[00:00:24] <JT-Shop> kirk_wallace: if your still about ^^
[00:01:26] <kirk_wallace> Hello
[00:01:26] <the_wench> hello kirk_wallace, you have a question?
[00:02:58] <JT-Shop> darn it is too dark outside to hang trusses and I'm ready
[00:03:35] <kirk_wallace> JT-Shop: I'll look userinit over, thanks.

[00:07:00] <Guest334> anyone able to answer a basic question on EMC for me?
[00:07:17] <kirk_wallace> No, they are sitting against the wall next to the machine.
[00:07:21] <atmega> you are more likely to get a useful answer if you ask the question.
[00:07:25] <Guest334> fair enough
[00:07:53] <Guest334> I'm trying to open a gcode file within EMC and it does nothing. It won't open any file other than the EMC sample image that came with the program
[00:07:55] <Emcrules_Laptop> Kirk: i bought the same set and had a totaly different experience
[00:07:56] <Guest334> any ideas?
[00:08:14] <atmega> what happens when you try?
[00:08:17] <Paragon39> Check permission of files
[00:08:17] <Guest334> nothing
[00:08:26] <JT-Shop> ask
[00:08:27] <the_wench> Don't ask to ask, Don't state: "I have a question", Don't ask: "Is anyone around?" or "Can anyone help?". Just Ask The Question. Also, please read: http://workaround.org/getting-help-on-irc
[00:08:31] <Guest334> they are read only for everyone
[00:08:51] <kirk_wallace> I am thinking about getting oversized balls.
[00:09:11] <atmega> no error message?
[00:09:14] <Paragon39> can you read open the file with vi editor?
[00:09:14] <Guest334> nothing
[00:09:17] <Guest334> yes
[00:09:20] <Guest334> I can edit it
[00:09:47] <markpictor> Guest334: are you sure that it's the same file, and not a file with the same name but in a different directory?
[00:09:49] <Emcrules_Laptop> Is it the balls? I noticed a big design issue between an actual bridgeport VS my import
[00:09:58] <Paragon39> Can you see the files when selecting file open from emc?
[00:10:09] <atmega> run emc from teh console and look for something in the output?
[00:10:18] <Guest334> no, it is the right file. I've tried putting the file in multiple directories and trying all of them. My hunch is that it is a permissions thing but I didn't see anything wrong
[00:10:29] <Guest334> Paragon - Yeah I can.
[00:10:37] <Guest334> atmega - interesting idea
[00:10:46] <Paragon39> chmod 777 file name then try it...
[00:10:56] <Guest334> I will try 777 first.. that's easy.. brb
[00:11:06] <kirk_wallace> Is the_wench a real person?
[00:11:42] <atmega> a linux chick with permanent PMS
[00:11:54] <Emcrules_Laptop> and time delayed!!!!!
[00:12:05] <Guest334> 777 perms didn't help.. still nothing
[00:12:22] <Guest334> what will happen if you give emc a file that it doesn't recognize? Will you get an error?
[00:12:38] <Guest334> It is conceivable that the gcode file I'm using isn't in a format that emc can recognize.. maybe
[00:13:21] <Paragon39> vi the file the hit :set list are there any strange characters at the end of the lines?
[00:13:38] <Paragon39> :set list
[00:14:24] <kirk_wallace> My screws have single nuts. I think dual nuts with preload is the best way to go, but I haven't had enough experience to be an expert.
[00:14:41] <Guest334> paragon what were the keys? it converted to a smiley face here
[00:15:01] <atmega> where did the file come from?
[00:15:03] <Paragon39> colon set list
[00:15:26] <Emcrules_Laptop> Kirk did you install the scres the same way the lead screws came out?
[00:15:36] <kirk_wallace> Yes
[00:16:25] <Paragon39> Guest334: Ive never had an issue opening a file except when perm are incorrect.
[00:16:55] <Guest334> ahh so there are ^M at the end of each line
[00:17:03] <Paragon39> ok...
[00:17:05] <Guest334> windows to unix conversion issue
[00:17:20] <Guest334> maybe?
[00:17:29] <atmega> got dos2unix installed?
[00:18:08] <Guest334> no.. but I found a way in vi to remove them using a regexp
