Homemade CNC Router

For a class project, I made a homemade CNC router with a 30” x 30” cutting area. The machine is all controlled using an Arduino and uses NEMA 23 Stepper motors. I have done many projects using this machine since I built it. The linear rails on the machine are each using a different technique. The X-axis uses Rollerblade wheels to slide, the Y-axis uses skateboard baring and the Z-Axis uses drawer slides.
