This machine is close to being able to mill circuitboards. For the first try, the stiffness of the end effector wrt sideways force seems to be the limiting factor, rather than the xy stiffness. Next step: a better arrangement of z-stage and full incorporation of the z-motion into the software.

### Small-excursion z-axis design:
A cam translates the spindle by flexing the beam a few mm. Total excursion at the spindle is about +/- 2 mm.