[00:18:17] <Paragon39> Yep you can remove them with this ... colon 0,$s/ctrl v return key//g
[00:18:17] <Guest334> I'll go try that
[00:18:18] <Emcrules_Laptop> KirK:My machine the screw is fixed on one end and the other end is left to float. I have less than .0005 backlash. the reason i mention this is due to my original lead screws were mounted the same way. However original bridgeports do not mount the same way.
[00:18:58] <Paragon39> from within vi
[00:19:54] <kirk_wallace> Hiwin has a number of different screw lines, I got the standard rolled screws. I described what I was doing, and asked for preloaded screws. After getting the screws and finding the backlash, the sales person said "tough luck, you got what you ordered".
[00:19:56] <Guest334> yup.. done, EMC still does nothing
[00:20:26] <atmega> exit emc, run it from a terminal
[00:20:36] <Guest334> yup.. that's the next thing to try. brb
[00:20:47] <Paragon39> What happens when you execute emc from a shell then try opening are there any errors?
[00:21:17] <Paragon39> atmega: You beat me too it :-)
[00:22:02] <markpictor> Guest334: from a terminal, try running 'file my-gcode-file.ngc'
[00:22:10] <Guest334> bingo! it works from the terminal.
[00:22:14] <markpictor> that should tell you if there's still something funny with the text
[00:22:22] <Guest334> it opened my file fine.
[00:22:28] <markpictor> strange
[00:22:29] <Paragon39> Weird....
[00:22:31] <Guest334> there is something weird with permissions I bet
[00:22:40] <Guest334> I happen to be running as root in the terminal that I opened it from
[00:22:46] <Paragon39> Whats the owner ship of the file?
[00:22:55] <Guest334> root root, 777 perms
[00:23:10] <markpictor> what about the dir the file is in?
[00:23:11] <Paragon39> did you use live cd to install?
[00:23:17] <Emcrules_Laptop> Kirk: Funny I bought the same rolled screws the only spec they would claim was the lead accuarcy/foot: Just thought I would ask I saw that you had a B@##$ of a time with Hiwin. just thought it was weird that bridgeports dont trap one end of the screw and my import did.
[00:23:19] <Guest334> livecd install, yes
[00:23:31] <Guest334> file is in /tmp which is also root 777
[00:23:53] <kirk_wallace> I put a dial indicator on the end of the screw and got very little side play of the screw itself, but I don't remember exactly how much.
[00:23:59] <Paragon39> Could try and chown emc:emc filename
[00:24:13] <markpictor> hmmm. I remember running into unexpected difficulties with some file due to the dir's permissions, but it's been a long time
[00:24:25] <Guest334> ok, I'll try that.. at least it is loading now.. thanks a bunch guys
[00:24:33] <Guest334> and/or gals
[00:24:36] <Paragon39> or try and put the file in the emc2 home dir
[00:24:56] <Guest334> now time to go cut something.. first time.. we'll see if this works.
[00:29:12] <Paragon39> Does anyone know how these work http://newall.co.uk/technology/ I mean do you think it is possible to make something similiar? I bought a some 4mm id carbon fibre rod and filled it with some ball bearings I then wound a primary coil about 200 turns of .125mm litz in the middle and two secondary about 20turn 4mm wide pick up coils at each end of a turned and bored piece of delron rod.
[00:29:50] <JT-Shop> I think they work like resolvers
[00:30:28] <kirk_wallace> I seem to recall the Bridgeport has an angular bearing on each end of the X, with the Y, one end is free of course. My Shizouka looks like it has a much better arrangement, with a pair of radial load bearings, flanked by thrust bearings. The far end floats in a standard bearing.
[00:31:38] <Paragon39> JT-Shop: I have them on my mill but was quite interest in making / experimenting. Granted I don't expect to get the same resolution but would like to put something together homebrew style.

