I am having a really hard time finding any EMC PID values that make it better then the graph I sent before. I can make it much worse by adding even just a little P ie, p=1, p=1.1, p=1.01 - not to mention P=10 or higher. It looks a little smoother, rolling down to zero but starts off at tenths or hundredths of inches before doing so. If I change FF1 to anything other than 1, even 1.01, I get a much worse result (tenths of inches of ferror) and sometimes immediate faults if it is much higher than 1. I've tried some I term and even some D term (and combinations of both just for the fun of it). I can't get anything that has lower following error than having everything set to 0 and FF1=1.
