Contraptor

Contraptor is a DIY open source construction set for experimental personal fabrication, desktop manufacturing, prototyping and bootstrapping. Various сartesian robots can be assembled from Contraptor and used as a prototyping platform for projects such as XY plotter, mini CNC machine, 3D printer etc. Contraptor uses several developments of the Reprap project - specifically, Stepper Motor Driver boards v1.x and Arduino GCode Interpreter.

Contraptor-based RepStrap

(Does this have a catchy name yet, like other RepStraps?)

An effort is underway to build a Repstrap and/or Milling/Repstrap hybrid on the Contraptor platform, most likely using mini CNC contraption as a base: http://www.contraptor.org/mini-cnc

• Mini CNC case study [1]
• Contraptor mini-cnc with Reprap firmware.[2] (has this been reported upstream?)
• Contraptor Mini-CNC Build log.[3]
• Super mini bootstrap CNC [4] discusses building a one CNC machine mostly out of Contraptor parts that is designed to drill all the holes needed to convert aluminum angle into more Contraptor parts -- does this meet the definition of a RepRap, not merely a RepStrap?
