I think polygonalhell was working on printer control with a beagle bone
He was having purulence with the GPU IP. I got quickly lost reading his blog post, to advanced for my simple mind. Hopefully he, or somebody else succeeds. He was trying to have an all in one slicer and printer. I guess by the time I scrounge up a budget and devise a design for my next printer, this controller work might be done