[00:33:07] <JT-Shop> DIY is a fever sometimes lol, you should see the mini crane I built to raise trusses
[00:34:27] <Emcrules_Laptop> KirK: Yep My "First" (BP Clone) is the same arangement as your shizouka. I was just thinking that that may have been part of your problem.
[00:34:36] -!- jrshaul has quit [Quit: jrshaul]
[00:35:08] <Paragon39> I can see the wavefoms change on the pickups on the ocilloscope when driving primary with a function generator. but looking at the diagram at the link above they have the primary shown to be at the end and the secondary in the middle (the large coil) I was working on the assumption that it worked similiar to an LVDT http://www.rdpe.com/displacement/lvdt/lvdt-principles.htm
[00:36:26] <kirk_wallace> Emcrules_Laptop: I could be wrong, but I think the dial indicator on the screw end would have picked up the bearing lash.
[00:41:08] <andypugh> Paragon39: Looks interesting. I too would be tempted to wire it like an lvdt, with a secondary each end of the primary, with the secondaries offset by integer + half ball lengths.
[00:41:51] <andypugh> You might even want 4 secondaries, as two bridges...
[00:42:50] <Paragon39> andypugh: Exactly my thoughts but that does not appear to be the way Newall seem to be acheiving it does it? Or does it?

[00:43:29] <andypugh> Have you seen skunkworks Accupin diagram?
[00:44:41] <Paragon39> No but they have a world wide patent so one could sell it... unless you are from China I guess ;-) No I havn't seen Accupin ?
[00:44:52] <andypugh> http://www.cnczone.com/forums/general_electronics_discussion/103451-way_back_machine_ge_accupins.html
[00:44:54] <Paragon39> could = could not...
[00:45:01] <Paragon39> taking a look...
[00:46:47] <Paragon39> first two link are showing nothing... the last looks interesting...
[00:46:51] <andypugh> Something odd there, I think you might have to take the URL from the second post as the basis for the wierdly munged ones in the first
[00:47:18] <Emcrules_Laptop> Kirk: I thought so too. My old lead screws had a thread for a trap nut on one end of the screw. When I got the HIWIN screws ,that did not have a thread for the trap nut it forced me to ask why. My conclusion was that the bridgeport design allowed for some slop between the end brackets that "could" present an issue.

[00:49:48] <andypugh> If the output is anything like a resolver, then I have an Arduino-based approach documented here:
[00:50:07] <andypugh> http://wiki.linuxcnc.org/emcinfo.pl?ResolverToQuadratureConverter
[00:50:48] <andypugh> (generates the excitation sine wave and then measures the voltage synchronous with that)
[00:51:05] <Paragon39> andypugh: the pdf has turned my machine into a snail .. lol just looking at the circuit now...
[00:51:41] <andypugh> Recreating a 1964 circuit is probably a silly idea. The Arduino is so much easier.

[01:04:36] -!- Dallur has quit [Quit: Leaving.]
[01:06:28] <kirk_wallace> Looks like there is a dual bearing on the left side and a single on the right side. I suspect the pair are angular contact. It has been a year or more since I was working on my Bridgeport, but I don't recall that mine would be different than the drawing, except I had a power feed on the right side.
[01:12:29] <Emcrules_Laptop> Kirk: yeah Mine Setup is different the screw is not held tight between the bearings by the handles. There is about a 1" nut underneath the graduation dial holding the screw between two roller beaing and two thrust bearings. this is only done on one side of the screw and the other end floats.
[01:14:02] -!- Guest83960 has quit [Quit: Leaving]
[01:15:29] <kirk_wallace> Emcrules_Laptop: I think mine is like yours except the right end of my screw floats in the right side bearing. This is to keep the screw from thrashing when the table goes far right.
[01:18:06] <kirk_wallace> In fact now that I am beginning to remember, I think there is a collar that bridges the power feed shaft and the screw, so with the power feed removed I have nothing supporting the right end.
[01:19:33] <kirk_wallace> It's a little embarrassing not to know more about my own machine.
[01:22:27] <kirk_wallace> You can see in this picture, I used a collar to connect the axis motor to the stub end of the lead screw, http://www.wallacecompany.com/machine_shop/bridgeport/00005-1a.jpg

