[02:03:16] <Jymmm> JT-Shop: I can help taking down the walls, I'm good at that! You got a bomb suit?
[02:04:39] <elmo40> Jymmm: what's wrong with driving through it
[02:06:41] <Jymmm> elmo40: No explosives involved, and where's the fun in that?
[02:11:39] <elmo40> driving a bull dozer would also be fun :)
[02:13:53] <Jymmm> No purrrrrty lights that way
[02:14:32] <elmo40> only a yellow one
[02:14:51] <jdhNC> someone should have a big field with bulldozers, backhoes, etc that you could pay to go play with
[02:15:28] <elmo40> you can get paid to play... work for a demo company
[02:15:46] <elmo40> or construction... same difference sometimes :-P
[02:17:04] <jdhNC> then it would be work and no fun

[04:18:54] <l0st1nsp4c3> hey guys quick question i just finished wiring up my g540 and my stepper motors (haven't yet played with the fine tuning of the g540 per motor) all works well all axis move etc etc....but one motor once in a while once it stops moving and holding torque takes over sometimes chirps?!?!?!
[04:19:20] <l0st1nsp4c3> is this a sign of an issue with the motor? issue with the trimpot on the g540 for that axis needing adjustment??

[09:12:30] <scanf> what 3d modeling program do you all recommend
[09:12:39] <scanf> for a n00b
[09:13:06] <Valen> rhino ;->
[09:13:17] <Jymmm> Playdoh
[09:14:08] <Jymmm> scanf: http://www.mackiev.com/kidpix/index.html
[09:15:15] <Jymmm> scanf: http://www.mackiev.com/kidpix/kp3d_3dgallery.html
[09:15:49] <scanf> that is oss?
[09:15:49] <Jymmm> scanf: it even has fuzzy bunnies, how can yo not want that?!
[09:17:11] <syyl> rhino is a great modeler
[09:17:16] <syyl> and easy to learn
[09:17:29] <scanf> how much is it
[09:18:48] <Valen> ~$1000 last i heard
[09:19:07] <syyl> single user license around 1000eur
[09:19:18] <syyl> or 1000$
[09:19:39] <syyl> educational license about 200
[09:19:41] <Valen> though it can be "found" somewhat "cheaper" if you "know where to look" *cough*
[09:19:56] * Jymmm lol @ Valen
[09:20:10] <syyl> there is also a demo, that is fully functional
[09:20:19] <syyl> but can save only 25 times
[09:20:58] <syyl> blender is also a free modeling tool
[09:21:02] <scanf> and it can export gcode?
[09:21:15] <syyl> but i would not recomend it as "easy" or "beginner friendly"
[09:21:20] -!- mhaberler [mhaberler!~mhaberler@extern-184.stiwoll.mah.priv.at] has joined #emc
[09:21:34] <Valen> you can get rhinocam which will do gcode
[09:21:35] <syyl> uhm, for gcode, i think, you need a seperate cam-module
[09:21:54] <Jymmm> So you load it on a VM, take a snapshot, when you get to 25 times, revert snapshot and repeat.
[09:22:03] <syyl> hehe
[09:22:47] <syyl> for gcode you could also use cambam
[09:23:02] <syyl> it can import .stl models

[10:16:45] <alex_joni> scanf: try looking at Alibre
[10:16:58] <alex_joni> they had some cheapish cad/cam bundles for at home
[10:21:50] <alex_joni> http://www.alibre.com/products/hobby/
[10:22:38] <elmo40> scanf: do you need a 3D modeler? most tool paths are 2D. Try Inkscape with the gcode plugin. 3D drawing with HeeksCNC. isn't too bad but only a 2D tool path is possible (atm)
[10:23:21] <AC-130H> hmm
[10:23:58] <AC-130H> looking at linuxcnc... makes me wonder if there is any such way to make it embedded
[10:25:51] <scanf> elmo40, i am just trying to draw things to make with my cnc router out of al/wood/plastic
[10:26:05] <scanf> unfortunately i dont know how to draw/draft
[10:26:18] <syyl> do you realy need 3d capability?
[10:26:25] <syyl> or is 2,5D enough
[10:27:24] <scanf> prob just 2.5D
[10:27:40] <syyl> then you should look at sheetcam :)
[10:28:02] <syyl> runs on windows/linux, is relative cheap and works great
[10:28:21] <syyl> and for drawing you could use Qcad
[10:30:59] <scanf> say i am trying to build parts for a robot arm
[10:31:13] <scanf> what steps would i take to mill it out of my workpiece
[10:31:55] <syyl> draw it in a cad program
[10:32:04] <syyl> import it in a cam software (or maybe the cad has one integrated), to create the toolpaths
[10:32:40] <syyl> in the cam you make all the settings for milling, which cutter you want use, feeds and speed, cutting depht, etc..
[10:33:13] <syyl> then, the cam can export the toolpaths as a gcode file
[10:33:48] <archivist> or write the gcode by hand
[10:33:53] <syyl> yeah
[10:34:07] <syyl> thats of course also a possibility :D
[10:34:21] <jthornton> scanf: what kind of things are you milling artsy stuff or geometric shapes?
[10:35:06] <scanf> artsy
[10:35:47] <jthornton> kinda hard to do by hand then
[10:39:44] <scanf> id also like to do pcbs
[10:39:47] <archivist> unless geometric artsy :)
[10:39:49] <scanf> lets say first project pcbs
[10:39:56] <scanf> slash geomtric slash artsy
[10:40:41] * jthornton has started a bunch of times to write a dxf to g code converter but never has finished one :/
[10:55:34] <archivist> jthornton, like I started a gerber to gcode, got as far as decoding the gerber
[10:55:49] <archivist> mooore roun tuits needed
[10:56:02] <jthornton> that's about how far I get parsing the dxf file
[10:57:41] <jthornton> I wonder how this one works http://code.google.com/p/dxf2gcode/
[11:00:11] <jthornton> this one was started by micges http://sourceforge.net/projects/vec2ngc/

