If the bed is light weight enough, higher feed rates wont be a problem? This is supposed to be the advantage of the raising bed style, yeah?

For the price and materials, it seems pretty tempting... though I don't have any idea about its electronics and controls. I'm guessing at that price, it has the cheapest + nastiest arduino knock offs.
