Yes, I have printed quite a bit with it. It works great. My last version of the prusa had the linear bearings and the same belts and pulleys, so it was doing a great job. In fact, my last prusa printed all the parts for this before I disassembled it to make this version. So the print quality is about the same as the fine tuned prusa. The big advantage to this is the compact size, light weight, and portability. It looks good, I always thought the threaded rods were a little crude. Also the extruder is very accessible. The quick release extruder body for the Makergear extruder is a big improvement, I will try to post that design tonight.
