 This implements the [RCT Gantries](https://gitlab.cba.mit.edu/jakeread/rctgantries) project for axis design, and the [AutomataKit](https://gitlab.cba.mit.edu/jakeread/automatakit) project for controls. 
 
 The machine has a bed size of ```410 x 820 x 40mm (16.15 x 32.30 x 1.5")``` - the machine itself is 740 x 1100 x 430mm, and weighs about 20kg. It fits on one 4x8' sheet of HDPE, that we cut on our shopbot with a 1/8" single-flute o-cutter. The whole thing machines in about 2.5 hours, and goes together in a few afternoons or less.
