CNC Gantry Machine

This is a 3-axis CNC gantry machine which has roughly 14" x 14" horizontal and 4" vertical movement.  It's an improvement from a previous design I had built.  This frame was designed using 1/2" thick polycarbonate since I had received several pieces of this material for free and thought this a good use.  I HAVE NOT YET BUILT THIS MACHINE, but as I do I'll make updates as needed.

Click for zip files containing the ProEngineer (Wildfire 3.0), STEP, and IGES files of the model.  At some point I'll add pdf files of the drawings.
