Re:Re: I'm impressed. Anyone want to write the G-Code for this?

I don't see the complication in this. It looks like a series of
circular pocket routines stepped down in Z and scaled in X and Y. The
program is only for a single side and then you just flip your block
and then rerun the program 5 more times. We have a similar project on
our web page that we use for our CNC classes. Our cube is a caged
cube where the center is cut free and rattles around within the cage
but will not come out of it. The G code program is also available on
our page for downloading along with set up info.

Everyone is welcome to try it
