After a bit of playing around I am within about +/- 8 counts, no matter what I throw at it. Feeds are within about 6 counts. Grabbing hold of the servo shaft and trying to turn it by hand as hard as I can deflects the position by about 8 counts before it returns to 0.
I first tuned PID as good as I could get then turned I down to 0 and the other two down to about 20%. I then set up FF1 and FF2 to give the minimum following error. Finally I turned P,I,D back up to their previous values. I think that is pretty much as good as I am going to get.
