Mini-router is a small CNC robot that uses Dremel as a tool. It is also a test to see whether Contraptor offers sufficient stiffness to do hobby-level CNC work. A satisfactory criteria would be the ability to mill soft sheet materials (plywood, MDF, HDPE, acrylic) with 0.01" accuracy.

A test mini-router was built using the old design of linear motion components, and a couple of milling tests were done on plywood and HDPE.

Second version has been assembled, it does work but the movement speeds do not exceed 20IPM, in other words it's pretty slow. The video on the right is sped up 16 times.

A belt driven design is in progress.
