[01:01:48] <atom1> so at 2.2mH 46.9v would be max and at 8.8mH series it would be 93.8v according to that site
[01:07:35] -!- sumpfralle has quit [Ping timeout: 276 seconds]
[01:09:14] <Jymmm> atom1: Typically it's 20x the rated voltage
[01:09:23] <Jymmm> 20-25x
[01:09:53] -!- crazy_imp has quit [Ping timeout: 240 seconds]
[01:10:20] <atom1> 1.93 and 3.86 respectively
[01:10:47] <atom1> but using the inductance and jt's link i get the above numbers
[01:11:55] -!- crazy_imp [crazy_imp!~mj@a89-182-14-73.net-htp.de] has joined #emc
[01:12:03] <Jymmm> well 20x comes close
[01:12:31] <atom1> i'm putting together a 50v supply i got surplus here
[01:12:42] <atom1> no load i get ~50v
[01:12:42] <Jymmm> 50v ac?
[01:12:44] <atom1> no
[01:12:46] <atom1> dc
[01:13:00] <atom1> linear supply
[01:13:15] <Jymmm> 50v transformer?
[01:13:17] <atom1> xfmr with a bridge and a couple caps
[01:13:28] <atom1> i think the ac v is ~38v iirc
[01:13:31] <Jymmm> k
[01:13:35] <Jymmm> just checking =)
[01:13:38] <atom1> i'd have to check again
[01:13:47] <atom1> i know you gain about 1.7x
[01:13:50] <Jymmm> no, you said what I wanted to hear =)
[01:13:52] <atom1> or thereabouts
[01:13:57] <atom1> i know i did
[01:13:58] <atom1> :D
[01:14:01] <Jymmm> 1.707 iirc
[01:14:10] <Jymmm> or is it 1.414
[01:14:13] <Jymmm> somethign liek that
[01:14:21] <atom1> i was hoping these weren't too hot for the steppers
[01:14:31] <atom1> since they were cheap
[01:14:35] <Jymmm> doens't look like it
[01:14:44] <atom1> i may get another one
[01:14:52] <atom1> they're about 6A i think
[01:14:57] <Jymmm> I'd try one first
[01:15:43] <atom1> now to find some drivers that are happy with 50v
[01:15:53] <Jymmm> geckos
[01:15:56] <atom1> i know
[01:16:01] <atom1> i'm looking at them
[01:16:16] <atom1> I don't think their 4 stepper board takes 50v
[01:16:37] <Jymmm> sure it does
[01:17:00] <Jymmm> i think
[01:17:04] <atom1> the G540
[01:17:17] <Jymmm> OEM750 does 24-75VDC
[01:17:25] <Jymmm> 7.5A peak
[01:18:03] <Jymmm> # 18VDC to 50VDC supply voltage
[01:18:16] <atom1> that's pushing it
[01:18:16] -!- skunkworks has quit [Remote host closed the connection]
[01:19:02] <Jymmm> Well, OEM750
[01:22:44] <atom1> i don't see that one
[01:23:25] <Jymmm> http://www.compumotor.com/products/Stepper_Drives_and_Motors__4003__30_32_80_567_29.html
[01:26:02] <atom1> they're proud of their stuff
[01:26:34] <Jymmm> I got some off ebay pretty cheap
[01:26:53] <atom1> no problems with em?
[01:27:07] <Jymmm> no, you can ask ve7it too, he has a few
[01:27:14] <Jymmm> Lawernce
[01:30:04] <Jymmm> atom1: 50,000 steps per revolution =)
[01:32:27] <Jymmm> Just dont confuse OEM-750X - it has an added indexer board in it (user removable)
[01:32:50] <Jymmm> SPR == 200 - 50,000
[01:33:32] <atom1> my sherline wouldn't know how to act with stuff like that hooked to it
[01:33:48] <Jymmm> lol, well there's alway 200 spr

[11:46:37] <jthornton> I have a profile for my lathe. What is the easiest way to offset that profile multiple times so to cut say 0.025 deep on each pass?
