Laser cutting plywood

Hi! I really hope someone can help me! I have tried for months to cut through plywood with the 1600 laser but no luck. Well actually I did make it once but it took one hour to cut a 15mm dia circle :joy: I have seen so many of you complete laser cutting after laser cutting and I have tried all your advice but still I have no chance getting through. I am no expert using laser, I usually use it to engrave buttons but I really would like to cut through plywood so I can make other things :slight_smile: pls help me!! :slight_smile: oh and yes, since I still haven’t recieved sm2 I use the sm1 and I have tried in snapmakerjs and luban:)
