As a proof of concept, it performs...adequately. The frame itself seems fine, but some of the parts that are under belt tension look like they are deforming slightly over time. I used ABS; perhaps PetG would be a better material, or the parts should be reworked. This is not an easy project to troubleshoot, and the wiring is still giving me fits. A proper cable chain arrangement is eluding me and this project is low priority at this time.

The printer is intended for fast & dirty prototyping, using a big (1mm) nozzle. I would not expect to use it for fine detail. In retrospect, I should have made it a bit smaller, like 12x12x12 inches. Too late now... ;-)
