XP 32bit fresh install with only mach installed

A bit of both. 2 steppers (the Y and Z) are connect to the ballscrews and the dual steppers for the X are without.

What is the motor?


Nema 23 4Nm (8 lead type) on the X and Y. The Z is a Nema 23 3Nm.

do you have the dasheet


Have the datasheet from your webshop.

how are you connecting (Series or parallel) and what is the current set to?
Parallel wired and I've tried the current on the default (DIP 1,2,3=ON) and also 3.93A RMS (DIP 1 & 2=ON, 3=OFF)
