[00:03:09] <Jymmm> JT-Shop: I've lazy, I don't peel the potatoes =)
[00:04:52] <Jymmm> JT-Shop: Besides, you're hand will be sore just after cutting 7-12 potatoes that thin

[07:54:52] <pingufan> Hello, somebody herewho can show me an example code, please? I want to do manual tool change in a CNC mill. For that, the mill must do the following steps: 1. Lift tool to maximum height (Z), then move to the front (Y=0). NowI can replace the tool. Then I want to adjust the Z-height to a known height (I put a block of knownheight onto the machine desk and touch it). Then the program shall continue.
[07:56:31] <pingufan> o the Z-Axis might change, bit X ynd Y must be kept during a tool change. Of course, the mill must then first lift up to maximum "Z", then return to previous X and Y, and then descend the tool with running spindle.
[07:56:53] <pingufan> I find no example for that.
[08:21:14] <mhaberler> http://www.mail-archive.com/emc-users@lists.sourceforge.net/msg17879.html
[08:26:42] <pingufan> Thank you. Will this also work with an older version of EMC, or only the newest one? My computer uses a VIA EPIA M10000 mainboard with VIA C3 CPU and newest EMC2 does not run on it.
[08:27:11] <mhaberler> should run on any washer and dryer
[08:30:35] <pingufan> Can you recommend me a real beginners guide for EMC2? What I find at linuxcnc, is more or less a list of possible commands with brief explanation, but this is not what I really need. I'm looking for a real tutorial, teaching me how to operate and use emc2.
[08:31:27] <pingufan> I am a total novice, at school (>35 yrs ago) we were proud to mill a rectangle!
[08:32:05] <pingufan> Since that time I never used G-Codes, so you can imagine how I feel.
[08:32:51] <pingufan> I need something that really guides me.
[08:32:59] <Jymmm> http://www.linuxcnc.org/docview/html/
[08:35:49] <pingufan> Jymmm: This is what I not meant...

[08:37:32] <pingufan> :/
[08:43:09] <pingufan> For a little milling project I borrowed a CNC mill from a friend. The software was Windows based and was able to import AutoCAD plot files directly. (I used it to mill openings into plastic enclosures, cut pcb's, etc.) Was relatively easy to handle, I could use it within 15 minutes. Later I bought a damaged engraving machine (burned electronics) for low money. Meanwhile it is working except that I need a precise spindle and a machine desk. In
[08:43:11] <pingufan> fact, I will only need 2 1/2 D most of the time, but I never got in touch with G-Codes so directly.
[08:43:23] <mhaberler> Then do so now.
[08:44:21] <pingufan> And fr that I need a good tutorial, no list of G codes. I have to learn it from scratch, but this is hard when I have no guide.
[08:45:19] <pingufan> Something that presumes that AXIS is correctly configured and only _teaching_ in small steps how t use it now.
[08:46:54] <pingufan> All this descriptions I find in linuxcnc presume too much.
[08:54:54] <Connor> Can someone take a look at these and tell me why the funky diagonal line is in my pocket in the lower right hand area? http://www.ivdc.com/cnc/PCB-Jig
[08:55:52] <pingufan> As an example: I mount a wooden workpiece holder onto the machine desk. X-Axis is left-right, Y-Axis is front-rear, Z-Axis is up-down. On this workpiece holder/adapter I have a point/marker which is the origin for all work on the workpiece. I manually move the toolabove it and descend the tool tip until a very thin plastic film is slightly clamped.This shall be 0/0/0 for the workpiece. -> What must I do to get that done with AXIS?
[08:56:38] <Jymmm> Connor: Those are toolmarks. Looks as if either the workpiece or the gantry is not level.
[08:57:14] <Connor> Why does it look okay on all the other parts?
[08:57:20] <Connor> be back in a few..
[09:00:45] <Tiffany> okay, on a diff computer.
[09:00:52] <Tiffany> Tiffany is now known as Connor_
[09:02:42] <pingufan> Can somebody, please, explain me the steps to what I asked?
[09:06:49] <Connor_> it not being perfectly level was the reason for this jig and pocket....
[10:11:23] <pingufan> Hello, I have to mill holes into a plastic enclosure. Because the cutter is very thin, I cannot mill the whole depth at once. Can emc automatically repeat a path and hereby go deeper every time by itself, or must I code that manually
[10:11:27] <pingufan> ?
[10:19:14] <awallin> you could code it with a sub-function
[10:19:20] <awallin> see O-words in the wiki
[10:20:04] <pingufan> Thank you.
