The mini CNC is coming along very nicely. Friday was first light, and over the coming weeks, the forward and inverse kinematics will be fine tuned. Our goal is to be taking XYZ moves coming in, and process into the ABZ polar coordinate system. The spindles shown are not the final ones, however, as these have been discontinued by NSK. The search continues for an inexpensive air driven spindle of greater than 150krpm.
