[00:15:29] <danimal_laptop> $175
[00:15:40] <andypugh> He has no idea...
[00:15:47] <danimal_laptop> with the servo drive and all the hydraullics
[00:15:56] <danimal_laptop> yea....
[00:16:03] <andypugh> Why don't I find bargains like that.
[00:16:12] <andypugh> Put it on eBay and take the month off...
[00:16:22] <danimal_laptop> haha
[00:16:28] <danimal_laptop> no i want it1
[00:16:31] <Tom_itx> ok am i really here?
[00:16:36] <Tom_itx> damn isp
[00:16:36] <andypugh> No, I want it!
[00:16:46] <andypugh> Yes, you seem to be here Tom_itx
[00:16:49] <danimal_laptop> how much is it work, 5k or so?
[00:17:02] <danimal_laptop> has anyone seen Tom_itx today?
[00:17:13] <andypugh> I would expect to see it listed at 5k second hand, and 20k new.
[00:17:14] <danimal_laptop> worth*
[00:17:28] <danimal_laptop> yea thats my guess
[00:17:37] <Tom_itx> i'd give you $175 for it
[00:17:45] -!- jstenback has quit [Quit: ZNC - http://znc.in]
[00:17:45] <andypugh> But the ones you see on eBay for that kind of money do hang around a wjile.
[00:17:48] <danimal_laptop> it has glenteck servos, about 400oz/in
[00:18:15] <Tom_itx> 2 rotary axis?
[00:18:23] <andypugh> Most Imperial units I am OK with, but I _hate_ oz.in
[00:18:29] <danimal_laptop> yea, 4th/5th axis
[00:18:48] <Tom_itx> what are you gonna use it for?
[00:18:56] <andypugh> Gloating, it seems
[00:19:03] <Tom_itx> apparently
[00:19:12] <danimal_laptop> ha
[00:19:29] <Tom_itx> i like that cabinet too
[00:19:30] <danimal_laptop> hey im excited and you guys are the only ones i know who actually know that it is!
[00:20:03] <danimal_laptop> andypugh: 2.8nm
[00:20:18] <danimal_laptop> Tom_itx: the small one with the monitor sitting in it?
[00:20:48] <andypugh> It looks about the right size for your VMC too.
[00:20:51] <Tom_itx> http://www.flickr.com/photos/66828621@N02/6420920671/in/photostream/
[00:21:21] <danimal_laptop> ah yea thats going to be for my power supply and spindle drive and SSR's
[00:21:35] <Tom_itx> yeah i figured
[00:21:39] <Tom_itx> that's what i need for mine
[00:21:42] <danimal_laptop> andypugh: it's got a 6.5" faceplate
[00:22:08] <danimal_laptop> Tom_itx: wish you were closer, there's tons of them there

