That's really strange - I don't know what to suggest. > Cinci - had the max FE set to .003 - went to .007 - went to .030 - > went to .1 - runs w/o fe at .1 > I brought up halmeter to watch the fe during the table > movement - I never saw more than .001 Halmeter only updates a few times per second. Can you set up halscope? There are pins (or maybe parameters) called axis.n.ferrror, which is the amount of following error, and axis.n.ferrored, which is a bit that goes true when EMC trips on excessive following error. Use the "ferrored" pin to trigger the scope, and capture position command, position feedback, and the ferror pin. If you can capture some traces, that might point us in the right direction - could be a sudden change in command that the motors can't follow, or an issue with feedback, or perhaps everything is fine that it is a false trip. The traces will let us know which case we're dealing with. > cvs updated trunk about two weeks ago > > I will gladly entertain ideas. The faults just started in the last few days? NOT when you updated last?
