Hello everyone,
I have the K-40 laser for a year and a few days ago it started to scan lines and produce errors in the engraving. What can happen? What maintenance can be done to the laser machine?

Probably need to check for loose belts, mirrors or lens. Also check the pulley set screws on the motor shafts.

My belts were very loose, and optical sensor did not line up well…
