[00:00:07] <PetefromTn> It is quite a view they say you can see three or four states from that point or something like that.
[00:05:35] <PetefromTn> Come to think of it maybe it is the fifth or sixth LOL
[00:10:26] <PetefromTn> Aah it does not seem to let you walk up the path to the look rock. That sucks. I gotta hit the sack talk tomorrow folks. Peace
[01:13:46] <Valen> eric_unterhausen: try google earth, i *think* it can do that
[01:22:44] <s1dev> does anyone have any suggestions for cheap milling vises in the 3-4" capacity range?
[01:23:17] <s1dev> doesn't matter if its swiveling base or not
[01:59:52] <archivist> s1dev, trawl ebay I managed to get a used one for £5 (not chinese)
[02:00:15] <s1dev> thanks I'll do that
[02:01:08] <archivist> it is a slightly odd one as it has a quick clamp setup for production work
[02:01:57] <s1dev> and do you know anyone who's modified a tailstock to fit a different lathe?
[02:02:02] <archivist> I also got a couple at a local factory close down for work
[02:03:03] <archivist> a good tail stock comes apart in the middle to slide sideways, just make a new base
[02:03:35] <s1dev> like an aluminum spacer?
[02:26:13] <Deejay> moin
[02:39:24] <Jentrep> hey guys :)
[02:39:34] <Jentrep> What is nml_intf ??
[02:41:58] <Jymmm> elaborate and provide context
[02:42:41] <Jentrep> it is a directory name in the linuxcnc source base
[02:42:57] <Jentrep> it contains files like emc.h and emcpos.h
[02:43:10] <Jentrep> emc being the old name for linuxcnc i guess
[02:43:23] <Jentrep> idk anything about linuxcnc :P
[02:43:30] <Jentrep> I am just studying the source :P
[02:45:47] <Jentrep> what would pose math be?
[02:45:53] <Jentrep> there is a file named posemath.h
[02:45:55] <Jentrep> Is that position?
[02:45:58] <Jentrep> What is the e?
[02:46:27] <Deejay> lol
[02:46:54] <Deejay> why has your neighbours car the colour it has... ;)
[02:47:12] <Deejay> why did someone name that directory/file like that...
[02:48:16] <Jentrep> >_>
[02:48:42] <Jentrep> not amused
[02:48:55] <Jymmm> Jentrep: Seriously, you need to get a fucking clue.
[02:49:02] <Jentrep> what?
[02:49:09] <Jymmm> Jentrep: You have no idea what somethg is, yet you want to study it?
[02:49:19] <Jentrep> Yep
[02:49:22] <Jentrep> What is the e?
[02:49:33] <Jymmm> Jentrep: You nquire about smething speicifc, but dont evne bother to fucking look at it?
[02:49:42] <Jentrep> Do you know English?
[02:49:49] <Jymmm> Jentrep: READ THE FUCKING FILE YOU DAMN LAZY BASTARD!
[02:49:55] <Jentrep> Maybe that is why you can't tell me what the e stands for
[02:50:01] <Deejay> calm down, gentlemen ;)
[02:50:04] <Jentrep> Yep, you're retarded
[02:50:05] <Jymmm> Jentrep: It give a full and complete desrbiotns
[02:50:25] <Jentrep> Learn how to talk first then maybe I can understand WTF you are trying to say.
[02:50:49] <Jentrep> >_>
[02:51:22] -!- Jentrep was kicked from #linuxcnc by Jymmm!~jymmm@unaffiliated/jymmm [Jentrep]
[02:52:46] <Jymmm> I have never ever seen better documentation for a header file than that has: https://github.com/sittner/linuxcnc/blob/master/src/libnml/posemath/posemath.h
[02:53:49] <Deejay> oh yes, indeed
[02:53:51] <s1dev> must be illiterate
[02:54:08] <Jymmm> FUCKING people are getting so fucking lazy these days.
[02:54:50] <Jymmm> I about slapped the shit out of my uncle because he said he was too lazy to watch a youtube video on how to do something.... WTF!!!
[02:55:42] <Valen> I don't like watching youtube howtos
[02:55:43] <Jymmm> s1dev: No, ignorance and illiteracy I can fully accept. That was sheer laziness
[02:55:44] <Valen> too slow
[03:00:07] <s1dev> I was wondering whether there was an XKCD comic for this... close enough: http://xkcd.com/293/
[03:01:03] <Jymmm> s1dev++++++++
[03:01:13] <Jymmm> close enough =)
[03:02:16] <Jymmm> s1dev: he was aksing why somethng was named a certain way, but didn't even bother to read the file?
[03:03:01] <Loetmichel> s1dev: there is a xkcd for EVERYTING!
[03:03:31] <Jymmm> Why not 49 shades of grey, or 50 shades or purple, or 101 flavors of red
[03:03:54] <Deejay> :)
[03:04:00] <Jymmm> WHO THE FUCK CARES! Just read the damn book already!
[03:04:19] <Jymmm> (if you are so inclined)
[03:05:28] <Jymmm> Forest, trees, and me without a sniper rifle.
[03:05:57] <Jymmm> I do what I can with a sling shot
[03:06:38] <Jymmm> For the record, yes it IS my time of the month!
[03:06:50] <Valen> its always your time of the month
[03:07:04] <Jymmm> Valen: You think so?
[03:07:10] <Valen> yup
[03:07:25] <Jymmm> Valen: elaborate
[03:07:49] <Valen> I'm not seeing a difference between you today, and any other
[03:08:26] <Jymmm> in what way? being enraged oer stupidity?
[03:08:30] <Jymmm> over*
[03:10:12] <Jymmm> Valen: I honestly want to know.
[03:10:15] <Valen> little from both ;->
[03:10:31] <Jymmm> both?
[03:11:03] <Valen> enraged stupidity ;->
[03:11:47] <Jymmm> I have 100% patients for ignorance, ZERO tolerance for stupidity.
[03:12:54] <Jymmm> I can not accept how someone is entitled to convey their total laziness upon others.
[03:13:38] <gonzo_> (Sillyness is a state of mind. Stupidity is a way of life.)
[03:14:52] <Jymmm> He's studying the source code, but has no idea what linuxcnc is. He's reading the depository filenames, but yet goes on about the NAME of a file without bothering to click on it for a more authorative answer?
[03:15:04] <Jymmm> gonzo_: ...and not enough ammo.
[03:15:29] <gonzo_> even less in the UK
[03:15:51] <gonzo_> ammo that is. We still have our share of stupidity
[03:16:02] <Jymmm> gonzo_: Not for long if DHS keep buyin it all up here in the States.
[03:16:50] <Jymmm> Valen: Feel free to call me on my shit in the future btw.
[03:17:27] <Valen> i generally do
[03:18:34] <Jymmm> Valen: Eh, not really. You dont really comment on such thing excpet in passing.
[03:19:09] <Valen> I am Australian, if somebody is being a dick and i can ignore them thats what I'll do ;->
[03:19:34] <Jymmm> Valen: That's called passive-agressive =)
[03:20:05] <Jymmm> Valen: One step above stupidity, but not by much ;)
[03:22:38] <Valen> http://en.wikipedia.org/wiki/Passive-aggressive_behavior nope
[03:23:11] <Valen> if people don't know what they are talking about i probably shouldn't listen to them ;-P
[03:23:42] <Jymmm> Valen: Oh that... that's just not giving a shit =)
[03:23:58] <Valen> <- A\ustralian
[03:24:20] <Jymmm> Valen: If you aren't giving a shit, doesthat mean you would be full of shit?
[03:24:51] <Valen> I give a shit when its important to me, however i don't give a shit about you ;->
[03:25:06] <Jymmm> Fair enough.
[03:25:14] <Valen> its part of "she'llberightmate"
[03:25:28] <Jymmm> huh?
[03:25:37] <Valen> she'll be right mate
[03:25:41] <Jymmm> lol
[03:26:05] <Jymmm> is that like "no worries" sorta thing?
[03:26:10] <Valen> yup
[03:26:14] <Jymmm> gotcha
[03:26:33] <Jymmm> but the dont give a shit version?
[03:27:28] <Jymmm> That would be "rats ass" here... As In "we dont give a rats ass what you think"
[03:45:29] <Tom_itx> e is a vowel. that's why it's there.
[03:45:44] * Tom_itx buys Jymmm a vowel
[03:46:24] <Jymmm> Tom_itx: Can I regift it for a shorgun instead?
[03:46:39] <Jymmm> shotgun*
[03:48:13] <Tom_itx> will it be used for business or pleasure?
[03:49:03] <Jymmm> I would gain pleasure in taking care of business.
[03:49:55] <Jymmm> But, in reality, on an as needed basis.
[04:43:58] <pekkis> Hi
[04:45:44] <pekkis> could anyone help me update emc2 2.3.0 to later versio
[05:13:11] <archivist_herron> probably if you ask more precise questions
[05:13:51] <archivist_herron> http://linuxcnc.org/docs/html/common/Updating_EMC.html
[05:14:19] * archivist_herron points jthornton at the above url :)
[05:17:03] <jthornton> this early in the morning?
[05:19:23] <pekkis> I trying this but it get fault
[05:20:15] <pekkis> examble: http://security.ubuntu.com/ubuntu/dists/hardy-security/main/binary-i386/Packages.gz nouto ei onnistunut 404 Not Found [IP: 91.189.92.190 80]
[05:21:18] <jthornton> that doesn't look like it has anything to do with LinuxCNC
[05:24:19] <pekkis> hmm. but nothing is change after that
[05:24:58] <jthornton> after what?
[05:26:09] <pekkis> I try update my old version linuxcnc 2.3
[05:26:57] <jthornton> did you follow the instructions in the link that archivist provided?
[05:27:34] <pekkis> yes I try
[05:28:04] <jthornton> what version of Ubuntu are you using now?
[05:28:13] <pekkis> but sorry I have to go now to work, I'll back some other day. Thanks
[05:28:26] <pekkis> 8.04 Hardy Heron
[05:29:06] <archivist_herron> ubuntu repos are no valid for old distros
[05:29:20] <jthornton> ok, should be easy to update EMC to LinuxCNC
[05:30:15] <archivist_herron> I hate ubuntu deleting old urls
[05:30:30] <pekkis> I have also Ubuntu 10.04 but emc 2.5 is not start
[05:31:53] <jthornton> is your computer very old?
[05:32:31] <pekkis> yes IBM R50e
[05:32:39] <pekkis> but sorry I go now
[05:32:43] <pekkis> thanks for all
[06:27:49] <Loetmichel> *gnah*... why do i have to have black clothing when milling some kgs of aluminium on the cnc router? *silver sparkling everywhere ;-(
[06:32:50] * Loetmichel looks like this at the moment, only in silver, not white plastic... -> http://www.cyrom.org/palbum/main.php?g2_itemId=5077
[06:35:43] <MarkusBec> Loetmichel: auto translation ? :D
[06:38:39] <Loetmichel> MarkusBec: gray matter translation ;-
[06:38:41] <Loetmichel> )
[06:38:49] <MarkusBec> :)
[07:06:03] <R2E4> mornin!!
[07:11:56] <R2E4> moving along with my VM-40 retrofit. http://www.youtube.com/watch?v=znQ5X5r495w&feature=youtu.be
[07:17:47] <skunkworks> yay.
[07:17:52] <skunkworks> Yay!
[07:21:27] <Valen> Loetmichel: rofl
[07:22:24] <Valen> better than me after polishing Al https://fbcdn-sphotos-f-a.akamaihd.net/hphotos-ak-prn1/t1/539166_4441374309659_1255185278_n.jpg
[07:22:58] <eric_unterhausen> were you polishing it with your face?
[07:23:13] <Valen> heh, no, just polishing a lot of it
[07:23:23] <skunkworks> isn't that how everyone does it?
[07:23:38] <skunkworks> you need a face mask!
[07:23:57] <Valen> hey i was wearing glasses see?
[07:24:08] <eric_unterhausen> get a face shield
[07:24:22] <skunkworks> I see that ;)
[07:24:24] <eric_unterhausen> w/ tearaways
[07:24:29] <Valen> eh, cbf lol
[07:24:29] <R2E4> I guess in Japan they consider 100vac as low voltage. alot of the switching is 100vac, some 12vdc and some 24vdc.
[07:24:32] <Valen> it washes off ok
[07:25:30] <eric_unterhausen> Valen: buffing wheel?
[07:25:37] <Valen> yeah
[07:25:59] <eric_unterhausen> so your shoes looked a lot worse
[07:26:19] <Valen> you know I dont know lol
[07:26:24] <Valen> probably
[07:30:16] <Loetmichel> valen thats like me cutting ferrite plates to size... -> http://www.cyrom.org/palbum/main.php?g2_itemId=13525 ;-)
[07:30:40] <Valen> I dunno.... i think i came out blacker ;-P
[07:30:55] <Valen> how do you cut ferrite without it doing bad things btw?
