BBP, means BeagleBone 3D Printer, based on AM335x Cortext-A8 chip, running Linux or even Android. It will be the next generation of 3d printer controller, making 3d printer at least 2x faster than ever.

The BBP board is designed for machine control in mind, it can be used for 3D Printers, (like repraps, xyz type, H-Bot/CoreXY type machines), Laser cutters, CNC Mills, Pick and place and other small-sized CNC machines.
