Hardware You’ll Need

• Raspberry Pi or Orange Pi
• Micro USB Cable

Software You’ll Need

• PuTTY (SSH client)
• FileZilla (for file transfers)

Disclaimer:

CAUTION: If you still have the stock firwmare you are unable to flash Klipper via USB. You need to flash a bootloader first. Discover How To Install Bootloader on Ender 3 2018 using Orange Pi Zero LTS

If you mount Marlin then you are good to go.

3. Access the Raspberry Pi / Orange Pi via SSH

1. Find the Raspberry Pi’s IP Address:
   • You can find it via your router’s admin panel or use a network scanner like Angry IP Scanner.
2. Connect to the Raspberry Pi via SSH:
   • Open a terminal or an SSH client (like PuTTY) and connect using the IP address.
   • If you cannot connect, refer to a guide like How to Connect via SSH Using PuTTY.
3. Update the Raspberry Pi:
   • Run the following commands:

sudo apt update && sudo apt upgrade -y

4. Install KIAUH

1. Clone the KIAUH Repository (non-root user):

cd ~/
git clone https://github.com/th33xitus/kiauh.git ~/kiauh

1. Navigate to the KIAUH Directory:

cd ~/kiauh

1. Start KIAUH:

./kiauh.sh

5. Install Klipper, Moonraker, and a Web Interface

In the KIAUH menu:

1. Install Klipper to install the Klipper firmware.
2. Install Moonraker to set up the Klipper API server.
3. Install a Web Interface: Choose either Mainsail or Fluidd for a user-friendly web interface.

After installation, reboot the device:

sudo reboot

6. Compile Klipper Firmware

1. After rebooting, reconnect to the device via SSH.
2. Open the KIAUH menu:

cd ~/klipper/
make menuconfig

1. Select the following configurations:
   • Microcontroller Architecture: Atmel AVR
   • Processor Model: ATmega1284p
   • Communication Interface: Serial (on USART0)
2. Press Q to exit and Save
3. Compile the firmware:

make

The compiled firmware will be saved as klipper.elf.hex in the /out directory.

7. Flash Klipper Firmware

Determine the serial port to the printer board. Run:

ls /dev/serial/by-id/*

It should show something like:

/dev/serial/by-id/usb-1a86_USB2.0-Serial-if00-port0

Flash the firmware in your board:

sudo service klipper stop
make flash FLASH_DEVICE=/dev/serial/by-id/usb-1a86_USB2.0-Serial-if00-port0
sudo service klipper start

Awesome! Now your Ender 3 runs klipper!

8. Configure Klipper

1. Create the printer.cfg file:
   • Access the web interface (Mainsail or Fluidd) by entering the Raspberry Pi’s IP address in a browser.
   • Upload or create a printer.cfg file. Use the Ender 3 template from Klipper:
     Ender 3 Config File
   • If you have installed BlTouch, follow this guide: How to Configure BLTouch in Ender 3 2018 using Klipper and Mainsail
2. Save and Restart:
   • Save the file and restart the Klipper service.
3. Test the Connection:
   • Run basic commands like G28 (homing) to ensure everything works.

9. Calibration and Optimization

1. PID Tuning for Hotend:bashCopiaModificaPID_CALIBRATE HEATER=extruder TARGET=200 SAVE_CONFIG
2. Pressure Advance Calibration:
   • Improves extrusion consistency:bashCopiaModificaTUNE_PRESSURE_ADVANCE
3. Input Shaping:
   • Reduces vibrations and improves print speed:bashCopiaModificaSHAPER_CALIBRATE

---

10. Start Printing!

• Upload a test G-code file through the web interface.
• Monitor the print and enjoy the improved performance of your Ender 3 with Klipper!
