Has anyone successfully cut ½" plywood? I tested with pine plywood. Started quite a few fires in my testing and finally got a cut through that did not start on fire. However, the piece that I cut out was completely charred for the bottom ¼", to the point where it crumbled out. The suggested settings of 100/5/3 made it about half way through.

The internet claims baltic birch or balsa plywood would work better. Can anyone confirm they have cut ½" plywood, and what settings they used?