[02:00:55] <elmo401> hi room. that Heidenhain 426 spindle encoder I have, would it operate properly with something like this? http://qurl.org/s61
[02:01:05] -!- ries has quit [Quit: ries]
[02:02:07] <elmo401> it says it is the link between up to four incremental quadrature encoders and the computer
[02:02:18] <SWPadnos> probably, but if you're going to spend that much, I'd suggest getting a Mesa 5i20 or 5i22 instead
[02:02:25] <elmo401> how do I know if my encoder is a quadrature?
[02:02:56] <SWPadnos> by the part number and manufacturer specifications
[02:03:27] <elmo401> ebay doesn't have any 5i20/22
[02:03:38] <elmo401> well, none that I see with my searches
[02:04:04] <SWPadnos> http://www.mesanet.com
[02:04:28] <SWPadnos> the 5i20 is $199 list, the 5i23 is $229 I think (larger FPGA, smaller card)

[02:31:33] <Emcrules_Laptop> whats a popular choice for feed and spindle override selectors. Im looking at cheap rotary encoders from digikey. http://lgrws01.grayhill.com/web1/images/ProductImages/Series%2025L%20Encoder.pdf any thoughts?
[02:32:45] <atmega> anyone know how to un-extrude something in autocad?
[02:32:53] <atmega> 'flatten' messes up my curves
[02:37:19] <Emcrules_Laptop> mechanical desktop?
[02:38:00] <atmega> plain autocad
[02:38:08] <atmega> but, I could load mechanical if that would help
[02:40:20] <Emcrules_Laptop> i thought you just right clicked on the feature and delete it.
[02:41:44] <Emcrules_Laptop> that could be the solidworks in me talking as well havent used mechanical in a while
[02:47:43] <atmega> I'd settle for just seeing the top section
[02:51:14] <Tom_itx> change the height of extrusion to 0?
[02:52:45] <atmega> wont' take it
[02:53:07] <Emcrules_Laptop> one sec i will boot up acad
[02:53:21] <Tom_itx> i haven't used it in ages
[02:54:28] <Tom_itx> thickness
[02:54:57] <Tom_itx> or possibly a combination of elevation and thickness

