The BeagleBone is rapidly becoming a key player in the CNC and (I hope) 3D Printing space. Don't believe me? Just check out the list of 3D, CNC, and motion control capes I threw together. It turned out to be a *LOT* longer than expected! Even better, most of these will work out-of-the-box with my existing MachineKit version of LinuxCNC. Support for the Replicape will need some programming (it requires working I2C and SPI for proper operation, not just twiddling I/O pins), which will probably happen as soon as I can either buy a board or someone sends me one (hint-hint).
If I missed anything, you notice any goofs, or if you have more details on any of the boards (including YouTube "Action Videos" or similar!) please let me know.
