+## Printer firmware build and update
+1. Access klipper host using ssh
+```
+ssh ender3k
+```
+
+2. Stop Klipper service
+```
+sudo service klipper stop
+```
+
+3. Browse to Klipper directory:
+```
+cd ~/klipper
+```
+
+4. Pull the last version of the Klipper firmware from Github:
+```
+git pull
+```
+
+5. Clean up working directory before building firmware
+```
+make clean
+```
+
+6. Check the firmware build configuration 
+```
+make menuconfig
+```
+![Klipper firmaware build configuration](klipper/img/klipper-skr-mini-e3-v2-fw-config.png)
+
+7. Build the firmaware:
+```
+make
+```
+
+8. Transfer the built firmware on an micro SD card
+The built firmware `klipper.bin` is in the `~/klipper/out/` directory
+Use a SCP client to retreive it, and rename it **`firmware.bin`**.
+
+9. Flash the new firmware to the printer's SKR mini E3 v2 board
+    1. Turn off the printer power.
+    2. Introduce the SD card into the SKR board reader
+    3. Turn back on the printer power.
+
+11. Restart Klipper service
+```
+sudo service klipper start
+```
+
+12. Check Klipper service is properly restarted
+```
+sudo service klipper status
+```

+
+### Software prereqiusites
+Note that resonance measurements and shaper auto-calibration require additional software dependencies not installed by default. First, run on your Raspberry Pi the following commands:
+```
+sudo apt update
+sudo apt install python3-numpy python3-matplotlib libatlas-base-dev libopenblas-base
+```
+
+Details on Klipper [documentation](https://www.klipper3d.org/Measuring_Resonances.html#software-installation)
+
+### Firmware configuration and build
+1. Configure the firmaware:
+```
+cd ~/klipper
+make clean
+make menuconfig
+```
+![ADXL345 Firmare config](klipper/img/klipper-adxl345-fw-config.png)
+
+2. Build the firmware:
+```
+make
+```
+
+### Firmware flash
+1. Set the ADXL345 board in DFU mode by plugin it to the USB cable while maintaining the RST switch down.
+
+2. Check that the board is actually in DFU mode
+```
+lsusb
+```
+![ADXL345 board in DFU mode](klipper/img/ender3-adxl345-dfu-mode.png)
+
+4. Note the device `ID` (in our example: `2e8a:0003`)
+
+5. Flash the firmware
+```
+make flash FLASH_DEVICE=2e8a:0003
+```
+
+Once flashed, the board will automatically reboot and goes back in operation mode.

+Then  create the `98-klipper.rules` file in the `/etc/udev/rules.d/` folder:
+```
+sudo touch /etc/udev/rules.d/98-klipper.rules

+
+Retreive `idVendor` and `idProduct` for the Klipper MCU:
+1. Retrieve Klipper MCU ID
+```
+lsusb
+```
+![Find Klipper MCU ID](klipper/img/ender3-find-mcu-id.png)
+
+2. Retrieve `idVendor` and `idProduct` using the Klipper MCU ID
+```
+lsusb -v -d 1d50:614e | grep id
+```
+![idVendor and idProduct](klipper/img/ender3-klipper-mcu-idvendor-idproduct.png)

+Then add the following text into the `98-klipper.rules` file just created:
+
+1. Edit the `98-klipper.rules` file
+```
+sudo nano /etc/udev/rules.d/98-klipper.rules
