OctoPi

======

A `Raspberry Pi `_ distribution for 3d printers. It includes the `OctoPrint `_ host software for 3d printers out of the box and `mjpg-streamer with RaspiCam support `_ for live viewing of prints and timelapse video creation.



This repository contains the source script to generate the distribution out of an existing `Raspbian `_ distro image.



Where to get it?

----------------



Download the latest stable build via this button:



.. image:: https://i.imgur.com/NvUOGfS.png

   :target: https://octopi.octoprint.org/latest



Official mirror is `here `_



Second mirror is `here `_



Nightly builds are available `here `_



64bit Nightly builds are available `here `_



You can also access the nightly builds raspberrypi imager channel by running::



    rpi-imager --repo https://unofficialpi.org/rpi-imager/rpi-imager-octopi.json



or for second mirror::



    rpi-imager --repo https://octopi.gnethomelinux.com/rpi-imager/rpi-imager-octopi.json



How to use it?

--------------



#. Unzip the image and install it to an sd card `like any other Raspberry Pi image `_

#. Configure your WiFi by editing ``octopi-wpa-supplicant.txt`` on the root of the flashed card when using it like a thumb drive

#. Boot the Pi from the card

#. Log into your Pi via SSH (it is located at ``octopi.local`` `if your computer supports bonjour `_ or the IP address assigned by your router), default username is "pi", default password is "raspberry". Run ``sudo raspi-config``. Once that is open:



   a. Change the password via "Change User Password"

   b. Optionally: Change the configured timezone via "Localization Options" > "Timezone".

   c. Optionally: Change the hostname via "Network Options" > "Hostname". Your OctoPi instance will then no longer be reachable under ``octopi.local`` but rather the hostname you chose postfixed with ``.local``, so keep that in mind.

  

   You can navigate in the menus using the arrow keys and Enter. To switch to selecting the buttons at the bottom use Tab.

   

   You do not need to expand the filesystem, current versions of OctoPi do this automatically.



OctoPrint is located at `http://octopi.local `_ and also at `https://octopi.local `_. Since the SSL certificate is self signed (and generated upon first boot), you will get a certificate warning at the latter location, please ignore it.



To install plugins from the commandline instead of OctoPrint's built-in plugin manager, :code:`pip` may be found at :code:`/home/pi/oprint/bin/pip`.  Thus, an example install cmd may be:  :code:`/home/pi/oprint/bin/pip install `



If a USB webcam or the Raspberry Pi camera is detected, MJPG-streamer will be started automatically as webcam server. OctoPrint on OctoPi ships with correctly configured stream and snapshot URLs pointing at it. If necessary, you can reach it under `http://octopi.local/webcam/?action=stream `_ and SSL respectively, or directly on its configured port 8080: `http://octopi.local:8080/?action=stream `_.



Features

--------



* `OctoPrint `_ host software for 3d printers out of the box

* `Raspbian `_ tweaked for maximum performance for printing out of the box

* `mjpg-streamer with RaspiCam support `_ for live viewing of prints and timelapse video creation.



Developing

----------



Requirements

~~~~~~~~~~~~



#. `qemu-arm-static `_

#. `CustomPiOS `_

#. Downloaded `Raspbian `_ image.

#. root privileges for chroot

#. Bash

#. git

#. sudo (the script itself calls it, running as root without sudo won't work)

#. jq (part of CustomPiOS dependencies)



Build OctoPi From within OctoPi / Raspbian / Debian / Ubuntu

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~



OctoPi can be built from Debian, Ubuntu, Raspbian, or even OctoPi.

Build requires about 2.5 GB of free space available.

You can build it by issuing the following commands::



    sudo apt-get install gawk util-linux qemu-user-static git p7zip-full python3 jq

    

    git clone https://github.com/guysoft/CustomPiOS.git

    git clone https://github.com/guysoft/OctoPi.git

    cd OctoPi/src/image

    wget -c --trust-server-names 'https://downloads.raspberrypi.org/raspios_lite_armhf_latest'

    cd ..

    ../../CustomPiOS/src/update-custompios-paths

    sudo modprobe loop

    sudo bash -x ./build_dist

    

Building OctoPi Variants

~~~~~~~~~~~~~~~~~~~~~~~~



OctoPi supports building variants, which are builds with changes from the main release build. An example and other variants are available in `CustomPiOS, folder src/variants/example `_.



docker exec -it mydistro_builder::



    sudo docker exec -it mydistro_builder build [Variant]



Or to build a variant inside a container::



    sudo bash -x ./build_dist [Variant]

    

Building Using Docker

~~~~~~~~~~~~~~~~~~~~~~

`See Building with docker entry in wiki `_

    

Building Using Vagrant

~~~~~~~~~~~~~~~~~~~~~~

There is a vagrant machine configuration to let build OctoPi in case your build environment behaves differently. Unless you do extra configuration, vagrant must run as root to have nfs folder sync working.



Make sure you have a version of vagrant later than 1.9!



If you are using older versions of Ubuntu/Debian and not using apt-get `from the download page `_.



To use it::

    

    sudo apt-get install vagrant nfs-kernel-server virtualbox

    sudo vagrant plugin install vagrant-nfs_guest

    sudo modprobe nfs

    cd ../OctoPi

    git clone https://github.com/guysoft/CustomPiOS.git    

    cd OctoPi/src

    ../../CustomPiOS/src/update-custompios-paths

    cd OctoPi/src/vagrant

    sudo vagrant up

    run_vagrant_build.sh



After provisioning the machine, its also possible to run a nightly build which updates from devel using::



    cd OctoPi/src/vagrant

    run_vagrant_build.sh

    

To build a variant on the machine simply run::



    cd src/vagrant

    run_vagrant_build.sh [Variant]

    



Usage

~~~~~



#. If needed, override existing config settings by creating a new file ``src/config.local``. You can override all settings found in ``src/modules/octopi/config``. If you need to override the path to the Raspbian image to use for building OctoPi, override the path to be used in ``ZIP_IMG``. By default the most recent file matching ``*-raspbian.zip`` found in ``src/image`` will be used.

#. Run ``src/build_dist`` as root.

#. The final image will be created at the ``src/workspace``



Code contribution would be appreciated!
