CNC Router

Description

To celebrate the new year the space decided to get a CNC Milling machine.

The idea is to spec out a machine from the openbuilds selection of goodies and profiles to meet our requirements; this turned into a phased deployment of a functional C-Beam machine kit first, and then extending this into a 1000x750mm gantry style machine ASAP.
