EMC 2 Arduino is a small collection of files intended to allow a person with an Arduino Mega2560 (or UNO), an old USB enabled computer and a free copy of LinuxCNC to begin building their very own CNC machine cheaply and quickly with a variety of components, ranging from low-end inexpensive (even salvaged) components such as old steppers and computer parts to high-end linear servos.
The current version (these files) is 0.07b. It and previous versions can be found in the Downloads folder, zipped for your convenience.
Instructions.txt has a good amount of documentation.
EMC 2 Arduino is known to work with ATMega2560 based Arduinos. 32u4 based Arduinos (Leonardo, etc.) can also work, but some communication issues are still being ironed out.