[00:22:17] <Tom_itx> set those in the bottom of it
[00:22:20] <Tom_itx> 3 of em
[00:22:30] <Tom_itx> along with the mesa cards and the atom
[00:22:34] <danimal_laptop> yea itd be perfect for that
[00:22:43] <Tom_itx> how much?
[00:22:44] <danimal_laptop> eh, a little crowded for that too
[00:22:46] <andypugh> You will need to branch out into a less two-dimensional product :-)
[00:23:00] <danimal_laptop> i got it for $30
[00:23:02] -!- jsr has quit [Remote host closed the connection]
[00:23:10] <danimal_laptop> andypugh: i know!
[00:23:20] <danimal_laptop> thats just what i needed to do so
[00:23:31] <Tom_itx> it would cost at least that to ship one here
[00:23:43] <danimal_laptop> yea, but they're $300 new
[00:23:51] <danimal_laptop> or so
[00:23:58] <Tom_itx> how heavy is it?
[00:24:06] <Tom_itx> like an electrical box?
[00:24:10] <danimal_laptop> i dunno, 40lbs?
[00:24:14] <danimal_laptop> yea
[00:24:14] <Tom_itx> yeah
[00:24:21] <danimal_laptop> hoffman enclosure
[00:24:39] <Tom_itx> is that little one metal too?
[00:24:46] <Tom_itx> it almost looks plastic
[00:25:05] -!- theorbtwo has quit [Ping timeout: 260 seconds]
[00:25:49] <Danimal_garage> metal
[00:25:55] -!- Loetmichel [Loetmichel!Cylly@p54B14F32.dip.t-dialin.net] has joined #emc
[00:26:04] <Danimal_garage> they got a pallate of those there. i just got another one for my other mill
[00:26:23] <Danimal_garage> perfect for the touch screen and buttons
[00:26:24] <Tom_itx> i wonder what shipping would be on that
[00:26:48] <Danimal_garage> no clue
[00:27:06] <Danimal_garage> 40-50 maybe
[00:27:15] <Danimal_garage> still way cheaper than a new one
[00:27:38] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/SBC/box.jpg
[00:27:42] <Tom_itx> that was $45
[00:27:44] <Danimal_garage> i left a huge one at the surplus yard... probably 5'x3'x15"
[00:27:46] <Tom_itx> from seattle

[00:28:11] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/SBC/inside_control.jpg
[00:28:17] <Tom_itx> with 5 or 6 of those in it
[00:28:43] <Tom_itx> what's the dimensions on that one?
[00:29:34] <Tom_itx> the problem with electrical boxes is they are made to flush mount to a wall which makes em too thin
[00:30:32] <Danimal_garage> these arent
[00:30:41] <Danimal_garage> they're enclosures for machines and whatnot
[00:30:49] <Tom_itx> i know, they're machine enclosures
[00:30:52] <Tom_itx> :)
[00:31:07] <Danimal_garage> 12x20x24"
[00:31:27] <Tom_itx> 12 deep is pretty nice
[00:31:27] <Danimal_garage> they got a ton of different sizes
[00:31:32] <Danimal_garage> yea
[00:31:50] <Tom_itx> 6 - 8 would be plenty for me
[00:31:55] <Danimal_garage> they got some i can easily fit inside
[00:32:02] <Danimal_garage> thats what she said

[00:32:38] <Danimal_garage> i may go back and pick up that big one, and weld some shelves into it and use it as a storage cabinet lol
[00:32:49] <Tom_itx> good idea
[00:32:58] <Danimal_garage> it was on the machine i got the 5tg axis out of
[00:33:03] <Danimal_garage> 5th
[00:33:05] -!- kp has quit [Ping timeout: 244 seconds]
[00:33:16] <Danimal_garage> so i already paid for it
[00:33:21] <Danimal_garage> technically
[00:33:22] <Tom_itx> did that one come with the insides in it?
[00:33:27] <Danimal_garage> yes
[00:33:40] <Danimal_garage> they usually take out the expensive stuff unless you want it
[00:33:52] <Danimal_garage> that one had a big plc and power supply in it
[00:34:06] -!- kp [kp!~kostas@iststud.static.otenet.gr] has joined #emc
[00:34:06] <Danimal_garage> they wanted $100 for everythnig
[00:34:16] <Danimal_garage> but i said i just wanted the case
[00:34:16] <Tom_itx> 70v 20A supply would be nice
[00:34:21] <Danimal_garage> ha
[00:35:40] <Tom_itx> does it have any punchouts for a fan?
[00:35:53] -!- theorbtwo [theorbtwo!~theorb@] has joined #emc
[00:36:21] <Danimal_garage> no holes except for the 4 factory ones in the back
[00:36:41] <Tom_itx> dimples for mounting?
[00:36:53] <Tom_itx> or flat...
[00:37:02] <Danimal_garage> flat i imagine
[00:37:05] -!- FinboySlick [FinboySlick!~shark@squal.net] has joined #emc
[00:37:06] <Danimal_garage> didnt look
[00:37:11] <Danimal_garage> usually they're flat
[00:37:40] <Danimal_garage> i picked up a small one today also, maybe 6x8x8
[00:37:57] <Tom_itx> that's a little small
[00:40:05] <Danimal_garage> i havent opened it yet, might have a plc in it

