Running Mach 3
Mach3 usb interface board
Huanyang 110V VFD
24v relay

M3 =  Relay clicks, the FWD light turns solid, but spindle does not turn unless I hit the speed arrow, and then the spindle starts.

I wired the VFD according to the diagram on the BuildYourCNC page, but I can't seem to control speed.

Than I got a "pwm bumped to minimum setting" and the relay does not click anymore.

I've been "building" this machine for 7 or 8 years now, on and off. It worked for a while with an Arduino board and a free gcode sender, turning the spindle on manually, but I got the idea to add a 4th axis and it's been a nightmare ever since.

Have you specified a speed with the    S   gcode?

Haven't run code yet, just trying to get the mechanics to work first.
