1. A tool comprising:
a housing having a nosepiece assembly;
a motor;
a drive actuator;
a magazine assembly configured to hold a plurality of fasteners;
a feed assembly associated with the magazine assembly configured to advance each of the plurality of fasteners in a feed direction to present a lead fastener into the nosepiece assembly, the feed assembly comprising a feed actuator configured to move said lead fastener into the nosepiece assembly;
a driver provided in the housing and configured for translational movement within a drive channel along a drive axis to drive the lead fastener into a workpiece;
a drive system, associated with the drive actuator, configured to selectively drive the driver along the drive axis; and
a controller connected to the feed actuator and the drive actuator to implement a firing sequence for driving each lead fastener into the workpiece using the driver and feeding the lead fastener into the nosepiece assembly, wherein the firing sequence comprises a first electric pulse to the drive actuator and a second electric pulse to the feed actuator, and wherein the motor is activated for at least a portion of a time after the first electric pulse and before the second electric pulse, but the motor is not activated for at least a portion of a time during the first electric pulse and at least a portion of a time during the second electric pulse.
