Im trying to sort out several issues with our laser.
One is poor quality engraving on the far side from mirror two which i should get by adjusting and testing.
My other gripe is that circles I cut have a small lip where the start/stop position is.
I think the X axis belt may be the culprit, however I have no information on how tight the belt should be.
I have a proper tension device that are used at work for huge V-belts.
