Recommended hardware: Raspberry Pi 3B, 3B+ or 4B. Expect print artifacts and long loading times with other options, especially when adding a webcam or installing third party plugins. Setups not using recommended hardware are not officially supported.
Please note that the Raspberry Pi Zero W is not recommended explicitly since severe performance issues were observed, caused by the WiFi interface when bandwidth is utilized (e.g. the webcam is streamed), negatively impacting printing quality. See also here.
You can download the latest OctoPi image via the following button. Download OctoPi 0.17.0MD5Sum of the .zip:

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
octopi-wpa-supplicant.txt.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.
- 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).
