Used the Glowforge to make my first automata, of an angry great old one thrashing in the waves. The shaft is a blackwing pencil, which I used as a hexagonal dowel so the cams didn’t slip, and the rest is a combination of medium plywood and acrylic. I found using the acrylic for the follower made a big difference reducing friction.
It would be amazing if the GF software helped in some way with kerf adjustment for parts that need to be joined. Everything in this is press fit, and it takes forever to dial it in correctly.
