    I need some advise on how best to wire my K40's power supply to a Blackbox. Basically I would like to know how I should wire it so that I can still use the potentiometer to set my lasers max power and use the controlling software and the PWM of the Blackbox to adjust the power from there. I have a rough wire diagram I drew showing the LPS wiring from when it was in the K40 which shows what pins the LPS has. I found a wire diagram showing a Xpro to a LPS that is identical to mine but I'm not sure if this wiring would let me use the potentiometer as it was in the K40 (attached to the GND, 0-5v IN, 5v Pins) or if it would be good to wire the LPS to the Blackbox in this manner. Any advise would be most welcome.
