3d printing!

The start of a gantry 3d printer. The toolhead will move on the X and Y plane and the build platform will move along Z. If it turns out as planned, it'll probably have a build area of around 10"x10"x12". Most (possibly all) of it's structure will be aluminum angles and bars bolted together. I haven't figured out a good way to keep all the joints straight yet but that shouldn't be too hard.
