Guide
- Aquire an ADXL345
- Solder 6 wires on to the ADXL345.
- Monut the ADXL to you Extruder. If you got a moving printbed as X you need to move the ADXL345 halfway into the calibration guide. Watch NEROs video!
- Connect the 6 wires to your Raspberry Pi - DO it correct please or you COULD risk frying either your ADXL345, Your Raspberry Pi... or both ;-)
- Install the software - if you havent done so already.
- Update your Raspberry Pi:
sudo apt update -ysudo apt upgrade -y- Install "numpy" - Note: this will take quite some time - NERO says 20 minutes. It was faster on my Raspberry Pi 4 but still...
~/klippy-env/bin/pip install -v numpy- Install additional dependencies
sudo apt install python-numpy python-matplotlib- Configure your Raspberry Pi as a secondary MCU - Note: I got this working together with screen on my Creality Ender 5 Plus :-)
sudo cp ~/klipper/scripts/klipper-mcu-start.sh /etc/init.d/klipper_mcusudo update-rc.d klipper_mcu defaults- Rebuild the microcontroller code
cd ~/klipper/make menuconfig
Credits
I wrote this guide using NERO 3Ds Youtube video as inspiration, so I hade the commands needed handy to cut'n paste into my Raspberry Pi when ever I want to rerun the calibration.
