Smooth Axis Test

This is a script to help you diagnose axis problems without making a dozen oddly sloping 20mm cubes. It homes your machine, defining home as X-57 Y-57 which puts X0 Y0 roughly in the center of the build platform. It then makes several moves all at a set speed. The moves include a big "plus" shape, an "X" move into the corners (this one seems particularly prone to bad resonances) and then two trips around the Carabiner V2 shape cut and pasted from rapids created by Skeinforge's "comb" setting
