Due to an operator error this machine is no longer mechanically serviceable. I have the following for sale that was pulled from the machine: 1.Vital Systems Motenc-Lite Servo Controller and all daughter boards and cables. The daughter boards were used for the operator station only for pushbuttons and led bulbs for the pushbuttons. I also have the servo daughter board. 2.Automation Direct Sure Servo drives and servo motors (3KW). The motors have 2500 ppr encoders. The drives have an output of the position pulses for semi closed loop operation. That is how I used them and it worked great. You would need to purchase encoder and motor cables or roll your own. They have many different lengths. I do have the daughter boards and cables for the drives. All is in very good condition. Continuous duty on the motors are 15 nm and intermittent is about 46 nm. I also have the cable and tuning software for the drives. 3.I also have a Mesa Electronics 5i20 that I used for the general purpose I/O. 4.I have several opto 22 boards that were used for the GPIO. It's a pretty good mix so you tell me what you need and I will tell you if I have it. I have some other things lying around I hope to list. Make me offers for one or all. Thought I would give the people who know what this stuff is a chance at it before it hits auction. I need to buy some heavier stepper motors and drives for my router. The control was air conditioned in a climate controlled shop so all is pretty clean.

I use TPEN6_6 firmware and bldc module in "n" mode. I am rotating it slowly (setp bldc.0.frequency 0.2). PWM outputs are true sinusoidal (checked on scope), but motion has some smooth (non-linear) parts and stop parts. BTW, I can't use bldc "n6" mode, because I don't have where to connect A-high-value, A-low-value, .. because bldc component has A-value, .. pins only. When I use "n" mode, the motion is not smooth and it does not depend on strength (bldc.0.value). Shouldn't PWM curve look not like sine, but with "kinks" in the center, smth. like this: http://www.postech.ac.kr/ee/cmd/102_BLDC_pedal.htm ? My config hal file attached.

I was cutting a hand wheel out of Aluminium, using the output of a CAM program (CamBam). I was twiddling with the feeds and spindle speeds sliders, and wonder if the issue is my twiddling, or if it is with my machine. I seem to remember reading about this issue back when I started with LinuxCNC. Machine KX1 with G540 and a Mesa 5I25 in it. No errors on the console. Why did that arc shown on the blog page have the issue? Was it me possibly setting the feed speed to 0? I'll re-create the CAM program, (with shallower depths) and the feeds/speeds correct, and see if the issue was me, or the machine. The picture is on my blog, http://cnc-for-model-engineers.blogspot.ca/2013/06/hand-wheels-and-cambam-part-i.html should get you there. I won't be able to re-run the whole test for a couple of weeks (it took too long and too noisy for a midnight run). Thanks for any words of wisdom anyone may have. John A. Stewart. ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev </pre> John Alexander Stewart 2013-06-16T20:18:31 http://comments.gmane.org/gmane.linux.distributions.emc.user/44522 <pre>Hello, my name is Rene I'm also located next to Stuttgart. A meeting in Stuttgart would be very great! Me and my cousin will come for sure. We have a big working Linuxcnc machine and visiting our workshop would be no problem to us. We are currently working on something that would change Linuxcnc a lot for professional users and when I say a lot I mean really a lot ! But I will not say more at this time :) Maybe we can introduce it to you during the meeting in Stuttgart.

I have a simple configuration generated by Stepconf Wizard and only minor tweaks to make estop work. This problem also happens when I try the sim/axis and sim/tklinuxcnc configs. Sometimes Linuxcnc comes up and runs fine, but about every second or third time I launch it, I get this error: http://pastebin.com/LSJGvCJX ([EMC]DEBUG = 0x7FFFFFFF). If I just dismiss the error and launch again it comes up fine. I tried this on identical hardware set up that I dd'd this build and configuration to and it happens there as well. I was, for a while, also getting an error on exit, but now I can't seem to make that happen and I didn't capture it. The start up error is persistent however. Any idea what might be going on? -Tom ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev </pre> Tom Easterday 2013-06-15T22:52:49 http://comments.gmane.org/gmane.linux.distributions.emc.user/44507 <pre>-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've played with the various interfaces for LinuxCNC on the BeagleBone (tunneling X display data to a remote system), and touchy seems to be the best choice from a CPU usage and system integration standpoint (the 'Bone can support driving small LCD displays directly, that would work well with the large buttons in touchy but not so much with something like axis). Anyway, I'm wondering if there is a way to run touchy with a simulated jog wheel and start/abort buttons or if I have to physically wire something up. I don't much mind wiring some buttons myself, but I can't really make this the default interface for the machinekit image if people will have to dig out the soldering iron to get LinuxCNC going through the motions. I can run the touchy simulation configuration, but I have not been able to get the loaded gcode to run (presumably because I can't press the start button that isn't there). So do I need real hardware or am I missing some detail of the touchy sim setup that would give me some virtual buttons (maybe as a stand-alone pop-up window)? - -- Charles Steinkuehler charles-Iqubyy1RSnbkn7jTMgjrSQ&lt; at &gt;public.gmane.org -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (MingW32) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlG8trMACgkQLywbqEHdNFwU0QCdHp/e+q30eFOceDvlsxfLmZ/r 5ugAoLNG2tpqXSr9IoQEw/LWG/icgjVg =EWN6 -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev </pre> Charles Steinkuehler 2013-06-15T18:47:15 http://comments.gmane.org/gmane.linux.distributions.emc.user/44506 <pre>Hi guys, With all the interest of late in the history of emc, I found I still have an ancient web page up on how to build and install emc/rcslib on Redhat 6.2 (from 12-Jan-2001). http://members.shaw.ca/cncstuff/emc.html I tried to access the referenced the sources via CVS on sourceforge, but get connection refused...