[01:33:53] <Tom_itx> this hasn't crapped out since i did
[01:33:56] <Danimal_garage> you find a loose one
[01:33:59] <Danimal_garage> ah
[01:34:01] <Danimal_garage> lol
[01:34:02] <Tom_itx> not really
[01:34:14] <Tom_itx> they still say the signal is bad though
[01:34:44] <Danimal_garage> for what?
[01:34:58] <Tom_itx> the cable modem

[01:50:37] <Tom_itx> http://www.linuxcnc.org/docs/2.5/html/gui/axis.html
[01:51:37] <tom3p> thats the top, and i'd like to see the bottom ( heekscnc read it but added a bazillion arcs larger than the plot )
[01:52:19] <tom3p> so i been looking at other render-ers hoping to see it from underneath.

[01:55:31] <jtektool> i fixed it but it seems distfiles.gentoo.org/distfiles no longer contains patch2.6.34.5.bz2
[01:56:04] <jtektool> latest in this branch is patch2.6.39.4.bz2
[01:56:16] <jtektool> should i change the wiki?
[01:57:27] <jtektool> also figured going to kernel 3.x would marr things up real bad so havent attempted that
[01:57:39] <jtektool> anybody got any input?

[02:26:01] <danimal_laptop> 99% sure its iron
[02:26:37] <danimal_laptop> it had some light surface rust on it and the way it cleaned off made me think iron

[02:27:37] <tom3p> very nice score tho
[02:28:28] <Danimal_garage> i wiped it down a little with a pad
[02:28:43] <Danimal_garage> im pretty stoked
[02:29:07] <Tom_itx> you got lotsa toys to get working now
[02:29:17] <Danimal_garage> no shite, huh
[02:29:38] <Danimal_garage> mill might be running in a week or 2
[02:29:43] <Tom_itx> what do the hydraulics do on the rotary?
[02:30:08] <Danimal_garage> its a brake system
[02:35:30] <tom3p> i dont know how/if emc2 handles that.
[02:35:37] <tom3p> in most cncs if you turn on the brake ( to hold something dead steady ), you remove the axis from closed loop.
[02:35:37] <tom3p> if you want it back under cnc control, you have to make sure the brake is off and the position is known.
[02:37:20] <Danimal_garage> im sure it can be figured out

[03:26:19] <danimal_laptop> hmm worked ok.
[03:26:32] <danimal_laptop> .015" depth of cut
[03:28:06] <Tom_itx> well if the tools are sharp and the feeds are right it cuts

[03:39:13] <jtektool> i should i urn off acpi in my kernel right
[03:43:40] <mozmck> You can leave it enabled, but turn off everthing except Button and I think Dock has to stay on.
[03:44:41] <jtektool> thanks
[03:46:48] <jtektool> what is dock kernel parameter anyways
[03:49:48] <jtektool> hope this works couldnt wait to get away from ubuntu
[03:50:11] <jtektool> all this automagick stuff screws with my head
[03:51:19] <jtektool> its an atom anyways odd that latency is 5000 on such a low end system
[03:51:30] <jtektool> dont need much power management lol
[03:51:43] <mozmck> I don't know for sure, but I thing it was grayed out.
[03:51:49] <mozmck> think
[03:53:19] <mozmck> You may be better off just disabling acpi altogether, I can't remember all it did.
[03:54:43] <jtektool> well its making right now i should your right and go back in and tweak after i got a running system
[03:55:05] <jtektool> thats usually how i roll and get the bare minimum first and go in and tweak later
[03:55:33] <jtektool> <<<running with rtai that is
[03:56:17] <mozmck> Yeah.
[03:57:08] <jtektool> (babbling) ssh is great...you can work in your underwear!
[03:58:12] <mozmck> You might check before disabling acpi altogether, I seem to remember it being needed for SMP or something along those lines.
[03:58:27] <Danimal_garage> success! the broaching worked.
[03:58:33] <Danimal_garage> a little slow...
[03:58:55] <Tom_itx> what type of broach is it?
[03:59:08] <Danimal_garage> 1/4" keyway
[03:59:36] <Danimal_garage> i made a shaping tool out of an endmill and put it in the boring bar holder in my cnc lathe
[03:59:53] <Danimal_garage> and just kept making passes
[04:00:01] <Danimal_garage> spindle off and locked

