Spindle Control Pins
« on: May 14, 2010, 08:40:44 PM »
Is there a way to prevent Mach 2/3 from sending a PWM signal to the spindle?  I am using a relay that will die if it is being constantly switched on and off by a PWM signal.  I only want the relay to turn on or off, thus a simple high or low should come from the step pin.  The motor has its own speed control.

Uh, yes just don't configure the spindle as PWM control :) Then set up the correct output to use for M3 (spindle on) for the relay. I would suggest taking a look at the Mach manual to get a good overview of how to configure things.
