Mechanism

The mechanism is based in the COREXY project. CoreXY provides a fundamental building block of many computerized fabrication tools - cartesian motion - in a simple and adaptable format.
Three main concepts of the COREXY are:
Fast: We believe in speed. COREXY (mostly) parallel kinematics mean that the motors, typically the largest source of inertia on a DIY-grade stage, are stationary. This permits rapid accelerations.
Simple:  COREXY can be implemented with only three structural plates, all of which can nest during fabrication.
Flexible: Whether your medium is fabric or aluminum, the principle behind COREXY permits motion stages to be rendered in a variety of materials and a wide range of sizes.
