK.
06:19 PM djdelorie: I never found any small enough for my tastes, but I'm funny that way
06:20 PM Jymmm: I need some feedback... I need to put a 3.5" stove pipe thru the wall at a 45 degree angle. I have some 6"wide thin gauge aluminum flashing I thought about making to crescents (half moons), then overlaying them so they contour to the pipe. Think this would work for weatherproofing the hole in the wall? Anyone have a better idea?
06:20 PM Jymmm: two*
06:20 PM jesseg: yeah the smallest I found were like 0.024"
06:21 PM djdelorie: rivets wouldn't work on a board like this: http://www.delorie.com/pcb/inkjet/insanity_II.jpg
06:21 PM jesseg: came from Greece and were kind of expensive, like $20 for 200, delivered
06:22 PM jesseg: no kiddin' haha that is small
06:22 PM jesseg: or the finger is big
06:22 PM djdelorie: the two pads on the right are 0.1" pitch
06:22 PM jesseg: is that like about 0.5x0.25 ?
06:23 PM Jymmm: jesseg: djdelorie is a sleeping giant!
06:23 PM Jymmm: jesseg: so, big ass finger!
06:23 PM jesseg: Jymmm, gotcha :D
06:23 PM djdelorie: yeah, that's actually a sheet of plywood with a formica laminate that I did some cnc work on... ;-)
06:24 PM jesseg: haha
06:24 PM djdelorie: (the voices in the back of my head think that would be cool too, though...)
06:24 PM jesseg: what does that little board do?
06:24 PM djdelorie: mostly, though I just try to avoid vias anyway. More of a challenge that way
06:25 PM jesseg: yeah, but vias can be nice for high power/frequency applications
06:25 PM djdelorie: it's a test board with two oscillators on it, slightly different, producing an interference beat on an LED
06:25 PM djdelorie: yeah, but I usually end up going four layer for those, and... better to have them made at that point
06:26 PM djdelorie: it's a follow-up board to this one: http://www.delorie.com/pcb/smd-challenge/
06:26 PM djdelorie: I wanted to see if I could do CSP packages at home. I could :-)
06:27 PM jesseg: pretty cool alright
06:27 PM jesseg: What sort of soldermask do you use?
06:27 PM djdelorie: also was testing 5/5 rules with the UV etch. Er, Liquid Tin from MG usually
06:28 PM djdelorie: or I put more etch resist over it. I don't have real soldermask
06:28 PM jesseg: Oh, iron-on etch resist?
06:28 PM djdelorie: yup. I have a hacked laminator I use for it
06:28 PM jesseg: I got some of that but haven't tried it yet.
06:29 PM djdelorie: http://www.delorie.com/electronics/laminator/
06:29 PM jesseg: I also got some of that UV-cured solder mask stuff from China, I want to put a bright UV led or diode laser on my engraver to cure the solder mask, then do same thing with a second layer of different color for silkscreen/refdes
06:30 PM djdelorie: the trick with the laminator is this: make the film a few inches longer; tape it to a carrier page, tape tabs to the other end. Once the leading edge is in the laminator, use the tabs to hold the film UP and BACK
06:30 PM djdelorie: that minimizes bubbles
06:30 PM jesseg: oh gotcha... yeah bubbles=bad
06:31 PM jesseg: so it first touches right at the roller
06:31 PM djdelorie: yup
06:32 PM jesseg: I have this ancient cnc engraver that I modified and use to route out PCBs, or alternatively I just dip the FR4 blank in hot candlewax, then use the engraver to scribe away between traces - gives me smaller clearance - then etch.
06:33 PM jesseg: Also rigged it to drill and cut out pcbs
06:33 PM andypugh: Apparently the rivets go down to 0.6mm https://www.megauk.com/through_hole_rivets.php
06:33 PM jesseg: andypugh, yeah that's about what I got
06:34 PM andypugh: Does this look OK, or should it have more metal? https://imagebin.ca/v/3FvDfsOLUrKC
06:34 PM djdelorie: I picked up some engraving bits to try making pcbs that way, just before the cnc machine broke...
