Hey Guys, I am pretty new to lasers, and am more of the graphics guy behind our operation rather than the technical guy. My tech guy is in prison, story for another day, so I am here seeking some help.

I was using my laser last Thursday, and everything was great. Shut it down and left town for the weekend. When I got back today, something seems to be way out of whack. If I draw a 10mm square in EZCad, the laser lights it at about 160mm (give or take). Not sure how/why this would have happened. Been using it for over a year with no issues. Any ideas?
