I’m knee deep in software development for a couple of motion control projects, and have had the feeling that I’ve been re-inventing the wheel for a while. Well, I wish I would have found grbl sooner. It appears to be a mostly complete implementation of the g-code standard, written to run on an Atmega328-based Arduino.

Which, if you prefer English, means that it is a program that runs on everyone’s favorite easy-to-use microcontroller, that can precisely control up to 3 stepper motors at a time, using a standard protocol that most computer automated manufacturing programs can export. So, you can use it to control a low-cost milling machine, 3d printer, or perhaps biological specimen observation station. Cool! [thanks, Marty!]
