Attached are my designs for the CNC Router we did in Episode 2. There are certainly things I would do differently now, but it did function. I used PVC plastic, but MDF is a popular material for this as well.
You may need to modify it depending on the physical size of the stepper motors. I don't like when I see homemade CNC machines with motors hanging off the ends, so I made mine in-line. The side effect is the design and spacing is more aggressively tight, so a larger motor might not fit.
The cutting motor is a Porter Cable Laminate router. You can get one at Farm & Fleet for around $100.
I'll post the designs for the Xbox 360 laptop probably in Episode 6. Also, will offer the plans for Portable Work Bench whenever it shows up, probably episode 4.
