Hello, I have a cheap Chinese laser 60w 500x700, it was not cutting well so I up graded to a 80w power supply and tube, now it will work good but the tude is firing all the time, I have to turn the laser switch off to kill power to the power supply to get it to stop. Any ideas on what I have out of wack? thanks Paul

Sounds like the signal wire for the laser is hooked to the wrong line. Therefore, always "on." When I switched power supplies, I had to rewire the connector going into the power supply as it was just a bit different than the old one. Did you have to change the wires on yours?
