View Full Version : china 40W Co2 laser stopped cutting

So my little el cheapo laser cutter has packed up on me and Im not sure of the best/safet way to test it.

It all powers up, motors home and the power meter returns to the last setting but the laser wont work off the test button or under pc control.

The led below the test button is permanently on.

What's the best way to test the HT side or does it sound like a dead psu?
