Hello to all Master in CNC.

May I ask your help about my Mach3 (photo attached) we don't have problem in XYZ Axis our problem only is we can't measure or no voltage output in OUTPUT 1-4 where in the connection is for Spindle motor.

The first step I measured the voltage across the IC and connect to (it seen like Diode) and we measured 7v , but to measure in terminal wire no voltage output.
I hope you can give advice how to troubleshoot this.

Thanks

Here is the wiring diagram for that card. You will probably not get reading until you are running a program and the output becomes active when the program calls for the spindle to start or stop. This is how I have wired this card in the past and it does work.
