I will try torque at some point I think. I'm sure the issue is with the drive speed and torque PI loops. How have you gotten on with setting the drive PI settings? I'f i put it in open loop I think the axis will drift and I don't think I could command an analog signal? or maybe I could?
I believe that torque mode is more difficult . I am using step/dir not analogue which should be easier.

I will be away for a few days but will catch up on my return.
