There are three ways to install OctoPrint on a Raspberry Pi:
  - Our Customized OctoPi
  - guysoft/OctoPi
  - Install OctoPrint from source on a Raspberry Pi.

----

 =====Our Customized OctoPi=====
This is the easiest way to use OctoPrint on a Raspberry Pi\\
====1.Download Image====
[[https://github.com/WEEDO3DTECH/OctoPi/releases/download/v1.8.6/2022-09-22-raspios-bullseye-armhf-lite-eww.xz|Download our custom version of OctoPi]] .\\
====2.Install image tool====
Download the latest version of [[https://www.raspberrypi.com/software/|Raspberry Pi Imager]] and install it. \\
====3.Flash image====
Then:
  *Connect an SD card reader with the SD card inside.
  *Open Raspberry Pi Imager and choose the Customized OctoPi.{{:octoprint:0chose-image.png?400|}}{{:octoprint:1flash-image.png?400|}}
  *Choose the SD card you wish to write your image to.
  *Review your selections and click on the Write button to begin writing data to the SD Card.
====4.Connect Printer====
Select X40 from the "Printer Profile" settings, and connect the printer with 115200 baud rate.

=====guysoft/OctoPi=====
The latest version of [[https://github.com/guysoft/OctoPi|OctoPi]] is 0.18.0 released on Jan 25, 2021. This version of OctoPi needs to update the serial driver of ch340/ch341.

====1.Install Image====
Unzip the guysoft/OctoPi image and install it to an sd card according to the installation instructions of guysoft/OctoPi.

====2.Login====
Log into your pi via SSH or other means\\ {{:octoprint:2login.png?400|}}

====3.Delete the older ch340/ch341 serial driver==== 
Check if the ch340/ch341 serial driver already exists：\\
  ls /lib/modules/$(uname -r)/kernel/drivers/usb/serial/
Delete it:\\
  sudo rm /lib/modules/$(uname -r)/kernel/drivers/usb/serial/ch341.ko
{{:octoprint:3delete-driver.png?400|}}\\

====4.Build the newer serial driver and install it:====

===a)Install the Linux kernel header file:===
The Linux kernel version of OctoPi V0.18.0 is 5.4.79, so we download the corresponding header file installation package.
  wget http://archive.raspberrypi.org/debian/pool/main/r/raspberrypi-firmware/raspberrypi-kernel-headers_1.20201126-1_armhf.deb 
（If your Linux kernel version is not 5.4.79, download the corresponding one from http://archive.raspberrypi.org/debian/pool/main/r/raspberrypi-firmware/ ; \\
Use this command to check which version of your Linux kernel is: **uname -r**）\\
\\
Install the header file :
  sudo dpkg -i ./raspberrypi-kernel-headers_1.20201126-1_armhf.deb
{{:octoprint:4install-header.png?400|}}

===b)Download the CH340/CH341 serial driver source code and unzip it===
  wget http://www.weedo3dprinter.com/lib/exe/fetch.php/firmware/ch341ser_linux-kernel5.4.79.zip
  unzip ch341ser_linux-kernel5.4.79.zip
{{:octoprint:5download-source.png?400|}}

===c)Build it:===
  cd ch341ser_linux-kernel5.4.79 && make
{{:octoprint:6build.png?400|}}

===d)Install it:===
  sudo cp ch34x.ko /lib/modules/$(uname -r)/kernel/drivers/usb/serial/
  sudo depmod
{{:octoprint:7copy.png?400|}}

====5.Reboot your Raspberry Pi and Connect the printer with its baud rate====
===a)Reboot your Raspberry Pi, then add X40 settings to the profile.===
{{:octoprint:x40-octoprint-settings_1_.png?400|}}
{{:octoprint:x40-octoprint-settings_2_.png?400|}}
{{:octoprint:x40-octoprint-settings_3_.png?400|}}
{{:octoprint:x40-octoprint-settings_4_.png?400|}}

===b)Connect printer with 115200 baud rate===
{{:octoprint:x40-octoprint-connect.png?600|}}\\

=====Install OctoPrint from source on a Raspberry Pi=====
This installation method is a bit complicated, if you do not have programming skills, we do not recommend you to use this method.
====1.Install OctoPrint====
Install OctoPrint following the [[https://community.octoprint.org/docs|OctoPrint community documents]].\\
\\
**If you can connect the printer by baud rate 115200**, skip to section 3.\\
\\
**If you can not connect the printer with OctoPrint**, continue with section 2 to update the serial driver of CH341:
====2.Update serial driver====
===a)Update your Linux kernel===
  sudo apt-get update
  sudo apt-get install raspberrypi-bootloader raspberrypi-kernel
  sudo reboot
===b)Install your Linux kernel header package===
  sudo apt install raspberrypi-kernel-headers
===c)Download the CH340/CH341 serial driver source code and unzip it===
  wget http://www.weedo3dprinter.com/lib/exe/fetch.php/firmware/ch341ser_linux-kernel5.4.79.zip
  unzip ch341ser_linux-kernel5.4.79.zip
{{:octoprint:5download-source.png?400|}}

===d)Build it:===
  cd ch341ser_linux-kernel5.4.79 && make
{{:octoprint:6build.png?400|}}

===e)Install it:===
  sudo cp ch34x.ko /lib/modules/$(uname -r)/kernel/drivers/usb/serial/
  sudo depmod
{{:octoprint:7copy.png?400|}}\\

====3.Reboot your Raspberry Pi and connect the printer with its baud rate====
===a)Reboot your Raspberry Pi, then add X40 settings to the profile.===
{{:octoprint:x40-octoprint-settings_1_.png?400|}}
{{:octoprint:x40-octoprint-settings_2_.png?400|}}
{{:octoprint:x40-octoprint-settings_3_.png?400|}}
{{:octoprint:x40-octoprint-settings_4_.png?400|}}

===b)Connect printer with 115200 baud rate===
