Short answer: can't do it now.

Medium answer: there is only support for XYZ axes in the NC interpreter.
There is support for up to 6 axes after the kinematics calculations, so
we are able to drive that small cable-based Stewart Platform with 6
cables. All 6 move when the tool tip moves on a line. However, the
platform always stays level and doesn't rotate: only XYZ can be
specified.

We're working on this. No good estimate for when we'll be finished.
Summer?
