Thanks for your encouraging words!
The problem was related to misalignment of the Arm Bottom and friction between the inner surface of the Arm Top and the Arm Bottom and the GT2 belt associated with Axis 2
Exactly, and thanks for provdiding a way to fix that. On the future 3D printed parts that we produce (we’ll also update the STL soon on github), we have solved this issue by allowing more space between the belt and the printed parts.
The misalignment is also another problem and mostly due to imperfections in 3D printed parts + torsion spring. We have worked on the torsion spring to make it better and find a supplier that can produce torsion spring with a lower error margin.
