I bought a K40 3 days ago. It worked well for 2 days, it had “power” in it, but 1 day ago the laser tube made a strange sound.
At the end of the laser tube is a metal ring, the plasma draws an arc.
I don’t see a fault on the laser tube.
I cool with distilled water.
THERE IS NO “POWER” IN THE LASER
ENGRAVES VERY WEAKLY AT 60%
Im a beginner, so I have no idea where to start
I have a video, I attached link
Thanx for the help!
