I was about to start a laser job this evening…Got it all setup focused as per normal. Then went to reset the board to reset the zeros… but it did not produce the usual super bright flash. It was much dimmer then usual. And When it looked at the dot it was not focused nearly tight as a few seconds earlier. So I moved it up and the shape is no longer the usual rectangle but round and splotchy.
I checked the Arduino and driver. The Arduino is out putting the proper 0-5 volts. I connected the test load and It was showing 2amps at 100% power.
It seems like it must be the diode but I am in denial… LOL it has many many hours of mirrors on it.
@leo69 what does it sound like to you?