[10:20:47] <pingufan> Do youhave a really good PDF book for bloody beginners?
[10:23:54] <awallin> try smid (peter?) on amazon and/or piratebay...
[10:26:32] <pingufan> Can you tell me the title ?
[10:35:22] <dimas_> pingufan, why don't you use cam software?
[10:36:16] <dimas_> i'm a beginner too, btw
[10:36:38] <pingufan> I have none.
[10:36:57] <pingufan> I am working on Linux only, btw.
[10:37:09] <dimas_> me too
[10:37:39] <dimas_> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?cam
[10:39:36] <pingufan> Well, it is a little bit problematic at all... I am familiar with AutoCAD, but there is none for Linux. Only this (much weaker) qcad.
[10:40:22] <pingufan> And for that what I wantto do I do not buy software. ;)
[10:41:06] <dimas_> but emc could not substitute cad nor cam software
[10:42:02] <dimas_> and i do not expect emc's documentation for that
[10:42:17] <pingufan> Sure. And in addition, CAD is not able to visualize all necessary things for CNC...
[10:43:03] <dimas_> i was succesfully took sd model from reprap project in stl
[10:43:40] <pingufan> Yes, EMC's documentation appears to me as a better list of commands. This might be sufficient for people familiar with EMC, but I am a beginner...
[10:43:58] <dimas_> then got dxf 2d outline which was accepted by qcad and others
[10:44:27] <dimas_> then in heehscnc did contour and pocketing operations
[10:44:53] <dimas_> and gcode and then milled on diy router
[10:45:15] <dimas_> all on linux
[10:45:25] <dimas_> no commercial software
[10:45:27] <pingufan> Most of the time I will need only 2.5d (milling cutouts into enclosures)
[10:45:43] <pingufan> What you do is approx. the same what I want to do...
[10:46:14] <dimas_> test different cam software options
[10:46:59] <pingufan> Do you know something that is similar to AutoCAD?
[10:49:01] <pingufan> Ha, this TurboCNC mentioned so often in GCAM -- I bought a license of it some years ago for Linux. Such a crap I never saw before in my life. Claims to be "Autocad", but most behaviour is totally different. :(
[10:50:56] <dimas_> I did not use Autocad recently so hard to compare, I was able to do simple things in qcad when needed
[10:51:33] <pingufan> Must have a closer look on Qcad again...
[10:52:02] <pingufan> How is your workflow?
[10:53:45] <dimas_> workflow?
[10:54:46] <pingufan> From drawing to milling. Which programs do you use?
[10:55:01] <pingufan> And how?
[10:57:16] <dimas_> pingufan, i'm in the beginning really
[10:57:37] <pingufan> And how do you plan to do?
[10:57:58] <dimas_> heekscad/heekscnc as I said above
[10:58:39] <dimas_> tested Openscad for coding 3d models
[10:58:45] <dimas_> tested Freecad
[10:59:18] <pingufan> is heekscad free?
[10:59:33] <dimas_> looked on gcodetools - it's a cam plugin for inkscape
[10:59:38] <dimas_> pingufan, yep
[11:00:54] <dimas_> tried pycam - it was too slow
[11:01:24] <pingufan> Where I have some difficulties is with direktion of lines/polygons... It is possible to do a tool-radius compensation. But when I do no know in which direction it moves... :/
[11:01:41] <dimas_> heekscnc do that
[11:02:10] <pingufan> Oh, was told that lunch is ready. Are you here in 1/2 hour?
[11:02:17] <dimas_> radius compensation
[11:02:23] <dimas_> should be
[11:02:43] <pingufan> Thanks.
[11:04:54] <dimas_> profile operation in heekscnc has selection for cut mode - conventional/climb
[11:09:20] <dimas_> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?InkscapeHowto
[11:24:50] <pingufan> dimas_: I am back again.
[11:25:04] <dimas_> ok :)
[11:27:26] <pingufan> So when I understand right, heekscad is a CAD program and heekscnc re-uses heekscad's files to convert them into G-codes?
[11:30:05] <dimas_> yes
[11:30:19] <dimas_> heekscnc works inside heekscad
[11:30:21] <pingufan> Whow, heekscnc even offers SuSE rpms! :)
[11:30:39] <dimas_> you on Suse?
[11:31:05] <pingufan> Almost only. Actually I hate ubuntu, but with emc2 I have no real choice.
