I am cutting some thick poster board - some even call it chipboard The edges need to be accurate and clean like a jigsaw puzzle. When I cut through on a honeycomb I get some back flash occasionally scorching the cardboard. I played with speed and power and frequency.
I was wondering what people use to absorb laser energy after it occasionally cuts through the material.. I tried a couple different ceramic tiles, laminant flooring, plywood all with varying success. A pegboard will not do as the pieces fall sometimes going underneath the next cut. The cardboard must be supported all throughout.
The material must be larger 24" x 18", and flat. Will a marble or granite work as the laser just has to cut through cardboard, does color and texture affect?
Anyone experimented?
