Mach 4 is not triggering PWM pin 17 on Pokeys57CNC. I am able to get it to work through the Pokeys app but not Mach 4. I've made all of the setting changes prescribed in the manual.

I will check with the developer of the board and show the response on this FAQ. Additional Information: The response from the developer: Are you referring to using Pin 17 for the spindle speed control? Make sure that you set the desired spindle speed in Mach4 by executing S1000 in the MDI or the G-code.