[11:31:48] <dimas_> there are debs for ubuntu
[11:32:08] <pingufan> (Except I accept to compile everything by myself ...)
[11:33:14] <dimas_> i was able to compile heekscad/cnc but got something broken with latest updates
[11:33:42] <pingufan> I watch now this link http://code.google.com/p/heekscnc/ but cannot really see where a track starts and in which direction it goes. Can I see that somewhere?
[11:34:58] <dimas_> https://m21.hyte.de/downloads/heekscad/ubuntu_10.04_2010-09-11/ - packages for ubuntu
[11:35:40] <pingufan> And for SuSE?
[11:36:05] <dimas_> I do not know
[11:36:09] <pingufan> :D
[11:36:32] <dimas_> http://code.google.com/p/heekscad/source/checkout - sources as usual on google code
[11:36:41] <pingufan> The only Ubuntu is on the mill itself. Everything else is SuSE at me.
[11:37:11] <dimas_> http://code.google.com/p/heekscnc/w/list - useful wiki pages
[11:37:49] <pingufan> But heekscad looks very good. :) Thank you for this hint!
[11:38:47] <pingufan> So I must intall first heekscad then then heekscnc, and after that heekscad can do all that together?
[11:40:32] <dimas_> pingufan, hope it does :)
[11:41:36] <pingufan> I'll have a look if openSuSE has that in its repositories...
[11:43:42] <pingufan> Hmm - not directly in SuSE repositories...
[11:44:21] <pingufan> Hope there are at least ready binaries for it, I don't prefer to compile myself...
[11:45:55] <pingufan> Interesting that when I go to downloads I only see .exe files. ?!
[11:50:20] <dimas_> http://software.opensuse.org/search?baseproject=ALL&p=1&q=HeeksCAD
[11:53:13] <pingufan> Oh, thank you! Is heeks-cad really below version 1.0 ?
[11:55:51] <dimas_> I think so
[11:56:20] <pingufan> This 1-click install of SuSE is really perfect. I love it. :)
[11:57:51] <pingufan> Installing now...
[11:59:10] <mhaberler> is there a #5xxx parameter(s) which returns the current *absolute* machine position?
[12:07:03] <pingufan> where does heekscad usually install?
[12:08:05] <mhaberler> There is a heekscad channel on freenode for this program, this might help you with heekscad related questions
[12:08:07] <mhaberler> and there is a website for heekscad
[12:08:23] <pingufan> Ok. Thank you.
[12:14:26] <dimas_> pingufan, rpm -ql <packagename> should give you file list
[12:14:37] <dimas_> if I recall correctly
[12:15:23] <pingufan> Got it meanwhile. That the Program name starts wit uppercase, is a little bit unusual...
[12:15:55] <pingufan> dimas_: can we go private, please?
[12:16:35] <pingufan> Don't want to flood this channel with out of topic things.
[12:18:35] <dimas_> it is silently here anyway and we can go to #cam
[12:34:23] <jthornton> mhaberler: I don't see one
[12:34:39] <mhaberler> me neither
[12:34:56] <jthornton> I wonder where Axis gets the info?
[12:35:24] <mhaberler> I want to do something trivial
[12:35:26] <mhaberler> halui.axis.0.pos-feedback is an option
[12:38:41] <jthornton> or axis.0.join-pos-cmd
[12:40:38] <mhaberler> the point is simply: build a probing ngc sub which returns exactly to the starting point in both success and failure cases - looks undoable in the succes case because I dont see a way to get at the starting point; except for some fiddling with coordinate systems
[12:43:04] <jthornton> the starting point of the probe tripping?
[12:46:45] <mhaberler> the start of the probe run
[12:46:47] <mhaberler> #506x has the trip point, but how do you return to start (not roughly.. exactly!)
[12:47:17] <mhaberler> of course I could back off but I want to have it serially repeatable with no shifts
[13:06:11] <jthornton> I'm sure I don't understand what your trying to do now :) if the start point is a variable then you can go exactly back to that
[13:10:01] <mhaberler> it is the current position, wherever that happens to be
[13:11:04] <mhaberler> it's always possible with passing in the current position by my tacit assumption was the g-code interpreter can determine the absolute external position to use it in expressions
[13:11:20] <jthornton> so your wanting to jog over to a point then probe?
[13:12:46] <mhaberler> I want to start the probe sub at the current point, and want the tool in that point when it finishes, whatever happens (success or failureI
[13:18:04] <robh__> can you not read G53 parameter from gcode file and store it use it as the return point when running the sub
[13:18:31] <jthornton> morning robh__
[13:18:49] <robh__> hi
[13:18:49] <the_wench> hello robh__, you have a question?
