[02:50:17] <_abc_> .
[02:51:35] <_abc_> I have a thread/drill question, trying to mate an unexsitium (here) imperial thread with a metric device. I am willing to destroy or epoxy the imperial thread in the process. This is a drill/hack question:
http://82.76.171.111:8881/mypaste/d371206174c0aff5a16e/0threads-drills-metric-imperial.txt table of metric and imperial screw threads.
[02:51:53] <Cromaglious> when is linuxcnc gonna get a pathpilot ish interface...
[02:52:03] <_abc_> Questions: The thread I need to mate (and destroy) is 1/2in 20tpi which seems to be fine pitch not standard. Correct?
[02:52:25] <Cromaglious> correct 1/2-13 is NC
[02:52:54] <_abc_> The other option is to get an arbor adapter which has the necessary thread and machine the arbor. That can be hard since the arbor is long and hardened and I will need to detemper it, thread it, cut to length etc.
[02:52:54] <Cromaglious> lemme double check
[02:53:06] <_abc_> See the table, it is correct.
[02:53:57] <_abc_> 1/2-12
[02:54:23] <_abc_> Note the table comes from my digital caliper's back and that was made in China. Could be 12+/-1 tpi >;)
[02:54:53] <_abc_> (I have a tape measure from China which is 98% accurate - 6mm off at 3m max length is NOT GOOD)
[02:55:52] <_abc_> So the table gives the thread bottom i.d. too, which is useful, because I will jam an axle machined down to that measure into the thread and glue it in place while centering it dynamically in slow rotation.
[02:56:10] <_abc_> Any hints on how (not) to do this?
[02:56:10] <Cromaglious> yep UNF is 1/2-20 and UNC is 1/2-13
[02:56:18] <_abc_> so 13 or 12?
[02:56:28] <Cromaglious> 13 TPI
[02:56:39] <_abc_> Damn caliper ;)
[02:57:20] <archivist> http://www.bodgesoc.org/thread_dia_pitch.html
[02:57:21] <_abc_> Nope, wait. 1/2-12 is UNF (not UNC)
[02:57:38] <Cromaglious> The metric thread is the male or female?
[02:57:46] <Cromaglious> UNF is 1/2-20
[02:58:11] <_abc_> The metric thread is male. The imperial female thread will be sacrified ;)
[02:58:41] <_abc_> I'm a metric guy and imperial threads drive me insane.
[02:59:03] <Cromaglious> hmm make an adapter... metric thread outside and imperial inside
[02:59:22] <_abc_> Can't, the male is too large, not enough 'meat'
[02:59:46] <_abc_> This is for a very light duty chuck. The chucks come in imperial thread sizes for unfathomable reasons, I am in Europe...
[02:59:59] <_abc_> Our own chucks, locally made and China, are of course metric threaded
[03:00:16] <Cromaglious> Jacobs taper on most of mine
[03:00:24] <_abc_> But the hw store has cheap "compatible" chucks for various hand drills etc
[03:00:44] <Cromaglious> chuck for a drill motor
[03:01:12] <_abc_> Including the snap in tool holder which this one is for. So the chuck has a 1/2-20 thread in the back and the adapter arbor for snap in tool has a mating thread and a hardened shank with the snap in 'ears'
[03:01:32] <_abc_> And I need to repurpose it for my mostly metric thingys.
[03:02:19] <Cromaglious> ugh.. yep... detemper, remachine, retemper...
[03:02:26] <archivist> domestic drill chucks are mainly imperial get used to it
[03:02:37] <Cromaglious> nite all
[03:02:40] <_abc_> Nono. Epoxy. This is a $5 chuck. How much time do you think I will invest.
[03:02:45] <_abc_> Good night and thanks.
[03:03:00] <archivist> you have already wasted time in here :)
[03:03:12] <_abc_> It's cheap and I'm drinking coffee.
[03:03:49] <archivist> and you started on this mount a chuck project a week ago or more
[03:04:02] <_abc_> No this is another. I solved the previous one ;)
[03:04:13] <archivist> lies
[03:04:21] <_abc_> These cheapies keep turning up so it's worth a few words on a forum
[03:04:23] <_abc_> No lies.
[03:05:11] <_abc_> I wonder if anyone ever tried to convert a SDS tool shank pickup to diy cnc tool changer mode
[03:05:28] <_abc_> Just as a general discussion question ;)
[03:07:28] <_abc_> Has anyone got a link to an exploded view or cross sectional drawing of the female part of a SDS tool shank pickup?
