When I had this problem, it was a set screw on the encoder shaft that I forgot to tighten. It would almost track, but a bit of error would build up after many turns. If your encoder is differential, make sure the 7i33 is jumpered for differential mode. If it's not, make sure the 7i33 ISN'T jumpered for differential mode. Also check your grounds and as Jeff says, check the mechanical stuff, even if you already checked it once! ------------------------------------------------------------------------------ This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
