I second what @Jules said for the cut. I’m working with Woodpeckers Baltic Birch 1/8 and 1/4 (more often the 1/8). I need to revisit my 1/4" engrave settings now that I’ve done a few more jobs on the thinner ply. You’ll be able to get away with a faster cut if the board is absolutely flat and flush with the honeycomb, but here’s what I have in my notes that you could toy with.
