Thor, or should that be Zeus?

Chaz,
For the kinco drivers you have you should tune the velocity loop with the autotuning with the load applied. (connected to the ballscrew and table mass) and once done, you can then do the tuning with the cslabs controller. the tuning fails, reset the driver to defaults, set the driver up again and tune again.

Ye, also heard this. The CS Labs manual states the same. My Kinco drives are like that, dont know if they are tuned or not. The Panasonics offer an ongoing autotune feature which Ill try but also concerned that it might mess things around.
