For doing large pieces the Shaper Origin seems like it would be usable but awkward, and not very good for production of large things. I wonder if you could have it on a little self driven sled with omniwheels that would let it go any direction, and then the servos could improve the accuracy of the wheeled movement.
What I really want is a combination of the Glowforge and the Shaper that could cut an unlimited size. The idea that the workpiece should have to fit inside the box is kind of crazy. Maybe a box without a bottom that can be slid over a workpiece if it is too big to fit inside.