[03:00:18] <atmega> yes
[03:00:30] <atmega> 'seeing' it is ok, I just need it to be 2d again
[03:02:17] <Emcrules_Laptop> what if you explode it?
[03:02:36] <Emcrules_Laptop> and just keep the 2d profile
[03:03:31] <Emcrules_Laptop> Just did it with a simple cube and it worked
[03:03:56] <atmega> cannot explode spline
[03:04:26] <Emcrules_Laptop> Well tell it to be a simple cube. LOL
[03:04:45] <Emcrules_Laptop> What about push pull command
[03:04:55] <atmega> in autocad?
[03:05:06] <Tom_itx> never heard of that one
[03:06:52] <Tom_itx> is it a flat extrusion?
[03:07:41] <Tom_itx> can you create a plane on the top of it to get what you need?
[03:08:12] <atmega> heh, no clue
[03:08:22] <atmega> I'm marginal at 2d
[03:08:24] <Tom_itx> i'm just tossing out ideas
[03:09:21] <Tom_itx> what happens when you type in 'extrude', pick it as the object and change the elevation?
[03:11:05] <atmega> lots of weird messages
[03:12:07] <Emcrules_Laptop> Sorry PressPull ctrl +alt
[03:12:48] <Tom_itx> i'm not current on acad either
[03:12:57] <atmega> is that a mechanical add-on?
[03:13:02] <Tom_itx> they've likely added that
[03:13:39] <Emcrules_Laptop> im using electrical 2008 with solids turned on
[03:14:06] <Emcrules_Laptop> Icon is right beside extrude
[03:14:19] <atmega> is there a command to join lines?
[03:14:28] <Emcrules_Laptop> yes
[03:14:33] <Emcrules_Laptop> extend
[03:15:36] <Tom_itx> what does solidworks have as a cam addin?
[03:15:58] <Emcrules_Laptop> Lots just depends on what you want to pay for
[03:16:00] <atmega> ahh.. that should make it fixable anyway
[03:17:16] <Emcrules_Laptop> I dont think solidworks makes thier own cam plugin. the just hand out the API and get others to write add-ins
[03:17:28] <Tom_itx> no i didn't think they did
[03:17:35] <Emcrules_Laptop> Visual Cam is a nice one but 5k for a seat
[03:17:38] <Tom_itx> that's the kicker to alot of cad packages
[03:17:57] <Emcrules_Laptop> Alibre has a cam package
[03:18:07] <Tom_itx> i still use an ancient copy of smartcam
[03:18:14] <Emcrules_Laptop> it's the same as visual mill
[03:18:16] <Tom_itx> just use it for my own stuff now
[03:18:33] <Tom_itx> before solids hit the market hard
[03:18:40] <atmega> are any affordable for normal people
[03:18:55] <Tom_itx> bamcam
[03:18:57] <Tom_itx> iirc
[03:19:19] <Tom_itx> cambam
[03:19:20] <Tom_itx> sry
[03:19:30] <Emcrules_Laptop> alibre is $99
[03:19:35] <Tom_itx> http://www.cambam.info/
[03:19:38] <Emcrules_Laptop> no cam though
[03:19:39] <atmega> yeah, I keep meaning to try cambam
[03:19:52] <atmega> I bought a copy of cut-2d, but I'd like 2.5
[03:19:52] <Tom_itx> i gave $8k for what i have well over 10 yrs ago
[03:21:12] <Emcrules_Laptop> Im working on a robot project using catia to program the robot lets say $80K for a seat
[03:21:13] <Tom_itx> it eventually got replaced with catia
[03:21:29] <Tom_itx> yeah that's about right for catia
[03:21:43] <Tom_itx> it was $75k at the time
[03:22:00] <Tom_itx> and still didn't have a cam interface
[03:22:25] <Emcrules_Laptop> catia has native cam now
[03:23:30] <Tom_itx> back then we mainly imported from catia and cadam
[03:23:36] <Emcrules_Laptop> we are using catia cam functions to create robot tool paths. Delmia to simulate the program and another package to post process the cam to abb robot rapid code
[03:24:31] <Emcrules_Laptop> Sometimes it feels like walking backwards while looking in a mirror
[03:28:46] <Tom_itx> are the robots for assembly or machining?
[03:29:41] <Emcrules_Laptop> machining/Deburring
[03:40:28] <atmega> The free beta of DraftSight is pretty good
[03:40:58] <atmega> (on a different note)
[03:51:37] <atmega> robots for resistance flash removal?

[09:02:16] <HDB10> Valen: yes I mean the log file .
[09:03:53] <HDB10> This is what I am reading: (which in turn would use the "traditional" G38.2 with its logging

[09:10:08] <Valen> ie you give it a file name and when the probe contacts it will write out the value when it touched

[09:13:22] <Valen> right so whats the problem?
[09:13:30] <Valen> and whats it got to do with home position?
[09:13:59] <HDB10> Do you know the syntax for this please ?
[09:15:13] <Valen> I did once
[09:15:30] <Valen> was fussy to get right
[09:15:31] <Valen> hmm
[09:15:38] <HDB10> OK not to worry I see if I can find it.
[09:15:56] <Valen> somebody had a sample program i used as the base

[09:18:36] <Valen> take a look in smartprobe.ngc
[09:18:41] <Valen> should be somewhere in emc
[09:22:30] <HDB10> OK will do :-)

