How to install klipper - markniu/PandaPi GitHub Wiki
For PandaPI board(>=V2.8 2012/3),Schematic
Prepping an OS image
After Flashing OS image, it will be necessary to ssh into the target machine to run a handful of system commands. If using a Linux or MacOS desktop, then the “ssh” software should already be installed on the desktop. There are free ssh clients available for other desktops (eg,secureCRT, PuTTY). Use the ssh utility to connect to the Raspberry Pi (ssh pi@octopi – password is “raspberry”) and run the following commands:
git clone https://github.com/KevinOConnor/klipper
sudo nano ./klipper/scripts/install-octopi.sh
and comment the line # sudo apt-get update in the install-octopi.sh,and save.
./klipper/scripts/install-octopi.sh
The above will download Klipper, install some system dependencies, setup Klipper to run at system startup, and start the Klipper host software. It will require an internet connection and it may take a few minutes to complete.
if there is error like this:
dpkg: unrecoverable fatal error, aborting:
files list file for package 'nodejs' is missing final newline
please run
sudo mv /var/lib/dpkg/info/nodejs.list .
and then try again.
Building and flashing the micro-controller
- To compile the micro-controller code, start by running these commands on the Raspberry Pi:
cd ~/klipper/
make menuconfig
Select the appropriate micro-controller and review any other options provided.
Once configured, run:
make
Flashing the micro-controller
Configure the hardware with jumppers and line (you can remove that yellow line after flashing which is only used for resetting mcu when flashing)
then open browser enter http://your_raspberryPI_IP:8181, click the "Run Klipper mode",it will flashing the MCU
Configuring OctoPrint to use Klipper
The OctoPrint web server needs to be configured to communicate with the Klipper host software. Using a web browser, login to the OctoPrint web page and then configure the following items:
Navigate to the Settings tab (the wrench icon at the top of the page). Under “Serial Connection” in “Additional serial ports” add “/tmp/printer”. Then click “Save”.
Enter the Settings tab again and under “Serial Connection” change the “Serial Port” setting to “/tmp/printer”.
In the Settings tab, navigate to the “Behavior” sub-tab and select the “Cancel any ongoing prints but stay connected to the printer” option. Click “Save”.
From the main page, under the “Connection” section (at the top left of the page) make sure the “Serial Port” is set to “/tmp/printer” and click “Connect”. (If “/tmp/printer” is not an available selection then try reloading the page.)
Once connected, navigate to the “Terminal” tab and type “status” (without the quotes) into the command entry box and click “Send”. The terminal window will likely report there is an error opening the config file - that means OctoPrint is successfully communicating with Klipper. Proceed to the next section.
Configuring Klipper
nano ~/printer.cfg
copy the following to the printer.cfg.
after that run sudo service klipper restart restart klipper
