A stapling system comprising a housing is disclosed. The housing comprises a first rotatable drive disk. The stapling system further comprises a closure member configured to transmit a closing motion from the first rotatable drive disk to an anvil to move the anvil into a closed position. The stapling system further comprises a second rotatable drive disk, wherein the second rotatable drive disk is operable independently of the first rotatable drive disk and is configured to transmit a second operative motion. The stapling system further comprises a firing member configured to perform a firing stroke in response to the second operative motion. The stapling system further comprises a control system that assures that the closing motion and the firing stroke are separate and distinct and that prevents the firing stroke from occurring prior to the completion of the closing motion.