06:34 PM jesseg: djdelorie, blah that stinks :|
06:34 PM djdelorie: (my current thinking is that the mcus just lost their calibration data)
06:35 PM djdelorie: my last couple of repair sessions I was mostly working on the calibration subroutines, making them easier to use
06:35 PM jesseg: oh, so it just throws some errors, dj?
06:35 PM JT-Shop: not knowing the application it looks a bit on the light side
06:35 PM djdelorie: no, the motors jitter and shake like mad, instead of moving smoothly
06:35 PM jesseg: andypugh, hrm.. not exactly sure what I'm looking at
06:35 PM jesseg: djdelorie, brush type encoder servos?
06:36 PM djdelorie: brushless DC with encoders
06:36 PM jesseg: ahh
06:36 PM * JT-Shop calls it a night
06:36 PM andypugh: JT-Shop: I thought the same though the harmonic drive is only rated 50Nm and with big overhangs I would use the tailstock.
06:36 PM jesseg: Nighters JT
06:37 PM andypugh: It’s a casting to make my harmonic drive into a 4th-axis.
06:38 PM jesseg: andypugh, hrm, I dunno, it seems a touch on the light side.. but I'm sure it'll work till something gets dropped or bumped or crashed
06:38 PM andypugh: I was hoping that you would disagree with me :-)
06:39 PM djdelorie: "should it have more metal?" Duh, of course it should ;-)
06:39 PM jesseg: djdelorie, is it a shake like out of tune PID, (i.e. resonant) or like EMI getting picked up on encoder lines? (randomish)
06:40 PM djdelorie: "does it NEED more metal" is a different question ;-)
06:40 PM djdelorie: well, it was a shake that made me jump for the power cutoff
06:40 PM jesseg: andypugh, yeah, add a lot more metal, and while you're at it, cast the counterbalance for the other end of the table :D J/K
06:40 PM andypugh: The problem is that I can’t really expand backwards because the HD is there, unless I go to a diameter bigger than the mill table.
06:41 PM andypugh: I could go forwards up to the face of the D1-4 flange.
06:41 PM andypugh: But I can’t make the top-arch any thicker and still be able to access the cams.
06:42 PM jesseg: andypugh, well another way to look at it is try it as it is. If it gives you any problem, make another bigger one :D
06:42 PM andypugh: I don’t especially fancy making a pattern twice.
06:43 PM andypugh: That design is easy to make the pattern for, and easy to mould too.
06:43 PM djdelorie: have you tried 3d-printed patterns?
06:43 PM djdelorie: I've seen at least one filament specifically designed for "lost filament" casting...
06:43 PM andypugh: I don’t have a 3D-printer.
06:43 PM djdelorie: well, that would slow you down ;-)
06:43 PM zeeshan: cheap enough to find someone to 3d print
06:44 PM zeeshan: i do it all the time!
06:45 PM andypugh: Currently 6kg of iron, it would be quite a big print, it’s 8” tall.
06:45 PM jesseg: djdelorie, oh that kind of shake... yeah... my engraver startled me the other day. I had added some new code to the control program but I introduced a bug. The engraver which was made with stepper motors has pretty steep 2 start screws. Now with brushless DC motors, it really can move way too fast. There was no time to reach for the power cutoff it was just *bang*. Fortunately it's small and underpowered.
06:45 PM djdelorie: In my case, I blew the main power supply fuse
06:46 PM djdelorie: not sure if that was part of the cause, or part of the effect...
06:46 PM jesseg: yeah... well I have some halogen lamps in series with the power feed to the motor controller, so the bulbs just come on if the motor jams :P
06:46 PM djdelorie: I was pushing it pretty fast cutting a large pattern
06:47 PM djdelorie: I suspect my motors are stronger than my printer, though. "Jam" is the second most likely outcome ;-)
06:47 PM djdelorie: my machine is made of plywood
06:47 PM jesseg: oh yeah I remember seeing that, super cool.
