Install Dependencies​

tip

It is recommended to use SSH tools such as MobaXterm_Personal for operation.

tip

The FLY host machine does not need to execute, as it already comes with the accelerometer dependency package.

  • Please execute the following commands in sequence to install the dependencies.

  • Note that depending on the performance of your CPU, it may take a lot of time, up to 10-20 minutes. Please be patient and wait for the installation to complete. In some cases, if the motherboard's RAM is too low, the installation may fail.

    sudo apt install python3-numpy python3-matplotlib libatlas-base-dev
    ~/klippy-env/bin/pip install matplotlib numpy

Test Accelerometer​

  • You need to reset before executing.
  • Execute ACCELEROMETER_QUERY in the console.
  • For multiple accelerometers, you can specify testing one by using ACCELEROMETER_QUERY CHIP=<ADXL>, where <ADXL> needs to be replaced with the corresponding accelerometer name.
  • If there is an error, please check the wiring and configuration.
  • The normal output is shown below:
  • This allows you to perform resonance compensation measurement.

Calibrate Accelerometer​

  • Reset.
  • Enter SHAPER_CALIBRATE in the console to start automatic calibration for X and Y.
  • After calibration is completed, execute SAVE_CONFIG to save the data.
  • You can also use SHAPER_CALIBRATE AXIS=X to automatically calibrate one axis.
  • The calibration process may take a long time, so please be patient.
tip

Attention! If the printer vibrates too violently during the test, please press the emergency stop immediately or send M112 to stop it.

  • An excessively high accel_per_hz can make vibrations more intense; you can reduce it appropriately.
