Great job! Now about the aluminum extruder, where can I get one of those?
I have to say I have been a doubter about the Rostock printer capabilities.
the print quality I see here really is a compelling argument that it is indeed
a very good design. I am particularly interested in the higher z dimension prints.
the size of the print and the level of detail are pretty impressive for a non-cartesian design. I am pleasantly surprised. Good job!
The positional accuracy can be quite
good if attention is paid to the geometry and size of drive pulleys.
The largest issue is backlash in the rod ends. This can be
compensated for by applying preload in the direction of the
connecting rods with a total magnitude in the range of two times the
mass of the end effector.

Nice Work! I am Starting to plane one, Base on Makerslide. Do you have a picture of the link part to the belt?
I uploaded an .stl file and the best cell phone pic i could get. The belt is overlapped, teeth locking together, forming the proper length and wrapped with wire. The spliced section is slid into the slot in the part and held in place by the tension of the belt.
