I'm banging my head against the wall. I've followed the Pokeys57CNC/Mach4 guide and feel like I've got all the settings correct, but I'm not getting any voltage out of pin 17 to control the speed of the spindle through the VFD. In the Pokeys config > miscellaneous, the 'Enable PWM outputs' box is checked (freq set to 20000 Hz), the pin 17 enable box is checked with default (%) set at 0, and the Spindle output dropdown is set to Pin 17 (set to 0 when OFF is checked). Is there anything else I need to do to have Mach4 tell the Pokeys57CNC to send voltage through pin 17?
