Prototype #3: final prototype
This is insides of the Y axis prototype, Z axis is similar as well. The build is rough as it is only used as a proof of concept. The final material will be out of aluminum. As you can see the mechanics is simple: motor turns screw, screw turns nut, nut moves tray.
Here are pictures of the final proof-of-concept prototype model of Concept 3. This is where I ended my first semester of my school project. It is a fully functional 3 axis CNC machine. It's setup at about 120 inch per minute, and an accuracy of about 0.015" I used a floor engraver setup configuration as supposed to a typical desktop CNC configuration. In this setup I am capable of doing CNC work on the surface below which I demonstrated during my end of semester presentation. Built time: 1.5 weeks
