Abstract

A fluid dispense system having a computer control system that operatively controls a stepper motor driving a nutating pump. The stepper motor actuates the nutating pump piston through partial revolutions. The computer control system determines the number of stepper motor steps required to pump a desired amount of fluid by the nutating pump by rotating the piston through segments which are less than a full revolution.
