[Emc-users] converting parport to 5i20 config - joint following error
I started converting my EMC2 mill from parport to the Mesa 5i20 hostmot2 stepper and got stuck with a problem. The parport configuration works fine but the hm2_stepper config is having problems. I keep getting joint xxx following errors. I checked the docs but cannot explain this: ferror, min_ferror, max_velocity and mac_acceleration are the same in both cases and - although not necessary - I added the base_period to the hostmot2 configs. A second problem (maybe related ?) is seen during a manual jog. When an axis stops it keeps humming and the digital readout flips between the current position (e.g 2.001) and adjacent positions (e.g. 2.002). This was all done on 2.3.0~beta2 with the hm2_stepper config files from that release. Any ideas?

There's also no [TRAJ] acceleration limits, i'm not sure what it will do in that case.

Jon Should I try a test on my machine? If so what would it look like? There is a test file, threading.ngc, in the /usr/share/emc/ncfiles directory. (There may be another version of this file that is MUCH shorter, about 15 lines. But, I have been working with the longer one in the /usr/share dir.) Anyway, in the longer one, about halfway down, is #4=0.05 (thread pitch) which sets up for 20 TPI. I ran it like that first, then changed the value to .08333 to get 12 TPI. You can also twiddle with the lead-in, lead-out scheme and the depth of cut. I left it with a very small increment (#2=) so I'd get a lot of passes, to see if anything went wrong. I had no failures here. I'd greatly appreciate your trying it there, just to see if there is some random problem. I cannot understand how the spindle sync would work prefectly for hundreds of parts at ~20 TPI and fail on roughly 50% (I think he said that in an earlier message) at 12 TPI. The spindle sync function has no way of knowing what the thread pitch will be! Thanks, Jon -- This SF.net email is sponsored by: High Quality Requirements in a Collaborative Environment.

Re: [Emc-users] converting parport to 5i20 config - joint following error
Sebastian, Another brave hm2 testing volunteer! Welcome! Yep, slow system, problems with parport and not enough I/O made me buy two 5i20 cards (and a 7i43) card. One 5i20 for the main system, one as a backup/second system at home and the 7i43 to play around with and try some FPGA programming. I set up a 'new' system with EMC2 (Ubuntu 8.0.4 LTS release) from the live CD, updated this to 2.3.0~beta2 and started to play around with it. Both with my existing parport and with the new hm2 config. In my situation (milling a curved surface with a radius around 30 cm in all 1mm long line pieces) the hm2 config is 10% faster than the parport one. One problem with the configs you linked below is that [TRAJ]MAX_LINEAR_VELOCITY is greater than [AXIS_?]MAX_VELOCITY. That means the hm2 stepgen will fall behind where the trajectory planner wants it to be, leading to following errors if it gets too bad. This did the trick. I changed/added the [TRAJ] parameters and now even tort.ngc works almost perfectly! Almost ... the first time I start EMC it still gives a joint following error on axis 0 but if I quit and restart it's OK. There is still a lot to do in cleaning up the configs and making sure that all my other I/O gets in there but this is a promising start. The humming and dithering across the setpoint is a known bug in 2.3.0~beta2, it's been fixed in CVS and will be in the next release. I could not resist; 30 to 45 minutes of downloading and compiling and I have the trunk running. Humming and dithering is fixed. Still works almost perfect. One very small thing is that the splash screen reports 2.4.0~pre and the title bar of axis 2.3.0~beta1 but I think I can live with that ;-) Thanks, Rob -- This SF.net email is sponsored by: High Quality Requirements in a Collaborative Environment.

Please let me know if I have miscalculated in drawing up my plans. The SheevaPlug supports USB, i2c and serial so this is how I will interface to a stepper controller board. The SheevaPlug is advertised to cost $99 in onesies. http://www.marvell.com/products/embedded_processors/developer/kirkwood/sheevaplug.jsp It has a 1.2Ghz processor. Since the ShivaPlug supports 1G Ethernet, I planned to send commands to it via ethernet. My next step is to select a suitable stepper controller board.

Re: [Emc-users] My plans are to use a SheevaPlug to power EMC 20090414 99suspense
As far as I know, rtai (the real-time kernel that emc2 uses on x86 ubuntu systems) does not currently support the Sheeva ARM CPU. Before emc2 can run on a system to control hardware, you have to either port a supported rtos to it, or port rtapi to an rtos that is available for that system. It is not impossible, but it will require a great deal of effort from a programmer familiar with RTOS and low-level operating system details.

