Working Notes

The design creator has made a number of videos available, as well as assorted assembly notes. He also has made control software which should probably be handled separately.

The design is notable for its simplicity. Belts are eliminated. The formed parts are designed to be easily produced in small batches and accept roughness derived from their production. A definite effort has been made to reduce the number and variety of components.
