Also , you mentioned that the laser is coming on. Hot enough to burn things after it’s focused? If so then I would repeat the tuning with a different meter. It’s possible a cheap meter won’t read the current level past a certain point. I had one that wouldn’t go past 1.4amps and then I used my other meter and found I was actually at 1.9amps and had to adjust down.
