I’m quite new with Lasercutter, having a 100W (120W nominal) with Ruida. I’m experimenting with all kinds of material, but having a lot of problems with cutting birch plywood. Mostly it cuts very well but on many areas not cutting through. Sometimes I can cut the rest from the backside, but very often the plywood sheet is for the trash.
I have read that this might be due to areas with more glue in the wood, but even cutting with more power doesn’t do the job well. A bit better, but still not good.
Any hints how to fix this problem ?
