While I'm going the Beaglebone Black route, my end objective is a stand-alone 3D Printer system. The $45 BBB with a WiFi connection, the Printer Cape, and a 4.3" TFT LCD touch display, will fit in the space of my present SmoothieBoard controller. Initially I will use the WiFi link to import G Code files, but I hope later to do the STL file to G Code conversion on board. No PC required.
The two on-board PRU processors solve the problem of doing real time with most of the code running on a Linux operating system.