[03:07:59] <archivist> SDS is a sloppy fit, dumb idea
[03:08:24] <_abc_> Well compared with proper Morse or ER collets yes, but I am asking this, not about Morse or ER ;)
[03:08:49] <_abc_> SDS and SDS plus are not compatible?
[03:08:57] <archivist> they cannot be used in a cnc side cutting
[03:09:14] <archivist> simply put NO
[03:09:15] <_abc_> Probably depends on whether someone shimmed them a bit or not
[03:09:40] <archivist> no it is sloppy for a reason, the hammer action to rear
[03:09:59] <_abc_> I am aware of that. Also that there should be a way to cancel that with mods.
[03:10:08] <_abc_> Hammer cnc would be a new thing.
[03:10:35] <archivist> just plain silly thinking sds could be used
[03:12:34] <_abc_> Then suggest what machining could be applied to a SDS adapter shank
http://www.terapeak.com/worth/sds-plus-shank-3-8-socket-nut-impact-driver-drill-chuck-adaptor-drive-bits/321913889773/ after detempering to make it work in another kind of collet. Note I had an axle machined before, smooth, for such purposes, to be mounted in lathe/drill chuck of larger diameter.
[03:13:01] <_abc_> SDS uses 2 drive splines and 2 balls to retain the tool, right?
[03:15:20] <_abc_> Hm I see 1/2-20 UNF thread is also used in various pipe fittings. Would it fit the chuck or would there be other tricks too? Like subtly different thred profile?
[03:16:16] <_abc_> http://festoolownersgroup.com/other-tools-accessories/new-fesboschtool-drills-lol/?FOGSESSID=a389fsbtioop0m8pjg0oj51tq6&action=dlattach;attach=210790;image finally
[03:17:36] <_abc_> I assume the circular section ring near '5' label on the tool shaft is a C spring which retains the tool loosely and centers it? Or is it an o-ring serving the same purpose?
[03:18:23] <_abc_> Judging by the hatching pattern it is metal.
[03:18:37] <_abc_> Is it called hatching / hashing ?
[03:19:04] <archivist> hatching
[03:19:08] * _abc_ 's language uses the word taken from French 'hachure'
[03:24:16] <_abc_> Well next time I find a SDS pickup hand tool dead on my premises I will try surgery to see how the SDS pickup can be tightened a bit to make it more CNC tool changer and possibly side cut friendly.
[04:06:22] <cctvs> hello :-)
[04:13:52] <_abc_> So a SDS chuck differs from a tool changer chuck "mostly" in tolerances, lack of taper for centering, and location and purpose of lock balls...
[04:21:03] <gonzo_> that is a big 'mostly'
[04:21:11] <_abc_> Yep
[04:22:48] <_abc_> However, when there is a will...
[04:23:02] <_abc_> And time (haven't got any for this) and tools (maybe)
[04:23:46] <archivist> cheaper, more accurate to do something properly
[04:24:02] <_abc_> Depends where you are and whyt your audience is.
[04:24:07] <_abc_> *what
[04:24:17] <archivist> sds is designed for idiot builders, not cnc
[04:24:23] <_abc_> True.
[04:24:34] <_abc_> SDS+2 should be a SDS mod aimed at cncers ;)
[04:24:44] <archivist> trying to bend its use is even more silly
[04:25:25] <_abc_> Yes but... as I said, depends on audience etc
[04:25:51] <archivist> selling shite to idiots is fraud
[04:25:55] <_abc_> Drill shank standard lengths depend on diameter group, right?
[04:26:25] <_abc_> archivist: not really, if the idiots are briefed, willing, and the price is right (low). Also this is mostly for diy not sale
[04:26:33] <_abc_> diy by myself and others though
[04:27:40] <archivist> morse taper is a similar price and works
[04:27:47] <_abc_> Not "similar price" here
[04:28:07] <_abc_> There are market discrepancies caused by gouging and idiots not being able to read / apply internet information
[04:28:20] <_abc_> Also there's a large pool of broke people with time on their hands.
[04:28:26] <archivist> a collet is a few pounds
[04:28:34] <_abc_> A few pounds is too much here.
[04:28:41] <archivist> time cannot make sds work well
[04:28:45] <_abc_> Also the spindle to hold it is too dear for most.
