Ground Control Version 0.64

This week we really started getting feedback from our beta testers resulting in an improved calibration system, support for the z-axis, support to render gcode generated with the grbl-generic post processor in Fusion 360, support for setting the encoder resolution and sprocket size for home built machines, a proper version numbering system, a re-organized UI, a 'stop' button when prompted for action, and numerous bug fixes.
