I recently received my 50w laser engraver, after getting it set up it ran perfect for 3 days then the laser stopped firing. The tube in the back was lighting up (purple) and the head was moving with the program but no laser was firing into the mirrors. Tonight I opened the back and hit the test button, the connection from the board to the tube was arcing against the side of the machine. I have contacted Ten-High but do not have much faith in a quick response.

Anyone have any incites?
