Not sure, yesterday i put the dmm on the light sensor and got 25mV on full power, im gonna get a laserbee lpm that you hook to your dmm to check the output power.
It still stops lasing below 6A so i think it needs some more hours or running.
I really love the way you recycle stuff Magus. You turn junk that you have in your basement into an artform, in this case, a case for a laser power supply. Well done