[04:07:47] <jtektool> ok checked hardware database on wiki and they turned off hyperthreading in bios and isolated 2nd cpu in grub but enabled smp (same motherboard /cpu)
[04:08:25] <jtektool> and your right you have to leave acpi on with an atom to get smp
[04:08:44] <jtektool> thanks a bunch mozmck
[04:09:41] <mozmck> np. I believe you have to leave acpi on for smp on any dual+ core/processor system.
[04:10:17] <jtektool> haha its still compiling
[04:10:36] <jtektool> weird tho this atom board is among the best for jitter on the whole wiki
[04:10:57] <jtektool> it was 71$ with a cpu lol

[16:18:54] <ssi> ugh my compressor seems to have died D:
[16:21:15] <syyl_> hehe, today i got our tig welding equipment up and running ;)
[16:21:16] <syyl_> http://dl.dropbox.com/u/24396704/2011-12-01_14-39-47_822.jpg
[16:21:18] <syyl_> finally
[16:21:48] <jdhNC> about damned time.
[16:22:14] <syyl_> the welder was standing around for two month...
[16:22:28] <syyl_> no table, no power on the welding place, no gas, no nothing...
[16:22:45] <jdhNC> I had a dead welder this morning (automatic tube welding machine)
[16:23:07] <syyl_> tube welding machine? what does it?
[16:23:10] <jdhNC> turned out it was a bad torch hose
[16:23:12] <syyl_> dont say "it welds tubes"
[16:23:15] <syyl_> ;)
[16:23:21] <jdhNC> welds plugs on tubes
[16:23:44] <syyl_> ah, ok
[16:23:45] <jdhNC> then measures them, then does 100% ultrasonic inspection
[16:24:50] -!- Turtl3boi has quit [Ping timeout: 252 seconds]
[16:25:19] <syyl_> is it oxy-acetylene welding?
[16:26:00] <jdhNC> nah, it's TIG
[16:26:30] <syyl_> automated tig welding? didnt know that such exists :o
[16:27:11] <jdhNC> turned out the torch cable had an internal break. Enough connection for the arc starter to try really hard to establish the arc, but not enough for any curent to sustain the arc
[16:28:25] <ssi> there's tons of robot tig welders
[16:28:59] <ssi> haha this is what I asked for for christmas:

[16:30:08] <syyl_> ;)
[16:31:11] <jdhNC> I'll send you 4 sets of harbor freight badly cast pliers instead.
[16:31:12] <syyl_> also love the wire cutters from knipex
[16:31:21] <syyl_> its really hard to ruin them
[16:31:27] <ssi> I haven't tried the wire cutters
[16:31:32] <syyl_> horrible freight? ;)
[16:31:33] <ssi> I have some slip joint pliers
[16:32:16] <ssi> something like this:

[16:32:32] <syyl_> jip
[16:32:39] <syyl_> know them :)
[16:32:49] <syyl_> knipex is absolute common here...
[16:32:56] <ssi> lucky ;)
[16:32:58] <syyl_> at work we dont order other brands
[16:33:06] <syyl_> and in my homeshop..same thing :D

