1. An additive manufacturing system, comprising:
an energy beam system comprising one or more energy beam sources; and
a position measurement system comprising a position measurement assembly attached to the energy beam system, the position measurement assembly comprising one or more position sensors and one or more mounting brackets attaching the one or more position sensors to the energy beam system;
wherein the energy beam system is situated in a fixed position relative to a reference plane, the reference plane coinciding with an expected position of a build plane based on a calibration; and
wherein the position measurement system is configured to determine a position of the build plane relative to the reference plane and to adjust the reference plane based at least in part on the determined position of the build plane.
