Aluminum pullies. There seemed to be a fine line between just tight enough to print and so tight that the plastic around the idler pulley warps during printing. If there were a way to set the max speed of movement we'd be fine -- the belts only slip when there's an immediate high-speed reversal of the 'Y' motor (coincidentally, also the hardest motor to tension).
