Inspiration/motivation for this project was two fold: CoreXY techniques for cartesian
motion and Modular Single Axes MTM both from previous version of the class.

CoreXY

Ilan Moyer implemented a waterjet aluminum version of his corexy system. Low
profile, most parallel dynamics, fixed stepper motors.

Modular MTM

Nadya Peek and James Coleman worked modular machines that use single axis as stages.
This work actually started as stages constructed out of aluminium and polymetal, and then
developed into cardboard stages for easy and quick prototyping.

The Merging the Two!

Implementations I have seen of single axis linear cardboard stages seemed to all
start with coupling two stages to get cartesian motion. Even all four teams last
semester in How To Make Almost Anything started off with this. My group in particular
had difficulty with this approach because the thickness of two stages made it difficult
to fit in a small area

Cue, CoreXY, which is a lower profile cartesian implementation. Rather than using
single axis stages, stages can be dual axis. With using CoreXY as a stage, may different
configurations of machines can be built.

The idea is to use various two axis plates as builders.

Some possible configurations

4 axis milling (3 axis, plus rotating the plate)

Slash-bot type control, with independent stage control

Pseudo 5-axis, where each wall can rotate the base in its normal direction
