SOLVED: I have a volt meter across my Laser power POT and when I press the laser enable button the voltage setting drops 2 tenths of a volt. I’ve put a meter across the 5V(left and right side of the POT) and don’t see any change in voltage( only showing one decimal place though). When I measure from Ground( right side) to center I see a drop in voltage. When I measure from center to 5V(left side) I also see a drop when the enable button is pushed.
This tells me either 5V out of the PS is dropping slightly or the center point is being loaded.
Hmm, maybe I have to high a resistance(10K) of the POT…
SOLUTION: I installed a 1K 2W 10 turn POT. To get by with the 10K POT I’d put 2 1K ohm resistors on the POT and that stabilized the voltage. I found my original and saw it was a 1K… Then while searching these forums I saw 5K and 10K mentioned and probably why I put in a new 10K. So get close to a 1K POT and 10K is just too high.