[07:31:11] <Tom_itx> carefully
[07:31:24] <Loetmichel> with a diamond wheel
[07:31:29] <Loetmichel> .. and careful ;-)
[07:31:49] <Tom_itx> i cut some with a cutoff wheel but it took a while
[07:32:13] <Loetmichel> diamond cutoff disks rule for that
[07:32:26] * Tom_itx feels Loetmichel came out entirely too clean
[07:32:29] <Loetmichel> like you see in the photo ;-)
[07:32:38] <Loetmichel> some experience isnt that bad, either ;-)
[07:33:16] <Loetmichel> and a stady hand if doing it free hand like me ;-9
[07:33:26] <Loetmichel> steady
[07:33:27] <Valen> don't do it on a lathe
[07:33:32] <Valen> stuff is harder than carbide
[07:33:45] <Valen> well let me rephrase, don't try using carbide lathe bits to cut it
[07:33:49] <Valen> ;->
[07:33:57] <Loetmichel> i know
[07:34:21] <Loetmichel> but you CAn use a glass cutter if only straight cuts
[07:34:29] <Loetmichel> it behaves like glass
[07:34:39] <Loetmichel> scratch it, break
[07:34:42] <Loetmichel> works every time
[07:36:17] <Loetmichel> even thoug i used a dust mask i sneezed black three days though ;-)
[07:36:53] <skunkworks> that isn't a good enough dust mask...
[07:37:27] <Loetmichel> i notced ;-)
[07:37:27] <Valen> oooh nasty
[07:37:30] <Loetmichel> noticed
[07:37:36] <skunkworks> if you read the warning on those masks - they are pretty much just good for - well nothing...
[07:38:14] <skunkworks> big wood chips?
[07:38:41] <eric_unterhausen> they work reasonably well for fiberglass
[07:38:55] <eric_unterhausen> although I have better masks I should use
[07:46:35] <skunkworks> could you tell if you where sneezing out fiber glass? ;)
[07:50:26] <Loetmichel> skunkworks: i can
[07:50:36] <skunkworks> heh
[07:50:47] <Loetmichel> i have milled gfk and cfk on a daily bais some years ago
[07:51:02] <Loetmichel> on cfk days you WILL sneeze black, even with dust mask
[07:51:18] <Loetmichel> and on gfk days slightly whiteisch
[07:51:20] <Loetmichel> -s
[07:54:18] <skunkworks> yum
[08:13:36] <archivist_herron> ex boss after a few hours on the buff http://www.collection.archivist.info/showresult.php?prog=1&srcprog=searchv13.php&srcdata=title&Type=PD&Accn_no=4176&subject=13455
[08:18:03] <skunkworks> he looks evil...
[08:18:47] <Valen> archivist_herron: lol
[08:19:28] <Valen> Loetmichel: those masks wont work *at all* with the face fuzz
[08:19:39] <archivist_herron> I was sat working and this apparition appeared
[08:20:21] <archivist_herron> was polishing brass castings
[08:24:01] <Valen> polished brass, is there anything sexier in terms of a metal?
[08:54:34] <jmasseo> my first attempt at casting brass was a failure :/
[08:54:40] <jmasseo> need to try again
[08:54:40] <jmasseo> also
[08:54:47] <jmasseo> casting grain instead of random shop scrap might help. :)
[08:55:14] <jmasseo> do my melt in the forge instead of with a torch next time as well
[09:47:57] <jdh> http://tinyurl.com/m7srbol Any idea where to find one of these?
[09:48:06] <jdh> (time delay relay)
[09:48:27] <skunkworks> ouch
[09:49:42] <R2E4> Image is not loading for me.
[09:50:22] <Jymmm> jdh: Grainger, McMaster, Ebay
[09:50:49] <Jymmm> jdh: better to toss on imagebin btw
[09:52:29] <jdh> http://imagebin.org/289721
[09:53:12] <jdh> I've looked on the usual places. Syrelec is now Crouzet but can't find any cross references
[09:57:17] <jdh> what is the dashed line between pins 2 and 6?
[09:58:02] <Jymmm> jdh: what isthe relay for?
[09:58:15] <jdh> residential elevator
[09:58:24] <Jymmm> jdh: purpose?
[09:58:26] <jdh> but, no clue what part. Friends quit working
[09:58:44] <jdh> I suggested that the fried relay is a symptom, not the real problem.
[09:59:31] <Jymmm> Yeah, I'm suspecting whatever burned it out.... overcurrent?
[10:00:16] <jdh> that's my guess. He hasn't opened it to see what fried.
[10:04:37] <Jymmm> jdh: http://www.ebay.com/itm/NCC-TMM-0999M-461-LOT-OF-2-/171224131000?pt=LH_DefaultDomain_0&hash=item27ddc0e5b8
[10:05:45] <Jymmm> jdh: it CAN be programmed for DELAY ON BREAK, just need to find the 24V version.
[10:06:11] <jdh> wont fit the base
[10:06:27] <Jymmm> jdh: it cmes with it's own base
[10:08:03] <Jymmm> Most of the bases are universal, some ight have to be rewired. Her'es a 24 version http://www.ebay.com/itm/NNC-SOLID-STATE-TIMER-TMM-0999M-462-/221359273911?pt=BI_Control_Systems_PLCs&hash=item338a0a77b7
[10:08:44] <Jymmm> Sorry, 24VDC. The 24VAC is -467 suffix
[10:11:58] <Jymmm> jdh: 24VAC http://www.ebay.com/itm/NCC-Timer-Time-Delay-Relay-TMM-0999M-467-/350054680659?pt=LH_DefaultDomain_0&hash=item5180e28853
[10:12:30] <Jymmm> jdh: Just giving options if he cna't find an alternative is all
[10:12:58] <jdh> I'm sure the elevator company would fix it
[10:13:12] <jdh> I don't think random modifications would be a good idea though.
[10:13:26] <Jymmm> And they should if for nothing else liability issues.
[10:14:58] <Jymmm> Not random mod, just an alternative replacement.
[10:15:16] <Jymmm> Not like the intent is to change the functionality
[10:16:03] <Jymmm> relays, contactors, controls go obsolete.
[10:16:53] <ReadError> who in here was doing the pick-and-place ?
[10:17:00] <ReadError> I remember someone mentioned it a week back or so
[10:21:08] <Deejay> re
[10:26:33] <R2E4> I am ongoing with my retrofit removing the old control and replacing with LinuxCnc
[10:27:05] <R2E4> I have these contactors turning on 3 ph motors.
[10:28:04] <R2E4> 100vac to control them going into the plc, along with that there is a pair of 18guage connected to the contactor with a dial marked arc and three settings.
[10:28:34] <R2E4> I cannot find reference to this in the schematics. Anyone have an idea of what this would be?
[10:28:47] <R2E4> fuji SRC 3931-00
[10:29:56] <ReadError> will linux CNC do the CV?
[10:31:12] <R2E4> at time 26 seconds, you can see them on top. there is three of them. http://www.youtube.com/watch?v=znQ5X5r495w&feature=youtu.be
[10:31:26] <R2E4> I didnt conenct them and the motors power up no problem.
[10:32:05] <R2E4> They are foor flood coolant, chip spiral conveyor and hydraulic pump.
[10:42:08] <skunkworks> ReadError, CV?
[10:43:20] <ReadError> computer vision
[10:43:30] <skunkworks> that would be cool..
[10:43:56] <skunkworks> CaptHindsight was working on something similar
[10:45:58] <archivist> ReadError, use opencv and some "interfacing"
[10:48:41] <ReadError> oh maybe it was CaptHindsight doing the pick-and-place
[10:58:28] <CaptHindsight> I'm using vision for automated alignment and inspection
[10:59:03] <ReadError> CaptHindsight: have any links or anything regarding your setup? or if someone else has done something similar before?
[11:02:26] <skunkworks> CaptHindsight, the matsuura homes..
[11:03:17] <CaptHindsight> skunkworks: nice
[11:03:47] <CaptHindsight> ReadError: I wish someone else had done it all before
[11:04:15] <ReadError> keep me posted, very interested in how it works out for ya
[11:05:06] <CaptHindsight> ReadError: I'm under NDA for some of this work. I'll post the stuff I can and the others a later this year. I have to pick through it.
[11:05:18] <FinboySlick> If I need plastic glued stronger than new, what would you guys recommend? I guess it depends on the type of plastic but I'll take what you guys can throw at me.
[11:05:36] <CaptHindsight> FinboySlick: what plastic?
[11:05:59] <FinboySlick> CaptHindsight: I'm not entirely sure. It's molded, that'S for sure. And the type that becomes white when bent.
[11:07:34] <ReadError> CaptHindsight: all the other open source controller apps seemed to be half finished/beta still
[11:07:43] <ReadError> couldnt find anything that actually had a following yet
[11:07:47] <CaptHindsight> FinboySlick: some epoxies are stronger than most thermoplastics but you might have to prep your plastic first before bonding
[11:08:06] <CaptHindsight> ReadError: yeah, what I found so we had to make it
[11:10:33] <CaptHindsight> ReadError: we have to inspect the surface of a non-planar object, look for defects and then move a tool into that area and perform repairs
[11:11:30] <CaptHindsight> the machine gets loaded manually by an operator but the inspection and repair is all automated
[11:12:48] <ReadError> ohhh
[11:12:54] <ReadError> I thought it was a pick-n-place
[11:12:56] <CaptHindsight> we integrated a zoom microscope so it can scan and then zoom in for the repair
[11:13:10] <CaptHindsight> it could easily be adapted for pick-n-place
[11:13:23] <CaptHindsight> even on non-planar surfaces
[11:13:39] <FinboySlick> CaptHindsight: Prep as in buff the surfaces clean?
[11:14:57] <CaptHindsight> FinboySlick: solvent clean and scuff, depending on the plastic you might be able to solvent weld it, but that would only be as strong not more than originally
[11:16:24] <CaptHindsight> ReadError: the makerspace in Chicago made some open pick-n-place PS1
[11:16:31] <CaptHindsight> check their blog
[11:16:39] <CaptHindsight> they used Linuxcnc
[11:16:52] <FinboySlick> CaptHindsight: Thanks. I'll look into it. Do most moldings have stamped numbers which might give me hints as to the type of plastic?
[11:17:26] <CaptHindsight> http://en.wikipedia.org/wiki/Resin_identification_code
[11:17:57] <FinboySlick> CaptHindsight: Perfect. I'll look it up. Thanks again!

[11:20:18] <ReadError> CaptHindsight well none of the projects I found have actually gotten anywhere
[11:20:27] <ReadError> they start then die off, never see anymore updates
[11:21:49] <CaptHindsight> tjt posted some links recently
[11:23:25] <CaptHindsight> ReadError: my project is 5 axis + 3 more for a laser, the zoom motor doesn't really count
[11:26:46] <CaptHindsight> https://github.com/openpnp/openpnp/wiki/Developers-Guide Right now OpenPnP is not really ready for end user use. To get it going requires a pretty good understanding of programming and Java.

[11:37:17] <CaptHindsight> after we get a few other things sorted out with RTAI and ARM, I'll start a pick-n-place section on the EMC wiki
[11:39:18] <CaptHindsight> ReadError: is this dead? http://code.google.com/p/my-pnp/ software for DIY-pick&place machine, compatible with LinuxCNC
[11:43:00] <CaptHindsight> heh, empty repo
[11:44:31] <diginet0> does linuxcnc have support for controlling linear motors?
[11:44:45] <CaptHindsight> https://github.com/openpnp/grbl
[11:44:52] <CaptHindsight> diginet0: yes
[11:45:03] <CaptHindsight> they are servos
[11:45:55] <diginet0> CaptHindsight: what if the linear motors in question aren't servos?
[11:46:31] <CaptHindsight> diginet0: lets clarify, are yours a magnet track with a forcer coil?
[11:47:04] <diginet0> CaptHindsight: well I don't have one yet, but yeah that's what I plan to get, along with a linear encoder
[11:47:35] <diginet0> CaptHindsight: network is about to go down so I might disconnect any moment now
[11:48:13] <CaptHindsight> linear servo motor is just that, a linear positioner could have a linear motor or lead/ballscrew, belt, pneumatic or hydraulic cylinder
[11:48:46] <diginet0> CaptHindsight: but does LinuxCNC take care of the servo algorithms?
[11:48:53] <CaptHindsight> yes
[11:49:27] <CaptHindsight> I use linear motors all the time with Linuxcnc btw
[11:49:42] <diginet0> does linear servo-ing differ from rotary? I've read some papers that have all of these really elaborate control loops, much more than say PID
[11:50:42] <CaptHindsight> coil motor and encoder feedback
[11:51:19] <diginet0> I mean as in the algorithms used?
[11:51:32] <CaptHindsight> just watch your fingers and have bumpers for stops
[11:51:49] <CaptHindsight> PID works well
[11:51:50] <diginet0> CaptHindsight: what about braking?
[11:52:01] <CaptHindsight> PID
[11:52:06] <diginet0> ah
[11:52:11] <diginet0> also, does that mean that LinuxCNC could use DC motors with encoders?
