I finally received a new SSR relay and now have my spindle up and running great thanks to your help.
I am so very close, but I cannot for the life of me understand why my PWM voltage will not change and is a constant 5v out of my board. I have the PWM set to be Port 1 pin 17. I have gone over mach3 manual 5 times but I am missing something easy, I am sure. Would you just glimpse at these settings and see if something jumps out at you?? The white wire in the pic is my PWM and is Port 1 pin 17 (this is just temp wiring). Shouldn't that voltage change as I change the speed in Mach?
