Does anyone have a schematic for a 110VDC 20A speed controller that is compatable with Mach3 or where I can buy one for under $50. Now I'm using a Nordictrack treadmill controller and don't know how to connect it to Mach3. Ben

Now I have a controller (U-MC-2100-WA) that accepts a pwm signal. How do I set the pwm output pin. The docs talk
about everything but how to set the pin number. Then I assume that I put that number in the Port & Pins-Motor Outputs
-"step pin #" box for A axis(unused). A axis step on the BOB will be connected to the pwm input pin of the controller. Ben

Use the spindle not the a axis. Look for spindle in motor outputs and in spindle setup both under ports and pins.

Thanks Don. The problem is I have a Sound Logic BOB and it dosn't have a spindle output connection. I thought I could send the pwm signal through the Aaxis step connector since I don't use Aaxis. I have mach3 running the spindle using M3 and shutting down with M5 but no pmw. I enabled the Spindle in Ports & Pins>Motor Outputs, step pin #16 ,dir 0 and Aaxis step pin #16 dir 0. The stuff in Ports & Pins>Spindle Setup>Motor Contron Use Spindle and pwm checked, Freq=100 min=10. Ben