06:48 PM jesseg: How does humidity affect your dimensional accuracy? :D
06:48 PM djdelorie: doesn't, the lead screws are metal
06:50 PM jesseg: andypugh, I actually want to build a wax printer head for 3d printing lost-wax casting items. Wax is cheap, *and* reusable.
06:50 PM andypugh: I am more inclined to make a sand printer to directly print moulds and cores.
06:50 PM jesseg: that's a pretty good idea
06:51 PM jesseg: actually... that's a splendid idea.
06:51 PM jesseg: almost do it like they do the laser fusing method. Put down a layer of sand, and spray some washable glue, put down another layer, etc.
06:51 PM andypugh: We have one at work.
06:52 PM jesseg: or just sinter the sand with laser
06:52 PM jesseg: one what?
06:52 PM jesseg: a 3D sand printer?
06:52 PM jesseg: How does it work?
06:52 PM andypugh: https://www.youtube.com/watch?v=Z8MaVaqNr3U&t=24s
06:54 PM jesseg: basically inkjet technology spraying binder on sand layers?
06:54 PM andypugh: Yes
06:54 PM malcom2073: Nice
06:54 PM malcom2073: That's pretty awesome
06:55 PM andypugh: Would be even more awesome if they let me use it for homework :-)
06:58 PM zeeshan: anyone know
06:58 PM zeeshan: something i can home brew to heat treat
06:58 PM zeeshan: im heat treating o1 steel
06:58 PM zeeshan: it decarbs if i dont give it any protection
06:58 PM zeeshan: causing me to grind for hours to get rid of the soft layer
06:58 PM zeeshan: i ordered atp 641 but its not here yet :[
06:59 PM andypugh: http://bodgesoc.blogspot.co.uk/2014/11/heat-treatment-furnace.html
06:59 PM zeeshan: i have a furnace!
06:59 PM andypugh: OK, so run a trickle of argon through it
06:59 PM zeeshan: andypugh: i forgot you got your phd in metallurgy :)
06:59 PM zeeshan: hmm
07:00 PM zeeshan: isnt decarb the same idea as a coke can?
07:00 PM zeeshan: the carbon starts bubbling out?
07:00 PM andypugh: Not sure that argon protects against decarburisation, though.
07:00 PM zeeshan: internet says you need a vacuum
07:00 PM zeeshan: or some sort of protective layer like atp 641
07:00 PM zeeshan: or stainless foil
07:00 PM andypugh: Heat in a molten salt bath?
07:01 PM andypugh: Can’t see a vacuum being better than inert gas.
07:02 PM andypugh: http://www.heat-treatments.co.uk/services/salt-bath-processes says that molten salt avoids decarburisation
07:02 PM zeeshan: NaCl? :)
07:05 PM zeeshan: i wish this damn atp641 arrived
07:05 PM zeeshan: im keen on finishing my knife :(
07:06 PM zeeshan: http://i.imgur.com/lAOECzr.jpg
07:06 PM zeeshan: ive been practicing quite a bit
07:06 PM zeeshan: but decarb is very noticeable with o1
07:09 PM zeeshan: i like your oven
07:09 PM zeeshan: i like the cnc use for wrapping the element :)
07:10 PM andypugh: “Austenitizing baths are cmprised generally of anhydrous Barium Chloride which begins to melt at approx 1760F with a working range of 1800F to 2400F. Neutrality of Barium Chloride operated over 2000F is my using a 2” x 12” carbon rod.” (Not clear on why they specify the rod size)
07:10 PM zeeshan: i only got nacl
07:10 PM zeeshan: but something tells me that'll produce chlorine gas =D
07:11 PM andypugh: http://parkthermal.com/Technical%20Bulletins/Heat%20Treating%20In%20Molten%20Salt%20Brian%20Reid.pdf
07:11 PM jesseg: andypugh, what kind of glue does that sand printer use?
