Thanks h@ro,
I am new to mach3 software and actually i want to drive the motor using pendant function at this stage, i don't know how to do this. If you please give me a simple procedure to drive a stepper motor using pendant function, it will be useful for me. i have designed the stepper driver myself and its working properly. but the problem is actually to drive the motor from parallel port using mach3, mach3 is the problem. I connected the driver step pin and direction pin to parallel port pin 2 and pin 25, but no response. obviously the problem is in my mach3 settings. please help, i am waiting