[04:55:34] <Patang> After upgrading from 2.7.3 to 2.7.6 my DRO's (gmoccapy) shows something completely wrong. Can't really say what they show, but I guess this might be enough info for someone to tell me if they have heard of anything similar?
[05:09:59] <enleth> I need to replace configuration memory batteries in the bridgeport - somehow it zeroed out the "maximum following error" parameter while keeping everything else sane enough that it managed to turn on and initialize
[05:10:29] <enleth> At which point people started calling me asking why would it error out on a "gross positioning error" on any attempt to move it
[05:10:59] <enleth> It was a fun problem to debug, though - I didn't think of this at first
[05:12:40] <enleth> Suspected the encoder interpolators at first, that wouldn't be the first time they crapped out, but that shouldn't have affected all three without causing a more generic internal error first
[05:14:03] <enleth> Then it turned out it does move - at feeds less than 100mm/min, where apparently the servos are capable of keeping up with no detectable following error
[05:36:20] <jthornton> morning
[06:29:58] <Tom_itx> morning
[09:15:41] <MacGalempsy> morning
[09:17:13] <archivist> to stop your floor blowing away
http://www.ebay.co.uk/itm/142109712121
[09:25:05] <Simonious> eh.. my uncle and grandfather do a pretty good job of holding the floor down already. ;)
[09:25:34] <MacGalempsy> looks like a fun one to move
[09:26:06] <MacGalempsy> anyways, im off to check out the auction previews. hopefully, the bids prices stay low!
[12:49:54] <plpower> hi
[13:12:34] <gregcnc> hello...is there anybody in there?
[13:12:46] <plpower> wgere
[13:12:51] <plpower> where
[13:13:11] <plpower> there is always a bug in the mashine
[13:13:22] <plpower> so yes its there
[13:14:24] <plpower> gregcnc: ask we see if we can help
[13:14:35] <gregcnc> MAYBE i CAN HELP YOU
[13:14:39] <gregcnc> oops
[13:14:43] <plpower> if needed
[13:15:37] <plpower> oh tht woudt be good is it still posoble to update 10.04 Lcnc 2.5 without depencie access
[13:16:40] <plpower> ok i only got 2days to go i nthis busineess
[13:16:50] <plpower> monday the ownwer will be back
[13:18:56] <gregcnc> I don't know enough about linux to help with that, probably need root to install almost anything
[13:18:57] <plpower> im off lunch is ready
[13:19:37] <plpower> gregcnc: 10.04 is depreted no depencies available
[13:20:08] <gregcnc> oh I did it in march maybe
[13:20:09] <plpower> bye
[13:39:11] <nikre> i have 5 axis breakout board with parallel interface. i will connect this to 2 6560 and 1 6600 stepper controllers. why do i need the 12v power source connected to the breakout board when i power up each stepper controller invidividually?
[13:39:24] <nikre> this one:
http://www.ebay.com/itm/US-Ship-5-Axis-MACH3-CNC-Breakout-Board-Interface-for-Stepper-Motor-Driver-/231617048089?hash=item35ed73ae19:g:d6AAAOSw3ydVmzqq
[13:44:24] <nikre> is there an autoleveling feature on linuxcnc?
[13:49:45] <FloppyDisk525> 12vdc is for your I/O and is 'propbably' opto isolated from 3.3v or 5v from the parallel port.
[13:50:27] <FloppyDisk525> While your steppers drivers are powered separately, you still need to get them step and direction signal.
[13:50:39] <FloppyDisk525> Which comes from the PC through the BOB (break out board).
[13:50:56] <FloppyDisk525> If you want limits and such, 12vdc or 24 vdc is how you work that.
[13:51:09] <nikre> Thank you FloppyDisk525
[13:51:34] <nikre> how about autoleveling? i plan to mill pcb's
[13:51:54] <FloppyDisk525> I actually have that card on a test stand, however I haven't used in in about 18 months... It works (for me).
[13:52:02] <FloppyDisk525> What is autoleveling?
[13:52:24] <FloppyDisk525> You can change your coordinate system via G codes in a few different ways or do tool offset
[13:55:32] <nikre> probing z height at multiple points on the pcb and adjusting the gcode so the spindle doesnt dive or stay high due to surface imperfections
[13:56:56] <FloppyDisk525> I'm gonna say probably, but don't know. You might try googling at the forum at linuxcnc.org??
[13:57:03] <SpeedEvil> nikre: vacuum clamping?