07:12 PM andypugh: jesseg: I don’t know. Wish I did
07:12 PM andypugh: I suspect that Pro-Metal keep that secret.
07:12 PM jesseg: oh I bet they do LOL
07:14 PM zeeshan: andy
07:15 PM zeeshan: what if i put charcoal in the furnace?
07:15 PM zeeshan: wouldnt that naturally eat up the oxygen
07:15 PM jesseg: and also provide plenty of carbon to soak into the metal
07:16 PM XXCoder: hey zeeshan
07:17 PM zeeshan: im gonna try doing it to a scrap piece
07:17 PM zeeshan: i have
07:17 PM XXCoder: just futzing around with estlcam http://dpaste.com/37FRSQC lol
07:17 PM zeeshan: i hope this works
07:17 PM zeeshan: logically it makes sense
07:17 PM zeeshan: hi XXCoder
07:17 PM XXCoder: i see your knives got baked
07:17 PM andypugh: Time to go. 6am start tomorrow.
07:18 PM XXCoder: later andy
07:18 PM XXCoder: zeeshan: so whats up with knives
07:20 PM XXCoder: making em for customer or something?
07:20 PM zeeshan: no
07:20 PM zeeshan: for me
07:22 PM XXCoder: cool :)
07:23 PM XXCoder: you gave me a idea on making alum "knife"
07:23 PM XXCoder: decocative one
07:23 PM zeeshan: =D
07:23 PM zeeshan: When the metal is glowing red, the carbon behaves as if it's in a liquid and can therefore migrate around as it pleases. This is necessary for the hardening to occur but near the surface of the metal those unfaithful little carbon atoms would just as soon run off with any available oxygen-sluts it runs into (oxygen is soooo seductive) and they're lost then forever. We hate that.
07:23 PM zeeshan: rofl
07:23 PM zeeshan: i love this guys description of decarb
07:24 PM XXCoder: oh brother
07:26 PM XXCoder: I guess should not be exposed to air when glowing red?
07:27 PM roycroft: i shouldn't worry about it under those circumstances
07:27 PM zeeshan: yea XXCoder
07:28 PM roycroft: you would have other priorities
07:28 PM XXCoder: cool though I doubt I will ever try
07:28 PM roycroft: it wouldn't be cool
07:28 PM roycroft: that i can promise
07:29 PM XXCoder: lol
07:31 PM XXCoder: though still no idea what to make.
07:31 PM XXCoder: probably some fantasy knife or somethinbg
07:31 PM XXCoder: I'm definitely making zelda shield for fan of that game
07:32 PM XXCoder: wood one
07:32 PM XXCoder: cavendish is endangered
07:34 PM zeeshan: make anything
07:34 PM zeeshan: just do it!
07:35 PM XXCoder: did you preview the gcode I pasted link to? lol
07:35 PM zeeshan: no
07:35 PM zeeshan: i dont want to read gcode
07:35 PM XXCoder: made that thing for heck of it, will try it on machine
07:35 PM zeeshan: have been doing that every monday at work :{
07:35 PM XXCoder: know of better alternatives than camotics?
07:35 PM zeeshan: hsm !
07:35 PM zeeshan: :D
07:35 PM zeeshan: http://i.imgur.com/zGD8TBB.jpg
07:35 PM zeeshan: ive been making tons of parts lately
07:35 PM zeeshan: from the home business
07:35 PM XXCoder: becaue that sucks. im considering just installing linuxcnc on this computer, not to run machine but for previewing.
07:35 PM zeeshan: basic stuff
07:36 PM XXCoder: wow some random thing I probably will never know use for. lol
07:36 PM zeeshan: its part of a rescue jig
07:36 PM zeeshan: i think.
