Hi all.

I am now working on a set of plans for a homemade CnC router.
I want it to have a cutting area of 24" x 36". I am gonna use 175oz/in stepper motors.

I am planning on using rails down the sides of the table for the Gantry to ride on the x - axis. The Gantry will have v-groove bearings to ride on the rail 2 on top of the rail and one below the rail.

Anyone made a table this size?

I would appreciate any ideas anyone can give me.

I will post the plans as i can.

My table is that size. Best of luck with the project!

Tell me about your table. The bearings and things you use.

Have a look here. It's all there.

HERE IS THE TABLE AND GANTRY.

What material will you use? MDF?

Why is the table so tall?

Looks nice so far!

MATERIAL: Probably a combination of MDF and Plywood.


Table Height: Thats just the way it came out. Its gonna have the drive screw going underneath the table in the middle.

The gantry is gonna ride on rails on the outside of the table. With a V-groove bearing on top and bottom of the rail. That's why it came out so high.

What 3D program can i use to gram artworks? Any free ones?

Hey Little Joe,

Just one comment..... if you put the linear rail on the upper side of your baseframe instead of the lower side it will reduce the sway in the gantry.

Also, have a look at ChuckKnight's thread on his wood/mdf router. It has some good pictures and stuff.

At mine, it's in the same aisle as the plywood, at the edge of the lumber department. Easy to find.

here is the latest revision to my plans.

notice i moved the rails up. and also notice that i added the rail alignment blocks.

Ljoe - I'll keep watching and waiting to hear/see how you handle the spindle/router between the rails on the y axis.

Access to the collet and all were my concerns when I was considering a similar approach.

It does look sturdy though!

Joe,
In some of my brain storming on paper I thought about a pivot up router. Using a hinge to pivot it up between the rails and a couple of wingnuts to lock it in the down position.
Like I said it's brain storming, not necessarly good.

Joe,
Good out of the box design.
Currently the angle iron is mounted to ears on each side, It might be stronger to eleminate the ears and make the end pieces the same width all over. MDF doesn't have any grain like wood so it can brake.
