I have finally got my BOB working with mach3 and managed to get the stepper to turn. My set up includes AM882, Nema 23 and a ZP5a-INT BOB. However I have no idea how to go about tuning this stepper and driver config using the dip switches on the driver or on mach3 itself. Please could i get some advise on tuning the motor to allow it to run smoothly. I have added a link below to a video that shows what the motor is turning like at the moment.

Any help would be much appreciated.