[11:00:46] <archivist> I got this far http://kicad.archivist.info/pcb/readgerber.php?gerberfile=CapnKernel-doodad%2Fkicad%2Fdoodad-Component.pho
[11:01:17] <archivist> its shows the decoded gerber live. done in php
[11:03:49] <syyl> for pcbs, i prefer eagle with the mill-outlines.ulp
[11:04:53] <jthornton> dxf2gcode seems to work but it is stuck in mm
[11:05:30] <awallin_> archivist: can you read gerber and get line/arc output? I would be interested in complex pcbs for testing 2D offset CAM code at some point
[11:07:54] <archivist> lines are drawn with a flash (specified diameter) Kicad includes the flash data it uses, older stuff has a separate flash definition
[11:08:58] <jthornton> dxf2gcode can send the output directly to Axis :)
[11:09:38] <archivist> I currently read the .gbr and draw on a canvas/image, it could output vector,. but it is already a vector form

[11:34:51] * jthornton finds dxflib a c++ lib for reading and writing dxf files :)
[11:44:48] <scanf> is there a pcb milling bible somewhere
[11:44:56] <scanf> my cnc is breadboarded
[11:45:18] <scanf> so maybe for my first project i should design and mill a pcb
[11:51:39] <jthornton> well, dxf2gcode works very well
[11:54:29] <archivist> what do you mean by complex pcb by the way
[11:55:29] <awallin_> archivist: for example TSPLIB has some pcb drilling files as test cases for TSP solving, like this: http://www.anderswallin.net/wp-content/uploads/2011/05/tsp.png
[11:56:22] <Loetmichel> jthornton: ahem... i beg to differ. dxf2gcode is not really useful
[11:56:36] <TekniQue> pcb-gcode also works well
[11:56:37] <archivist> because gerber never sees the drill file
[11:56:39] <Loetmichel> i use BoCNC. nbut that is windows
[11:56:43] <jthornton> why is that?
[11:56:47] <TekniQue> if you are an Eagle user
[11:57:10] <TekniQue> lets you export g-code for milling and drilling straight from Eagle

[11:57:45] <jthornton> Loetmichel: why is dxf2gcode not useful?
[11:57:47] <Loetmichel> has a mill-export (in gcode or HPGL ) also
[11:58:12] <Loetmichel> jthornton: for example: it cant change tools based on colour
[11:58:39] <jthornton> why would you want to do that?

[11:59:30] <Loetmichel> becvause you can export the Isolation and the driolls and the rubout and the outline all in one dxf
[11:59:43] <Loetmichel> ant make ONE gcode out of it
[11:59:59] <Loetmichel> <- sorts his fingers
[12:00:22] <archivist> awallin, I will try to dig out one of my old designs one day which has a serious amount of holes, has about 150-200 ics on it
[12:00:53] <jthornton> or just concatenate the three files after you generate them... but for my plasma cutter it will work great with a few modifications
[12:02:45] <Loetmichel> last PCB i did: http://www.cyrom.org/palbum/main.php?g2_itemId=11957
[12:03:04] <Loetmichel> 0,1mm isolation groove
[12:03:11] <Loetmichel> 0,3mm traces
[12:09:40] <TekniQue> Loetmichel: what is that for?

[12:26:55] <stillme> i noticed it just moves in z axis once to penetrate the material to be cut and after that it just stays on that level on z axis
[12:27:31] <Jymmm> Can you paste your gcode http://codepad.org
[12:28:59] <stillme> the gcode?? how do i get that out of emc/axis??
[12:29:55] <stillme> which compiler do i choose in codepad.org??
[12:29:58] <Jymmm> Did you save it to a file? It should just be able to open in a text editor.

[12:43:15] <archivist> there is a skill to it. gundrills have through tool coolant, most important use is swarf clearance from the hole, because its the swarf casing the drill to go off tru

[12:48:20] -!- nullie has quit [Quit: Ex-Chat]
[12:50:45] <The_Ball> Ah, is that the main reason normal drills sway?
[12:51:38] <The_Ball> That should have read: ah, so that's why normal drills sway
[12:52:11] <The_Ball> So being more careful with keeping the flutes clean a normal drill will drill more straight...
[12:56:26] <archivist> yes thats what peck drilling is about, getting the swarf clear
[12:56:54] <archivist> but the cutting edge has to be good

[13:03:48] <Jymmm> Z is moving, but it's very small. Are you sure it's not moving at all?
[13:04:58] <Jymmm> Maybe try it again now that you have saved the file. Even if just cutting air.
[13:05:34] <jdhNC> I'd try regenerating the gcode from the image with different z scaling?