[11:52:09] -!- stillme [stillme!~stiyke@] has joined #emc
[11:56:21] <archivist> have the profile code make sense in relative mode and a while loop in absolute moving it inwards
[11:57:00] <jthornton> would that work with tool radius comp?
[11:58:35] <archivist> one of us has to try it and see :)
[11:59:04] <jthornton> lol, yes
[11:59:44] <archivist> or just stay in one mode and add the offset constant to the profile points
[12:00:18] <stillme> doesn anyone know any ways of generating gcode from a picture?
[12:00:49] <stillme> i tried to use vectric Photovcarve but i dont see post processor for EMC2

[12:16:39] <stillme> archivist: yea i have seen that, but some what when i use emc2 embedded image to gcode, it machines so slow
[12:17:15] <stillme> when i use gcodes i saved from vectric software, it finishes the job faster
[12:18:34] <stillme> ohh i see, thanks archivist, i think i found where i could be doing it wrong

[12:29:51] <stillme> jthornton: no, but am reading it now
[12:56:01] <jthornton> hmmm, writing relative mode code is a bit of a pain

[14:25:42] <JT-Shop> are you watching the torch or the DRO?
[14:26:41] <anonimasu> watching the torch
[14:26:53] <anonimasu> I need to set up the vcp stuff so I can monitor it in cut
[14:28:53] <anonimasu> the arc-ok I have no real idea what to do with...
[14:36:30] <JT-Shop> ark-ok has to be on to allow correction
[14:36:56] <JT-Shop> if(torch_on && arc_ok && vel_status){ // allow correction

[19:16:19] <JT-Shop> now I just need a SIMPLE way to create a path from a dxf file...
[19:16:57] <jdhNC> cut2d is simple, but windows, and not free.
[19:17:26] <JT-Shop> I have OneCNC on my windows machine
[19:17:29] <Jymmm> ace converter?
[19:17:38] <JT-Shop> Jymmm: what is that?
[19:17:56] <Jymmm> http://www.dakeng.com/ace.html
[19:18:59] <sumpfralle> PyCAM (http://pycam.sf.net) is a 2D/3D toolpath generator - just use the "gravure" strategy for your 2D DXF file
[19:19:14] <sumpfralle> (GPL, for linux/mac/win)
[19:20:38] <JT-Shop> I've messed with PyCam a bit but could not get it to work
[19:21:56] <JT-Shop> I have my profile subroutine working now, feed it a proper subroutine of the profile and it will rough it out then do a finish pass
[19:24:23] <sumpfralle> @Jymmm: if you run into problems with PyCAM: just ask me (I am one of the developers)
[19:24:59] <sumpfralle> (misdirected - sorry)
[19:25:20] <Jymmm> sumpfralle: Can it SLICE STL files?
[19:27:53] <sumpfralle> it can project a 3D model to 2D at any given height - is that enough?
[19:28:48] <Jymmm> What I really need is to be able to slice STL file into multiple SVG (or other vector) files (one per layer)
[19:30:07] <Jymmm> or multiple sliced objects in a single vector file
[19:31:18] <andypugh> I just put a mini-PCI wifi card in my CNC machine, and it seems to prevent it booting. Is that normal?
[19:31:50] <Jymmm> check the bios?
[19:31:54] <andypugh> (It's one from a Dell laptop)
[19:32:14] <andypugh> What should I check in the BIOS?
[19:32:30] <Jymmm> I dont know, boot sequence?
[19:32:45] <andypugh> Would it try to boot from a PCI card?
[19:32:50] <Jymmm> or is it stoppong ubunyu from booting?
[19:33:10] <andypugh> It's stopping the BIOS from booting.
[19:33:11] <Jymmm> or is it stopping ubuntu from booting?
[19:33:35] <Jymmm> Then, check the BIOS =) Make sure you have it seated correctly too
[19:34:15] <sumpfralle> @Jymm: you can do multiple slices step-by-step (from STL to SVG). Hope this helps.