[13:57:19] <SpeedEvil> because if you're not, the PCB may be warped and change shape as it's milled
[13:57:56] <nikre> i dont have SpeedEvil, just a diy wolfstrap frame
[14:20:50] <gregcnc> nikre maybe this
https://github.com/hase-berlin/pcbGcodeZprobing
[14:32:08] <FinboySlick> With single-form thread mills, what determines the min/max thread diameter you can do? (Besides the fact that the tool must fit in the hole on ID threads)
[14:33:29] <cradek> I don't think there's any limit on diameter
[14:34:03] <cradek> of course you run out of cutter if you make the pitch too big, and it may not be pointy enough if you make the pitch too small
[14:34:17] <CaptHindsight> http://www.harveytool.com/secure/Content/Documents/SF_71000.pdf
[14:41:01] <CaptHindsight> FinboySlick:
http://www.sandvik.coromant.com/sitecollectiondocuments/downloads/global/technical%20guides/en-us/c-2920-031.pdf 28MB
[14:42:04] <FinboySlick> CaptHindsight: That first one seems to answer pretty much all my questions.
[14:42:35] <CaptHindsight> the 2nd has more info and lots of illustrations
[14:50:58] <gregcnc> the long necked thread mills chip teeth if you look at them funny
[14:52:27] <FinboySlick> I'll be doing plastic so I'm more likely to break the whole tool than a single tooth.
[14:55:54] <gregcnc> there are some smaller kyocera at a fair price on Ebay
[14:56:34] <gregcnc> I got some from this place last time
http://stores.ebay.com/onlinecarbide?_trksid=p2047675.l2563
[15:01:43] <gregcnc> Harvey are sharp at the tip, the onlinecarbide have a radius and don't chip so easily in steel
[15:03:39] <gregcnc> truck in a box?

[15:11:45] <Deejay> re
[15:35:12] <gregcnc> are the flexible snake indicator mag bases any good? I didn't realize the name brands cost so much.
[15:50:05] <CaptHindsight> I need one for aluminum
[16:44:49] <nikre> i used to connect gnd to en- cw- clk- but this manual says connect +5v to en+ cw+ clk+.

[16:45:32] <nikre> which is the better way?
[16:55:44] <Deejay> gn8
[17:26:40] <MacGalempsy> hello
[17:44:50] <gregcnc> when you're used to manual turning pay attention to direction when you start the spindle for the first time on a slant bed/back tool lathe
[17:50:12] <gregcnc> cutting with the back of the tool doesn't work well, not surprisingly
[17:51:34] <MacGalempsy> well, yesterday I went to the recyclers and thought I got exactly what I wanted, but it was 3/8" plate instead of 1/4"
[17:51:43] <MacGalempsy> beefy time
[17:52:41] <gregcnc> time to recalibrate the fingers
[18:03:57] <SpeedEvil> Or take two nice finishing passes
[18:18:28] <MacGalempsy> well, mostly panels needed to be at least 10"x22 1/2". mounting some electrical stuff on it
[19:03:01] <MacGalempsy> so the machine shop that is having a closing auction had a few good things
[19:03:14] <MacGalempsy> I think the benchtop edm are going to go cheap
[19:03:33] <MacGalempsy> maybe even only $50
[19:03:56] <SpeedEvil> :)
[19:04:08] <SpeedEvil> good luck
[19:04:24] <Valen> wire or sinker?
[19:04:31] <MacGalempsy> sinkers
[19:04:44] <MacGalempsy> they had a half dozen different units
[19:04:53] <MacGalempsy> the best part is everything was working
[19:05:06] <MacGalempsy> i think there were some mitsubishi wire edm in there
[19:05:48] <MacGalempsy> hoping some of those magnetic sine plates go cheap
[19:06:30] <MacGalempsy> at least 3 bridgeports, and some pretty big hurcos
[19:07:06] <MacGalempsy> the cool place was the plastic company that had like 35+ large injection machines
[19:08:15] <MacGalempsy> wow. an edm with a 31 tool changer
[19:08:53] <SpeedEvil> Geez
[19:39:46] <Crom> hmmm looks like I need to install ubuntu on a laptop... so I can have a debian for linuxcnc and a ubuntu for cad
[19:41:31] <Crom> oh shoot... that means this IBM will be the cad machine... BBIAB switching laptops
[20:11:03] <LeelooMinai> what exactly is a draw bar? Is it the thing that screws into the back of a collet?
