1. An additive manufacturing system comprising:
an energy source configured to direct an energy beam toward a component to form a melt pool; and
a material delivery device comprising:
a feed actuator configured to feed a wire toward the melt pool; and
control circuitry comprising a measurement circuit configured to, in response to a control signal indicating measurement of an arc voltage:
discharge a current to the wire to generate an arc from the wire to the component; and
measure the arc voltage between the wire and the component corresponding to a distance between the wire and the melt pool.