[11:52:39] <CaptHindsight> braking using the forcer or a secondary brake?
[11:53:17] <diginet0> well what I mean is that if you stop applying power to leadscrew it just stops right there, I don't think that happens with a linear motor
[11:53:26] <CaptHindsight> yes you can use DC motors with an encoder
[11:53:57] <diginet0> do people do that often? how does it compare in terms of performance to using real servos?
[11:54:13] <CaptHindsight> if you care how it stops then you don't stop them by just cutting the power
[11:54:22] <diginet0> (sorry for my probably dumb questions, and thanks so thaks so much)
[11:54:30] <CaptHindsight> it depends on the motor design
[11:54:35] <skunkworks> diginet0, it applies opposite electrical force.. same as with a dc servo motor
[11:54:42] <CaptHindsight> BLDC vs brushed DC
[11:54:47] <diginet0> skunkworks, CaptHindsight ahhhh okay
[11:55:02] <skunkworks> there are people that have used linear motors with linuxcnc
[11:55:02] <diginet0> sorry I have relatively little direct experience with this stuff
[11:55:32] <CaptHindsight> no problem, just read up on the different motors
[11:55:35] <diginet0> I'm trying to homebrew a linear motor, well half-way, you can buy the tracks for next to nothing, I want to try my hand at make the coils
[11:56:01] <diginet0> CaptHindsight: it's irritating because so much linear motor stuff is mired in extremely vague and obscure proprietary stuff
[11:56:06] <CaptHindsight> heh, you can buy both on ebay for cheap, but if it's just for fun
[11:56:35] <CaptHindsight> lots of missed-matched stuff there
[11:56:37] <diginet0> CaptHindsight: define cheap though, I define cheap as in sub-$100
[11:56:47] <CaptHindsight> yeah <$100
[11:56:52] <skunkworks> http://www.youtube.com/watch?v=A-wmHVPLJ6Q
[11:56:58] <diginet0> really? complete assemblies?
[11:57:30] <diginet0> the other tricky thing is motor controllers, designs abounds for BLDC controllers, but not so much for linear motors
[11:58:27] <diginet0> the ironless designs are nice because you don't need to worry about the laminated "stators"
[11:58:53] <CaptHindsight> you could make a coil like a BLDC for a magnet track
[11:59:35] <diginet0> oh I know, you just makes the coils and encase them in some sort of epoxy, and hope the thing that doesn't catch on fire ;)
[11:59:49] <CaptHindsight> the real science in making the motors is the materials
[11:59:54] <diginet0> indeed
[12:00:05] <diginet0> I've seen some thermally conductive epoxies I might try out for it
[12:00:09] <diginet0> CaptHindsight: what kind of repeatability/accuracy do you get?
[12:00:50] <diginet0> in your linear motor setup I mean
[12:02:15] <CaptHindsight> we can get submicron in controlled environments, but setups with 0.5m travel are easily few microns with 2G accell/decell
[12:02:33] <diginet0> wow, that's impressive
[12:02:48] <diginet0> by controlled environments, do you mean like climate control?
[12:02:59] <CaptHindsight> yes, in a box
[12:03:10] <diginet0> ahh, cool
[12:03:28] <diginet0> can LCNC work with LVDTs for the linear "encoders?"
[12:05:07] <CaptHindsight> http://imagebin.org/287237 this one is <5um
[12:05:24] <skunkworks> if the lvdt ouputs something linuxcnc can read (quadature for one..)
[12:05:50] <diginet0> CaptHindsight: that's awesome, what do you use it for?
[12:05:57] <zeeshan> CaptHindsight: you should start a photobucket account
[12:05:58] <diginet0> skunkworks: ah okay
[12:06:04] <zeeshan> so i can surf through your pictures :p
[12:06:08] <skunkworks> if lvdt you mean resolver - mesa and pico has hardware that will read them directly
[12:06:47] <jdh> usually analog output
[12:08:58] <IchGuckLive> hio all B)
[12:09:05] <diginet0> skunkworks: maybe that's it, I just meant something to measure the linear position
[12:09:16] <IchGuckLive> Atlanta 1cm snow state of emergency !
[12:09:17] <CaptHindsight> diginet0: you don't have to worry about epoxies unless you plan on tweaking to get the most out of it, you can just use a spray or dip clear
[12:09:48] <CaptHindsight> IchGuckLive: yeah, any snow down south and it's a disaster
[12:09:50] <diginet0> CaptHindsight: ahh, I just meant encase them in something so that their position is stable
[12:09:51] <jdh> IchGuckLive: more that that... people have been stuck on the interstate since yesterday
[12:10:09] <CaptHindsight> IchGuckLive: like +42 C in Germany
[12:10:10] <diginet0> CaptHindsight: we get the tiniest bit of sleet here in Houston and the whole city shuts down
[12:10:13] <diginet0> it's insane
[12:10:15] <IchGuckLive> jdh: most school kids
[12:10:34] <IchGuckLive> CaptHindsight: why did there the govener not interfer
[12:10:37] <diginet0> on a somewhat unrelated noted, I see 5-axis CNCs a lot, but not so often 6-axis ones, is there a reason for that?
[12:11:07] <IchGuckLive> diginet0: 6th axis are only for spare partrs
[12:11:19] <jdh> we got an inch or so of ice then snow on top. Most everything is shut down.
[12:11:20] <IchGuckLive> 5axis can do the most
[12:12:19] <diginet0> IchGuckLive: ahh, so the basically there's diminishing returns?
[12:12:27] <IchGuckLive> diginet0: the 6th axis offen used for tool correction only
[12:12:55] <diginet0> I see.
[12:13:21] <diginet0> yeah, my project is a 3D printer, so obviously I don't need rotational axes, but I'd like to build a multiaxis CNC one day
[12:13:21] <IchGuckLive> also the Double Z gives you a wonderfull drilling in all angels
[12:13:35] <diginet0> IchGuckLive: what is double Z?
[12:13:36] <IchGuckLive> diginet0: why homebuild
[12:13:44] <IchGuckLive> 3D
[12:13:52] <diginet0> IchGuckLive: which? the 3D printer or the CNC?
[12:14:01] <IchGuckLive> there are cheep with all goods inside
[12:14:12] <IchGuckLive> 3d print
[12:14:22] <diginet0> mostly because I'm disastisfied with most of the offerings, and controlling with LinuxCNC would be vastly superior to the others
[12:14:25] <IchGuckLive> and the parts to order are so cheep now
[12:14:31] <diginet0> also to learn/experiment
[12:14:48] <diginet0> it seems silly to me to calculate tool paths using an 8-bit micro
[12:14:54] <IchGuckLive> the 3D printers in modern time do nort se codes
[12:15:03] <IchGuckLive> stl and print
[12:15:14] <CaptHindsight> I love Enco, they ship so fast my orders get here before they send me the tracking info
[12:15:15] <IchGuckLive> its that easy no G-code for users
[12:15:34] <diginet0> yeah but like most firmwares can't even do true curves
[12:16:19] <diginet0> plus, I want to do a few things different, like a heated build chamber (not just platform), so why even bother because it'd be easier to just do it myself
[12:16:35] <diginet0> if I'm going to change everything about it, why even bother buying one?
[12:17:50] <IchGuckLive> agree
[12:17:56] <diginet0> IMO, the way reprap does it is incredibly arcane
[12:18:02] <IchGuckLive> you got a look on freesculpter ex1
[12:18:31] <IchGuckLive> it got all you talking about
[12:18:36] <diginet0> IchGuckLive: sadly, I don't speak German :(
[12:18:46] <IchGuckLive> diginet0: where are you from
[12:18:51] <IchGuckLive> continent
[12:19:02] <diginet0> IchGuckLive: N. America, Texas specifically
[12:19:14] <diginet0> I have a vague goal to learn German one day though :P
[12:19:50] <IchGuckLive> Obama anounced today 1.5 Bilion Dollars for our town from the US military budget
[12:20:05] <diginet0> IchGuckLive: which town is that?
[12:20:24] <IchGuckLive> Ramstein Kaiiserslautern Weilerbach
[12:20:41] <diginet0> ah, is there a military base there or something?
[12:20:53] <jdh> he must not know you can't buy votes there.
[12:21:31] <diginet0> jdh: it does bother me how much Obama panders to the EU
[12:22:22] <diginet0> I do love though, what Merkel said about the NSA thing, "Like the Stasi, just less competent"
[12:23:01] <mozmck> buy votes? all you need is a backdoor to the voting machines!
[12:23:23] <diginet0> mozmck: those things are hilariously/disturbingly unsecure
[12:23:58] <IchGuckLive> diginet0: here are 60.000 us soldiers around
[12:24:11] <diginet0> IchGuckLive: ahhh, fun
[12:24:19] <IchGuckLive> and every woundet world wide of us military is shipped in
[12:24:33] <mozmck> it's amazing how often I see some new article about how there's a bug in how the voting machines count votes.
[12:24:40] <IchGuckLive> or folwn in by C17 24/7
[12:24:47] <diginet0> mozmck: isn't it though?
[12:24:51] <CaptHindsight> what makes anyone think that the counting of the votes here is accurate?
[12:25:09] <CaptHindsight> there is no way to check
[12:25:12] <diginet0> IchGuckLive: another thing I'm experimenting with is an inductively heated extruder
[12:25:18] <diginet0> CaptHindsight: where is "here" for you?
[12:25:23] <CaptHindsight> US
[12:25:42] <diginet0> ah, that's what mozmck and I were referring to as well, I think
[12:25:44] <diginet0> at least I was
[12:26:06] <CaptHindsight> yeah
[12:26:34] <Jymmm> Does anyone recall that commercial about Farmers that was narrated by someone with a very distinctive voice?
[12:27:02] <diginet0> Jymmm: as in Farmers insurance?
[12:27:06] <diginet0> no, sorry
[12:27:34] <IchGuckLive> Jymmm: the counts of the menoits ? since what time they gone vote
[12:27:49] <Jymmm> Ah... http://www.youtube.com/watch?v=AMpZ0TGjbWE
[12:29:34] <diginet0> CaptHindsight: do you have any pictures of parts you've made with your 5-axis? just out of curiosity
[12:31:41] <skunkworks> really - you have never heard of paul harvey?
[12:35:23] <Jymmm> skunkworks: 1) no, 2) I just could recall the commercial.
[12:35:31] <Jymmm> couldn't*
[12:36:51] <diginet0> CaptHindsight: http://goo.gl/bTKUiR I guess you're right
[12:52:45] <IchGuckLive> Loetmichel: wann schläfst du eigentlich du bist ja fast immer hier
[12:54:35] <Jymmm> IchGuckLive: If you do, you clean it up!
[12:56:36] <Loetmichel> IchGuckLive: i dont ;-)
[12:56:44] <Deejay> hi IchGuckLive
[12:56:53] <Deejay> Loetmichel is a zombie ;)
[12:57:13] <Deejay> some kind of living channel inventory ;)
[12:57:54] <Loetmichel> IchGuckLive: for real: as the PC is running 24/7 the irc client is logged in also 24/7
[12:58:39] <Loetmichel> i DO sleep from time to time. and go to work (where i have a tunnel back home and vnc to chat on this machine here ;-)
[12:59:03] <IchGuckLive> O.O B)
[13:02:59] <FinboySlick> I think the bastards put the resin code on the inside of the molding. And as this is a battery i'm not too keen on taking it apart to look.
[13:32:40] <pcw_home> hmm with just make, linuxcnc hangs trying make clean,make
[13:39:17] <PetefromTn> Got a question guys..
[13:39:37] <PetefromTn> I am trying to run a part I designed and setup in CamBam for the first time.
[13:40:01] <PetefromTn> I ran a single operation to test both in air and then in the material and everything went fine.
[13:40:25] <PetefromTn> Now I am trying to run the following operations and the tool needed is tool 23
[13:40:47] <jmasseo> did you configure your tool table in cambam?>
[13:40:51] <PetefromTn> I do not have tool 23 in the tool table and when I try to load the new program it says so and I click okay and it does not load the program
[13:41:04] <PetefromTn> No not using tool offsets in cambam.
[13:41:14] <PetefromTn> Using tool table in LinuxCNC on the machine.
[13:41:51] <PetefromTn> I did not however setup this tool because I was planning to just set the zero on the work surface just to test and probably run in air too before I cut anything.
[13:42:07] <PetefromTn> Not sure of the code but I did run it in simulation and it looks good.
[13:42:44] <PetefromTn> Problem is LinuxCNC won't let me open the tool table to setup the new tool now and If I restart LinuxCNC I may lose position possibly.
[13:43:09] <pcw_home> skunkworks: any of the svst configs should have pwm/stepgens/encoders
[13:44:45] <skunkworks> pcw_home, thanks
[13:47:29] <PetefromTn> I ran the first operation which is just a bolt circle drill pattern and everything looks real good so far. Any ideas how to load this tool into linuxCNC without having to restart? I am sure it is something stupid I am missing.
