I have a 80 watts Orion Tech (Chinese) laser machine. It was bought on Amazon. It has worked fine, but last night I saw the laser beam doing some tumbling dance near the output coupling. Here is the video:
So far, all the wiring connections seem to be well made. My chiller is filled with distilled water.
When I took the video, the machine was cutting at 19 mAmps, so I don’t think it would be a low power problem.
I’ve been getting jagged cuts lately. Not too bad, but you can certainly feel cuts are not smooth when you slide our finger on the cut edge.
Any advice or thought on the posible cause?
