Hey everyone. I just got this cloudray lens recently (a few weeks back), and a few days back i heard almost a crackling noise from the machine but couldnt pin point it. 80w Cloudray laser at about 10-15% power. I did a few other cuts and was ok. Then the second mirror bracket came loose and I had to readjust and reallign it. I did another cut and looked completely out of focus. Line is round but really thick. Not the very fine line it was doing before.
I opened it up to clean it and see it like this.
Is this an issue with the lens itself or something else I should be looking at? I never had issues with the older cheaper lens that was on the machine rated for 40w.
