Stepconf works but Axis dont move - Speed Error

You are right, i meant less steps/revision is lower torque.

But there isnt a mechanical or electical problem, it is the software or step pulse lenght!!!

Z is a leadscrew without ball bearings, but it doesnt matter cause i can drive it with fully 20khz in stepconf, and mechanic would go even faster.

I will try to measure the pulses with an oscilloscope later, maybe stepconf and axis use different pulse lenghts.