I think I will need the belts to be heavier than the XL that I used on my Millrite conversion because the apron drive will require 12 inches between the pulleys. Does anyone have any reason for picking the L series over the T10 due to cost, availability, load capacity etc between the two either for the belts themselves or for the pulleys. I have done a little googling on the subject but can find no direct comparisons of the two. If anyone has positive or negative experience with either it might save me time or money down the road.

Tormach has slightly modified a bog standard Chinese 7x12 lathe with a spindle clamp and indexing plate, then fitted it up with mounts to bolt to the table of their larger CNC mill. Put a stepper on the spindle and the lathe becomes a full 4th axis/indexer/dividing head with tailstock. http://www.tormach.com/product_pcnc_lathe2.html Instead of moving the tool for CNC lathe work, this moves the entire lathe. Looks like a job for LinuxCNC. Put a 7x12 on a Bridgeport or a Unimat on a mini mill, or a 9" South Bend on a Warner &amp; Swasey #4. Or a 17x78 LeBlond on a 20 foot Cincinnati planer with a rotary spindle retrofit... I happen to have a small antique indexer with tailstock on a common frame, don't need to align the two separately on the table. Probably ought to keep it and put a motor on it or something... ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev </pre> Gregg Eshelman 2013-06-14T23:40:26 http://comments.gmane.org/gmane.linux.distributions.emc.user/44477 <pre>Kirk, If you would like I could take a few shots of my machine and send them off line or can I post them here as attachment.....

I was 4 hours into a 3D print using linuxcnc, and the machine crawled to an almost complete stop. My job was still running, but it executed 1 line of gcode, then pausing for 2 seconds. Axis wasn't showing the preview. The DRO read all 0. 'top' showed CPU at about 5% (it normally 80% or more because of axis). While the job was running, I was writing a monitoring application (on windows in c#) that would connect to linuxcncrsh and query the machine status every 5 seconds. I noticed the linuxcncrsh code reuses the nml interfacing code in halui.cc. Does this mean that linuxcncrsh uses the same nml channel as axis? Could this have been my problem? After rebooting, I restarted my job and it completed fine (it took 8 hours :( ) without using linuxcncrsh. ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev </pre> Frank Tkalcevic 2013-06-13T21:16:55 http://comments.gmane.org/gmane.linux.distributions.emc.user/44459 <pre>Kirk, Your Standard Engineering Works No. 1 appears to be the spitting image of my U.S. Machine Tools Cincinnati horizontal mill. I put a treadmill motor and controller on it and it works great. I am sure there must have been some relationship or some design stealing early on between Standard and U. S. and probably Burke because they all seem to be too close for coincidence.

I am about to introduce some new users to LinuxCNC and I want to make sure I have a good list of it's strengths. I was drawn to LinuxCNC because of HAL and programmable kinematics, but I'm sure there's a lot of features I don't even know about.

I need to repair one (Canon lens) and need some insight. Such as, is there something like a continuity check to see what part of the motor might have a fault? http://en.wikipedia.org/wiki/Ultrasonic_motor http://www.noliac.com/Files/Billeder/Pdf/Pdf%20%20external/Piezoelectric_ultrasonic_motors.pdf http://photo.net/canon-eos-digital-camera-forum/00QHjI -- Kirk http://www.wallacecompany.com/machine_shop/index.html ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev </pre> Kirk Wallace 2013-06-12T23:58:09 http://comments.gmane.org/gmane.linux.distributions.emc.user/44371 <pre>I accidentally bought another lathe from eBay. It is beautifully made, in the 1920s, with no regard to cost practicality or logic. One of these: http://www.lathes.co.uk/rivett/page2.html It isn't quite as nice as the one in the pictures, and has no changewheels or screwcutting box. (imagine is stops short at the back of the headstock). Should I CNC it? If I do, I would have to do it sympathetically. (My other hobby is vehicles from the same era). As the entire cross-slide pops off at the flick of a lever, it is not difficult to imagine a slot-on CNC cross-slide, possibly incorporating a tool turret. In this respect the conversion is easier than the Chinese lathe I converted. However, the Z-axis poses something of a quandry. There is no way at all to swap the leadscrew to a ballscrew. It sits snugly in a semicircular slot in the bed. So, perhaps I could mount a ballscrew on a bracket at the back. Then I could slot-on the CNC top-slide and bolt it to the nut, and if I wanted to use the lathe in manual mode I could unbolt it, swap back to the manual toolslide, and resort to craftsmanship. Or, I could just convert it to an electric leadscrew with an Arduino and sell it on as a working lathe. I do think it needs to be mounted on an oak cabinet like the original Rivett ones. I think that looks great :-) (Then flat-belt drive to a motor/vfd mounted underneath) </pre> andy pugh 2013-06-12T15:35:55 http://comments.gmane.org/gmane.linux.distributions.emc.user/44364 <pre>I took the little CNC Unimat lathe out to the meeting of the OVAR (Ottawa, Canada) informal railway modellers group last night. There's usually about 125 people that show up. The CNC lathe was just running a turning program, no spindle going, (no swarf to throw around over other exhibits). Interesting the comments; did not matter the age of the questioner; some good interest. Of course, many of the attendees did not really comment; these people come from all walks of life, and I'm sure many of them have never seen a lathe in operation (but are most likely better HO scale modellers than I could ever be - everyone has their own strengths) Was looking for another Unimat headstock to put a stepper motor on, so I can go quickly from "splashing brass at 5,000 rpm" to "cutting cams at 1 rpm". We'll see what the grapevine turns up. Here's my blog, I'll probably update it this coming weekend again: http://cnc-for-model-engineers.blogspot.com John A.
