I thought the position error had to do with PID position but I know I commanded moves to 0 without error. I was running 2.1.branch but changed 2.1.7 when it was released a couple of days ago. I'm seeing numbers in my Axis Hal configuration watch window. Now to connect the analog out to the drives analog in and see if I can tune it. I added another limit 2.0 to the feedback rpm going into the pid loop. I limited the rate of change to 3000 rpm / sec figuring 3 rpm per 1ms servo thead fperiod. So now my negative spike generated from threading resetting the spindle position will be limited to 3 rpm in one servo period. If this thing is tunable I should have a pretty nice closed loop spindle control... hopefully!
