Hi Derrick,
Perhaps you could perform this simple test…
Remove the red wire (connected to LPT Pin 7) from your laser PSU. With the Pot set to < ¼ power level, switch on the system – does the laser fire continuously ??
Measure the voltage between the “L” terminal and the “G” terminal on your PSU (with the system powered up and the red wire still disconnected) is it 5 Volts ??
