Hi Rob,
I have the same driver and experiencing some problems with it too.
When I use it with KCam the motors make a lot of noise and rotate only at very low speeds - trying to increase speed results in stalling the motors.
With Mach2 the motors rotate at very high speeds with no problem and surprisingly quite. However, there is a certain mid-range were the motors stall and hum. There is no such setting in Mach2 that I've not tried to adjust, but nothing seems to cure the issue.
This range is approximately between 1500 and 3000 ppm (using full step resolution), i.e. when set to 200 steps per mm the speeds range is 450-900mm/rev. Using micro-step offsets this range to other values. Besides, I do not like using micro-step, as it drastically reduces the motor torque.
Have you encountered something like this, or do you have any guess how can it be fixed?
Thanks,
Daniel
