DIY Arduino CNC: Z Axis Upgrade & ChiliPeppr! Widget34

In this video, we added a Z-axis spring and bushing that lets us use the project as a pen plotter with a pen "lift" and a pressure spring that will accommodate any variations in paper thickness, unevenness, etc! We also look at the awesome ChiliPeppr interface which is a incredible - a huge step above the Universal G-Code Sender we used in Parts 1 and 2!

In Part 1, we set up the Arduino & GRBL shield. Now, let's use inexpensive linear motion hardware (links below!) to assemble the bearings, rods and steppers into a functional CNC machine!

In Part 2, we look at the CAD model of the machine, discuss basic design philosophy, test it's accuracy (amazing results!), then do the final GRBL set up so that we can export CAM G-Code to use on the machine!