[13:47:31] <CaptHindsight> Amazon is starting slip
[13:48:28] <CaptHindsight> has anyone noticed their countdowns being very inaccurate? "order in the next hour and have it tomorrow"
[13:48:58] <CaptHindsight> then in 30 minutes it says "order in the next 5 hours" and it still takes 2-3 days until you get it
[13:49:43] <Tom_itx> PetefromTn it should let you edit the tool table
[13:49:57] <Tom_itx> change the tool number in the program if you can't then reload it
[13:50:44] <PetefromTn> I seem to recall someone telling me the the tool table will only load before you do something but I already ran a program here and now It does not seem to want to let me into the tool table.
[13:51:07] <PetefromTn> Too bad you can't click the tool number down below there in axis and change it LOL.
[13:51:40] <Tom_itx> if you don't wanna rerun code, delete it and save the parts then run the parts
[13:51:47] <Tom_itx> until you figure out the tool table
[13:52:04] <Tom_itx> i set my table up with tools that match my cad cam tool list
[13:53:38] <PetefromTn> I set up my tools to match my cad cam tool list as well but I only use the length offsets on the machine. Everything in the cad cam is zero offset that way.
[13:53:49] <Tom_itx> ie: save each tool path as a program
[13:54:02] <Tom_itx> i don't do it that way
[13:54:27] <PetefromTn> I do not want to rerrun the code I already machined how do I delete the program so I can load the new one without restarting linuxCNC??
[13:54:31] <Tom_itx> i set my tools off a 123 block in a safe zone
[13:54:41] <Tom_itx> gedit
[13:54:42] <PetefromTn> so do I...
[13:54:48] <Tom_itx> then reload the code in lcnc
[13:55:05] <Tom_itx> did it stop at a tool change?
[13:55:15] <PetefromTn> it stopped after the program was finished.
[13:55:27] <Tom_itx> what's left to run then?
[13:55:44] <PetefromTn> Basically this part consists of several machining ops and I only posted code for one initiallly to test with.
[13:56:01] <Tom_itx> so do like i said above
[13:56:06] <Tom_itx> save each tool as a file
[13:56:10] <PetefromTn> Now I want to run the rest of the code in another posting not including the first machining op to finish the part.
[13:56:16] <Tom_itx> until you figure out the tool table
[13:56:39] <PetefromTn> maybe I am not being clear. I understand the tool table and length offsets.
[13:56:58] <PetefromTn> What I cannot seem to do is open the tool table to load a new tool so I can load this program for it.
[13:57:25] <Tom_itx> gedit will edit it
[13:57:41] <PetefromTn> Is there a way to open the tool table without closing linuxCNC axis?
[13:57:42] <Tom_itx> then reload the tool table
[13:57:52] <Tom_itx> from the menu
[13:57:53] <PetefromTn> Okay lemme try that. thanks
[13:58:21] <Tom_itx> it should save any offsets you had set though
[14:01:00] <PetefromTn> It should and this is a closed loop servo system with encoder feedback so I SHOULD be alright but this is a prototype and I don't have much extra material to screw around with right now LOL
[14:01:21] <ler_hydra> does anyone have a rough rule-of-thumb of the amount of tracking error that you'd normally expect for a servo/encoder system? On the order of 10-20 counts when starting/stopping acceleration (IE. high jerk), and more like 5-10 during mild constant-acceleration moves?
[14:08:08] <CaptHindsight> I just got some 8mm drill rods in. I can't believe that repraps actually use them for linear bearings. Way too much flex for anything over few of travel
[14:08:22] <CaptHindsight> few in or cm
[14:08:42] <Tom_itx> they don't have to worry about good alignment that way
[14:08:48] <CaptHindsight> heh
[14:09:19] <jmasseo> are they hard or soft rods?
[14:09:56] <jmasseo> drill rod is usually a tool steel of some sort.
[14:09:58] <Tom_itx> drill rod comes water or oil hardened generally
[14:10:10] <Tom_itx> with a price difference
[14:10:24] <CaptHindsight> http://www.use-enco.com/CGI/INSRIT?PMAKA=505-0240
[14:10:31] <CaptHindsight> these are oil
[14:10:33] <jmasseo> yeah, o1, w1, and a2.
[14:10:40] <jmasseo> at my local supply shop
[14:10:51] <jmasseo> but they are usually half hard cold rolled, right?
[14:11:12] <Tom_itx> yeah they're not that hard to start with
[14:11:19] <jmasseo> right
[14:11:22] <jmasseo> they don't ship them annealed
[14:11:29] <jmasseo> so it's the cold roll work hardness
[14:11:39] <jmasseo> oil hardening.
[14:11:52] <jmasseo> good luck heat treating it. :)
[14:12:16] <Tom_itx> not that bad
[14:12:17] <jmasseo> 36" rod is hard to HT w/o warping.
[14:12:25] <jmasseo> the long kiln is hard to find.
[14:12:33] <jmasseo> unless you've got a salt rig
[14:13:13] <archivist> do it vertically and drop into the bath
[14:13:21] <jmasseo> yeah that's the best way to do it
[14:13:25] <jmasseo> if you've got a salt bath setup.
[14:13:40] <jmasseo> that's the dream for home HT'ing. :)
[14:13:54] <jmasseo> me and a buddy are still trying to finish our 30" blade kiln.
[14:15:02] <jmasseo> of course now that we're looking at other blade patterns, 30" is looking a bit short. :)
[14:15:32] <CaptHindsight> chrome-moly worked well for pushrods
[14:16:48] <CaptHindsight> did anyone see that video of the reprap with software error correction without feedback?
[14:18:00] <jmasseo> 4140?

[14:19:17] <CaptHindsight> http://3dprintingindustry.com/2014/01/27/robots-drones-use-brushed-dc-motors-3d-printers/
[14:20:00] <PetefromTn> Well crap I tried to use the Gedit to load the tool number and it would not stick until I reloaded linuxCNC axis.
[14:20:30] <CaptHindsight> "Its position feedback control system consists of thousands of software code lines written into the RAPPY PUMP DC motor control board. " :)
[14:20:42] <CaptHindsight> this should obsolete servos
[14:21:00] <PetefromTn> Then when I opened it up the offsets were not right because it was not homed out yet. I got lost in it and whatever I did I lost the zero location now.
[14:21:46] <PetefromTn> Gonna have to try to picup the zero location again now. It really sucks that you gotta remember to open the tool table if you intend to make any adjustments to it before you do anything.
[14:22:18] <PetefromTn> I dunno what causes it to lock it down but if I do not open the tool table upon startup of LinuxCNC it will not open and I cannot make any changes.
[14:34:56] <PetefromTn> Can anyone tell me why you cannot open the tool table at any point in time?
[14:35:04] <Tom_itx> lemme try
[14:37:08] <PetefromTn> I mean what if you break a tool and need to load a new one that is slightly different? If you already started doing something in LinuxCNC it won't let you open it. At least mine won't.
[14:38:23] <Tom_itx> during a program run?
[14:38:29] <Tom_itx> or while it's sitting idle?
[14:38:34] <PetefromTn> yeah.
[14:38:36] <Tom_itx> i can open mine while it's sitting
[14:38:36] <cradek> possibly? http://sourceforge.net/p/emc/bugs/347/
[14:38:39] <PetefromTn> either..
[14:39:52] <PetefromTn> So it is a bug then? That patch will fix it... How do I install that patch?
[14:42:43] <PetefromTn> Okay downloaded the patch, I am not a programmer type how do I use it?
[14:44:38] <PetefromTn> Once I home the machine out on the VMC if I forget to open the tool table I am locked out regardless of how long it has been sitting.
[14:45:54] <Tom_itx> mmm, mine works as expected
[14:49:33] <Tom_itx> looks like you may have to recompile it
[14:49:40] <Tom_itx> could be wrong...
[14:51:09] <Pekkis> hi! Could any one help me with Ubuntu 10.04 and LinuxCNC 2.5.3 this is not start

[14:57:17] <Tom_itx> try in -devel
[14:57:19] <Tom_itx> maybe
[15:01:21] <PetefromTn> sorry I was looking at the file and trying to see if there was a not attached.
[15:01:29] <PetefromTn> How do I get to Devel?
[15:02:03] <Tom_itx> /j #linuxcnc-devel
[15:02:10] <CaptHindsight> #linuxcnc-devel
[15:02:13] <Tom_itx> i asked them... waiting for a reply
[15:02:23] <PetefromTn> THank you Tom.
[15:11:35] <Tom_itx> PetefromTn, http://www.linuxcnc.org/linuxcnc/emc2/index.php/italian/forum/20-g-code/24387-tool-offset-patch?start=12
[15:11:39] <Tom_itx> you may be in for a treat
[15:12:00] <Tom_itx> different patch, same idea
[15:13:27] <PetefromTn> Jeez man I guess you need to be a programmer then.
[15:18:08] <PetefromTn> Well I guess I will just scrap this piece and start over.
[15:18:22] <Tom_itx> aww, don't give up so easy
[15:18:30] <PetefromTn> I think the code is good but I wanted to be more careful
[15:18:44] <Tom_itx> what exactly do you need to do?
[15:18:46] <PetefromTn> Oh I am not giving up but I NEED to make this prototype
[15:18:49] <Tom_itx> you ran some code already...
[15:19:02] <PetefromTn> yeah I ran the drilling cycle first op and it went great.
[15:19:10] <Tom_itx> now what?
[15:19:29] <ler_hydra> Ill try asking again ( ;) ) does anyone have a rough rule-of-thumb of the amount of tracking error that you'd normally expect for a servo/encoder system? Maybe something around the order of 10-20 counts when starting/stopping acceleration (IE. high jerk), and more like 5-10 during mild constant-acceleration moves?
[15:20:52] <PetefromTn> I am unfortunately without a good edge finder holer right now so I started this program using a pointer to the middle of a piece of stock and I doubt I can get that zero picked up again by eyeball LOL
[15:21:13] <PetefromTn> I have a nice electronic edge finder here but I need a holder for it.
[15:21:56] <PetefromTn> I was just gonna rely on the fact that the machine remembers the offsets and its homing is precise and machine the whole part at one time but in stages.
[15:22:06] <Tom_itx> it's supposed to
[15:22:24] <PetefromTn> Now I screwed up trying to restart linuxCNC and as soon as I homed it out I lost the offset somehow.
[15:22:37] <PetefromTn> Probably my stupidity but it is gone now.
[15:23:15] <PetefromTn> I could try to put my pointer toolholder I occasionally use to locate stuff on round stock and try to carefully pick up the offset again but that is pretty iffy.
[15:23:31] <PetefromTn> I seriously doubt I could get within a couple thousandths.
[15:24:08] <PetefromTn> The hole pattern is in a thin wall that is in a cicle so if it is off even a little it will both not line up and look funky.
[15:24:15] <Tom_itx> may as well finish out with this chunk so you don't scrap more than one
[15:24:26] <PetefromTn> That's why I said I will just scrap it.
[15:24:56] <PetefromTn> I may just try to pick up the offset but it would only be just to try it. I need to get this machined here
[15:25:23] <PetefromTn> Got a bunch of new tooling for this project here and also do not want to break anything LOL.
[15:26:14] <PetefromTn> I think I will try to pick up the center again. I suppose I could rerun the drilling op and go real slow to see if the drill lines up after I pickup the center again.
[15:27:09] <PetefromTn> Kinda pisses me off that I will probably lose this part because I can't open the damn tool table to edit it. It was mentioned that you can open the tool table from the command line how would you do that?
[16:01:10] <CHNCguy> JT-Shop, you in buddy?
[16:01:24] <CHNCguy> What was the link for your collet closer o-rings?
[16:26:14] <JT-Shop> I got them from McMaster Carr
[16:26:28] <CHNCguy> Just found your post ;)
[16:26:43] <CHNCguy> Did you have any further issues with your collet closer?
[16:26:51] <CHNCguy> Or did those seals work out for ya?
[16:27:15] <JT-Shop> it leaks air like a sieve when open, not so bad when closed
[16:28:22] <CHNCguy> Cool, I just ordered the seals, Mine work without leaking, but they need to be cleaned and I figured new seals would be good while im in there... ;)
[16:29:23] <JT-Shop> if you can figure out why it doesn't leak tell me so i can fix mine
[16:30:28] <rob_h> ooo nasty chnc collet closer, i think hardinge had a thing about air logic and anything else that could work on air in the 80s
[16:30:44] <JT-Shop> air was free in the 80's
[16:31:04] <rob_h> aaah thats what it was
[16:32:00] <rob_h> wish i had time to fit that hydrolic closer i picked up to ours :)
[16:32:18] <rob_h> have u fixed ur spindle yet?
[16:33:19] <MrSunshine> http://www.frets.com/HomeShopTech/hstpages.html alot of shop goodies =)
[16:33:29] <CHNCguy> Sure, which ones did u have? I have 2 different kind, one has a black mechanism on the back, and the other had a silvery type of ring. Check out my post here too see what I have. http://www.cnczone.com/forums/newreply.php?do=postreply&t=200960
[16:33:34] <CHNCguy> Whats wrong with your spindle?

