The Shapeoko CNC Mill looks like this:
Here is the mill in action (the rails are longer than the model the club has purchased):
To use the mill, the following software is required:
1. Google Sketchup to create 2D part files. Sketchup is a free program for drawing computer models of 3D objects.
2. Use the phlatscripts plugin to generate gcode. Gcode is a machine language that tells the drill bit of the CNC mill where to go in a coordinate system and how fast to cut.
3. Use grbl to interpret the gcode for the Arduino and then send it to the Arduino. Grbl is a free, open source, high performance CNC milling controller written in optimized C that will run on a straight Arduino. Grbl will be installed directly onto the Arduino once. The program we will use to send the gcode is gcodesender.
Challenge: Build a small emblem to be printed in cardboard.
