<p><strong>Warning!</strong> It is not advisable to run the shaper auto-calibration very
frequently (e.g. before every print, or every day). In order to determine
resonance frequencies, autocalibration creates intensive vibrations on each of
resonance frequencies, auto-calibration creates intensive vibrations on each of
the axes. Generally, 3D printers are not designed to withstand a prolonged
exposure to vibrations near the resonance frequencies. Doing so may increase
wear of the printer components and reduce their lifespan. There is also an
