how old is your tube

just a couple of months.

have you tryed cleaned your mirrors

I can almost guarantee that it is mirrors out of alignment. It has been happening so frequently for me that I have it down to a science to adjust mirror #2, the one that travels on the Y axis. I’ve also found out that there could be thermal issues as well. When mirrors are cold, the focus seems to change when they are hot. Also, clean your mirror and your laser lens, especially if you don’t use air assist.
