Accelerometer Usage
Usage Tutorial
Install Dependencies
warning
- No need to execute for FLY host computer, as it already comes with the accelerometer dependency package
- Must execute for non-FLY host computers! It is recommended to operate using SSH tools such as
MobaXterm_Personal
-
Please execute the commands below in order to install dependencies
-
Note that depending on the CPU performance, this may take a long time, up to 10-20 minutes. Please wait patiently for the installation to complete. In some cases, installation may fail if the motherboard has too little RAM.
sudo apt install python3-numpy python3-matplotlib libatlas-base-dev
~/klippy-env/bin/pip install matplotlib numpy
Test Accelerometer
- Homing must be performed before execution
- Execute
ACCELEROMETER_QUERY
in the console - For multiple accelerometers, you can specify which one to test using
ACCELEROMETER_QUERY CHIP=<ADXL>
, where<ADXL>
should be replaced with the corresponding accelerometer name - If an error occurs, please check wiring and configuration
- A normal output will look like the image below
- With this, you can proceed with measuring and compensating for resonance
Calibrate Accelerometer
- Home the printer
- Enter the command below in the console to begin automatic calibration of X and Y axes
SHAPER_CALIBRATE
- After calibration completes, run the command below to save the data
SAVE_CONFIG
- The calibration process might take a while, please be patient
- If you wish to calibrate only one axis, you may use the command below
SHAPER_CALIBRATE AXIS=X
tip
Note! If the printer vibrates excessively during testing, please press the emergency stop or send M112
to stop immediately
-
Excessively high
accel_per_hz
can cause strong vibrations, you may appropriately reduce it[resonance_tester]
accel_per_hz: 50 # Default value is 75