[13:19:01] <robh__> was ref to mhaberler
[13:20:29] <mhaberler> re G43 paramter: yes, I'd love to read it. The question is: from where
[13:20:30] <mhaberler> I am NOT referring to hardcoded positions, or 'lets back off a bit"
[13:20:37] <mhaberler> G43/G53
[13:22:18] <mhaberler> It's an obvious omission and trivial to add to rs274, the question is wether I get the patch nodded of
[13:22:19] <mhaberler> and its clear why this surfaces now: G-code subs are beoming useful since probing works in subs
[14:51:56] <Jymmm> jthornton: How was your xmas PB&J sandwich?
[15:10:32] <JT-Shop> Jymmm: it was real good
[15:10:50] <Jymmm> jthornton: glad to hear it =)
[15:51:18] <jthornton> Jymmm: how was your potatoes r rotten?
[15:52:22] <Jymmm> jthornton: Good. I tried experimenting with the recipe by adding bacon and bisquick, but the bacon didn't add anythign to the dish, and the bisuick absorbed way too much liquid
[15:52:48] <jthornton> ok, I won't go there then
[15:53:07] <Jymmm> jthornton: So, in essense, I got it right the first tme and shouldn't have messed around with it =)
[15:57:41] <Jymmm> jthornton: Theres just so much oil and salt in the cheese, that it adds all the flavor needed.
[15:57:54] <Jymmm> gracefully that is
[15:58:32] <Jymmm> jthornton: But do use half and half if you can, makes it that much richer.
[15:58:46] <elmo40> once you add flour (bisquick) you need to add more liquids. that should be a given. egg, oil, milk... whatever else is in the recipe you need to increase.
[15:59:35] <Jymmm> elmo40: Nah, it has a lot of liquid, I was trying to suspend the liquid and it backfired is all.
[16:00:04] <Jymmm> I used very little bisquick
[16:00:07] <elmo40> the joys of cooking. you can experiment and 9/10 you will still eat it :P
[16:00:46] <Jymmm> only had milk this time too, so going back to half and half instead.
[16:00:56] <jthornton> Jymmm: do you have a photo of it for the recipe database?
[16:01:27] <Jymmm> jthornton: Sorry, no.
[16:29:17] <JT-Shop> do you guys just use an engraving bit to carve out a pcb?
[16:30:00] <Jymmm> jthornton: hang on
[16:32:27] <nullie> what bit do you use to cut sheet of metal?
[16:34:00] <JT-Shop> plasma
[16:34:16] <SWPLinux> LCD
[16:34:34] <nullie> well, in that case we use photoprocess to carve out a pcb
[16:34:45] <nullie> I mean if I only have cnc router
[16:37:39] <Jymmm> jthornton: I think this is what cradek uses http://www.precisebits.com/
[16:38:26] <Jymmm> jthornton: more specifically http://www.precisebits.com/applications/pcbtools.htm
[16:40:29] <JT-Shop> Jymmm: thanks
[16:41:05] <Jymmm> jthornton: np, I *think* some area using the "Trace Isolation Tooling" in the top right corner, but I'm not sure on that.
[16:41:14] <JT-Shop> ok
[18:10:40] <JT-Shop> it doesn't seem to matter how deep you cut a 1/4-16 thread a 1/4-20 nut will never thread on :/
[18:11:51] <pcw_home> Well maybe a little bit...
[18:28:49] <JT-Shop> about a half of a thread I think
[18:29:08] <leo> can't cut the nut 16 pitch?
[18:43:18] <JT-Shop> I believe I found the 0.039" thread wire that I dropped into the chip pit on the lathe
[18:57:30] <leo> jt - what do you have for your input - ext-fork0 to ext-fork 3 on the mpg?
[18:57:59] <leo> what is that section doing?
[19:03:28] <Connor> okay, so, can someone explain to me the tool marks on this.. http://www.ivdc.com/cnc/PCB-Jig
[19:04:00] <JT-Shop> leo: that is a bcd switch for feed override
[19:05:14] <awallin> Connor: you mean the diagonal line from the bottom-left corner?
[19:05:56] <Connor> Yea. and the more pronounced one in the lower right hand side.
[19:06:04] <Connor> the top side doesn't have ANY tool marks.
[19:06:57] <awallin> do you have max acceleration and feed set up right for the machine? (i.e. could it be missing steps, if it's a stepper machine)
[19:07:04] <awallin> or is the tool/spindle flexing?
