Shift to the small ring. And lowest gear in back. (biggest cog) Use the limit screw to adjust the derailure to make contact with the chain. (I know it's counterintuitive) loosen the fixing bolt.. pull the slack out of the cable. Tighten the fixing bolt. Now loosen the limit screw to take the slack out of the cable and move the derailuer off the chain. Now you have a zero position with no slack.
