Thanks for the reply Jazz, it was a phase error as i was testing with nothing connected, whilst at the same time trying to work out the setting for the enable on the drive. Once i hooked up a stepper (or disabled phase error checking temporary) it worked a treat. Got to say the 4nm steppers are very strong.

Ive got the cabinet almost finished, just got to do the controls for the CNCs front panel and then the basic wiring on the machine putting the plugs on the steppers ect and it should be done :D.

Thanks again
