If it's a '44 then it never worked correctly. The OP states the laser would "burn slightly" when new. A '44 running 5+ watts will do more than 'slightly' burn wood. :lasergun:
In looking over the laser and driver again, it is more likely a cheaper 445nm like an M140. In several of the photos of the beam it looks more like a MM diode than a SM. I still believe it is a 445nm, but likely a less powerful one than the NUBM44. The driver doesn't look like one that could drive that high a power diode. At $130.00 it is too cheap to be one as well. It could very well have been a 1.5 watt laser to begin with. A look at the diode would answer most questions immediately.
The OP said the driver was pulling 0.6 amps at 5 VDC. That's 3 watts in. That makes me think it is a MM 445nm too.
