Abstract
A method for identifying an angular deviation in the orientation of a multi-nozzle extruder includes moving the multi-nozzle extruder in a first process direction to form a first extrusion material swath and moving the multi-nozzle extruder in a second process direction opposing the first process direction to form a second extrusion material swath. The method further includes identifying widths and heights of the swaths from scanned image data and identifying a component of angular deviation for the multi-nozzle extruder with reference to at least one of a difference between the first swath width and the second swath width and another difference between the first swath height and the second swath height.