[16:41:38] <Deejay> gn8
[16:44:24] <JT-Shop> me, no I've been busy with work to try the 15hp RPC
[16:45:43] <CHNCguy> Ive built rpcs before
[16:45:49] <CHNCguy> what info u need ;0)?
[16:47:09] <CHNCguy> I have a 20hp RPC and runs the spindles good
[16:47:37] <JT-Shop> I can build them in my sleep but my Siemens 611 drive on my BP 308 has tremendous inrush so the drive trips out
[16:47:48] <JT-Shop> I need to find a 20hp motor
[16:48:10] <CHNCguy> I have 2 40hps if u want one?
[16:48:14] <JT-Shop> I have a heavy duty 15hp motor that I need to try
[16:48:23] <JT-Shop> 40 is a bit much I think
[16:48:41] <CHNCguy> Well did u put an a/c reactor on the line side?
[16:49:19] <zeeshan|2> why put an ac reactor
[16:49:20] <zeeshan|2> ;D
[16:49:38] <CHNCguy> Are u trying to start the RPC with the drive directly connected? Or are u switching the drive with a relay?
[16:49:45] <JT-Shop> how many caps do you have on your 20hp rpc?
[16:50:25] <JT-Shop> no, I start the rpc then throw the switch on the 308 then take a nap then turn the drives on
[16:50:48] <JT-Shop> I can get 3k without tripping out now with my 10hp rpc
[16:50:55] <CHNCguy> I have 6 running caps, and 4 starting caps
[16:50:59] <JT-Shop> well 3k with rapids and such
[16:51:45] <CHNCguy> zeeshan, an ac reactor just helps the electronics down the line for inrush current and voltage fluctuations
[16:51:53] <JT-Shop> I have mostly 60mf caps and IIRC 4 on AC 2 on BC and 2 on AB with C the generated phase
[16:53:14] <rob_h> JT has a nice 50amp PM servo/Spindle motor to spin up 0 - 6k pritty fast.. so quite nice inrush demand there plus the axis moving around
[16:53:32] <CHNCguy> Ill have to look at the specs, I use L2 for the 3rd phase and bridge L1 to L2 to start
[16:54:06] <PetefromTn> Okay guy ran the program again and ran into another little problem. Wanted your advice.
[16:54:30] <CHNCguy> Well my rule is, if spindle is 7.5hp, and drives are 2kw or more than a 20hp rpc is needed to max out
[16:55:00] <PetefromTn> After the drilling operation the machine just brings the tool up to the safe Z level and stops and gives an M6 for the next tool. LinuxCNC asks you to change to that tool and hit okay.
[16:55:03] <CHNCguy> You can always add another idler motor
[16:55:17] <CHNCguy> I did this to power my 40hp mazak
[16:55:51] <CHNCguy> I had it run off a 40hp rpc and added a 20hp idler that I started after the 40hp, and then switched the mazak on
[16:55:55] <PetefromTn> Well this drill chuck is rather long and it stopped right above the workpiece so I was unable to remove it so I can change tools and LinuxCNC has no jog while paused feature so I could not raise the head to change tools.
[16:55:58] <rob_h> 11kw motor so 15hp
[16:56:54] <CHNCguy> I never like to go more than half the motors rated hp for draw, ive had issues in the past with phase fluctuations.
[16:57:29] <rob_h> yea i think the siemends drive can be picky on phases as it does regen back to line also
[16:57:44] <PetefromTn> I need to modify my post processor in camBam so I can have the machine go up to a toolchange height enough to get the current tool out and insert the next tool. What would you input there I assume machine coordinates Z height of appropriate position?
[16:57:55] <rob_h> PetefromTn, sorry cant help i dont use the next tool function sorry.. must suck no Atc
[16:58:20] <PetefromTn> Actually I have an ATC it is just not finished being retrofitted into the control.
[16:58:23] <rob_h> G91 G28 Z0 does that not send it back to the G28 for u, which is normaly set at the machine Z top/home
[16:58:32] <rob_h> manual tells you how to set the G28
[16:58:36] <rob_h> g28.1 i think?
[16:59:57] <PetefromTn> Okay so I can input that into the PP for toolchange after the M6 command and I should be good once I setup the machine G28?
[17:00:06] <JT-Shop> I need to up my wire size and try the 15hp to see what I get
[17:00:30] <rob_h> before the tool call
[17:00:55] <JT-Shop> CHNCguy, what do you mean by this?
[17:00:55] <JT-Shop> <CHNCguy> I never like to go more than half the motors rated hp for draw, ive had issues in the past with phase fluctuations.
[17:00:56] <rob_h> so end of drill, G80 G00 Z to clear.. then G91 G28 Z0 , then Txx M6
[17:01:00] <PetefromTn> This of course would be temporary until I can get the toolchanger finished. I need to make some parts here and it will be a little while before I can get it working.
[17:01:50] <PetefromTn> No I am trying to setup the Post Processor to bring the machine to the top of Z after each toolchange.
[17:02:13] <rob_h> normaly nice to have G28 on Z to tool change hight anyway. so just put them 3 words in, Z moves up stops spindle also.. and there ready for the T command
[17:02:43] <PetefromTn> I think you are right tho If I input the G91 G28 then the next line is M6
[17:04:08] <PetefromTn> The code CamBam is putting out looks good so far but ya gotta get the tool out of the work to change the cat40 tooling here LOL
[17:04:14] <rob_h> G91 G28 on its own will send all Axis to G28 point
[17:04:33] <CHNCguy> JT-shop, I mean that our CHNC's have a max spindle rating of 7.5kw which equates to about 7.5hp, This does not include all of the peripheral electronics running off the RPC. Each Drive probably sucks 1kw when driven hard. What about your relays? Spindle drive it self, etc. etc.
[17:04:38] <PetefromTn> Does the G91 G28 also turn off the spindle automatically?
[17:04:50] <rob_h> no
[17:05:02] <rob_h> just put a m05 on the end ;)
[17:05:07] <CHNCguy> When your motor gets pushed over half its HP, it starts to suck on the fake phase and then throw all ur phases out of sync
[17:05:11] <rob_h> then turn it off while it goes up for u
[17:05:29] <rob_h> chncguy this is a diff machine not a CHNC
[17:05:39] <CHNCguy> Ohh... My bad ;)
[17:05:47] <CHNCguy> But still
[17:05:50] <PetefromTn> interesting the code I just posted does not have any M5 in it and the spinde stopped for the toolchange anyways...
[17:05:51] <rob_h> so 11kw 15hp spindle motor... plus axis
[17:06:11] <rob_h> i think the linuxcnc tool change thingie prob does it, would be bad other wise ;)
[17:06:26] <CHNCguy> So what is being asked again? LOL
[17:06:28] <rob_h> i dont know what it does and does not do sorry
[17:06:48] <rob_h> jt has a machine, 11kw spindle motor... prob 1kw each servo 3axis..

[17:07:07] <rob_h> just wondering what size rcp ud think be best i think
[17:07:07] <PetefromTn> G83 X-0.44128 Y0.60735 Z-0.625 Q0.1 R0.25
[17:07:10] <PetefromTn> G80
[17:07:11] <CHNCguy> But if you are running a RPC you have to have 2x the idler motor to run effectively and nicely...So for a 15hp motor you would want a 40hp
[17:07:12] <PetefromTn> m9
[17:07:16] <PetefromTn> This is the code for the first op and I watched it stop the spindle after this for the toolchange.
[17:07:20] <rob_h> lol, PetefromTn try pastbin ;)
[17:07:29] <CHNCguy> LOL
[17:07:31] <PetefromTn> oh okay sorry..
[17:07:44] <PetefromTn> I am not that great with this IRC stuff yet LOL
[17:08:01] <CHNCguy> If you have a 15hp spindle motor. Assuming All of you electronics are on 120v different line than your RPC you could do ok with a 30hp
[17:08:04] <JT-Shop> CHNCguy, yea my CHNC runs perfect
[17:08:27] <PetefromTn> The next line is the T23 m6 command.
[17:08:31] <CHNCguy> Powering a 15hp spindle with a 15hp RPC aint gonna work :(
[17:08:33] <JT-Shop> this is a BP Discovery 308 VMC
[17:08:58] <JT-Shop> the 308 is a small VMC with 7.5 hp spindle
[17:09:00] <CHNCguy> The issue is that the spindle is a 15hp spindle, but the draw will cripple your 3rd phase
[17:09:10] <CHNCguy> I thought rob said 15hp spindle
[17:09:31] <JT-Shop> no, I think he said 15kw or something like that
[17:09:44] <CHNCguy> well I remember this issue with my Haas Vf-2
[17:10:03] <CHNCguy> The drive has an AUTO kill function if any of the phases become misaligned or out of sync
[17:10:07] <JT-Shop> according to Siemens the 611 is a "high performance" drive and needs lots of inrush current
[17:10:25] <CHNCguy> that siemens probably has the same function
[17:10:37] <CHNCguy> what leg is your HIGH leg on?
[17:10:46] <CHNCguy> of your primary transformer to your vmc?
[17:11:03] <rob_h> did u havea question with the above code PetefromTn
[17:11:04] <JT-Shop> C
[17:11:07] <JT-Shop> W
[17:11:35] <rob_h> why does it G83 every line?
[17:12:25] <PetefromTn> Not sure it is modal in LinuxCNC no?
[17:12:35] <MrSunshine> anyone know a source of brush strips or bristle strips or whatever it should be called that is good for dust boots? =)
[17:12:45] <rob_h> when u enter the G83, its current untill a G80
[17:12:59] <PetefromTn> This is in the cambam linuxCNC post processor.
[17:12:59] <MrSunshine> found the ones for power sweapers or whatever but it costs 5x the price of the strips in shipping :/
[17:13:05] <rob_h> so just need to issue next move in this case
[17:13:12] <CHNCguy> C W?
[17:13:19] <CaptHindsight> paging tjtr33, was wondering what is a good small EDM for aluminum parts say < 6"x6"x6"
[17:13:35] <rob_h> no G43 ether? or was that some where else
[17:13:48] <CHNCguy> If you have a multimeter you should see 120/G 120/G 240/G (240 is your high leg). G= Ground
[17:14:14] <CHNCguy> You should have only 1 high leg and that should goto your middle tap on your transformer.
[17:15:44] <CHNCguy> Either way, sounds like a great project, got any pics JT?
[17:16:21] <JT-Shop> I don't think I've tried putting the generated leg on the middle tap, what's the reason for that?
[17:16:44] <JT-Shop> http://www.gnipsel.com/shop/machine-shop.xhtml
[17:17:27] <PetefromTn> Not really sure man.
[17:17:41] <CHNCguy> Well I don't really know...but I could not get my Haas powered properly, so I called Haas and they said that when using an RPC the high leg must always be on the middle leg. Electrician rule. Because lots of the sensing and peripheral electronics allow voltage fluctuations on the middle leg of transformers, but not on the others...
[17:17:59] <rob_h> PetefromTn, http://pastebin.com/tHF4jazD this is modded up for u
[17:18:04] <rob_h> how id write it hope it helps,
[17:18:05] <JT-Shop> thanks for the tip
[17:18:05] <PetefromTn> I just need to know where to put the G91 G28 in the post so it will go to some height I designate. Right now it goes to the clearance plain.
[17:18:23] <rob_h> i put in a G54 also so uses work offset G54 , uses H02 from tool table so need to measure the tool
[17:18:37] <rob_h> at the end it sends Z to G28.. then asks for next tool
[17:19:33] <rob_h> what spindle inertor is in the hass CHNCguy
[17:19:45] <rob_h> dont they use yaskawa abit?
[17:19:46] <CHNCguy> I had a Yaskawa
[17:19:54] <PetefromTn> Okay I think I got it..
[17:20:31] <CHNCguy> JT, try to get your high leg on your center tap meaning L2 and let me know ;)
[17:22:20] <JT-Shop> ok
[17:22:24] <rob_h> PetefromTn, btw, on line 5 might want to make Z bigger value to clear any parts i dont know if it flat or what
[17:22:46] <rob_h> waits for the US to be plunged into darknes by JT ;)
[17:23:07] <CHNCguy> When you run a rpc that fake leg that u generate is higher than the other 2 when measured across eachother
[17:23:53] <PetefromTn> OK
[17:23:55] <CHNCguy> This is what u should see with a DMM/Multimeter L1-L2 260+ L1-L3 240- L2-L3 260+
[17:31:20] <rob_h> sleep time here, ni all
[17:31:26] <CHNCguy> night!'
[17:34:28] <JT-Shop> no change in symptoms, still trips out at 4k
[17:34:37] <JT-Shop> I really think I need more hp on my rpc
[17:35:07] <CHNCguy> yup now u know its ur rpc
[17:35:14] <CHNCguy> just add an idler
[17:35:19] <CHNCguy> like a 5hp
[17:35:47] <CHNCguy> Hook it up with a switch and switch it on after ur 15p turns on fully
[17:35:55] <CHNCguy> run it parallel
[17:36:06] <CHNCguy> not series
[17:36:10] <andypugh> Ot go solid-state....