[17:33:20] <danimal_laptop> on a knee mill where you only have 5 inches or so of quill travel, is there a way in emc to change the hight of the knee for different work offsets, assuming you are able to drive it and have a scale or encoder on it?
[17:34:25] <danimal_laptop> so if the z work offset difference between g55 and g57 is -1", the knee moves the 1" and the quill still has the 5 inches of travel
[17:35:42] <cradek> if I had that mill, I'd put tool length offsets onto the knee, so you'd always be able to cut 5" deep with every tool, no matter its length
[17:36:00] <cradek> also you only have to wait for the slow knee to move once per tool
[17:36:22] <cradek> tool table like this: T1 P1 W1.234

[17:38:04] <danimal_laptop> that wouldnt work for what im thinking... on the 5th axis, i dont think i'd have enough quill travel to machine stuff on the table, on the 5th axis in the horizontal position, and in the vertical position
[17:38:25] <danimal_laptop> although that is a good idea for tool offsets
[17:38:44] <cradek> guess I don't understand your setup
[17:39:02] <danimal_laptop> well i want to be able to machine on the table and on top of the 5th axis
[17:39:24] <danimal_laptop> in one program
[17:39:28] <danimal_laptop> if needed
[17:39:42] <danimal_laptop> that's more than the quill's travel
[17:40:24] <cradek> why not just use a g5x coordinate system with W offset
[17:40:42] <cradek> g58; g0 w0 (table moves down)
[17:40:54] <cradek> g57; g0 w0 (table moves back up
[17:41:00] <danimal_laptop> hmmm
[17:41:04] <cradek> it's just a fixture like any other at a different "height"
[17:41:05] <danimal_laptop> wasnt aware of W
[17:42:27] <danimal_laptop> it would be nice if just changing the work offset would do it though, rather than having a full on 6th axis
[17:43:44] <cradek> I think the more interesting case is handling a manually-controlled knee only scale feedback
[17:44:03] -!- Zanerkin has quit [Quit: Leaving]
[17:44:12] <cradek> the setup you describe (nice controlled motorized knee) doesn't present any challenge IMO, you can handle it many ways
[17:44:26] <danimal_laptop> yea, the knee already is motor driven
[17:44:37] <danimal_laptop> has limit switches, etc
[17:44:45] <cradek> on my old non-emc knee mill, I had tool table entries for "short" and "long" which required the knee to be moved
[17:45:01] <cradek> it was a big pain, but worked
[17:45:05] <danimal_laptop> hmm
[17:45:50] <cradek> loading T4,5,6? crank knee down 2" if it's up -- loading 1,2,3? crank up 2" if it's down
[17:46:21] <cradek> this mill didn't have the equivalent of multiple G5x
[17:46:28] <danimal_laptop> i guess if i made the knee an axis, i can just touch off that axis and make that the only difference in that work offset (keep z the same as the previous work offset)
[17:46:37] <cradek> only had one origin, plus tool offsets
[17:46:53] <cradek> yes exactly
[17:46:56] <cradek> very simple

[17:48:52] <danimal_laptop> yea
[17:48:58] <danimal_laptop> 6.5" faceplate
[17:49:05] <cradek> where's the encoder?
[17:49:16] <danimal_laptop> on the servos i think
[17:49:29] <cradek> cool
[17:49:31] <danimal_laptop> its got 2 glentek 400oz/in servos
[17:49:49] <danimal_laptop> hydraulic brakes
[17:50:15] <cradek> is it in working order?
[17:50:21] <danimal_laptop> no clue
[17:50:32] <danimal_laptop> it was part of some home made machine
[17:50:49] <cradek> you're going to have trouble with not enough quill travel
[17:50:55] <danimal_laptop> the plc in the machine was said to be bad
[17:51:17] <cradek> maybe you should use the knee for Z and use quill just for TLO
[17:51:20] <danimal_laptop> so i got the whole machine for cheap and stripped out this and the servo drive for it
[17:51:38] <danimal_laptop> cradek: i dont know if the knee has a ballscrew yet
[17:52:36] <cradek> is it this? http://www.flickr.com/photos/66828621@N02/6384358423/in/photostream/
[17:52:38] <danimal_laptop> i figured i could just use different work offsets
[17:52:50] <danimal_laptop> yes
[17:52:58] <cradek> that's not a servoed table I bet
[17:53:04] <cradek> er knee I mean
[17:53:12] <danimal_laptop> no
[17:53:12] <cradek> I bet there were just up/down buttons
[17:53:27] <cradek> is it a dah-lih?
[17:53:32] <danimal_laptop> kasuga
[17:53:46] <danimal_laptop> there's a toggle switch on the front

