I have an Universal M300. I went to engrave a job and didn't engrave. I contacted Universal and they said that I needed a new tube. I installed the tube and still having the same problem. When I turn the power way up, it will lightly engraved.

It was suggested that I need a beam alignment - trying to do the alignment, and I can't get the laser to burn thru the tape.

Just wondering if anybody has had this problem before?
