What's really odd is at the moment this same axis that used to be incredibly
reliable at 150 ipm with jogging now also has started

Backlash will certainly make thingsw difficult, as in effect you are
trying to tune two systems with one PID. There is the
s loaded. I'll try that.

That sounds like you could have to much Kd. Try reducing it. Do you have
an oscilloscope? An oscilloscope really helps when tuning servos. As the
UHU doesn't have an analog output you would have to probe the motor
drive signals. Put a simple R-C filter in line with the probe to filter
out the
