Here are my goals:
Crack the root password.
Add some monitoring tools to decode how to interface with the cape board
Work to enable marlin control software with the printer.
Maybe throw my 'scope on the interfaces.
This would allow me/us to reuse the hardware as is...maybe just swap out the beaglebone black....

I may as a side try to use some off the shelf 3d printer hardware. I have a one-up from some other also defunct company that I might try to use that controller in my Pegasus.