[18:51:36] <PCCNC123> what is the main difference between PC based CNC and Industrial CNC control like Fanuc siemens?? except hardware design?? i mean to say any performance tradeoff???
[18:52:18] <IchGucksLive> the Price B)
[18:52:28] <PCCNC123> for example if we use good hardware with EMC2 than is there any drawback/lack of features???
[18:52:31] <IchGucksLive> Simens is a Dos controled system
[18:52:38] <jdhNC> emc2 is open, you can change what you don't like and verify it does what you want
[18:53:17] <PCCNC123> jdhNC, i am talking about trajectory planning etc...
[18:53:45] <andypugh> If you don't like the TP, you can change it...
[18:53:46] <PCCNC123> IchGucksLive: u sure siemens is Dos control system???
[18:54:26] <PCCNC123> andypugh i just know the term TP , i cant program it .. ha ha ha..
[18:54:38] <IchGucksLive> Yes startup a (10 and you see the dosprompt for starting if you interact Pacman will run on your mashine
[18:54:56] <PCCNC123> are you talking about 802D???
[18:56:38] <PCCNC123> andypugh: if we use MESA's higesht performance card? than can we compare result with their starting controller like 802 810 series??? just for my knowledge m asking.. acutally someone asked me today and i was not able to give satisfactory answer
[18:56:52] <PCCNC123> in terms of performance only..
[18:57:00] <cradek> the question is too broad to have an answer
[18:57:37] <PCCNC123> i found one comparision chart on wiki but i think its too old and lack of info...
[18:57:39] <cradek> also, none of us have used all industrial cnc controls
[18:58:07] <jdhNC> I can't imagine one could be so superior to the rest
[18:58:11] <cradek> I bet each of them has some thing they do best, and I bet emc does too
[18:58:16] <PCCNC123> cradek: comparision with any of them if anyone have ever did.. like Fanuc Siemens HAAS, HURCO
[18:58:59] <cradek> emc has been better than the original control of every machine I've personally retrofitted
[18:59:11] <cradek> however the newest machine I've personally done was 80s technology
[18:59:15] <PCCNC123> for example?
[18:59:46] <cradek> the commercial-type machines in my shop were originally yasnac and GE controls
[19:00:52] <PCCNC123> ok. what is the test benchmark?? i will have 802S or D next month??
[19:00:54] -!- mhaberler has quit [Quit: mhaberler]
[19:01:00] <PCCNC123> i mean what should i check over it??
[19:01:04] <PCCNC123> except speed
[19:01:13] <andypugh> PCCNC123: The question is complicated. Are you asking about EMC2 as a controller software, or an EMC2-based system, including all the hardware?
[19:01:31] -!- bootnecklad [bootnecklad!~bootneckl@vm4.telegraphics.com.au] has joined #emc
[19:01:42] <PCCNC123> is there any good Gcode you suggest for turning which i can run on both and see the result
[19:01:54] <cradek> all possible answers "emc is better than all those" "emc is worse than all those" "they are all equivalent" are equally facile
[19:01:57] <PCCNC123> andypugh i am talking about EMC2 as a controller
[19:02:10] -!- theorbtwo has quit [Ping timeout: 260 seconds]
[19:02:27] <PCCNC123> not whole system.. coz whole system depends on lot of things which can vary from person to person who installed it..
[19:02:33] <IchGucksLive> PCCNC123: the S have less interacts and cycles
[19:02:35] <andypugh> The lack of lathe-roughing cycles in EMC2 is a difference which should be admitted to. But then I don't know if Fanuc can write condiitonal loops in the G-code
[19:03:10] <cradek> yes lathe cycles are a big way some controls exceed emc2/lathe's capability
[19:03:21] <andypugh> PCCNC123: You mentioned the Mesa cards (don't forget Pico, too) so I wasn't clear what you were discussing.
[19:03:24] <cradek> rigid tapping is a big way emc2 exceeds some commercial controls
[19:03:27] -!- Turtl3boi [Turtl3boi!~chatzilla@ip72-199-20-172.sd.sd.cox.net] has joined #emc
[19:03:58] <andypugh> And it is a lot easier for someone to add lathe roughing to EMC2 than to add rigid tapping to Fanuc
[19:04:13] <PCCNC123> i was discussing good pulse/enc speed and performance... i thought mesa PCI can deliver it..
[19:04:38] <cradek> if you mean can emc move the axes as fast as the original control, the answer is positively yes
[19:04:44] <IchGucksLive> Fanuc has internel G-code cycles programmed
[19:04:47] <andypugh> Yes, Mesa, Pico and Motenc can all count encodes faster than any practicalo machine can make them.
[19:04:51] <PCCNC123> that is interpreter side, and emc2 is open so any good programmer can do it..
[19:04:52] <IchGucksLive> the same has haas does
[19:05:03] <PCCNC123> what about actual machining...
[19:05:09] <Tom_itx> anybody ever try replacing a laptop power jack on the mb?
[19:05:28] <andypugh> Tom_itx: A few times. It's easy. CHeck eBay for the parts
[19:05:30] <jdhNC> tom: you should have no problem
[19:06:17] <IchGucksLive> Tom_itx: there are video Howtoos
[19:06:25] <PCCNC123> any lack of major G-Code in EMC2??
[19:06:32] <jdhNC> the jack is easy, getting to it sucks
[19:06:56] <cradek> PCCNC123: emc2's gcode is different, just like all controls are different from one another
[19:07:31] <Tom_itx> andypugh i found one
[19:07:35] <cradek> PCCNC123: emc2's gcode is sort of like fanuc until you get into esoteric areas
[19:07:35] <IchGucksLive> PCCNC123: im iss the G12/13 G150 of Haas most
[19:07:50] <IchGucksLive> PCCNC123: but i did my own routines
[19:07:57] -!- mhaberler [mhaberler!~mhaberler@] has joined #emc
[19:08:41] <PCCNC123> cradek any test bench you suggest for Turning??? i mean complex shape etc...
[19:09:03] <andypugh> IchGucksLive: You can add your own G-codes now...
[19:09:07] <PCCNC123> i know it should be done in Milling, but i am not having 3 axis controller of fanuc siemens etc
[19:09:11] <cradek> no shape is harder than any other...
[19:09:25] <jdhNC> you have a machine with a standard control that you can just disconnect and hook up to an emc2 box?
[19:09:26] <andypugh> So you could call your G12 G-code sub with "G12"
[19:10:11] <PCCNC123> andypugh:how to add our own GCODE?? does it require extensive programming???
[19:10:49] <IchGucksLive> andypugh: not realy its the python interface
[19:10:52] <andypugh> No, if the routine exists as G-code, it is just an INI file change. I think this is Master only. mhaberler !
[19:11:02] <PCCNC123> hey one more imp thing i forget .. PLC.. i think they all have inbuilt PLC
[19:11:20] <mhaberler> please consult the 'Extending EMC' section in the manual.
[19:11:25] <andypugh> IchGucksLive: I think you can link a G-code to Python too.
[19:11:31] <Tom_itx> IchGucksLive i doubt i need a video, i just wondered if it was that common to fix
[19:11:32] <IchGucksLive> yes
[19:11:35] <PCCNC123> i came accross classicladder but never used it..
[19:11:58] <PCCNC123> is it in development stage or mature??
[19:12:05] <mhaberler> mature
[19:12:43] <Tom_itx> andypugh you don't have a good source for plugs?
[19:12:52] <Tom_itx> i found a couple but they vary alot in cost

