Hi friends, i want to drive stepper motor from parallel port through mach3 software, i connected the step and direction pins to the the driver of stepper motor and configured the mach3 accordingly, but it didn't work. Now to find the trouble i tried to check the pulses from step pin of the parallel port, but no signal found just noise comes. Please anyone help me how can i do it, my problem is that the pulses should come from the pin configured as step pin. If anyone can help then please help me soon, i am in trouble. Help me please please.
