I am new writing a question, but I always read the forum. First, I want to thank everyone that contributes sharing experiences and knowledge to this place.

I have tried to take some pics to show my doubts. the problem begins when I am preparing the stepmotor to move around the axis. It makes tiny movements, like fast and little increments. All 4 stepdrivers are set to Vref= 0.5V.

I need to use full step. So I pulled out all jumpers in x, y, z axis.

Fullstep
Pitch = 4mm
Unit per step = (200/4) = 50

I don´t know if the problem lies in the formula, or acceleration, or speed. I have tested the drivers, all working properly.
