I really like the Clone4D or 3D style. Seems pretty simple. Maybe I'm wrong. I've looked for plans but only found relating to I believe is called the 'carver copier, or the like. My plan is to roughly reverse engineer the Clone style, from looking at photos, and some internet research. Limited in tooling, I've been figuring ways to mill/cut AL with a wood router and end mill. The big Aluminum side plates mounted to linear bearings for the x,y really turn me on. Sorry can't be of real help. But I feel you, on a similar plane. Good luck.
