1. A method for calibrating a print head for use in an additive manufacturing system, the method comprising:
- positioning the print head at over a calibration target retained by a moveable platen of the additive manufacturing system, wherein the calibration target has a top surface with a plurality of edges;
moving a tip of the print head along the top surface in a first direction until the tip drops off of a first edge of the plurality of edges;
identifying a first coordinate location at the first edge where the tip dropped;
moving the tip along the top surface in a second direction that is substantially perpendicular to the first direction until the tip drops off of a second edge of the plurality of edges;
identifying a second coordinate location at the second edge where the tip dropped;
determining a coordinate point of the calibration target based at least in part on the first coordinate location and the second coordinate location; and
setting a calibration parameter for the print head in a horizontal plane based on the determined coordinate point.
