Experimental Cupcake CNC Sequential Build Platform

This is an experimental concept for a drop-in replacement of the cupcake CNC x-y stage. The idea here is that the y-stage is replaced by a stepper-driven conveyor belt that will move back and forth during build, and then be driven forward to eject the part after the build is complete. So far I don\\\'t have a 3-d printer or lasercutter, so it\\\'s a concept only - but I figured that this was the place for it even during development. I would very much like to hear suggestions for improvements.