[09:23:43] <Valen> I used it to make the graph here at the bottom of this http://www.cnczone.com/forums/calibration_measurement/109146-contact_probe_build.html
[09:24:49] <Valen> I think basically you issue a comment
[09:24:56] <Valen> (PROBEOPEN filename.txt)
[09:25:05] <Valen> then G1 to wherever you want to go
[09:25:23] <Valen> then do a G38.2 and it'll move till it hits
[09:25:33] <Valen> and write out the result in the file
[09:25:52] <Valen> (though I'm not sure if you can read it until you do the probeclose comment)
[09:26:03] <HDB10> I got you .
[09:26:13] <Valen> filename.txt goes wherever the ini file your using is
[09:26:22] <Valen> and it was a bitch to change for some reason
[09:26:43] -!- pjm__ has quit [Ping timeout: 255 seconds]
[09:26:45] <Valen> so G1 to 5mm above the work piece
[09:26:50] -!- grandrew has quit [Ping timeout: 240 seconds]
[09:26:52] <Valen> then G38.2 until it hits
[09:29:17] <HDB10> I place the following line in the hal file : net probe parport.0.pin-10-in => motion.probe-input
[09:30:28] <HDB10> It stops immediately at the moment as I need to sort out 0 or 1 as the case maybe.
[09:30:55] <Valen> if its tripping the probe input axis will say
[09:31:08] <HDB10> How do you start it again to proceed beyond the touch point ?
[09:31:43] <Valen> probe back off
[09:33:30] <HDB10> Say the touch point is 300 Deg in my case and I want to go the 360 Deg, can I do that ?
[09:33:32] -!- grandrew [grandrew!~Andrew@83.149.8.216] has joined #emc
[09:34:12] <Valen> whilst the probe is still "on"?
[09:34:32] <HDB10> Can I turn it off ?
[09:34:43] <HDB10> and then proceed
[09:35:10] <Valen> dunno, havent needed to do that
[09:35:20] <Valen> but i vuagley recall something like you could
[09:35:41] <HDB10> or I guess reset the probe to 400 Deg ?
[09:36:19] <Valen> I'm not sure where the degrees are coming from
[09:36:38] <HDB10> G38.2 A 400
[09:36:51] <Valen> dunno
[09:36:57] <Valen> would have to look at it
[09:37:04] <HDB10> The A axis is a rotary device.

[12:27:42] <HDB10> jthornton: How do you restart the program after the probe stops the program ?
[12:28:02] <jthornton> for an error?
[12:28:50] <HDB10> No when the probe has stopped the program.
[12:30:42] <jthornton> this is my touchoff subroutine that I use on my plasma http://pastebin.com/Fd0PB4EG
[12:31:12] <HDB10> OK I take a look at it now TKS.
[12:31:47] <SWPadnos> probing shouldn't stop the program unless there's an error (like the probe never hits)
[12:32:15] <jthornton> yea
[12:32:18] <jthornton> xy
[12:32:19] <the_wench> The X-Y problem is when you want to do X, but you don't know how. You think you can hack X if you can just do Y, but you don't know how to do Y either. You ask (us) for help with Y. We think Y is a strange problem to want to solve... So just ask us about X.
[12:32:37] <jthornton> I love that one :)
[12:33:00] <SWPadnos> I was just going to ask it to shut up, but then I saw your "xy" comment

[13:02:05] <HDB10> How is the temp over there ? We are doing 31 C 70% Humidity :-(
[13:03:22] <psha[work]> -10 i guess
[13:03:42] <psha[work]> very nice weather for bike...
[13:03:54] <psha[work]> but only if there will be a bit less idiots on the roads...
[13:04:25] <HDB10> You think so ..... You will cook in this weather
[13:04:30] <psha[work]> i've crashed with a car on the second crossroad from my home ;)
[13:06:21] <HDB10> Black ice ???
[13:06:24] <psha[work]> no ice, clear road but when you don't look on the road it's hard to nitice bike on main road ;)
[13:07:43] <HDB10> I guess they use a lot of salt on the roads over there ?
[13:08:17] <psha[work]> no, last two years salt is not used
[13:08:45] <HDB10> How do they keep t free of ice then ?
[13:08:50] <psha[work]> mostly sand or some chemicals that i don't know
[13:09:15] <HDB10> I see that's new to me.
[13:09:56] <HDB10> How did the Guy on the bike get on ?
[13:10:57] <psha[work]> the guy on the bike was me ;)
[13:11:24] <HDB10> Oh Shit ! So how did you get on ?
[13:12:21] <psha[work]> fine ;) i'm has much experience in winter biking and car was turning and thus moving slow enought

