In various embodiments, a surgical instrument system comprising an end effector, an elongate shaft, a motor-powered closure member, and a motor-powered firing system is disclosed. The end effector comprises an anvil and a cartridge channel. The cartridge channel is configured to receive a staple cartridge. The motor-powered closure member is moveable between a first position and a second position during a closure stroke. The motor-powered closure member couples the anvil and the channel during the closure stroke. The motor-powered firing system comprises a first flange configured to engage the anvil during a firing stroke, a second flange configured to engage the cartridge channel during the firing stroke, and a rotatable drive screw operable to transmit the firing stroke. The first and second flanges couple the anvil and the channel during the firing stroke. The motor-powered closure member and the motor-powered firing system are separately actuatable.