[17:36:30] <CHNCguy> 20hp solid state = 2k+
[17:36:43] <andypugh> Only if you _buy_ it
[17:37:04] <CHNCguy> lol
[17:37:14] <CHNCguy> got schematics to _make_it?
[17:37:27] <JT-Shop> right now I'm running on a 10hp
[17:37:33] <andypugh> I was thinking more along the lines of stealing :-)
[17:37:39] <CHNCguy> lol
[17:38:46] <andypugh> Though, actually, I reckon a fmesa card, 3-phase PWm and some big power transistors and caps might do the trick.
[17:38:48] <JT-Shop> right now with the work rob_h and I did the other day it runs 10 times better than it had in a while
[17:39:06] * JT-Shop waits for the schematic
[17:40:41] <JT-Shop> wow propane is $4 a gallon more than double
[17:42:04] <CHNCguy> dang, gasifier here I come
[17:42:52] <CHNCguy> Do you have a spare 3 phase motor laying around?
[17:43:33] <JT-Shop> a few
[17:44:38] <Jymmm> If you connect three 3h motors together, do they become one phase with the universe?
[17:44:46] <Jymmm> 3ph*
[17:45:22] <CHNCguy> wire the 3 leads to the same leads on your rpc box and see what happens, you will have a slower start time, but when they are up and running then try ur mill
[17:46:00] <JT-Shop> I have several 3ph machines on the same buss, a 7.5hp lathe, a surface grinder
[17:46:15] <JT-Shop> the CHNC is on it's own rpc
[17:46:22] <CHNCguy> lol what u could do.......
[17:46:33] <CHNCguy> run ur lathe on the slowest setting
[17:46:41] <CHNCguy> and then try ur mill also,
[17:46:47] <JT-Shop> I tried running the lathe spindle before with no improvement
[17:46:47] <CHNCguy> but lathe has to be little or no load
[17:47:01] <CHNCguy> with no load?
[17:47:10] <JT-Shop> run the spindle out of gear
[17:47:30] <JT-Shop> it was in gear before spinning the spindle and 4 jaw
[17:48:37] <CHNCguy> run with no load
[17:49:11] <CHNCguy> if it has any load at all if will not help
[17:49:27] <CHNCguy> it
[17:50:47] <CHNCguy> work better?
[17:55:10] <JT-Shop> yes it does help and I hear the lathe motor buzz during spindle spool up
[17:55:21] <JT-Shop> I'm running 4500 on the spindle with rapids
[17:55:39] <JT-Shop> actually I have both the lathe and surface grinder on
[17:56:30] <CHNCguy> Glad that helped, can u max the spindle?
[17:58:08] <CHNCguy> you need a 20hp RPC to be happy, the start caps are no big deal, just get large ones to start the rpc under 1 sec, the running caps help to smooth the 3rd phase I cant remember the rating, I can look tho
[17:58:13] <JT-Shop> not tried yet, program running
[17:58:30] <JT-Shop> any info is helpful
[17:59:01] <CHNCguy> You helped me aton, its only fair that i try to return the favor ;), but you could get a 40 hp and run all ur machines at one if need be
[17:59:32] <CHNCguy> I once*
[17:59:34] <CHNCguy> once*
[18:00:54] <JT-Shop> I usually only run one, and the CHNC has a built in rpc the rest of the fleet is single phase
[18:01:21] <JT-Shop> I need to find a 20hp motor
[18:01:39] <CHNCguy> what hp is ur lathe 3ph motor?
[18:01:46] <JT-Shop> and swap the 8-4 SO for some 6-4 SO
[18:01:54] <JT-Shop> 7.5 I think
[18:02:04] <JT-Shop> been a while since I looked
[18:02:23] <CHNCguy> well 1 large motor is better than 2 small ones, you need to find an induction a/c motor, that what mine are
[18:03:22] <JT-Shop> just started at 5k
[18:03:32] <CHNCguy> 5k?
[18:03:35] <JT-Shop> like a normal ac motor?
[18:03:36] <CHNCguy> ohh
[18:03:39] <CHNCguy> the spindle :)
[18:03:44] <JT-Shop> here goes 5.5k
[18:03:53] <JT-Shop> did 5.5k
[18:03:55] <CHNCguy> try it 5.5k :)
[18:04:14] <CHNCguy> 6k?
[18:04:15] <JT-Shop> it ain't never did that since I had it
[18:04:25] <CHNCguy> sweet! :D
[18:04:50] <JT-Shop> yes, thanks for the help
[18:05:28] <CHNCguy> Whoot Whoot, im glad you know what you need now! Im gonna have tons of questions for you in a week or so as I start to wire up my lathes ;)
[18:06:27] <JT-Shop> I hope I remember the answers
[18:07:15] <CHNCguy> Haha, I can't thank you enough for the help from ur site, where are ya located by the way?
[18:07:22] <CHNCguy> Im near Pensacola FL
[18:08:52] <JT-Shop> I'm in Poplar Bluff MO
[18:09:06] <JT-Shop> I used to live in Pascagoula MS
[18:09:20] <JT-Shop> as well as other places
[18:10:00] <CHNCguy> Is it cold up there? ;)
[18:10:10] <jdh> friend in pensacola said her power went out overnight due to weather
[18:10:41] <CHNCguy> Yup, all the bridges are closed because they froze over LOL
[18:10:43] <JT-Shop> it has been in the single digits at night and 20-30 during the day
[18:12:21] <JT-Shop> 5k, cut a bit, tool change 5.5k, cut a bit, tool change, 6k, cut a while
[18:12:27] <JT-Shop> I'm stoked!
[18:12:45] <JT-Shop> someone wake rob_h up and tell him
[18:12:53] <CHNCguy> HELL YA! ;)
[18:13:32] <CHNCguy> how does ur rpc sound? Strained?
[18:15:34] <JT-Shop> the lathe motor buzzes during high loads for a second
[18:16:01] <JT-Shop> the 308 is running 6k and rapid and feed moves all over the place
[18:16:20] <CHNCguy> well theres your short term fix ;)
[18:17:18] <JT-Shop> I actually have a 20hp but it is 3600 rpm and didn't do well when I tried it
[18:17:28] <Tom_itx> JT-Shop: propane shortage..
[18:18:11] <CHNCguy> mmm you need a very low inertia motor, if you spin it by hand it should spin for a few seconds at least until it stops
[18:18:18] <CHNCguy> inductive motors work best for rpcs
[18:18:37] <CHNCguy> that motor might have bad bearings or not balanced nicely
[18:19:16] <JT-Shop> I guess I don't know the difference what an inductive motor is?
[18:19:40] <CHNCguy> well its the way the motor handles the power and all that
[18:21:35] <JT-Shop> these are the motors http://www.gnipsel.com/images/motors.jpg
[18:21:54] <JT-Shop> the vertical one is the 20hp well motor
[18:21:57] <Tom_itx> JT-Shop what exactly did you change to get the performance boost?
[18:22:03] <Tom_itx> kinda hard to follow...
[18:22:05] <JT-Shop> the heavy duty frame is the 15hp motor
[18:22:48] <JT-Shop> I turned on my lathe with the gearbox in neutral and the surface grinder motor which are all on the same buss
[18:22:51] <CHNCguy> added the lathe 3ph motor as a boost idler
[18:23:07] <Tom_itx> heh cool
[18:23:16] <JT-Shop> yea, way cool!
[18:23:22] <Tom_itx> guess you need a bigger motor on your inverter now?
[18:23:45] <JT-Shop> yea, need to sell some to make room lol
[18:24:01] <Tom_itx> what's the grey one front center?
[18:24:22] <Tom_itx> looks rather hefty
[18:24:37] <JT-Shop> that's the 15hp
[18:24:52] <JT-Shop> the red one is the heavy one
[18:25:54] <CHNCguy> well, i don't know but, did yo wire the leads to the windings the same? The motor may be wound differently and have different poles and all that
[18:27:09] <CaptHindsight> Automation Direct closed down today since I guess they closed Georgia due to bad weather.
[18:27:19] <JT-Shop> the 20hp only has 3 wires
[18:27:44] <Jymmm> JT-Shop: Stop, go, and go real fast?
[18:27:51] <CHNCguy> 3 wires coming out, but there is a main bus below the panel
[18:28:07] <CaptHindsight> wow, what do they consider bad weather in Ga?
[18:28:12] <CHNCguy> there is probably 12-18 different wound coils to the main bus
[18:29:11] <Tom_itx> CaptHindsight no kidding...
[18:29:18] <JT-Shop> there is no box on the 20hp, just 3 wires coming out of the hole
[18:30:09] <JT-Shop> CHNCguy, the 20hp is a hollow shaft well motor
[18:30:20] <JT-Shop> not your typical motor
[18:30:37] <CHNCguy> ya doesnt sound like an inductive motor, does it say inductive on the side?
[18:32:46] <JT-Shop> I think the other wires were not brought out when someone rewound it as I see the high low connections on another tag
[18:33:10] <JT-Shop> the tag is covered with paint and rather hard to read
[18:33:34] <Tom_itx> take a pic of it and look at it on the pc
[18:33:39] <Tom_itx> that helps alot of times
[18:34:05] <JT-Shop> I rather just find a normal TEFC 20hp motor and get rid of that one
[18:34:33] <CHNCguy> I agree get an elevator motor off ebay cheap
[18:34:33] <JT-Shop> CHNCguy, thanks for the help, I'm off the the house now
[18:34:41] <CHNCguy> your welcome, take care ;)
[18:34:48] <JT-Shop> elevator motor?
[18:35:21] <JT-Shop> I can get motors from a local motor repair shop, I just have to call and find one
[18:38:59] <JT-Shop> http://www.ebay.com/itm/20HP-Severe-Duty-Reliance-Electric-Motor-/111264709241?pt=LH_DefaultDomain_0&hash=item19e7e4ba79
[18:39:12] <CHNCguy> Yes usually elevator motors are inductive and make very good rpc IMHo
[18:39:31] <JT-Shop> what is an elevator motor?
[18:39:47] <CHNCguy> A motor used in an elevator ;)
[18:40:21] <JT-Shop> what makes them different?
[18:40:28] <Tom_itx> http://www.ebay.com/itm/Submersible-Hydraulic-Pump-Elevator-Motor-20HP-3Phase-3400RPM-NO-RESERVE-/221360096004?pt=LH_DefaultDomain_0&hash=item338a170304
[18:40:35] <Tom_itx> ?
[18:40:46] <CHNCguy> Nah not that TOM
[18:41:15] <CHNCguy> u need a low rpm, 240 inductive motor, used to run elevators like the ones that go up and down LOL
[18:41:38] <JT-Shop> what is low rpm? 900?
[18:41:42] <CHNCguy> 3k
[18:41:49] <Tom_itx> http://www.ebay.com/itm/US-Motors-30-HP-Dry-Hydraulic-Elevator-Motor-200v-3-DH30P2H-C-/161018070210?pt=LH_DefaultDomain_0&hash=item257d6cc4c2
[18:42:11] <CHNCguy> that would work tom
[18:42:13] <JT-Shop> 3k is not low rpm
[18:42:33] <Tom_itx> buy it now 495
[18:42:36] <CHNCguy> let me go look at mine 1 sec
[18:42:56] * JT-Shop thinks most motors in the 20hp range are all induction motors
[18:43:50] <CHNCguy> ya 1750 is good
[18:44:24] * JT-Shop needs to call it a night
[18:45:43] <CHNCguy> night ttyl
[18:45:51] <Tom_itx> 460v no good?
[18:47:44] <CHNCguy> nah, i wouldnt use it, 200-260 sure
[19:45:10] <CHNCguy> night yall

[21:02:08] <eric_unterhausen> http://www.youtube.com/watch?v=9qt5ui3P9QA&feature=youtu.be
[21:02:26] <Tom_itx> man, cambam really sucks compared to ....
[21:04:34] <eric_unterhausen> there is no camera tricks
[21:08:23] <Tom_itx> is it better with sound?
[21:08:39] <eric_unterhausen> no, cambam still sucks without sound
[21:08:49] <Tom_itx> just checking
[21:08:50] <Tom_itx> thanks
[21:09:28] <Tom_itx> i was gonna try to educate myself a bit but am having second thoughts
[21:09:36] <eric_unterhausen> I have no idea
[21:09:45] <Tom_itx> neat idea with the router...
[21:09:49] <eric_unterhausen> I thought about getting a copy back when he was giving it away
[21:09:51] <uw> cambam does kinda suck
[21:09:55] <uw> but still better than pycam
[21:10:00] <uw> talk about suck
[21:10:02] <eric_unterhausen> how much is it nowadays?
[21:10:03] <Tom_itx> how do you draw a line?
