Goal: Create a simple prototype of a two dimensional cutting machine

To get started with our multiple dimension mill project we will make a simple model of a simple XY milling machine. This simple machine works much like an x-y plotter or the laser cutter with which you are familiar.

Here are the materials we'll use. Our goal is to create a model of say 6 to 8 inches square that allows for a cutting/drawing device to move in two dimensions. We won't worry about motors to drive it, just the way of permitting and guiding motion in two dimensions. You an experiment with single vs. double rails, rolling vs. sliding, single fixed endpoints vs. dual, etc. The goal of the exercise is to become more comfortable with the challenges of two dimensional motion.
