I am still learning a lot about using the laser, and I think it is funny how much I struggle with it compared to 3D printing. I think the hardest part is using an inconsistent material like wood compared to a very consistent filament. I have struggled with 1/4" plywood that has internal inconsistencies, while a solid 3/4" board is easy to cut through. I think I'm just using the wrong brands of plywood, and I need to find a source of wood that is made for laser cutting.

Yes I've been slowly trying to build out my lightburn library, so I'll have to cover it when I get it all nailed down. That is weird that we would get such different results. I'm not an expert on how these lasers work or what could cause things to be that differently focused.
