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. Profounddevices Videos on YouTube

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.

Tooling

Description of tooling requirements.

you will need 2 pliers or a pair of pliers with socket wrench, tape, knife or extractor knife, and super glue to glue the tubing onto motor axis. for the redesigned version that has pull-chain you will also need a file to file down the x and y axis to fit into the geared adapter that is slotted for washers or a 1/10 nut. this prevents nut from slipping.

also for Assembly of axises, to bushings/spacers. it is a good idea to file the space for the spaces, and leave enough room, to place hot glue from a glue gun between them. and for the x and z axis with extruder mount it is a good idea not to have it more tight then it needs to be otherwise it will drag. i would sand the top a little bit, and place hot glue in between the bushings while the parts are in place. this ensures simple alignment, and little slop room. I will post more videos soon, but this model is retiring soon.


if you are interested in a reprap and have not started, this design is now old. there is another user that is doing a simple reprap that is called Prusa Mendel. It uses many similar design setups such as 2 motors for z axis, bushing on axis's , and it has much better documentation, and formal recommendation for use of cnc components and drivers. I think with the right frame of mind and a good size garage you could make that one for around 250$ us. currency. watch my cnc videos or use my software g runner to test setup. www.profounddevices.com 12/6/2010
