I have a mill that I am trying to convert to use the PMDX-126 and 107 for control with Mach III. The machine is all wired and I think I have the DIP switches in the correct position. When I enter the test mode on the 107 it will spin the spindle however I have no control with Mach III. I have done some searching on the Mach forum as well as here and found a general setup guide that referred to using pin 16 port 1 as what I will call a spindle drive however I can't seem to figure out how to get that from the 126 to the 107 board. I am wondering how I can make it all come together and/or if I have to use a PWM setup to make my spindle work.
