Hello,
I recently bought a laser machine, but I have not been able to use it since.
The laser tube is new, the mirrors are clean, the water cooling is fine, no bubbles. The power supply works, but the laser signal on the power supply is: off. The laser beam does not reach the workpiece.
What could be the problem or the solution?
Thank you for your help.