[19:07:26] <Connor> It's not missing any steps..
[19:07:59] <Connor> and, my dust shoe is on springs.. so I don't think it's that causing it.. might be due to flexing.. not sure..
[19:08:08] <leo> jt - I assume there is one on the pendent with 4 positions and one on the display with 16 positions, is that correct?
[19:08:34] <Connor> I guess when it changes from front-to-back movement it could be flexing out a little maybe ?
[19:08:51] <awallin> Connor: you could try running a rough-pass first, and then leaving just a little cut for the finish pass, maybe 0.1 or 0.2mm, that should minimize flex on the final pass
[19:08:57] <Connor> not the tool, maybe the entire Z axis?
[19:09:28] <Connor> I did. The finial pass was like 0.00136"
[19:11:25] <awallin> you could play with G64PXX setting also...
[19:11:49] <Connor> what is that ?
[19:11:56] <awallin> blending of moves
[19:12:13] <awallin> but in your case the corners are 90-degrees, so I think no blending will occur anyway
[19:12:38] <awallin> with some g-code the blending might cause a smoother cut, and at least then the flexing would stay more constant, maybe...
[19:17:52] <JT-Shop> leo: no pendent but I do have a sub panel with a few buttons on it and the feed override knob and the mpg
[19:18:20] <JT-Shop> the FO is 12 positions I think
[19:27:04] <leo> addf scale.0 servo-thread gives me error 'scale.0' not found
[19:27:20] <psha> it's not scale.0 i guess
[19:27:30] <psha> something like scale.0.update or similar
[19:27:57] <leo> #spindle scales
[19:27:57] <leo> addf scale.0 servo-thread
[19:27:57] <leo> addf scale.1 servo-thread
[19:28:03] <leo> its scale.o
[19:28:13] <leo> copied from jt-shop's spindle section
[19:28:39] <psha> have you 'loadrt scale count=2' somewhere before that?
[19:29:10] <psha> it's really 'scale.0', without any function name
[19:34:02] <leo> it does not like your loadrt scale count=x no matter what number i insert
[19:36:57] <psha> how it's complaining?
[19:40:50] <JT-Shop> leo: your loadrt scale count=2 must be before the addf part
[21:31:36] <leo> pin mult2.0Ino does not exist -
[21:31:47] <leo> # spindle speed
[21:31:47] <leo> net spindle-velocity mult2.0.in0
[21:31:47] <leo> setp mult2.0.in1 60
[21:31:47] <leo> net spindle-abs abs.2.in mult2.0.out
[21:31:47] <leo> net spindle-rpm abs.2.out
[21:32:19] <leo> in your file what was mult2.0 in0?
[21:39:47] <leo> it looking for a pin named spindle-velocity or a pin named mult 2.0.in0?
[21:43:36] <leo> it loads everything except the spindle speed section and spindle at speed section
[21:50:45] <skunkworks> you need a mult2 loaded - there should be a loadrt mult2 http://linuxcnc.org/docs/2.4/html/man/man9/mult2.9.html
[21:51:13] <skunkworks> it also need to be added to a thread
[21:52:29] <skunkworks> like addf mult2.0 servo-thread
[21:57:38] <leo> how about near.2 - same kinda deal?
[21:58:28] <awallin> all components need to be loaded with loadrt, added to a thread, and then hooked up with net
[21:59:27] <leo> i found the loadrt for the mult, what am I looking for for the near?
[22:01:00] <awallin> if you are putting this together yourself then "loadrt near count=1"
[22:01:04] <awallin> or something similar
[22:01:15] <awallin> then addf near.0 my-thread
[22:15:49] <leo> going through adding the loadrt's working except for the mux16
[22:15:56] <leo> says it can't find it
[22:16:18] <leo> its not liking loadrt time wither
[22:17:16] <awallin> for mux16 you need emc 2.4.x
[22:17:31] <leo> running 2.4.6
[22:17:43] <awallin> actually you might need a git checkout...
[22:17:46] <leo> latest version
[22:17:52] <leo> a what?
[22:18:03] <awallin> 2.5.0-pre
[22:18:47] <awallin> oh, no, nevermind, mux16 is in 2.4
[22:19:15] <awallin> time might be only in 2.5
[22:19:42] <awallin> you might also get errors if you are trying to load the same components in many places. there needs to be only one line of HAL-code loading a single type of component
[22:19:53] <awallin> I think...
