belt on belt/servobelt

[tropostudio]

I'm pretty impressed with Mike Everman's Servo Belt concept. I first ran across it in the threads on CNC zone Gerry refers to. There more on it on Everman's own blog at http://mikeeverman.com/. It seems like a great solution to the problems of belt stretch in conventional systems and the limited tooth engagement and resulting low shear strength and backlash compensation I see in CNC fabric cutters like this: http://carlsondesign.com/plotter-cut...plotter-cutter.

What about making the belt on the drive motor side a continuous loop (tank tread) and skipping the full length top belt? If you mount the belt system upside down, similar to how you see racks mounted on many CNC router axes, the protection from dust or chips seems unmerited.
