Hi everyone,
I want to driver the stepper motor from parallel port of PC using mach3 software, i did the settings according to the tutorial, now i want to see the step pulses on oscilloscope, but it gives constant 3.3V DC, although it should give some clock pulses on step pin. so what may be the problem? Help Please
