I set the Chirons spindle up as an axis, did an AutoTune then changed it to a spindle and entered the settings, I then tweaked from there.
Ok, just tried that, she was not happy.
It started to tune, set some low values and then just started thrashing back and forth wildly, had to e-stop to stop it.
It seems i can get somewhere with P=3000, i=0, d=0, kff=0 but, it's not balanced in behaviour FWD/REV so FWD seems not too bad but REV it seems to continue after the signal is removed then stop instantly. I don't know if it makes a difference but the following error is massive too.
DAC offset is 0.4v which is inline with other drives.
A short vid showing 2 FWD runs and 2 REV runs
