14. A method for controlling a surgical instrument assembly that includes an end effector with a first jaw and a second jaw that are moveable between an open position and a closed position, the method comprising:
operating a firing motor to rotate a firing drive shaft, thereby axially moving a firing actuator, the firing actuator being engaged with the firing drive shaft and the first and second jaws of the end effector;
measuring a load on the firing actuator; and
adjusting the load on the firing actuator by operating a closure motor to rotate a closure drive shaft, thereby axially moving a closure actuator engaged with the closure drive shaft and varying a distance between the closure actuator and the firing actuator, the closing actuator further being engaged with the first jaw and second jaw such that distal advancement of the closure actuator along the closure drive shaft moves the end effector from the open position to the closed position.
