A Step-by-Step Guide to Installing OctoPrint on a Raspberry Pi

OctoPrint is a powerful open-source software that allows you to remotely monitor and control your 3D printer. By installing OctoPrint on a Raspberry Pi, you can gain enhanced functionality and convenience while managing your printing projects. In this article, we will provide a detailed guide on how to install OctoPrint on a Raspberry Pi, enabling you to streamline your 3D printing workflow.

Requirements: Before we begin, make sure you have the following:

  1. Raspberry Pi (preferably model 3 or later)
  2. MicroSD card (8GB or larger)
  3. Power supply for the Raspberry Pi
  4. USB cable for connecting the Raspberry Pi to your 3D printer
  5. Ethernet cable or Wi-Fi connectivity for internet access

Step 1: Prepare the Raspberry Pi

  1. Insert the microSD card into your computer.
  2. Download the latest version of Raspberry Pi OS Lite (headless) from the official Raspberry Pi website.
  3. Use a tool like BalenaEtcher to flash the Raspberry Pi OS Lite image onto the microSD card.
  4. Eject the microSD card safely from your computer.

Step 2: Initial Setup

  1. Insert the microSD card into the Raspberry Pi.
  2. Connect the Raspberry Pi to your 3D printer using the USB cable.
  3. Connect the power supply to the Raspberry Pi to turn it on.
  4. Wait for the Raspberry Pi to boot up and establish a network connection.

Step 3: Install OctoPrint

  1. Open a terminal on your computer and establish an SSH connection to the Raspberry Pi. Use the default credentials (username: “pi,” password: “raspberry”).
  2. Once connected, run the following command to update the Raspberry Pi OS:

sudo apt-get update && sudo apt-get upgrade

After the update is complete, install the necessary dependencies by running the following command:

sudo apt-get install python-pip python-dev python-setuptools python-virtualenv git libyaml-dev build-essential

Create a virtual environment for OctoPrint by executing the following commands:

mkdir ~/OctoPrint && cd ~/OctoPrint

virtualenv venv

source venv/bin/activate

Install OctoPrint by running the following command:

pip install OctoPrint

Step 4: Configure OctoPrint

  1. Generate a configuration file for OctoPrint by running the following command:

octoprint –init-config

Open the configuration file in a text editor using the command:

nano ~/.octoprint/config.yaml

  1. Customize the configuration to your preference, including Wi-Fi settings, camera settings, and printer-specific configurations.
  2. Save the changes and exit the text editor (Ctrl+X, Y, Enter).

Step 5: Launch OctoPrint

  1. Start the OctoPrint server by running the following command:

octoprint serve

Open a web browser on your computer and enter the IP address of your Raspberry Pi, followed by “:5000” (e.g.,

You will be directed to the OctoPrint setup wizard. Follow the on-screen instructions to complete the initial setup, including creating a login password and adding your printer.

Once the setup is complete, you will have access to the OctoPrint web interface, allowing you to monitor and control your 3D printer remotely.