07:36 PM zeeshan: :p
07:36 PM XXCoder: I got 2020 extrusions ready for building cnc electrics box :D
07:36 PM XXCoder: too bad rest of parts will take 500 years to get to here.
07:37 PM XXCoder: checking hsm
07:37 PM zeeshan: you get it free with fusion
07:37 PM zeeshan: no reason not to use it
07:37 PM zeeshan: it even has a linuxcnc postprocessor in it
07:37 PM XXCoder: ahh it dont run too well on my vmc
07:38 PM zeeshan: hmm
07:38 PM zeeshan: it says my atp 641 has been delivered!!!!!!!!!!!!
07:45 PM XXCoder: and whats it? heh
07:46 PM zeeshan: decarburization protection
07:46 PM zeeshan: sweet
07:46 PM zeeshan: now i can heat treat!!!!!!!
07:46 PM zeeshan: ill do it tomorrow morning :D
07:46 PM XXCoder: https://www.eliomotors.com/wheel-fairings-answers/?utm_campaign=Three%20Wheel%20Blog
07:46 PM XXCoder: I like classic look but dunno lol
07:48 PM XXCoder: man spam is getting creative on trying to get me to click url
07:48 PM jdh: XXCoder: I have run across several windows based gcode previewers
07:48 PM _methods: cimco
07:49 PM XXCoder: one is "fine here is your invoice you fducking thief" (url) and other is "your apple id is used on iphone 4 click to confirm"
07:49 PM XXCoder: jdh: yeah? using linux, though im sure in least one would work in wine.
07:49 PM jdh: probably
07:49 PM R2E4_bevins1: godd evening, mornin, afternoon
07:52 PM XXCoder: hey
08:24 PM R2E4_bevins1: remapping coming along........
08:24 PM R2E4_bevins1: unlike googlemapping, it is quiote complicated.
08:25 PM roycroft: an hour and a half ago ebay were going to call me in 14 minutes
08:25 PM R2E4_bevins1: Will test out my programming skillz this weekend....
08:25 PM roycroft: they have not yet called
08:25 PM roycroft: and i'm having a cable tv appointment situation now
08:25 PM roycroft: i have to pee
08:25 PM roycroft: and i know the phone will ring the instant i do so
09:05 PM Crom: replaced X,Y,Z stepper cables, got X,Y,Z home working... X is halleffect, Y in induction, Z is NO switch with capacitor across the contacts
09:07 PM Crom: need to slow down y homseekvel.. so it stops crashing into the sensoe
09:08 PM yasnak: so i can connect to pptp vpn locally not not externally, firewall configured correctly (verified by sonicwall) and server shows no errors. the fuck. i love tech sometimes.
09:08 PM yasnak: oops
09:09 PM Crom: roycroft, it's called tinkle time
09:18 PM XXCoder: wiki on linuxcnc is oooold
09:23 PM yasnak: https://www.youtube.com/watch?v=NjgcqZH8rt4
09:23 PM yasnak: nothing like blowing $10.00 a shot
09:24 PM gregcnc: material cost?
09:24 PM yasnak: yessah
09:24 PM XXCoder: what material?
09:24 PM yasnak: this is natual peek
09:24 PM yasnak: otherwise run 30% CF peek
09:24 PM yasnak: that shit sucks
09:25 PM XXCoder: whats stuff its making for heh
09:25 PM yasnak: suture anchors, mainly for double-row surgery
09:25 PM gregcnc: i was guessing peek. dang and they gizmo probably sell for 10x that
09:25 PM yasnak: rotator cuff
09:25 PM yasnak: yeah the 10Kg cans cost some pathetic 200k each haha
09:26 PM gregcnc: wow medical is the place to be
09:27 PM yasnak: its tough to get there, but one you do all the quality system/regulatory and so on its worth it
09:28 PM gregcnc: i just wrote an excel sheet to write lathe code for a family of similar items. it works so now to add some c axis features
09:28 PM XXCoder: after getting there sits like license to print money eh
09:28 PM XXCoder: *its
09:28 PM yasnak: but its so much different from job shop, you have almost more paper-pushing office workers then machinists. we currently have more office staff then actual machinists including everyone in assembly, deburring, qc, packaging, operators and such
09:29 PM yasnak: yeah the paper-pushing...FDA has audited us twice in last two years. we pissed someone off
09:31 PM gregcnc: patented products mostly? or is there a market for common medical stuff because people won't do the papaers?
