Abstract
A method for calibrating a fluid dispensing system includes the steps of locating an external reference point with an optical sensor, moving a fluid dispenser to the external reference point, dispensing fluid with the fluid dispenser at the external reference point, locating the dispensed fluid with the optical sensor, calculating a distance between the location of the external reference point and the location of the dispensed fluid, determining a correction value based at least in part on the calculated distance, and using the correction value to improve placement accuracy of dispensed fluid.
Claims8
