Abstract
A method for identifying an angle of roll for a multi-nozzle extruder includes moving the extruder in a first process direction to form a first set of swaths of extrusion material using two nozzles in the extruder and moving the extruder in a second process direction to form a second set of swaths of extrusion material. The method further includes identifying a location of one nozzle relative to the other nozzle in two dimensions based on cross-process direction distances between the first and second sets of swaths and identifying the angle of extruder roll for the extruder based on the location of the one nozzle and a predetermined geometry of the extruder.
