Chocolate 3D Printer using Probotix FireBall V90 CNC Platform

This remix uses RichRap's Universal Paste Extruder files, and is meant to operate with a FireBall CNC Platform. A pressure sensor is mounted in the end-cap to act as a limit switch to interrupt the circuit (as a safety feature) when the pressure exceeds a certain threshold, indicating either there is a clump of chocolate or it ran out of chocolate.
