Sorry, i would also like a wiring diagram to be honest. I found that the L terminal was a bit loose but i can’t make it any better, btw if mine does operate by 5V being 0% and a voltage drop causes the laser to fire then could it losing electrical connection cause the laser to fire at 100%?
I’m considering just ordering another power supply, maybe 2, the 5V signal has me confused tho.
Found this from manufacturer
Would the test button tell me much?