09:32 PM os1r1s: yasnak What med device company do you work for?
09:37 PM XXCoder: about paperwork vs workers http://www.lab-initio.com/screen_res/nz354.jpg
09:48 PM yasnak: a company ;)
09:48 PM yasnak: why?
09:54 PM XXCoder: yas, I bet its interesing place to work for machinists
09:54 PM XXCoder: though dunno if good match for me LOL
09:54 PM XXCoder: I love to read during long runs
09:54 PM XXCoder: this week not so much as I had to run cell and old machine, and it needed a lot of walking :P
09:55 PM XXCoder: oh look usa leadership offended yet another ally
09:56 PM XXCoder: sad that its boring news now
09:56 PM jdh: LinuxCNC
09:57 PM roycroft: i thought merkel was going to punch him today
09:58 PM roycroft: so my plan worked out great
09:58 PM roycroft: i to make a bunch of caster mounting pads with threaded studs sticking out the bottom
09:59 PM roycroft: usually when i do stuff like that i get some threaded rod and cut it up and weld it to the pads, but i had to do 96 of them and that seemed like a lot of tedious work
09:59 PM XXCoder: bah im too lazy to do anything
09:59 PM roycroft: so instead i got a box of 100 cup bottom slotted set screws, drilled and tapped the pads, screwed them in and welded them in place
10:00 PM roycroft: if i had a cnc mill the drilling and tapping would have gone way faster
10:03 PM yasnak: we're not arthrex is that matters, but we have uhhh, a history with them ;)
10:03 PM yasnak: a not so good history if anything haha
10:22 PM {HD}: Anyone ever taken apart one of those 1.5kw, 2.2kw, 3kw generic chinese spindles?
10:23 PM XXCoder: im sure someone did but dunno if any ever posted
10:26 PM yasnak: why?
10:26 PM yasnak: is there actually gerbils inside them?
10:28 PM XXCoder: no no too big for spindle
10:28 PM XXCoder: its repeated tracks of ant track rings
10:28 PM XXCoder: thats why its so strong
10:30 PM os1r1s: Do min_limit and max_limit for axes refer to the machine coordinates (G53) or the offset coordinates (G54)?
10:32 PM XXCoder: machine
10:32 PM XXCoder: its in stepconf or HAL file correct?
10:33 PM os1r1s: XXCoder So I keep getting this move would exceed positive limits and I can't seem to figure out why
10:33 PM XXCoder: look at graphics
10:33 PM os1r1s: The machine can cut. I just added homing switches
10:33 PM XXCoder: is any of loaded program path outside bounds?
10:33 PM os1r1s: Oh, could be
10:33 PM XXCoder: home switches set machine zeros correct?
10:33 PM os1r1s: Its got that default linuxcnc toolapth
10:34 PM os1r1s: XXCoder Yup
10:34 PM XXCoder: or is it configured say -400 to 400
10:34 PM os1r1s: I've got X configured for example 0-19
10:34 PM os1r1s: 0 min, 19 max
10:34 PM os1r1s: And 0 is where the homing switch is
10:34 PM os1r1s: The weird thing is I can jog there. I just can't issue a move command
10:34 PM XXCoder: so it travels there, sets machine x home there
10:35 PM os1r1s: Yep. Does it correctly for X,Y, and Z
10:35 PM XXCoder: hmm if I recall right some commands refuse to work when machine is not homed yet
10:35 PM os1r1s: This is after I home the machine
10:36 PM XXCoder: so it was homed
10:36 PM XXCoder: you can jog it around the interior workspace
10:36 PM os1r1s: So I put in tool 1. set the workpiece coordinates. Tell it to put in tool 2, and it complains about exceeding a limit
10:36 PM os1r1s: But I can jog there no problem
10:36 PM XXCoder: but you cant issue go or g1?
