Just set up Mach3 on a new,(recon), computer and have a problem with the pulse outputs. Driver test exellent. Checked pulses with scope and instead of 5 us pulses with variable frequency I have variable pulse width, ie PWM. This is on X and Y outputs. Also I have the same waveform on the direction pins as well. Is there a setting for this I have overlooked, I know about the spindle PWM setup but I am not using that.
Any ideas?
