progress. But I still need some way to spin the blue/grey Arrays from the edge (aka the "Frisbee Drive" I've mentioned before).
This view shows how the existing grey arms will unfortunately not move/spin past the 9 remaining Array axes that have yet to be placed on the [yellow/black on red] feet.
There's a physical/mechanical alternative, although I don't want to do it because it wouldn't be nearly as neat. It would also compromise stability and make the machine more than 4x in diameter... I'd have to create 3 more sets of 3 Arrays each and place each set [more than 2x Distance from Center] than the previous set of Arrays. Doing so would prevent all arms from hitting any axes.
