last night i was doing a test cut on my chinese 60w c02. this thing has been a nightmare from the word go, but after 4 or 5 tries aligning it i finally got it working. last night i was running a job and the laser suddenly stopped firing. the gantry kept moving as normal, just no cuts. i have tested everything from the ac inlet to all the switches. the psu is getting power. the light in on and the fan is turning, but i don't have the equipment to test the output. if it were a faulty tube, wouldn't the power decline somewhat gradually over time?
i was running the cooling unit of course, everything is set up properly. like i said, lasr was firing one second, and not firing the next.
when i hit the pulse button it beeps but of course no laser pulse. i held a piece of paper in front of the window and it did not so much as darken.
has anyone had a similar experience? what was the problem if so?
