Stalling stepper because your motor tuning is too agressive?

Reduce your velocity and accel 50% and try again.

Are you using a PSU that delivers enough voltage at peak demand?
My PSU is only rated at the stepper voltage  - it's what came with the machine and is probably what's required with the control box which also came with the machine.
When I replace the controller I'll be using a higher curent and voltage PSU as the new stepper drivers I'll be using control current to the motor,
