Abstract: A method for controlling a motor of a power tool including performing a load test on a battery pack of the power tool, determining, via a first controller, a first mechanism control scheme based on the load test, receiving, via the first controller, a user input indicative of beginning an operation cycle of the power tool, and isolating the first controller from a second controller. The method further including controlling, via the first controller, the motor based on the first mechanism control scheme, sensing a dataset indicative of a result of the operation cycle based on the first mechanism control scheme, receiving, via the second controller, the dataset, connecting the first controller to the second controller upon completion of the operation cycle, transmitting, via the second controller, the dataset to the first controller, and determining, via the first controller, a second mechanism control scheme based on the dataset.

Abstract: A powered fastener driver includes a first cylinder, a first piston positioned within the first cylinder, a second cylinder in fluid communication with the first cylinder, and a second piston positioned within the second cylinder. The first piston is moveable between a top-dead-center position and at or near a bottom-dead-center position and the second piston is moveable between a top-dead-center position and a bottom-dead-center position to initiate a fastener driving cycle. A drive blade is coupled to the second piston for movement therewith and a drive mechanism is configured to drive the first piston between the top-dead-center position and at or near the bottom-dead-center position. The drive mechanism includes a crank arm that rotates less than 360 degrees for moving the first piston from at or near the bottom-dead-center position and the top-dead-center position and then back to at or near the bottom-dead-center position to complete the fastener driving cycle.

The drive mechanism includes a crank arm configured to rotate less than 360 degrees in a first direction to complete a first fastener driving cycle and less than 360 degrees in an opposite, second direction to complete a subsequent second fastener driving cycle.
