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 this video, 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!