[19:34:50] <Jymmm> sumpfralle: multiple slices per svg file?
[19:36:07] <Jymmm> or slice1 == 1.svg, slice2 == 2.svg, etc ???
[19:36:43] <sumpfralle> partly: you could join these via Inkscape (copy/paste with the clipboard). Even multiple levels are supported (using different colors), but SVG is not made for 3D modelling, thus using more than two different colors (=levels) gets complicated.
[19:38:28] <Jymmm> sumpfralle: I need to take a 3D Model (stl), slice it to 1/8" thick slices, then end up with a SVG file that has mutiple slices for cutting with a laser.
[19:41:10] <sumpfralle> Jymmm: do you plan to put the different shapes into different SVG layers? Or how else are they distinguished by your software?
[19:42:28] <fragalot> Well that didn't go well
[19:42:42] <fragalot> the plastic I got mills REALLY REALLY well.. a bit too well
[19:42:44] <atom1> you were dancing earlier
[19:43:02] <fragalot> sucked my tool in like nothing i've seen before
[19:43:25] <fragalot> there are grooves from my chuck that almost match the spiral on the flanges of the mill bit
[19:43:56] <Jymmm> sumpfralle: If you took a simple drinking cup, ran it through a bread slicer, you would end up with multiple 1/8" thick pieces. It's those pieces that I need in vector (svg) format. Best of each slice is in the same file then can be nested nicely on to a single sheet of material to be cut out.
[19:43:59] <atom1> so it wasn't tight
[19:44:18] <fragalot> atom1: it was as tight as I could get it on that small thing
[19:44:21] <fragalot> and the grooves are rather deep
[19:44:38] <fragalot> I tried drilling into the material w/ a hand drill and my god does it pull
[19:45:24] <andypugh> Jymmm: I have some Octave code that will slice an STL file into EPS, if that is any good?
[19:45:26] <fragalot> Anyway enough for today i'll see if I can do the rest tomorrow..
[19:46:03] <fragalot> I've noticed my Z axis flexes along the Y axis when it pushes down.. (1mm!)
[19:46:31] <fragalot> need to figure out if I can stop it from doing that asap :/ There isn't enough time in a day! :'(
[19:48:21] <sumpfralle> Jymm: I am still not sure, how you combine these 2D shapes in a single SVG file. Do you just put all of them into a single layer?
[19:48:34] <Jymmm> sumpfralle: correct
[19:49:03] <fragalot> Jymmm: don't answer an "or" question with yes/correct please
[19:49:07] <fragalot> it confuses everyone :p
[19:49:50] <sumpfralle> Jymmm: then you would just need to copy/paste the 2D shapes into Inkscape after each slicing.
[19:50:32] <andypugh> Jymmm? Interested?
[19:50:39] <sumpfralle> andypugh: if Octave can do this via the commandline, then I guess, this would be a good option for Jymmm. The result can be combined with Inkscape later.
[19:51:01] <andypugh> http://pastebin.com/uvCiibHB
[19:51:15] <Jymmm> If there are 200 slices, I'm sure in the hell not going to copy-n-paste 200 times =)
[19:52:16] <andypugh> It was code I wrote for one job, once, so isn't very polished. I think that the line near the top "f=0" needs to be made into an f=fileopen() as it looks like this version doesn't actually create the EPD
[19:52:20] <andypugh> (EPS)
[19:52:30] <Jymmm> http://www.evilmadscientist.com/article.php/slicingstl
[19:52:46] <Jymmm> andypugh: I have no idea what octavia is
[19:52:56] <andypugh> It's a gnu version of Matlab
[19:53:07] <Jymmm> oh, ew
[19:53:58] <andypugh> It's perfect for that kind of work. See how compact that code is (the bit that turns the triangles into continuous line segments)
[19:54:35] -!- mhaberler [mhaberler!~mhaberler@extern-182.stiwoll.mah.priv.at] has joined #emc
[19:55:46] <Jymmm> andypugh: Does it put each slice as an object in a single .eps file?
