Introduction: Homemade 2'x4' Wood CNC Router
Here I am going to show how I made my CNC (Computer Numerical Controlled) router. The table measures 24"x48" and the cutting envelope is about 19”x38.” I made this CNC when I was 17 and if you would like to see more on this CNC, visit my website at www.KylesWoodworking.com
NOTICE: THE PLANS AND DESIGN FOR THIS CNC WHERE PRODUCED AND PURCHASED FROM WWW.BUILDYOURCNC.COM, ALL CREDIT FOR THE PLANS GO TO BUILD YOUR CNC. THE CNC STAND, COMPUTER STAND, AND ELECTRONICS BOX WHERE DESIGNED BY ME.
Step 1: CNC and Stand Assembly
Here you can see time lapse videos of me assembling the CNC and stand:
Step 2: Lead Screws
The lead screws are what make the x,y, and z axis move by turning them with a motor. I went to the hardware store and picked up 1/2" threaded rods to use as the lead screws.
Step 3: CNC Electronics
(3) 425 oz-in stepping motors
(3) Drivers (3.0Amp 24-40 Volts, 1-1/64 micro-stepping)
(1) 36v 8.8a Power Supply
(1) Breakout board
I wired all the electronics up and added a few more features such as, an e-stop switch, limit switches, and power switches for the router, shop vac, electronics, and the stepping motors.
Here you can view a video of the electronics:
Step 4: Finished and Test Cut