[20:12:29] <zeeshan|2> yea
[20:12:35] <zeeshan|2> and pulls it closed
[20:13:03] <LeelooMinai> So how does it engage? Just rotates until it catches the thread?
[20:13:29] <zeeshan|2> you hold the collet up with your hand
[20:13:31] <zeeshan|2> and screw it in
[20:14:10] <LeelooMinai> Hmm, on youtube I saw it being done automatically I think.
[20:18:54] <gregcnc> if it has a tool changer the tool holder has a pull stud. the draw bar has a mechanism which automatically engages it
[20:19:40] <LeelooMinai> So it would not use a normal theraded holder?
[20:22:26] <gregcnc> if you see drawbars added to G0704 or bridgeport it will be threaded,

[20:33:36] <tiwake> hey, what is that gear called in the mill that drives the carousel around?
[20:33:50] <tiwake> in CNC mills
[20:34:02] <tiwake> all the CNC mills I've seen anyway, with a carousel
[20:34:07] <gregcnc> geneva cam
[20:34:36] <tiwake> gregcnc: thanks :D
[20:35:25] <LeelooMinai> Or a geneva gear I think
[20:35:36] <LeelooMinai> Or drive
[20:35:46] <LeelooMinai> Right, geneva drive
[20:36:06] <gregcnc> geneva mechanism even
[20:36:31] <LeelooMinai> Looks like a nazi cross + dowell pin...
[20:36:32] <tiwake> its such a sexy mechanism
[20:38:23] <LeelooMinai> I watched some video on youtube where I guy filmed a lot of wooden weird machines and it was there I think, among others.
[20:39:39] <LeelooMinai> lol:

[20:40:10] <LeelooMinai> Someone had a lot of free time...
[20:42:11] <tiwake> https://en.wikipedia.org/wiki/Curta
[20:42:37] <LeelooMinai> Coffee grinder calculator
[21:23:03] <Crom> LeelooMinai, I've seen that in person.. It's 35 miles from me at the Craftsmanship museum in Carlsbad, CA
[21:23:16] <Crom> the do nothing
[21:24:06] <Crom> I want to take a laptop and my 7mm camera and look inside it
[21:30:47] <gregcnc> I like the smoking machine
http://kristoffermyskja.com/work.php#work-display
[21:32:18] <tiwake> what is that?
[21:33:44] <tiwake> oh, had to scroll down further
[21:34:56] <tiwake> lol thats funny
[21:36:33] <LeelooMinai> The coolants they use in videos with CNCs - are they recycled/filtered back in some way?
[21:38:28] <gregcnc> you just keep using it
[21:39:22] <LeelooMinai> I know it's not corrosive, but is it, I don't know, save if touched, ingested, whatever?
[21:39:38] <gregcnc> you have to maintain it, water/oil ratio and make sure it doesn't spoil with bacteria
[21:40:07] <LeelooMinai> It has water in it?
[21:40:10] <gregcnc> some people get reactions to certain types from contact
[21:40:46] <gregcnc> some machines use neat oil, most you see where it's white are >90% water
[21:41:01] <LeelooMinai> Hmm, and this does not corrode steel parts?
[21:41:14] <tiwake> it does.
[21:41:29] <LeelooMinai> Sounds great:p
[21:41:32] <gregcnc> machines running neat oil look much nicer after 20 years
[21:42:13] <tiwake> neat oil?
[21:42:54] <gregcnc> like neat whiskey, you don't put ice or cola in your whiskey do you
[21:43:05] <tiwake> I do... lol
[21:43:12] <gregcnc> lol
[21:43:28] <tiwake> actually, I should pull my bottle out... forgot I had an unopened thing of honey whiskey
[21:43:42] <LeelooMinai> I don't drink, but saw in movies people ordering "whiskey on the rocks", so...
[21:43:48] <tiwake> cause I have a pansy tong
[21:44:10] <gregcnc> most do, but straight is what I like.... neat oil is just oil
[21:44:24] <tiwake> oh hmm
[21:44:33] <gregcnc> screw machines typically run straight oil
[21:44:41] <tiwake> not water soluble oil, just some other kind of oil?
[21:45:06] <gregcnc> there are so many to choose
[21:45:40] <tiwake> it does seem a lot better for the machine, just the places I worked at didnt use it... donno why
[21:45:52] <gregcnc> water is cheap
[21:45:56] <tiwake> well sure
[21:46:21] <tiwake> well
