Nophead clearly has a ton of experience and has ended up in a similar design space as Ord Bot, albeit with MDF basically providing the rigidity that rods and bearings lack. Good to see. Saying that, I just don't see why the RepRap folks insist on staying with rods. Is it basically because they're commoditised and some day they hope to be able to replace them with something printable? If so, then with a tall enough machine and some kind of support structure, why not try to print Makerslide? Difficult, but a heck of a lot easier than rods.
