I thought I'd give a little more detail about why I chose a hexapod over other designs.

First of all, I get full 6-axis movement, as I mentioned earlier in this thread.

Second, I liked the notion that I could build this machine without having to make a lot of precision parts. I didn't have to start with an existing milling machine. No parts are precision cut or positioned other than the special plate I made with calibration points marked on it. The RoboFac software compensates for accuracy problems.

Third, I've made the machine with a minimal amount of specialized materials. Nearly all the mechanical parts come from Home Depot, Lowe's, MSC, or Metal Supermarkets (my local metal supplier).
