Claim 9:
10. A method of calibrating a three-dimensional printer, the method comprising:
lowering, via an actuator, a plurality of nozzle holder assemblies, each of the plurality of nozzle holder assemblies comprising:
a mount operable to be secured to the three-dimensional printer;
a printer nozzle shaft movably coupled to the mount along a predetermined length;
a locking mechanism configured to fix the printer nozzle shaft relative to the mount at any position along the predetermined length;
a sensor configured to detect when the printer nozzle shaft moves relative to the mount;
a bushing coupled to the mount; and
a bearing positioned in the bushing and supporting the printer nozzle shaft;
sensing, via the sensor of each of the plurality of nozzle holder assemblies, when printer nozzle shafts move relative to mounts of the plurality of nozzle holder assemblies;
emitting, via the sensor of each of the plurality of nozzle holder assemblies, signals indicative of movement of the printer nozzle shafts; and fixing, via the locking mechanism of each of the plurality of nozzle holder assemblies, positions of the printer nozzle shafts relative to their respective mounts.
