 <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, 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 increased risk of some parts unscrewing or becoming loose. Always check that all parts of the printer (including the ones that may normally not move) are securely fixed in place after each auto-tuning.</p>
 <p>此外，由于测量中的一些噪音，每次校准得到的调谐结果会略有不同。不过，这些噪音一般不会对打印质量产生太大影响。然而，我们仍然建议仔细检查建议的参数，并在使用前打印一些测试件以确认它们是正确的。</p>

-<p>It is possible to generate the raw accelerometer data and process it offline (e.g. on a host machine), for example to find resonances. In order to do so, run the following commands via Octoprint terminal:</p>
