The Wikipedia: BeagleBone Black is $18+ Linux computer -- 1 GHz ARM Cortex-A8, 512 MB DRAM, Ethernet, etc. Sone versions,, are sold without HDMI, USB, less bulk But these vendors don't supply design files, as they are required

Replicape and BeagleBone

The Replicape includes all the electronics necessary to turn the BeagleBone Black into a dual-extruder RepRap controller: 5 DRV8825 stepper drivers, etc.

(It is analogous to the way the RepRap Arduino Mega Pololu Shield (RAMPS) includes all the electronics necessary to turn a Arduino Mega into a dual-extruder RepRap controller).

The Replicape was apparently originally designed for the thing-printer (formerly HipsterBot), but it should work with most RepRap hardware.

Other 3D printer capes for BeagleBone

A two layer through hole [RAMPS] derivative would be easily designable.

Apparently several other people have built 3D printer capes or other CNC capes for the BeagleBone. "An unofficial list of various 3D Printer, CNC, and motion control related capes".

Other 32-bit 3D printer controllers

Vaporware Electronics lists many other 32-bit processors and boards designed around them that people are considering for 3D printer control.
