I do a lot of prob building and I can't count the number of times that a simple, low-powered laser cutter would have come in handy. Over the past year, I have been gathering supplies for this project; stepper motors, linear bearings, a laser, and a pine64 to control it all. I've seen tons of tutorials on how to make little ones, but I want to cut 12" by 18" foam/vinyl sheets. There are lots of ways to go. Like belts vs threaded rod. I'd love to see Ben's take on a cutter that size.