[19:16:31] <Tom_itx> i have 3 identical laptops
[19:17:11] <Tom_itx> for that i can get a couple spares
[19:17:29] <andypugh> Tom_itx: Another auction had a lot of 10 for $15
[19:17:57] <Tom_itx> i don't need 10
[19:18:14] <andypugh> Tom_itx: Sounds like you might, in time.
[19:18:21] <Tom_itx> :)
[19:18:24] <Tom_itx> let's hope not
[19:18:40] <andypugh> IchGucksLive: Those codes sound well suited to a remap/extension
[19:18:56] <IchGucksLive> Tom_itx: what about a profesionell fix for 50USD
[19:19:04] <Tom_itx> i'm not a pro?
[19:19:13] <Tom_itx> local wanted $150
[19:19:15] <IchGucksLive> andypugh: thats why i made them
[19:19:33] <IchGucksLive> Tom_itx: thats way to match
[19:19:51] <andypugh> cradek: Is it possible to spawn-off a separate interpreter instance? It seems to me that lathe-roughing would need to parse a sub into a profile, then generate the moves.
[19:20:06] <Tom_itx> IchGucksLive yes i know
[19:20:21] <Tom_itx> i have the tools to fix it
[19:20:29] <jdhNC> wouldn't lathe roughing be better implemented in CAM or as a g-code preprocessor?
[19:20:57] <andypugh> I don't have any CAM..
[19:21:16] <jdhNC> then for you, HAM
[19:21:22] <cradek> andypugh: I bet there are several approaches to the problem...
[19:21:25] <IchGucksLive> andypugh: Heekscad makes good progress
[19:21:50] <IchGucksLive> ok i go of Thanks and till next time

