Status:
* Linear interpolation machine control complete (Arc support in embryonic state)
* Buffered, non blocking, asynchronous stepping so the rest of the system is free to generate new steps and parse
g-code while the steppers are still steppin'
* GCode interpreter complete
* Basic serial protocol complete
* As of yet completely untested in a real environemnt. Still waiting for my micRo kit from Lumenlab.com

Limitations: Limitations:
* Limited GCode-support. Focus on the kind of GCode produced by CAM tools. Leave human GCoders frustrated. * Limited GCode-support. Focus on the kind of GCode produced by CAM tools. Leave human GCoders frustrated.
