Camtech Laser L5 engraving issue

[Miguel Pinho]

Hello
My L5 Laser Master is engraving a little bit blurred ( notice the "S" letter on the attached image).
Also, is making a weird lined engraving.
Can someone tell me what is causing this problem?

Thanks

Regards

Loose optics... loose belt/gear...

Make sure the gears are not slipping or moving back and forth on the axle (often from a loose grub screw). Then check every optic mount to make sure they're solid.
