Mendel X Y axis accuracy doubling mod.

I'm rewriting this text for the second time because I accidentally deleted everything, which is incredibly frustrating. This modification significantly improves the accuracy on the X and Y axes of a Reprap Mendel by creating a double pulley system. The result is that there's much less play or lash in my x-axis now, making every movement feel sharper. Another advantage is that this mod allows your machine to maintain its original speed. You can see the first test here: http://youtu.be/vVHvbCfxZdU The only change I made was to replace the Y-belt brackets with ones that have captured nuts and countersunk bolts.
