Started my build this week on a 4'x8' router made of 8020 and some quality linear drive components. Here are some of the parts I am using

25mm Hiwin Linear rails on all axis
.75" x .5" lead, Roton Ball screws x and y
.625 x .2"lead on z
welded steel 2" square tubing frame
8020 table frame and gantry assembly

thinking im going to use keling servo motors on all axis most likely the largest servos they have for the x and y and drop down a few sizes for the z.

Pictures are of the overall design. Keeping in mind the z axis isnt worked out yet still in the design stage. I initially was going to mount the y rails on the gantry, on the plane perpendicular to the table. But decided that by mounting them on the top and bottom of cross members the z axis assembly will move back a few inches giving me less moment on the x axis bearings. Also im thinking becuase of this the cross members can be shortened so that they do not extend pass the gantry uprights cleaning up the design a bit.

I will post pictures of the build so far tomorrow.