[Emc-users] NAMES, this weekend (4/18-19, 2009)
This is a reminder that the North American Model Engineering Society Expo (NAMES) is this upcoming weekend (4/18-19, 2009) in Toledo, Ohio. This is a fun show--many model engineers with some very impressive model engines and devices of all kinds. Also new and used tooling, machine tools (manual and CNC), related books, and materials. And free seminars (no CNC seminars this year?). http://www.modelengineeringsoc.com/expo.htm Some EMC supporters will have a booth (B-15, in the back) where we'll be handing out 200 Live-CDs with EMC2, demonstrating EMC2 on a mill, handing out flyers, and in general making folks aware of this excellent software. http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?EMC2AtNAMES Jon Elson and Steve Stallings will have booths nearby. If you're coming to the show, we're still looking for volunteers to be at the booth. An hour, even half an hour would be helpful and probably even fun. Send me an email. But, it looks like we'll have a cellular internet connection there, so another way to help would be to monitor the EMC IRC channel during Saturday and Sunday (9-6 and 9-4)--if there are questions people have that folks in the booth can't answer, we may try to use IRC for quick answers. (If you'd like to volunteer your phone number as a backup, you can email me personally.)

And picture boards are _nearly_ complete - just need to make the back leg so they can freely stand on their own if needed. Check 'em out, after the show I'll coordinate with Alex Joni getting the boards posted onto the linuxcnc website, and you'll be able to see the whole layouts clearly and one by one.

If you're coming to the show, we're still looking for volunteers to be at the booth. An hour, even half an hour would be helpful and probably even fun. Send me an email. Please if you're there and aren't running your own booth, please consider taking a short shift at the booth (tell the wife and kids they can go to the mall that's a 15min drive away and spend some money :--) ). As of the last time Dale and I corresponded I was the only other worker and can really only manage one shift a day due to my fibromyalgia. But, it looks like we'll have a cellular internet connection there, so another way to help would be to monitor the EMC IRC channel during Saturday and Sunday (9-6 and 9-4)--if there are questions people have that folks in the booth can't answer, we may try to use IRC for quick answers. (If you'd like to volunteer your phone number as a backup, you can email me personally.) Many thanks to Marty (CDs), Greg (photos), Wayne (banner graphics), No need for thanks. It's my chance to give back to the community (though donating cash to the project would probably be better because all I'm doing is advertising more and making more work for them...). The real thanks go to (aside from the developers who've made this all possible) all the people who graciously donated their pictures and machine information for use in assembling very descriptive representations of their machines and the work the do on them. I know it's cheesy but I will probably bring a turner's cube (not internally separated though) as a display piece. Rab (Chips graphic), and Bob (who will be driving my machines down). --Dale Quick question Dale - Will there be a laptop or other machine available for videos to be played back on? A number of the people who donated also sent me video files. I can do a quick stitch of them which we could have running in a loop at the booth. I'd offer my laptop but I can't be without it for longer than my already volunteered shift (call me greedy/needy - but actually I'll have some real work I need to do this weekend). -- Stay on top of everything new and different, both inside and around Java (TM) technology - register by April 22, and save $200 on the JavaOne (SM) conference, June 2-5, 2009, San Francisco. 300 plus technical and hands-on sessions.

Re: [Emc-users] syncing two motors to one axis
Oops, I meant that I had to add a NOT because of the inverted direction signal... Also, beware - there is a line with two nets in it that are actually on two separate lines. Not sure why my text editor did that - looked fine when I hit send.

Re: [Emc-users] [OT] Brushless Hall Sensors
Kirk Wallace wrote: Do the Hall commutation sensors, on BLDC motors, output analog or digital signals? Is there overlap in the timing or is there possibly a gap between one Hall output and the next? Generally it is supposed to be a digital signal, but on motors that use bare Hall sensors (rather than really using some sort of encoder) then there may be a less digital nature to them. With 3 Hall signals, there are 8 possible states. The only states consiered invalid are all high, or all low. The way they work, generally, these states would never exist, so it will always have either 1 or 2 signals high, and only one should ever be changing at a time.