[21:10:14] <Tom_itx> no idea, i'm not about to buy it
[21:10:20] <uw> i dont think i've ever gotten a good tool path ever out of pycam
[21:10:29] <uw> that didnt need srs messing with
[21:10:32] <eric_unterhausen> what happened to heeks?
[21:12:18] <Tom_itx> the guy should have made a round disk with an offcenter hole to use on the guide
[21:12:21] <Tom_itx> depth control
[21:12:27] <Tom_itx> then remove it for the final pass
[21:12:56] <Tom_itx> kinda reminds me of the old bridgeport tracer
[21:13:51] <eric_unterhausen> my boss was making snide remarks about the c-clamp
[21:14:06] <eric_unterhausen> good thing he wasn't there Sunday when I was moving one of the spindles off the lathe
[21:14:15] <Tom_itx> i missed that.. was only halfway watching it
[21:15:01] <Tom_itx> oh you mean the belt tensioner?
[21:15:36] <eric_unterhausen> ya, but mostly I decided not to tell my boss how good c-clamps work to hold an engine hoist onto a pallet jack
[21:15:47] <Tom_itx> vise grips would have been a better choice
[21:16:01] <eric_unterhausen> for me or the motor guy?
[21:16:09] <Tom_itx> lathe video
[21:16:14] <eric_unterhausen> motor guy is using whatever he can get
[21:16:36] <eric_unterhausen> although, go to Harbor freight on the right day and you can get vice grips awfully cheap
[21:17:53] <Tom_itx> damn this is soooo slow
[21:19:18] <PetefromTn> Can someone send me a GOOD linuxCNC program that works so I can compare my new post processed files to it and make sure it includes everything I need.
[21:19:29] <Tom_itx> sure
[21:19:38] <PetefromTn> Thanks man.
[21:19:39] <Tom_itx> i probably have one posted
[21:20:02] <PetefromTn> LinuxCNC does use H callouts for comp right?
[21:20:11] <Tom_itx> yes
[21:21:02] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/cnc_files/
[21:21:06] <Tom_itx> that cube should be ok
[21:21:11] <Tom_itx> i can put more up if you need
[21:21:18] <Tom_itx> those are from my smartcam post
[21:21:41] <Tom_itx> feeds n speeds are way slow
[21:22:22] <Tom_itx> i was trying to figure cambam out so i could tell you where to edit the G28 Z0
[21:23:23] <Tom_itx> i think i would add it in the END CUT area
[21:23:36] <Tom_itx> G91 G28 Z0
[21:24:03] <Tom_itx> i change it on mine and specify a coordinate
[21:24:20] <Tom_itx> i like to move the table out of the way a bit depending on the part
[21:24:30] <Tom_itx> so i generally move Y a bit
[21:25:08] <Tom_itx> this is way too slow for me to work with on this old pc
[21:25:21] <PetefromTn> Okay man thanks. Yeah we got the post looking a lot better and I was able to input the G28 where I want it
[21:25:32] <Tom_itx> was that the right place?
[21:25:59] <PetefromTn> However not sure why but there is no G43 H whatever in the code at all... It may be because I need to setup tool table in camBam or something. Not sure yet. Asking on their forum
[21:26:17] <PetefromTn> So far it is looking good and the software is interesting and capable especially for the price.
[21:26:36] <os1r1s> PetefromTn: Do you need a G43 is there is an M06?
[21:26:51] <PetefromTn> Yeah at every toolchange...
[21:26:55] <Tom_itx> you need to set your tools
[21:27:04] <Tom_itx> before it can add tool info
[21:27:28] <PetefromTn> I did set my tools on the machine and the tools used in the program are setup obviously or the code would not post.
[21:27:31] <Tom_itx> i just can't deal with the slowness
[21:27:49] <PetefromTn> what slowness?
[21:27:57] <Tom_itx> i downloaded it to try
[21:28:15] <os1r1s> I bought it, but I'm not happy with it (cambam)
[21:28:19] <Tom_itx> all my pcs are fairly dated
[21:28:23] <eric_unterhausen> how much is it?
[21:28:36] <Tom_itx> i'll stick to smartcam
[21:28:53] <Tom_itx> even as dated as this copy is, i can do anything i need to do with it
[21:29:23] <os1r1s> Tom_itx: I've found dolphincam to be the most usable reasonably priced one
[21:29:27] <os1r1s> fwiw
[21:29:46] <Tom_itx> i don't need another one, i was just gonna look at cambam for pete
[21:30:28] <Tom_itx> i can do full 3d 3 axis or lathe and that's all i need
[21:30:33] <PetefromTn> I do not know why you would not be happy with it? It does all sorts of cool stuff that most cheap programs cannot do.
[21:30:40] <os1r1s> Tom_itx: cambam is really limited in lathe function
[21:30:48] <os1r1s> Tom_itx: Its pretty much useless for it
[21:31:04] <Tom_itx> i have the basic lathe package for smartcam but it's really all you need
[21:31:06] <PetefromTn> Yeah that is true but I don't use it for lathe I just want the 3d milling from it.
[21:31:29] <PetefromTn> Have not even played with lathe yet.
[21:31:31] <Tom_itx> PetefromTn, it takes 10 sec to update every move i make
[21:31:55] <PetefromTn> not having any problems with speed from it here at all.
[21:32:06] <Tom_itx> you got newer PCs
[21:32:13] <PetefromTn> Of course I am running on a pretty fast windows 8 laptop.
[21:32:56] <PetefromTn> Let me post this code I just made and you can give me your opinions on it so I can figure out how to improve the post if you don't mind.
[21:33:02] <PetefromTn> Where can I post it again?
[21:33:07] <Tom_itx> pastebin
[21:34:17] <PetefromTn> http://pastebin.com/5WkwMg3Q
[21:35:53] <Tom_L> you don't want cutter comp?
[21:36:05] <PetefromTn> It is kinda convoluted but it simulates fine. Not sure why the G17 is not in the preamble up top there and there does not appear to be any G43 H whatever like I am used to seeing.
[21:36:21] <PetefromTn> yeah I do..
[21:36:22] <Tom_L> you do want G43 Hxx
[21:36:27] <Tom_L> you have cutter comp off
[21:36:29] <Tom_L> G40
[21:36:40] <PetefromTn> Ooh okay I did not do that....
[21:37:01] <Tom_L> G43 is length offset
[21:37:05] <PetefromTn> This post for linuxCNC is pretty messed up ...
[21:37:06] <Tom_L> for the H line
[21:37:08] <PetefromTn> Yeah I know...
[21:37:38] <Tom_L> i don't specify G20 but i've seen alot of guys do that
[21:37:39] <PetefromTn> Lemme try to remove the G40 from the post processor preamble..
[21:38:11] <Tom_L> i dunno what lcnc default is for that
[21:39:25] <toastyde1th> g20/g21 is inch/metric
[21:39:46] <Tom_L> i know but i don't have it output in my post
[21:40:01] <Tom_L> i rely on units in the ini
[21:41:22] <PetefromTn> Okay just removed the G40 from the post and reposted that same code still no G43 H whatever. Not sure why'
[21:43:12] <Tom_L> add it in the start move section
[21:43:52] <Tom_L> in whatever cryptic means they want to see
[21:45:26] <Tom_L> does it allow you to enter 'user events' like op stops to move clamps etc during cuts?
[21:48:02] <PetefromTn> Actually yeah it does. There are two places for things like that. You can add a code snippet in a header or a footer of each machining operation OR you can add a code snippet in general as a custom script.
[21:49:02] <Tom_L> so you can move the table out and M1 to change stuff
[21:49:53] <Tom_L> i use M0 to be safe
[21:57:08] <PetefromTn> sorry had to take out the garbage LOL
[21:57:41] <PetefromTn> Yeah I generally do not use those codes unless there is something specific I need to stop the machine to take care of but yeah you could put them in like that.
[21:58:10] <Tom_L> i'd add the G43 Hx in the tool change section
[21:58:17] <Tom_L> or first move section
[21:58:22] <Tom_L> may be a better place for it
[21:58:28] <Tom_L> since you need a move for it to take effect
[21:58:53] <Tom_L> G43 Z0.1 H1
[21:59:05] <Tom_L> i do that to move to the 'safe' height
[22:00:09] <PetefromTn> Actually the program must callout the H with the tool change but I do not think it is something you can just add in a code snippet like that. It must be able to adjust based on the tool selected.
[22:00:29] <Tom_L> right, that's what my template spits out
[22:00:37] <Tom_L> i don't enter it like that
[22:01:24] <Tom_L> something like: {tool.lengethoffset} H {someoffsetvalue}
[22:01:29] <Tom_L> or such
[22:01:55] <PetefromTn> I think their linuxCNC post is kind of a mess. I mean it ran the drill cycle I posted fine but I setup the single tool off the workpiece with it in the spindle.
[22:02:05] <PetefromTn> Yeah something like that.
[22:02:10] <Tom_L> i don't know their template terminology
[22:02:30] <Tom_L> i could show you mine but it would be greek
[22:02:36] <PetefromTn> Me neither. I was able to edit it to get it where it is now but that was mostly just deleting items.
[22:06:42] <PetefromTn> http://pastebin.com/tG3k4BCk
[22:06:54] <PetefromTn> That is the post processor in notebook.
[22:08:38] <Tom_L> what's $mop.header?
[22:09:01] <PetefromTn> Machining operation header
[22:09:41] <Tom_L> tool change is in it, maybe you put it there
[22:11:33] <PetefromTn> not sure what you mean. the only changes I have made were to remove a bunch of instances where the cutter would go to clearance plain even before the tool callout.
[22:11:56] <PetefromTn> I also installed the G28 in there but just noticed there is no G91
[22:12:03] <Tom_L> i'm trying to figure out where to put the H word
[22:12:39] <Tom_L> also, my template can force mode words even if they're not necessary
[22:13:03] <Tom_L> if it's in G90 i can tell it to ouput a G90 in code anyway
[22:13:12] <Tom_L> or turn that off
[22:13:20] <Tom_L> until the mode changes again
[22:14:41] <Tom_L> #PLANE #MOV #ABSI < X#XPOS>< Y#YPOS> S#SPEED M03
[22:14:44] <Tom_L> puts out:
[22:14:45] <PetefromTn> I think you can pretty much put whatever you want in this post but I am not familiar with the syntax to know where and how.
[22:14:45] <Tom_L> G17 G00 G90 X-0.689 Y-0.0491 S10016 M03
[22:15:10] <Tom_L> the S is random
[22:15:24] <PetefromTn> okay.. so?
[22:15:40] <Tom_L> i don't have a 10k rpm spindle :D
[22:16:08] <PetefromTn> I input the G91 in the post before the G28 and it did not put it in the posted code for some reason.
[22:16:29] <Tom_L> the above example the '<>' means it's optional
[22:16:46] <Tom_L> until it changes, it won't be output
[22:20:28] <PetefromTn> http://pastebin.com/26kDVN6L
[22:20:41] <PetefromTn> That is the code now after I changed it a bit.
[22:22:40] <PetefromTn> This all started with me just wanting to change the post so when the program finished with a mop the tool would go to a toolchange height so I can change it instead of leaving it down in the work where I cannot jog the head up to change tools.
[22:22:54] <Tom_L> make sure your parameters are being set
[22:23:00] <Tom_L> before you use G28
[22:23:15] <PetefromTn> I set the G28 at the machine correct?
[22:23:17] <Tom_L> it reads the values at 5161-5166 for the move
[22:23:28] <Tom_L> home should set them
[22:23:39] <PetefromTn> Oh it goes home then?
[22:23:55] <Tom_L> but since you're having trouble i thought i'd mention that before you put the spindle thru the table
[22:23:55] <PetefromTn> I thought you could change them to whatever you wanted in G28.1
[22:24:16] <Tom_L> i don't use G28.1
[22:24:21] <Tom_L> but i suppose you could
[22:24:59] <PetefromTn> So when I home the machine it sets G28 automatically then and if I callout G28 in the code it will go to home position.
[22:25:05] <Tom_L> yes
[22:25:18] <Tom_L> whatever axis you specify in code
[22:25:24] <Tom_L> put z by itself
[22:25:28] <Tom_L> or you'll regret it
[22:25:34] <PetefromTn> Okay that actually works great because my home is head all the way up and table in center and all the way forward.
[22:25:35] <Tom_L> they move at once
[22:26:01] <Tom_L> if i use it with x and y i put them on a separate line
[22:26:06] <PetefromTn> Homing sequence is Z first then X then Y
[22:26:31] <Tom_L> @END
[22:26:31] <Tom_L> #IF(#U9=1)<***END***>

[22:26:32] <Tom_L> G28 Y0
[22:26:32] <Tom_L> M30
[22:26:38] <Tom_L> that's my end section
[22:26:54] <PetefromTn> Don't understand you are saying you use G28 and then callout positions?
[22:27:15] <Tom_L> has nothing to do with home sequence
[22:27:16] <PetefromTn> I was under the impression all you needed was the G28 and it would go to that position.
