I rather like the idea of using Gcode since it's so ubiquitous in the world of CNC. Seems like some of the modern microcontrollers ought to have more than enough power to interpret Gcode and drive some stepper motors or servos. It has struck me a number of times that in virtually everything I have ever built with a microcontroller, even the lowest end ones end up spending 90% of their time in delay loops.
