   *Upgrade electronics to a 4-axis capable board so we can use the 4th axis (should probably also get an appropriate chuck & tail stock as well). Something like a TinyG or Smoothie-compatible ARM solution would work well.   *Upgrade electronics to a 4-axis capable board so we can use the 4th axis (should probably also get an appropriate chuck & tail stock as well).

 Zeroing: In bCNC, use the arrow keys to move X&Y, and Page Up/Page Down to move Z. You can set the step size in the software - 1mm is good for big moves, and .1mm when closing in on zero. Get your endmill to within a few thousandths of the material (use a sheet of paper as a feeler gauge, and you're there when moving it is "​tight"​). Click "reset zero" and the work position will be set to zero. In Easel, the procedure is similar, but pgup/down don't work- just click the buttons. Zeroing: In bCNC, use the arrow keys to move X&Y, and Page Up/Page Down to move Z.
