Fingers crossed it'll cut ally

Ok disregard that, just had another look. It should be simple to get the servo tester connected.

:idea: Here's a step by step guide.

1. Remove the potentiometer, or just desolder the pin connected to R32.
2. Solder a wire to the pin of R32 that was connected to the potentiometer.
3. Connect the other end of that wire to the chosen output pin on the parallel port...say pin 14.
4. Solder a wire to the negative of the circuit board, e.g. pin labled '-' on connector JIN, and connect it to any ground pin on the parallel port.
5. Set PWM frequency in mach3 to something high, like 1000.
6. Under Config-->Spindle Pulleys set max speed to the max RPM of your motor.
7. Cross fingers...it should work as normal with the rpm show in mach3 corresponding correctly.
