1. A surgical instrument system, comprising:

  • an end effector, comprising;

    an anvil;

    a staple cartridge, comprising;

    a proximal end;

    a distal end;

    a plurality of staple cavities; and

    a plurality of staples removably stored in the staple cavities; and

    a sled slidable within the staple cartridge to move the staples toward the anvil;

    a firing member movable relative to the staple cartridge to move the sled from the proximal end toward the distal end of the staple cartridge during a firing stroke;

    a shaft defining a longitudinal axis;

    an articulation joint, wherein the end effector is rotatably connected to the shaft about the articulation joint between an unarticulated position and an articulated position; and

    adjusting means for adjusting the length of the firing stroke as a function of the degree in which the end effector is articulated relative to the longitudinal axis.
