Abstract
A 3D printer is configured to print a 3D part. The 3D printer includes a print head carried by a head gantry and configured to operably move the print head along planar tool paths. The 3D printer includes at least one head gantry actuator coupled to the head gantry and configured to move the print head in a plane and a print head actuator coupled to the print head and configured to move the print head in a direction substantially orthogonal to the plane. A sensor is fixedly mounted to the print head and configured to output a first signal that is directly or indirectly related to an acceleration of the print head, and a gyroscope is fixedly mounted to the print head and configured to output a second signal related to a rotational position of the print head. The 3D printer includes a controller configured to determine a rotational position error of the print head relative to a predetermined position based on the first signal and the second signal and to output one or more signals to the at least one head gantry actuator and/or the print head actuator to compensate for the rotational position error of the print head.
