Klipper

Installation

The following commands will clone Klipper to an appropriate directory in HOME and run the setup script.

cd ~
git clone https://github.com/KevinOConnor/klipper
cd ~/klipper
./scripts/install-octopi.sh

Configuration

After Klipper is installed, you will need to change the default location of the printer.cfg and add the UDS (unix domain socket). This is defined in the file /etc/default/klipper

To edit this file type:

sudo nano /etc/default/klipper

find the following line:

KLIPPY_ARGS="/home/pi/klipper/klippy/klippy.py /home/pi/printer.cfg -l /tmp/klippy.log"

and change the config location to /home/pi/klipper_config/printer.cfg and add -a /tmp/klippy_uds to define UDS.

KLIPPY_ARGS="/home/pi/klipper/klippy/klippy.py /home/pi/klipper_config/printer.cfg -l /tmp/klippy.log -a /tmp/klippy_uds"

Save the file with CTRL+O and close the editor with CTRL+X.

You have to create the directories for your klipper configuration and the virtual_sdcard directory:

mkdir ~/klipper_config
mkdir ~/gcode_files

Move your printer.cfg to ~/klipper_config and check if the following entries are present in the config.

[virtual_sdcard]
# for gcode upload
path: ~/gcode_files

[display_status]
# for display messages in status panel

[pause_resume]
# for pause/resume functionality. 
# Mainsail needs gcode macros for `PAUSE`, `RESUME` and `CANCEL_PRINT` to make the buttons work.

These entries are very important.
For the full functionality of mainsail, you should also define gcode macros for PAUSE, RESUME and CANCEL_PRINT. You’ll find further information in this document.

After your config is in place, restart klipper with sudo service klipper restart. Check the /tmp/klippy.log for errors, if Klipper starts correctly you can continue the guide.
