Klippo Installation

Requirements

  • Raspberry pi 4 (raspberry pi 3 is not tested, and may require different GL driver settings in kgui/__init__.py)
  • One of the supported touchscreens:
    • Official Raspberry pi 7" touchscreen 800x480
    • Chinese 7" 1024x600 touchscreens. These screens can be purchased for around 35$ on Aliexpress, Ebay, or Banggood. Make sure to get one with an IPS panel (much better image quality)

Prepare OS

  • Flash Raspberry Pi OS lite 2021-01-11 to SD-Card
  • Add new file named "ssh" (with no file extension) to the boot folder to enable ssh
  • Boot your pi and run the following commands via SSH
  • An ethernet connection is currently necessary during the installation (installing wifi dependencies disconnects any wifi connection, terminating the ssh session)
sudo apt update
sudo apt install git
sudo raspi-config
  • Set following raspi-config options:
    • Advanced Options -> GL Driver to GL (Fake KMS) (confirm installation of additional drivers with Y)
    • System Options -> Boot / Auto Login to Console Autologin
    • Interface Options -> Camera to enabled (If you plan to use a raspi-cam)
    • Localisation Options -> Locale: Add your local Locale (UTF8 version) as well as en_GB.UTF8 UTF-8 by selecting with the spacebar, confirm and set en_GB.UTF8 UTF-8 as default.
  • (If the Pi fails to boot, try briefly disconnecting the printer mainboards USB cable)

Installation

cd ~

git clone -b stable https://github.com/D4SK/klippo

./klippo/scripts/install-klippo-x11.sh
  • Run the Cura Connection install script when using cura connection (recommended)
~/klippo/klippy/parallel_extras/cura_connection/install.sh

  • If you haven't flashed your printer-mainboards firmware yet follow klipper/Installation.md (Building and flashing the micro-controller)

  • Move your printer configuration (printer.cfg) to /home/pi and add the necessary sections

  • Change the resolution in the kivy config according to the screen you are using. (default is 1024x600) E.g. "height = 800" and "width = 480" nano ~/klippo/klippy/parallel_extras/kgui/config.ini

  • If the UI appears upside down, rotate your screen. Alternatively you can change some parameters in the ~/.kivy/config.ini file. In the [graphics] section set rotation=90 to rotation=270 and in the [input] section set rotation=0 to rotation=2

  • Reboot sudo reboot

# Provide these Gcode macros when using filament_manager.
# The FORCE parameter is needed for all G1 moves to
# avoid "Extrude below minimum temp" and "Extrude only move too long" errors.
# This is an example for a bowden printer with 600mm tube length.