[22:23:21] <leo> copy from jt-shop- putting the loadrt's and most addf's in main halfile
[22:23:38] <leo> I don't know what version he is running on his hardinge
[22:24:01] <leo> emc loads now but no pwmgen command
[22:24:41] <awallin> ?
[22:25:04] <leo> tell it s1000 m3 and no motor movement
[22:25:14] <leo> no command but spindle on is made
[22:25:28] <awallin> put a hal-meter on motion.spindle-speed-out
[22:27:52] <leo> i think it may be simpler - need to understand "dac scale" better, should it be a number thats your max commandrpm or a number thats volts per rev/min?
[22:29:06] <awallin> not sure, but make sure you have everything hooked up right first... halmeter on spindle-speed-out, halmeter on encoder counts/velocity (spin spindle by hand to check it works), go from there
[22:29:16] <leo> http://pastebin.ca/2030114
[22:29:29] <leo> the gs5.hal - all spindle control and hookups
[22:33:22] <awallin> what does spindle-speed-DAC read when you say s1000 ?
[22:36:30] <leo> i don't see a spindle speed dac signal
[22:36:45] <leo> but pwmgen.03.value is 1.0001
[22:37:27] <awallin> that sounds like s1000 times scale.0.gain=0.001
[22:37:39] <awallin> rounded to a pwm compatible value
[22:38:01] <leo> but playing around without feedback if I put the pwmgen scale out as rpm it worked
[22:38:05] <awallin> can you put a real scope or multimeter on the dac output to see if it reads 1V ?
[22:38:24] <leo> pwmgen.03. value = 1000 was close to 1000 scaling it different
[22:39:13] <leo> it does not
[22:39:28] <leo> reads 0.007v or close
[22:39:39] <leo> don't totally trust that multimer that low
[22:40:10] <awallin> pwmgen.03.enable ? halmeter on that?
[22:40:21] <leo> live
[22:40:29] <leo> in watch hal
[22:40:55] <awallin> pwmgen.03.pwm_frequency ? something reasonable?
[22:41:09] <leo> talk to me about the scale, should it be in volts or rpm for the output?
[22:41:27] <awallin> duty cycle goes from -1 to 1
[22:41:38] <awallin> the duty cycle of the pwmgen is calculated as input/scale
[22:41:47] <awallin> err value/scale
[22:42:04] <jay_> jay_ is now known as fjay
[22:42:19] <leo> and the duty cycle is where?
[22:42:24] <awallin> that -1 to +1 is then converted to whatever your dac-output voltage is, maybe -10V to +10V
[22:42:49] <awallin> the duty-cycle is just an internal number in the pwmgen, you could measure it with a real scope, looking at the pwm
[22:43:50] <awallin> what do you have after your mesa-card? some interface and then a VFD ?
[22:46:17] <awallin> we are talkin this kind of big-iron?? nice. http://www.doughtysteel.com/Cinncinitti%20Saber%201250%20for%20sale%20001.jpg
[22:47:21] <leo> i have 2 1250's and a 1500
[22:47:42] <leo> the 2100 are great when they run - siemens pricing you inot a retro on parts
[22:48:22] <leo> the mesa 5120 x 2 - 7133ta x 2( 1 each 5i20), 4 x 7i37ta,
[22:48:37] <leo> going to a pico resolver to quadrature board
[22:49:00] <leo> then trying to use a gs3 durapulse in place of the kollmorgen vfs5 that was originally there
[22:49:07] <leo> as the vfs5 is f'd up
[22:49:23] <leo> have 1 1250 stripped to keep the rest operational
[22:49:43] <leo> and on bench to get basics of emmc running before cutting up broadway
[22:50:03] <awallin> I would disconnect the vfd for now, and see that you get a nice controlled -10V to +10V voltage swing from your 7i33 in a controlled manner that you understand...
[22:50:56] <leo> where you at awallin?
[22:51:07] <awallin> finland...
[22:51:29] <leo> thought u were europe from posts i have seen various places, iowa usa here
[22:52:18] <awallin> this is just outside my door a few days back: http://www.anderswallin.net/wp-content/uploads/2010/12/08122010606-1.jpg
[22:52:26] <awallin> got any snow over there ?
[22:52:38] <leo> about 6 inches fresh snow last 3 days
[22:53:38] <leo> unseasonably cold december so far... been in the teens on average
[22:53:54] <leo> usually low 30's average, thats degrees F
[23:35:25] <JT-Shop> leo: you get your spindle going?
