Claim 13:
14. A non-transitory machine-readable storage medium comprising instructions that upon execution cause a controller to:
receive measurement data from a sensor responsive to vibrations of a spreader across a range of frequencies, the spreader for use in dispensing a build material onto a target surface;
identify, based on the measurement data from the sensor, a resonant frequency associated with the spreader at which the spreader is not to be vibrated;
identify, based on the measurement data from the sensor, a further frequency at which an amplitude of a vibration of the spreader is below a threshold; and
control, based on identifying the resonant frequency associated with the spreader and based on identifying the further frequency at which the amplitude of the vibration of the spreader is below the threshold, a frequency of the vibration of the spreader.
