Install Dependency Packages
warning
- The FLY host machine does not need to execute this, as it already comes with the accelerometer dependency package.
- Non-FLY host machines must execute this! It is recommended to use SSH tools such as
MobaXterm_Personal
for operation.
-
Please execute the following commands sequentially to install the dependency packages.
-
Please note that, depending on the CPU performance, it may take a lot of time, up to 10-20 minutes. Please wait patiently until installation is 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 home first before executing.
- Execute
ACCELEROMETER_QUERY
in the console. - For multiple accelerometers, specify testing one by using
ACCELEROMETER_QUERY CHIP=<ADXL>
, where<ADXL>
needs to be modified to the corresponding accelerometer name. - If there is an error, please check the wiring and configuration.
- Normal output is shown below:
- This can then be used for resonance compensation measurement.
Calibrate Accelerometer
- Home first.
- Input
SHAPER_CALIBRATE
in the console, which will 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.
-
A high
accel_per_hz
can make the vibration intense; you can appropriately reduce it.[resonance_tester]
accel_per_hz: 50 # Default value is 75
