Hey Gang, All of a sudden, my 10w Creality CR Laser Falcon SE is not burning properly. It’s “missing” areas of the burn. I’ve made no changes in Lightburn but as you can see from the image example and the screenshot from LB, it’s missing. I’ve tightened the belts thinking that could be the problem. Any other ideas? (After doing some Googleing, is it belts?) Burned example
