Hello guys,

I have recently purchased a new CNC router "kit" and am at the stage of getting the stepper motors to run.

I have them setup in MACH3, but when I try and jog the axis around using the keyboard the motors move but pretty slowly.

I've tried tweaking all sorts of settings in the motor tuning config, but cant seem to get the axis to pyhsically move past around 1m/min - even though the output screen on MACH3 says they should be up to 4m/min!

The only description I have of the stepper motors are "425oz", which doesn't mean a lot to me.
My breakout board is this>>>

Stepper motor drivers are >>>

Can anyone help???

Thanks
