Greetings!
I have a 50Watt EXT that is suddenly having issues. I was doing a pretty heavy job of 1/8 plastic cuts. About half way through, the laser only has about half the power it once did. It's very strange.
I checked alignment of everything and the table is indeed level. I tried different material with the same result.
I fear the tube may be gone/going.
I noticed that the cuts are causing way more..... dusting than normal (residue left behind as dust).
Any ideas?
