Hi PCW.
The dip's on the drivers have it as needing 1600 (or 25600) pulses for 1 revolution.
In the stepper settings in Lightburn you set the pulses per revolution, so 25600. And I was expecting the same behaviour in LinuxCNC.
You are saying that in LinuxCNC you have to tell it how many microsteps are in 1 regular step? But how do i know how many full steps there are in 1 revolution?
So to what number would I have to change the 1000 then? And what about the step times?

One thing you need to remember is that the PSU have an initial inrush current that is greater than the max current the PSU draws when running.
I went with fuses rather than circuit breakers.
 

Thank you Rob. I have found the following specs on the MDR-100-24 PSU:
