Hi there, I'm interested in this (old) topic, I almost have the same issue. The laser worked fine for an entire session of one hour then two days later and few minutes ON it did the same : D4 is flashing but no more laser. When the led is flashing I noticed that the fan of the laser is moving a tiny bit. im on Mac but I tried with a pc also, same result.. I would go for a burnt board but I'm really not sure.. Doesn't someone have some clues on it? thanks!