[13:12:26] <jdhNC> G21
[13:12:41] <Jymmm> well, then I guess that explains it.
[13:14:09] <stillme> its in mm
[13:14:42] <stillme> the problem is that when i give it a 3mm thick work piece, it first cuts right through the material
[13:14:53] <stillme> so i wouldnt know if its actually moving or not

[13:22:53] <stillme> i just tried to cut a 3d object from a vectric software, and it just finished cutting it

[14:46:59] <cradek> yes that is gang tooling. easiest/fastest tool change ever.
[14:49:15] <JT-Shop> neat live tooling too
[14:49:51] <archivist> closest to a cam auto for speed, except the cam auto never had the milling and tapping (not seen one)

[14:54:50] <cradek> that machine would have xyz offsets I think?
[14:55:14] <archivist> depends which gang of tools
[14:56:01] <archivist> I can imagine it could turn either direction too
[14:56:30] <cradek> that's true
[14:56:50] <cradek> and reverse X, or maybe change so X is vertical
[14:59:24] <cradek> you could run it with manual (or cam) consideration of x/y/z/m3/m4 but it'd be nicer if it handled it
[15:00:16] <anonimasu> if I made that I'd make a offset macro
[15:00:28] <archivist> there are aspects of the double headed Citizen that beat it though

[15:44:13] <ssi> I have an MT2 and MT3 taper holder that goes on the front side of my QCTP, so they're parallel with spindle axis

[15:44:50] <cradek> I'd have one tool table entry for each holder, whether drilled MT or chuck

[15:46:15] <IchGuckLive> Hi all how about homing a Rotary C-Axis
[15:46:23] <ssi> lemme try to open up emc so I can find what you're talking about
[15:46:40] <IchGuckLive> can i then rotate beond the homiing point
[15:46:48] <cradek> IchGuckLive: servo/encoder or stepper? does it have a home switch?
[15:47:05] <IchGuckLive> stepper home switch
[15:47:16] <cradek> then you can home it like any other axis
[15:47:26] <cradek> do you have a more specific question?
[15:47:54] <IchGuckLive> but it will press the home switch on every rotation
[15:48:10] <cradek> that does not matter. home switches are ignored except when homing.
[15:48:19] <IchGuckLive> ah
[15:48:23] <IchGuckLive> ok
[15:48:50] <cradek> many (all?) axes push their home switches during normal use because the home switch is inside the travel limits
[15:48:51] <IchGuckLive> so on the 5 Axis i go for home switch 1 parport for all 5 Axis
[15:49:35] <ssi> aw crap, lathe machine is shut down at home :(
[15:49:44] <cradek> yes you can wire many home switches together and use just one input. you will have to home one at a time then.
[15:49:52] <IchGuckLive> on the 3 Axis i use linit min as the homing
[15:49:54] <cradek> see HOME_IS_SHARED in the docs

[16:23:48] <willburrrr2003> when using multiple home switches, if I home the x axis and leave it sitting at it's home point, then tell it to home m z axis...will it work with the x-axis sitton on home switch?
[16:25:05] <cradek> see HOME_IS_SHARED in the docs
[16:26:13] <skunkworks> willburrrr2003: homing doesn't 'sit' on the switch. it hits it - then backs off.

[16:27:37] <willburrrr2003> thx for the link
[16:29:52] <The_Ball> skunkworks, somebody mentioned you had an opinion on the minimum spindle encoder resolution one should have for rigid tapping, and that value was around 360, was that indeed your opinion and if so what is that based on?
[16:32:15] <Tom_itx> wasn,t me but i'd guess one tick per degree of revolution
[16:33:40] <The_Ball> that's the obvious link, but I was more interested in any reasoning behind it

[20:45:51] <Tom_itx> those look the same as sanvick relly
[20:45:54] <Tom_itx> really*
[20:46:54] <JT-Shop> I usually buy most of that kind of stuff from MSC cause it is easier... if I did more volume I'd have a tool monger come by the shop
[20:47:13] <Tom_itx> they're kinda nice sometimes
[20:47:31] <Tom_itx> they helped us get up to speed on titanium and tungsten
[20:50:18] <DaViruz> sanvick? you mean sandvik?
[20:50:27] <Tom_itx> yeah
[20:50:33] <DaViruz> (not trying to be an ass, just want to clarify)
[20:50:38] <DaViruz> ok
[20:50:46] <Tom_itx> been quite a while since i was there
[20:51:12] <Tom_itx> i had their insert catalog here somewhere
[20:51:59] <DaViruz> i live pretty near the city "sandviken" in sweden where they make them :)
[20:52:13] <Tom_itx> good stuff i think
[20:54:16] <DaViruz> a bit expensive but well worth it imo
