Building Your Own CNC Router

Now the first things we need to consider when building a router is the length of each axis like say we want a X axis of 800 mm, a Y axis of 300mm and a Z axis of 150 mm

here is a pic of my X axis showing how the nut is held and also the linear bearings where the shafts need a good clean with some 1200 emery cloth

For the Y and Z axis heres a pic to show

As you can see the Y axis is a metal block with oil light bearings and by making this with no slop the Y axis ball screw works just fine.

Also one can see the Z axis where 2 each linear bearings are used and the ball screw is a 2 start thread so rapid up and down motions can jad for drilling at high speed and also for quick withdrawal. Also one will notice the runner for the stops on each axis.

I can go into more detail later but here is the grasp.
