I have a 60W 4060, RUIDA RDC6442G, I ran it yesterday doing some engraving that was about an hour straight that turned out great. I have a water chiller that was working and kept the temp consistent. I have a Milliamp gauge as well so I generally keep the laser in safe ranges to not over work the laser. Bought the laser new direct from China 2 years ago. I had to replace the Power Supply last year. Overall hobby type usage on it and the tub. Yesterdays 1 hour session is probably the longest at any one time.
Today I went to do some more engraving. Machine acts as though its working with the movements, but laser isn’t firing. Milliamp Gauge is showing power variations, so it seems power is working. When I noticed it wasn’t firing, I shut it down and rebooted the machine and everything. Same results. I then tried the Pulse button on the controller and still no dice.
It’s not at all acting like it did when the Power Supply stopped working. So I am thinking maybe the Tube is shot… which is odd with such limited use. But I am hoping it isn’t. Can anyone recommend anything that may help in my situation? Much appreciated!