[21:19:00] <mrsunshine_> well anything then! :P
[21:19:12] <mrsunshine_> but spindle speed, what would be a minimum max rpm to target when rebuilding
[21:20:06] <ries> mrsunshine_: I cannot speak for alu and only wood, but I would say 8K rpm for wood till 24K, if you use a spindle
[21:20:29] <mrsunshine_> hmm ok, cause all mine can do atm is 2k =)
[21:20:36] <mrsunshine_> its a tad bit slow for mdf i feel :P
[21:24:23] bootnecklad_ is now known as bootnecklad
[21:24:44] <mrsunshine_> hmm, maybe a washingmachine motor should fit the bill :P
[21:24:55] <mrsunshine_> looking at the rpm they can reach with that big drum on it :P
[21:25:46] <mrsunshine_> and a washing machine has to have some kind of way to rpm control the motor also
[21:26:02] <mrsunshine_> as it can start very slow, then go faster, then slower then do the centriuge thingie
[21:27:11] <mrsunshine_> or they might not be so highly rpmed?
[21:27:34] <mrsunshine_> nop, like 1000 - 1600 rpm
[21:27:37] <mrsunshine_> just sounds alot faster :P
[21:29:03] <LawrenceG> mrsunshine_, I am playing with a nice washing machine motor top speed is 16000rpm, 3phase design... am trying to reverse engineer the drive
[21:29:28] <mrsunshine_> nice =)
[21:29:50] <mrsunshine_> i realy need to change the spindle motor on this mill, i wonder what usaly goes broken on washing machines that is left at the dumpyard :P
[21:29:57] <LawrenceG> It would make a nice spindle motor.. and tons of them are going to the landfill every day

[21:33:12] <archivist> washing machine motors only have cheap bearings you will need your own spindle
[21:34:49] <LawrenceG> yes... belt drive works well... existing belt system is a multi V type that drives the drum
[21:35:32] <mrsunshine_> archivist, well the actual spindle thingie is left, just the motor and mounting will change
[21:35:38] <mrsunshine_> maybe the bearings in the existing spindle also :P
[21:37:48] <mrsunshine_> but might be a cheap and good way to increase my rpm output =)
[21:38:55] <LawrenceG> the problem is the controller on my unit takes switch inputs from the timer and runs canned cycles... I need to hack it to accept direction and speed inputs
[21:39:49] <LawrenceG> I was thinking of a direction signal and a pwm signal where 1000hz= 1000rpm and 16000hz = 16000rpm
[21:39:52] <archivist> the windings look like normal 3 phase perhaps a standard vfd could be used
[21:40:57] <LawrenceG> probably... not sure what the upper freq range is to get 16000rpm... havent determined how many poles there are in the motor
[21:40:59] <archivist> or..I nag my friend who has a shop repairing domestic appliances
[21:43:53] <mrsunshine_> =)
[21:45:55] <LawrenceG> the controller I am playing with has an analog devices microcontroller.... devel kit is available for free.. I have not got to the point where I know if I will be able to dump the code via the debug port
[21:50:46] <archivist> probably not as the washing machine companies do like to control the use of their controllers
[21:51:00] <mrsunshine_> hmm, but maybe a bit big? :/
[21:54:22] <ries> mrsunshine_: 2K sounds very slow to me for wood routing
[21:54:54] <mrsunshine_> aye
[21:54:55] <mrsunshine_> it is
[21:54:59] <mrsunshine_> not at all good cuts =)
[21:55:12] <mrsunshine_> mdf "works" but not very good

[22:57:26] <archivist> frank222, there is a define PACKAGE_STRING which has the version
[22:58:50] <frank222> Thanks, that's what I'm looking for.
[22:58:50] <archivist> in my dev copy its #define PACKAGE_STRING "EMC2 2.5.0~pre"
[22:59:20] <archivist> its in config.h
[23:01:21] <SWPadnos> the structure contents shouldn't be an issue if you compile your code with the same headers as emc is compiled with. Are you trying to determine the version of a remote NML-speaking progeam?
[23:01:29] <SWPadnos> program
[23:01:59] <frank222> No, just if my version has been compiled against the correct version of EMC.

[23:03:02] <frank222> The version I'm running was built against 2.3, but when run against 2.4, it gives funny results. Obviously the struct has change and the fields no line up.
[23:03:46] <SWPadnos> right. the PACKAGE_STRING probably won't help there, since I don't think there's any way to ask another NML-speaking program what its version is
