Hello! I have spent hours in plural trying to figure out, what is wrong and this is driving me nuts. Here is a video with that motor in action (I was jogging it back and forth): http://www.youtube.com/watch?v=RA4mdp1rYfs
That noise starts at 0:14. 1) it is there only when moving to the right; 2) it is the only motor doing such a noise; it is a gantry machine, motor on the other side and the motor that sits on the gantry are fine; 3) PID tuning of these motors was done 2 years ago, problem started few weeks ago (according to client); I retuned PID today, difference in parameter values can be expressed in orders of magnitude (P was 400, now it is 15 etc.) 4) I watched encoder velocity pin in HalScope, it is fluctuating, so that comes form motor; Is it some mechanical problem? Is that encoder? I would appreciate any tips, where to look. Thanks in advance! -- Viesturs If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
