This is an old revision of the document!
In 2013, Sam purchased a Shapeoko kit. Made good progress at first, and then it languished in his garage for a few years.
In December 2015, he took it to the space in hopes it would get finished there. It's making progress already 
Electronics: Arduino Uno with gShield. Computer is a BeagleBone Black.
Current status: Preliminarily Functional.
Software: We are now using bCNC as the Gcode sender. It also has some CAM functionality.
To-Do List
Base: Drill holes in base to mount to whatever bench it will sit on
Calibration: seems ok at the moment. Maybe double check with a dial indicator?
Limit Switches: Use mechanical switches for X-/X+/Y-/Y+/Z+. Maybe build/buy a touch plate setup for Z-? Printed the base of a touch plate, and Steve will cut out a brass disc for it on his CNC router. (X- & Y- switches are installed on 3D printed mounts. Additional T-nuts are needed to install X+ & Y+ switches.)