[19:22:08] <andypugh> You don't necessarily need CAM for a lathe. I just use face/bore/turn/thread macros that are pre-defined.
[19:22:31] <Tom_itx> i have lathe cam and have never used it
[19:22:57] <andypugh> But the idea of drawing a profile in G1/G2/G3 and then having it appear some time later is appealing.
[19:33:56] <Tom_L> andypugh, have you tried ngcgui for the lathe?
[19:37:10] <jdhNC> speaking of turning... I would like to turn this profile. How many tool changes would it require? http://www.artichoke.org/scrubber-lid.pdf
[19:37:37] <jdhNC> or could the inner cut be done with a single tool?
[19:37:58] <JT-Shop> a face grooving tool will cut that
[19:39:08] <Tom_L> JT-Shop, does ngcgui work good for lathe?
[19:39:22] <mhaberler> andypugh: I am working on that as you ask, and it works fine
[19:39:33] <JT-Shop> extremely well for me, I do 95% of my work using it
[19:39:54] <Tom_L> i haven't loaded it yet so i didn't know if it was mill only
[19:40:07] <Tom_L> i think it would be ideal for a lathe

[20:46:43] <cradek> ewe know how eye am
[20:47:33] <andypugh> Well, the machines are called slotters, and you often see slotting heads for mills (it's very common to have one on the back end of a bridgeport)
[20:48:14] <andypugh> And here is the very same process called broaching http://www.youtube.com/watch?feature=endscreen&NR=1&v=iO81YZsUc_4
[20:48:16] <andypugh> Hmm..
[20:48:37] <cradek> I feel like calling it broaching is wrong
[20:49:11] <andypugh> Yes, to me a broach makes several cuts per pass, generally of the same shape as the broach
