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:
CNC:
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
Here you can view a video of my first test cut:

hi Kyle,
I went to WWW.BUILDYOURCNC.COM,, to get the plans for the 24" x 48" CNC
Router. They are no longer available from that site. Instead they are offering a kit for m$2567.00. I was looking to build one from plans for way less then that. Any chance of directing me to such plans?
I enjoyed your Instruct able, and it was the answer I needed to get int CNC. Can you help me??
Regards,
Ken

How easy is it to programme the router to the pc or cutting software? Cheers

Could you provide the sketchup file if you still have it?

Could you add a schematic about wiring break board and step driver?

Could you use this to cut the pieces needed for a wikihouse? Would you need a biger rig?

What is weight of x-axis assembly of CNC in this instructable?

Perhaps a dumb question here, but you could theoretically expand the design as large as you wanted right? like say if I wanted to make a 48" x 48" instead?

Good. I like it

I see the nice way you've got the bearings on the top runners, how about the tension? Have you made it adjustable? As in, maybe sprung loaded bearings on the bottom?
A nice instructable, I'm looking at putting something this size together, I'm using a Zen 7x7 at the mo. I don't need super critical tolerances, it's machining wood, +- 1mm is plenty good enough for me.
Thanks for sharing!

Great. Wonder what are the cart dimensions? How high mainly. Just curious.

That is some good work, man! If you get a chance, let me know what you think of my design.

I wonder if you can cut out an oathkeeper keyblade from Kingdom hearts. I built the oblivion key using a jigsaw and dremel but it looks kinda amateur-ish. 42" by ~16"

What steps do you take to keep dust/sawdust, etc. from getting into the PC? I would be concerned about the PC being so close to the CNC table.
