As the title says. I have an issue of "reverse backlash".

I set my backlash comp to 0. I come positive to my clock gauge, in 1 mic, touch zero, then reverse direction.

The axis moves positive still for .060mm (60 micron) only then does it change direction and reverse.

My question is there a parameter or servo setting that can cause this. Or am I dealing with faulty hardware? I've swopped the axes on the control (JS1A and JS2A), the problem stays with the original axis.

Any help or guidance would be appreciated.
