Using a 60W Chinese laser with a Ruida controller that has functioned well since I got it. Using a chuck rotary attachment that has also worked quite well. Upgraded to the new version of Lightburn yesterday.
Now I am having a serious problem with X axis errors in alignment. Parts of the image etch offset to other parts of the image along the x axis. The offset appears to be completely random. I did a test on a clear glass tube and it came out perfect. Went back to the blank I wanted to etch and the offset problem persisted. One photo shows the binary numbers in line like they are supposed to be. The other two photos show the offset problem. For the life of me I cannot imagine what could cause this issue along the X axis. I have had this laser for about three months and have not seen this problem before.
