How about the Smoothie board?
It's open SW and HW, the developers seem very capable, and they are currently working on support for 6DOF, shipping boards now with 5-stepper support. Actually, they say their system is powerful enough to handle many more DOFs, using off-board stepper drivers, which could be useful for multi-color extruders.

They've finished shipping their Kickstarter promises now, so the boards are for sale to the public.
I mentioned the sextupteron to them, and they're interested...