[22:27:26] <Tom_L> if you say: G28 X0 Y0 Z0
[22:27:30] <Tom_L> all 3 will move at once
[22:27:45] <Tom_L> bad if you have clamps etc in the way
[22:27:47] <PetefromTn> what if you just say G28
[22:27:55] <Tom_L> you need to specify an axis
[22:28:08] <Tom_L> G28 Z0
[22:28:33] <Tom_L> then if you want to move the table, put it on a separate line
[22:28:40] <PetefromTn> are you sure because I was reading about G28 on the wiki earlier and I did not notice that.
[22:28:41] <Tom_L> like i did above
[22:28:47] <Tom_L> mkay
[22:28:49] <Tom_L> try it
[22:29:19] <Tom_L> it cost me a cutter the first time
[22:29:19] <PetefromTn> not doubting ya man I honestly don't know and would probably prefer not to screw it up.
[22:30:00] <PetefromTn> So my code I just posted using G91 G28 before the toolchange is wrong then...
[22:30:40] <Tom_L> i'm afraid all the axis would move at once
[22:30:43] <Tom_L> BAD IDEA
[22:30:55] <Tom_L> feel free to try it
[22:31:13] <PetefromTn> I agree it is a bad idea but not sure what this SHOULD be..
[22:31:49] <Tom_L> just put a Z0 on the end of i
[22:31:50] <Tom_L> it
[22:32:00] <Tom_L> G91 G28 Z0
[22:32:21] <Tom_L> then if you want to move the table add X and Y on a separate line
[22:32:27] <PetefromTn> and that is machine coordinates for sure?
[22:32:38] <Tom_L> pretty darn sure
[22:32:44] <Tom_L> but
[22:32:46] <toastyde1th> ...?
[22:32:54] <Tom_L> you said your machine wasn't storing the settings
[22:33:05] <PetefromTn> huh?
[22:33:14] <PetefromTn> The machine is working perfectly
[22:33:20] <Tom_L> the 'bug' you were referring to
[22:33:32] <PetefromTn> The problem here is I am trying to get the cam to work with it
[22:33:39] <PetefromTn> Oh you mean the tool table issue.
[22:33:43] <Tom_L> when you shut the machine off, will it return to G54 offset values after you home it?
[22:33:52] <PetefromTn> Yeah that is apparently a bug
[22:34:08] <PetefromTn> I think it will but honestly have not checked.
[22:34:16] <Tom_L> i haven't worked with your machine so i don't know what's going on with it
[22:34:20] <Tom_L> just offering precautions
[22:34:38] <Tom_L> you can look at the file with gedit
[22:34:42] <PetefromTn> To be frank I get lost setting up the tool length offsets before I run it because I am used to Mach3 which is different.
[22:35:09] <PetefromTn> I know I did that. Only problem is it would not save it for me until i closed the program and reopened it.
[22:35:10] <Tom_L> Machine menu -> touch off to workpiece
[22:35:27] <Tom_L> then set all your tools
[22:35:27] <PetefromTn> My mindset is as follows..
[22:35:34] <Tom_L> then set the z fixture offset
[22:35:59] <Tom_L> whatever active tool is set will set to zero
[22:36:19] <Tom_L> when you tell it to go to G54 zero
[22:36:23] <PetefromTn> I put all the tools into the machine one at a time and set their TLO on a 123 block on the table and save that into the tool table. Ensuring the tool in the spindle is the tool number in the window.
[22:36:47] <Tom_L> that's fine
[22:37:01] <PetefromTn> Then I load the program and the material.
[22:37:06] <Tom_L> that sets the tools in relationship to other tools
[22:37:29] <Tom_L> then use the active tool to set the G54 Z zero
[22:37:49] <Tom_L> all the other tools _should_ be set
[22:37:55] <PetefromTn> I usually go ahead and then go to MDI and do an M6Twhatever tool is first and use it to locate the workpiece.
[22:38:14] <Tom_L> that's fine
[22:38:25] <PetefromTn> Then I touchoff G54 zero and run the part.
[22:38:44] <Tom_L> everybody has different ways to set their stuff up
[22:39:00] <Tom_L> but if you wanna use the tool table what i said is how i do it
[22:39:10] <PetefromTn> What happened this morning is I was running a test part with a single tool and wanted to load the rest of the program in another program file.
[22:39:12] <Tom_L> with the G43 H offset values
[22:39:28] <Tom_L> i do that all the time
[22:40:09] <Tom_L> i just check the G54 Z offset to be sure
[22:40:14] <PetefromTn> when I tried to load the program it saw the tool was not in the tool table on the machine so it errored out and I could not open the damn tool table to input it.
[22:40:47] <PetefromTn> On my machine if I do not open the tool table BEFORE I home the machine I cannot open it.
[22:40:55] <Tom_L> yeah, i dunno how it acts if it can't find a tool specified in gcode
[22:41:04] <PetefromTn> Not sure why really.
[22:41:17] <Tom_L> that's apparently a bug because mine works fine that way
[22:41:49] <Tom_L> i set my tool table up to match my cad cam tool table
[22:41:56] <PetefromTn> All it does is pops up a dialogue that says the line number where the tool is first seen and says it is not in the tool table. Then it says hit okay and it does not load the program any further.
[22:43:11] <PetefromTn> Like I said earlier I have the tools in both the Cad and cam (other than the one that screwed me up this morning) and I keep the length and width information that gets used in the machine tool table. The cam table only has the tool diameter and number
[22:44:44] <PetefromTn> Have always done it this way on the old Rf45 and now this machine and it is the easiest way to keep things straight. The Cam only tells it how deep to go from a zero standpoint and the machine sets the proper offsets.
[22:46:35] <Tom_L> sounds reasonable
[22:47:59] <Tom_L> i would manually add the G43 Hxx after the toolchange on the first linear move until you figure out where to put it in your post
[22:48:00] <PetefromTn> I guess it does but you are saying you keep the offset information in both the machine and the cam software?
[22:48:20] <Tom_L> no no
[22:48:28] <Tom_L> just the tools and the diameters
[22:48:46] <Tom_L> you couldn't possibly keep the length offsets in your cam
[22:48:53] <Tom_L> cad cam
[22:49:01] <PetefromTn> Agreed but that is what I thought you were saying.
[22:49:04] <Tom_L> oh
[22:49:13] <Tom_L> sry for the confoozion
[22:49:15] <PetefromTn> so you basically do it the same way I am.
[22:49:22] <Tom_L> sounds like it
[22:50:25] <PetefromTn> So right now I need to figure out how to get the G43 H offsets to be called out in the code by the post.
[22:50:26] <Tom_L> i've fiddled with my post enough to know how to tweak it pretty easy
[22:50:48] <Tom_L> yeah i've been looking thru their docs and can't find it yet
[22:51:08] <PetefromTn> I turned off the G40 in the post and still no callout.
[22:51:09] <Tom_L> that's why i suggested you just add it on the first linear move after the tool change
[22:51:35] <Tom_L> for G41 you may need one of their template words added somewhere
[22:51:48] <Tom_L> i've got a few words i could give em
[22:52:36] <PetefromTn> If you look at my system tree in the tool table it has an default inch toolset and it contains all my tools. I removed the default tools and installed the ones I am using with their number and diameter.
[22:54:14] <Tom_L> on line 20 of the pastebin add Z0
[22:55:45] <PetefromTn> If you look at the post in the system tree for LinuxCNC you can see G codes used apparently and it has G40 still in it.
[22:55:51] <PetefromTn> Okay I will do that now.
[22:56:06] <Tom_L> i don't follow what you want me to look at
[22:56:15] <PetefromTn> Let me ask you a question here.
[22:57:08] <PetefromTn> When my machine homes the switch for the z is up top of the column but the home position is below it by say .050 or so. Once it is homed it goes to that number if I tell it to Z0 it will probably hit the switch.
[22:57:58] <PetefromTn> I cannot recall if once it gets to the home offset position if it calls that zero or not.
[22:58:00] <Tom_L> mine goes to the number just below the switch
[22:58:11] <Tom_L> i offset .1
[22:58:27] <Tom_L> my configs are on my site if you wanna compare
[22:58:33] <PetefromTn> so do you tell it to go to Zo after a G28 then?
[22:58:39] <Tom_L> i would
[22:58:55] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/configs/sherline/
[22:59:06] <Tom_L> those may not be completely current but that part would be
[22:59:12] <PetefromTn> Okay tomorrow I will check to see what it does after I home it I cannot remember.
[22:59:49] <Tom_L> damn maybe i found it..
[23:00:15] <Tom_L> {$tool.length}
[23:00:20] <PetefromTn> I was doing a lot of playing with the CNCsimulatorPRo freeware today in proofing the code before I put it on the VMC.
[23:00:28] <PetefromTn> Oh yeah.
[23:00:44] <Tom_L> P.76 77of the pdf
[23:00:57] <PetefromTn> what PDF?
[23:01:03] <Tom_L> their docs
[23:01:24] <Tom_L> 0.8.9 help file.pdf
[23:01:32] <Tom_L> 0.9.8
[23:02:15] <PetefromTn> Is that accessed thru the programs help or something online?
[23:02:31] <Tom_L> i just downloaded it from their site
[23:03:22] <PetefromTn> when I click on it I get taken to another page on their site with lots of help topics but no page numbers.
[23:03:44] <Tom_L> http://www.cambam.info/doc/CamBam-0.9.8N.pdf
[23:03:59] <PetefromTn> Oops nevermind found it.
[23:04:55] <PetefromTn> Okay so page 76 77 then,
[23:05:17] <Tom_L> 77 mostly
[23:05:27] <Tom_L> Tools - Tool change topic
[23:05:50] <Tom_L> add that to the toolchange post
[23:06:18] <Tom_L> what does {$endcomment} put out?
[23:06:33] <Tom_L> maybe that's the H word? i dunno
[23:07:36] <Tom_L> otherwise specify G43 H{$tool.index}
[23:08:38] <PetefromTn> I am not good with this kind of thing man I can try things one at a time and post a code and see is all I can do kinda trial and error.
[23:08:41] <Tom_itx> G43 does not cause any motion. The next time a compensated axis is moved, that axiss endpoint is the compensated location.
[23:08:47] <Tom_L> from lcnc docs
[23:08:59] <Tom_L> that's why i suggest putting it at the first linear move
[23:09:06] <Tom_L> usually a move to the 'safe' point
[23:09:42] <Tom_L> i'd try the Start Cut section
[23:09:46] <Tom_L> see what that does
[23:10:07] <PetefromTn> not sure what you mean by start cut.
[23:10:22] <Tom_L> it's a section in their post
[23:10:36] <Tom_L> it's empty right now
[23:11:00] <Tom_L> try adding G43 H{$tool.index} in it once to see what happens
[23:11:28] <PetefromTn> Okay standby..
[23:13:52] <Tom_L> or in the MOP right beside the {$toolchange} entry
[23:13:55] <Tom_L> 2nd line of it
[23:14:23] <PetefromTn> http://pastebin.com/MHwRmbHx
[23:15:07] <PetefromTn> it put it in on line 32?
[23:15:08] <Tom_L> didn't output anything there
[23:15:33] <PetefromTn> Hang on I will try the second idea...
[23:15:41] <Tom_L> no.. i see why
[23:15:49] <Tom_L> the first moves are canned cycles
[23:16:13] <Tom_L> where is line 12 output from?
[23:16:21] <Tom_L> that's where you want it to fall
[23:16:45] <Tom_L> find the section that ouputs line 12 and put it there
[23:17:26] <PetefromTn> line 12 is the move to the clearance plane
[23:17:34] <Tom_L> hint: to find sections i put stupid names in each one that will ouput garbage
[23:17:44] <Tom_L> but it finds the section for me
[23:18:02] <PetefromTn> standby
[23:18:25] <Tom_L> then find that section and put the G43 {move to clearance} H{#toolnumber}
[23:18:33] <Tom_L> or whatever it was
[23:20:18] <Tom_L> if you wanna find post sections put stupid words in the post so it ouputs them and you can see where it puts the code
[23:21:06] <PetefromTn> http://pastebin.com/XhmiewiV
[23:21:07] <Tom_L> i'm about done for tonight.
[23:21:43] <PetefromTn> Okay man understand. It seems to have put it down at the bottom for some reason.
[23:22:02] <Tom_L> not where you want it
[23:22:15] <Tom_L> you will find the right section if you do ^^ that
[23:22:39] <Tom_L> you want the move to 'safe' location which is ouput every time
[23:22:54] <PetefromTn> Okay thanks for the tip and the help my friend. It is MOST appreciated.
[23:23:06] <Tom_itx> later
[23:23:14] <PetefromTn> Later man.
[23:29:22] <PetefromTn> Woo hoo I think I got it.
[23:30:30] <PetefromTn> http://pastebin.com/G8qdESc4
[23:34:31] <PetefromTn> actually it looks like the G43 is before the tool callout oops. Just fixed it.
[23:43:38] <Tom_itx> that post isn't correct
[23:47:40] <PetefromTn> Here is the new one...standby