[19:58:10] <Jymmm> or multiples .eps files when you run out of sheet space
[20:01:32] <andypugh> It moves onto the next sheet when the sheet is full.
[20:02:33] <andypugh> The version I have pasted actually drives a plotter using HPGL. I could probably make you a working EPS-only version
[20:03:09] <Jymmm> cool, Ok, so what's the out HPGL or EPS ?
[20:03:17] <Jymmm> cool, Ok, so what's the output, HPGL or EPS ?
[20:03:30] <Jymmm> PS would work too =)
[20:03:43] <andypugh> That version shoves HPGL out of the serial port. But the EPS code is still in there.
[20:04:02] <Jymmm> Ah, ok. I was wondering why there was mention of HPGL
[20:05:00] <Jymmm> Leave it as is for now. I'm not sure when I'll get a chance to play with it.
[20:05:03] <andypugh> I used that code to make these out of sticky paper. https://picasaweb.google.com/bodgesoc/Gibbs#5478341215134773746
[20:05:35] <andypugh> (sticker paper and a drag knife on a flatbed plotter)
[20:05:52] <andypugh> Then sent them off to the brassfounders as a pattern.
[20:06:01] <Jymmm> heh
[20:06:06] <Jymmm> bbiab
[20:19:50] <ve7it> Jymmm, http://www.freesteel.co.uk/wpblog/slicer/
[20:36:01] <Jymmm> ve7it: I think I actually have that bookmarked.
[20:36:28] <Jymmm> ve7it: atom1 was askingng if OEM750's were any good
[20:36:53] <atom1> i don't doubt they're good
[20:37:25] <atom1> what makes a driver good? the higher frequency step rates?
[20:37:51] <Jymmm> not necessarily.
[20:38:12] <Jymmm> I mentioned the oem750 becasue you wanted higher voltages
[20:38:41] <atom1> well it would probably work better with higher voltages within reason
[20:38:49] <atom1> i think my supply is within reason
[20:39:00] <atom1> but maybe at the upper limit
[20:39:31] <atom1> for the steppers i have
[20:40:13] <atom1> i can always use the original supply (24v i think)
[20:42:39] <atom1> do any mills you know of use left hand threaded screws?
[20:42:46] <atom1> this silly sherline does
[20:43:14] <cradek> many manual machines have LH screws to make the handles turn the right way
[20:43:21] <andypugh> Lathe leadscrews are normally lef-hand.
[20:43:28] <cradek> it depends which part moves and which is stationary
[20:43:31] <atom1> yeah
[20:43:34] <atom1> makes sense
[20:43:41] <andypugh> (on the cross-slide at least)
[20:44:06] <atom1> so a lefthand ballscrew wouldn't be that uncommon
[20:44:22] <andypugh> I have never seen one.
[20:44:26] <atom1> heh
[20:44:27] <cradek> if the handle moves with the moving part, the screw is RH -- if the handle doesn't move, the screw is LH
[20:44:51] <cradek> a sherline manual mill table probably has one of each
[20:45:00] <atom1> the z is
[20:45:13] <atom1> i didn't check the others yet
[20:45:15] <cradek> I'd guess X rh, YZ lh
[20:45:49] <cradek> ballscrews are never (?) on manual machines so a LH ballscrew is not ever (?) necessary
[20:45:53] <atom1> 3/8 20 left hand
[20:46:02] <atom1> that would be an impossible tap to find
[20:46:14] <andypugh> No reason to keep the handedness when converting though. My lathe has a wrong-way handle in manual mode, but I very rarely use it that way.
[20:46:29] <atom1> well, i never have on the mill
[20:46:56] <andypugh> cradek: TOS clones of the Thiel clone of the Deckel frequently have ballscrews.
[20:47:02] <atom1> i would like to add a jog wheel though for sure
