Hey, wow, glad to see someone actually made a dollo and got it working. I found the dollo through the reprap wiki a few months ago and was initially disappointing at the lack of available information on it. Despite this, I'm still fascinated by the design and would like to move forward in making one this summer. Any advice on doing so? Should I even bother with the unique z-axis design or try for the normal threaded rod initially? Any advice on 3d printing services to print the parts rather than printing them on the school's printer? What motors would be best to use? I hope someone can help me out here. . .