10:36 PM XXCoder: *g0
10:37 PM XXCoder: did it say what axis is behind limit
10:37 PM os1r1s: Honestly it could be any of them. I've seen it say X, Y and Z
10:37 PM XXCoder: hmm
10:37 PM os1r1s: Its really weird
10:38 PM XXCoder: so m6 t2 and it errors out
10:38 PM os1r1s: But I can jog there which it should not let me do if I am exceeding the limits
10:38 PM os1r1s: Correct
10:38 PM os1r1s: M6 T2 or M6 T3 error out
10:39 PM XXCoder: I wonder if its related to t1 tool length
10:39 PM XXCoder: if it moves while t1 tool comp is still on it might try to move up too far
10:40 PM os1r1s: T1 tool length is 5.956
10:40 PM os1r1s: T2 tool length is 4.223
10:40 PM XXCoder: I dont use tool length on my linuxcnc sadly so hard to help heh
10:41 PM os1r1s: Its strange. I should be able to do this ...
10:42 PM XXCoder: can you check if its still on tool comp when its moving for tool change?
10:42 PM XXCoder: if so, try add gcode to turn that off
10:42 PM XXCoder: (before m6 t2)
10:42 PM XXCoder: I cant recall what tool comp turjn off is... g80?
10:42 PM Wolf_: I haven’t tried tool length either, I handle that in the cam
10:43 PM os1r1s: I think G49 turns it off
10:43 PM XXCoder: myself I just touch whatever tool is on and set z to it
10:44 PM XXCoder: Wolf_: how? I know cam tend to have tool length but its in terms of how much cutting part there is so it can dermine cuting paths
10:45 PM Wolf_: oh wait, yeah, I’m stuck doing touch offs
10:45 PM os1r1s: I'm trying to avoid doing touchoffs
10:45 PM Wolf_: when the x2 is done then I’ll be dealing with the tool length offsets
10:45 PM chopper79: Evening
10:46 PM XXCoder: I dont use that at work thankfully
10:46 PM XXCoder: but my home machine is manual tool change, and not toolholder type
10:46 PM os1r1s: And honestly it all works. Except moving to the tool change locations
10:46 PM XXCoder: so length setting is meaningless
10:48 PM XXCoder: os1r1s: so you use common reference point like I do at work eh
10:48 PM os1r1s: XXCoder That's what I'm trying to get to
10:49 PM XXCoder: ya did you look at gcode if there exists g49 before m6t2?
10:49 PM os1r1s: I'm calling it directly from the MDI
10:49 PM XXCoder: and do it slowly in case heh
10:49 PM os1r1s: So it doesn't. But it seems kind of concerning to turn it off with the tool still in
10:51 PM XXCoder: yeah thats why i said go slowly, I dont recall when typical progam at work does
10:51 PM os1r1s: I wonder if its some of the init parameters in that stock linuxcnc program
10:52 PM Crom: I have delrin clamped down to the table to start on a tool height sensor
10:52 PM XXCoder: Crom: I'd love to have tool length automated
10:53 PM Crom: Trying to figure out how to combine Y home and Probe in
10:53 PM os1r1s: XXCoder What size machine are you doing it on?
10:53 PM Crom: save a pin
10:53 PM XXCoder: 500mmx300mm router heh
10:53 PM os1r1s: Ahh, ok
10:53 PM XXCoder: not very large
10:54 PM Crom: 270mm x 372 usable
10:54 PM Crom: on a 3040
10:54 PM os1r1s: I actually have a tool offset sensor.
