Can any one please give me some guidance. New to lasering and the forum. I have just bought a used Epilog 24TT. Had it for nearly three weeks. On Friday eve I was rastering some acrylic when it started to miss out some bits of the image text I was engraving. Checked all connextions, resent image, restarted Corel draw and PC. RRestarted laser.Still no change.
I tried repeating the same job to see if the same bits were missing. It missed out bits at random. Then on the 7th or there about time it worked OK. Tried the rotary fixture, 3 glasses came out OK the the next ones missing bits again.

Any one out there had the same problem? Any suggestions please. Going nuts at the moment. Got jobs to do and a dodgey laser. Cant afford to mess up more work.

Thanks,
Pete T
