Giant 20' x 3' x 2' router build

Call me sad but really getting excited now! Just mocked the z axis up with some wood plates to try and figure a few things out and all looks like it should be relatively simple.

I have decided to go with all your suggestions and do the double ball screw and all so add the 3rd vertical rail to the Z axis. Its going to cost a lot more but it will actually probably be more simple and figured probably give me less headaches in the long run and wont kick myself wishing i had done it that way.

The X axis will have to stay rack and pinion as i cant see any other real way to do it other than belt which people have said is not such a good idea on that length.

I will order parts tomorrow then will need to get a few more plates made up to bolt it all up.

still no real idea on what motors im going to use but hopefully some one will be able to help me with that.
