Download & Setup OctoPrint
- OctoPrint plus its dependencies
- MJPG-Streamer for live viewing of prints and timelapse video creation, compatible with various USB webcams and the Raspberry Pi camera
Recommended hardware: Raspberry Pi 3B.
Please note that the Raspberry Pi Zero W is not recommended since severe performance issues were observed, caused by the WiFi interface when bandwidth is utilized (e.g. the webcam is streamed), negatively impacting printing results. See also here.
You can download the latest OctoPi image via the following button.
Image compatible with Raspberry Pi A, B, A+, B+, 2B, 3A+, 3B, 3B+, 4B, Zero and Zero W.
Raspberry Pi 3B or 3B+ strongly recommended!
or simply buy one of the available
Setting up OctoPi
Please follow these steps after downloading:
Unzip the image and install the contained
.imgfile to an SD card using Etcher. Do not at any point format the SD from your Operating System, even if prompted to do so - that will break it and you’ll have to start over. Just use Etcher to flash the
.imgfile, that is enough!
Configure your WiFi connection by editing
octopi-wpa-supplicant.txton the root of the flashed card when using it like a thumb drive. Important: Do not use WordPad (Windows) or TextEdit (MacOS X) for this, those editors are known to mangle the file, making configuration fail. Use something like Notepad++, Atom or VSCode instead or at the very least heed the warnings in the file.
Note: This changed with OctoPi 0.15.0, earlier versions had you edit
octopi-network.txtwhich has a different format. This old method is no longer supported and the contents of this file will be ignored. Just use
Please also refer take a look at the full WiFi setup guide in the FAQ that also includes Troubleshooting tips.
Boot the Pi from the card.
Log into your Pi via SSH (it is located at
octopi.localif 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:
- Change the password via “Change User Password”
- Optionally: Change the configured timezone via “Localization Options” > “Timezone”.
- Optionally: Change the hostname via “Network Options” > “Hostname”. Your OctoPi instance will then no longer be reachable under
octopi.localbut 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.
You also do not need to manually enable the RaspiCam if you have one, that is already taken care of on the image as well.
Access OctoPrint through
http://<your pi's ip address>. https is available too, with a self-signed certificate (which means your browser will warn you about it being invalid).
Thomas Sanladerer created a great video guide on how to get OctoPi 0.12 up an running.
- The MagPi issue #36 contains a “Getting Started” guide on pages 50-51. You can find an excerpt here (MagPi License: CC BY-NC-SA).
- Scripts to build (and customize) the image yourself can be found in OctoPi’s Github repository.
- Nightly builds can be found here.
The generic setup instructions boil down to
- Installing Python 2.7 including pip and virtualenv.
- Creating a virtual environment somewhere:
- Installing OctoPrint into that virtual environment:
OctoPrint/bin/pip install OctoPrint
- OctoPrint may then be started through
./OctoPrint/bin/octoprint serveor with an absolute path
More specific setup instructions for the most common runtime environments can be found below.
For installing OctoPrint from source, please take a look at the setup instructions for Raspbian on the forum. They should be pretty much identical on other Linux distributions.
For installing the OctoPrint server on a Windows system, please take a look at the setup instructions for Windows on the forum.
For installing the OctoPrint server on a Mac, please take a look at the setup instructions for MacOS on the forum.
