Hi

Can you see what data should be as standard in the motor turning ??( For mach 3)
I have X Y X axis stepper motor 23HS8430

May I suggest that you have a read of the manual as that covers how to determine the steps per  unit.
Next just do a search and you will find how to determine the max velocity and acceleration.
You will also find info in Members Doc's.

Still have problems reply back,

RICH

Where can I find docs about it ??
