yep they tension the belt use 1mm on the  front  screws and 0.5mm on the rear screws. I also have both one ways but not a Zero S? If you are only going FWD then you can put the front pulley in any position so yes it should work fine

wouldn't you get more tension on the belt if you only raised the rear? because raising both up, in the end the center belt is only getting that extra .5mm? I got the one way as well for it