10:54 PM os1r1s: Just not installed
10:54 PM os1r1s: But right now Tool 1 is a Haimer
10:54 PM XXCoder: cell I run have fancy laser tool measure but we dont use it to set tool length
10:54 PM XXCoder: I guess its just not accurate enough for that
10:55 PM XXCoder: but close enough for "hey tool is fuked up somehow!"
10:55 PM os1r1s: XXCoder We have ones like that at work too. It measures length, wear, and all
10:55 PM XXCoder: yours seem more fancy
10:56 PM Crom: welp bbiaw taking care of Honey Do this, and this, and that, and this other thing
10:56 PM os1r1s: XXCoder The coolest one we have at work is a Chiron
10:56 PM XXCoder: later
10:56 PM os1r1s: It autoloads itself and runs jobs automatically
10:56 PM XXCoder: os I have to say its robodrill haas lol, its not most fancy but damn is it cool lol
10:56 PM XXCoder: it runs off 220v
10:57 PM XXCoder: but honestly most advanced machine is d500, its 5 axis and all that
10:57 PM XXCoder: cell I run is most expensive though, what with train and 2 machines and all lol
10:58 PM XXCoder: we have way too many machines for number of machinists we have, and we arent hiring bleh
10:58 PM XXCoder: out of 11 cnc machines added, only 4 is running now. our mechinic is so busy.
10:59 PM os1r1s: That sucks
10:59 PM XXCoder: 2nd shift (shift im on) is way understaffed. 4 machinists and 2 lathe
11:00 PM XXCoder: when i started there was 7 mill and 5 lathe workers
11:00 PM XXCoder: 1st shift is still fill, weekend has slightly more people
11:03 PM os1r1s: In your var file, do you have 5213?
11:03 PM {HD}: I wanted to see if I could put a larger collet in the spindle.
11:04 PM os1r1s: XXCoder ^
11:04 PM XXCoder: dunno, my linuxcnc computer is powered off though i was oplanning on running gcode I just made hmm
11:14 PM XXCoder: will check as soon as it boots
11:29 PM xxcodercnc: hey os1r1s
11:30 PM xxcodercnc: what did you want me to look for in var?
11:30 PM os1r1s: xxcodercnc It was G92 offsets
11:30 PM os1r1s: I had set them and linuxcnc saved it
11:30 PM os1r1s: Its line 5213
11:30 PM xxcodercnc: ah mines 0
11:31 PM xxcodercnc: was it solved?
11:31 PM os1r1s: Yep. But if you set something with G92, then it remembers it
11:31 PM os1r1s: Yep
11:31 PM os1r1s: That fixed it
11:32 PM xxcodercnc: ahh so solution was set it back to 0, or turn off g92?
11:32 PM os1r1s: Use G92.1
11:32 PM xxcodercnc: ()before tool change)
11:32 PM os1r1s: Which zeroes them out
11:33 PM os1r1s: I just had to do it once
11:33 PM xxcodercnc: nice
11:33 PM os1r1s: Before I had h0ome switches I was trying to use G92
11:33 PM xxcodercnc: well now to test gcode i made lol
11:35 PM os1r1s: So now I just have to figure out why my height gauge is not correct
11:37 PM xxcodercnc: the 2 rod thing that holds either dial test indictopr or that accurate flat thing
11:37 PM xxcodercnc: tend to be on Surface?
11:37 PM os1r1s: xxcodercnc This thing ... https://www.tormach.com/store/index.php?app=ecom&ns=prodshow&ref=31761&portrelay=1
11:38 PM os1r1s: Not that specific one, but one like it
11:42 PM xxcodercnc: looking
11:43 PM xxcodercnc: oh thats duifferent type
11:47 PM os1r1s: So
11:47 PM os1r1s: I use that to set all the tool lengths
11:47 PM os1r1s: Then plug them into linuxcnc
11:48 PM os1r1s: Then when I try to compare in the machine, its off by a bit
11:48 PM os1r1s: At least between one of my tools and the rest
