Setting Up OctoPrint with the Ender 3 S1

Materials Needed:

  • Raspberry Pi (recommended models: Raspberry Pi 3B+ or 4)
  • MicroSD card (8GB or larger)
  • Power supply for Raspberry Pi
  • Webcam (optional, for monitoring and time-lapses)
  • USB cable to connect the Raspberry Pi to the Ender 3 S1


  1. Download OctoPi: OctoPi is a pre-configured Raspbian image for the Raspberry Pi with OctoPrint already installed. Download the latest version from the OctoPrint website.
  2. Flash the SD Card: Use software like Balena Etcher to flash the OctoPi image onto your MicroSD card.
  3. Configure Wi-Fi: After flashing, open the octopi-wpa-supplicant.txt file on the SD card. Edit this file to include your Wi-Fi SSID and password.
  4. Boot the Raspberry Pi: Insert the SD card into the Raspberry Pi and connect it to your network via Wi-Fi or Ethernet. Power on the Raspberry Pi.
  5. Access OctoPrint: On a device connected to the same network, open a web browser and enter http://octopi.local (or the IP address of the Raspberry Pi). Follow the setup wizard to configure OctoPrint.
  6. Connect the Ender 3 S1: Use a USB cable to connect the Raspberry Pi to the Ender 3 S1. In OctoPrint, navigate to the connection settings and select the appropriate serial port and baud rate (usually 115200).
  7. Install Plugins: Explore the Plugin Manager in OctoPrint to find and install plugins that suit your needs. Popular plugins include OctoLapse, Bed Level Visualizer, and Dashboard.

Tips for Optimizing Your OctoPrint Setup

Use a Reliable Power Supply: Ensure your Raspberry Pi has a stable power supply to prevent unexpected shutdowns.

Optimize Webcam Settings: If using a webcam, adjust the resolution and frame rate for a balance between quality and performance.

Secure Your Setup: Set up access controls and consider enabling HTTPS to secure your OctoPrint interface from unauthorized access.

Monitor System Resources: Keep an eye on the Raspberry Pi’s CPU and memory usage, especially if running multiple plugins. Upgrade to a Raspberry Pi 4 if needed for better performance.

Regular Maintenance: Keep your OctoPrint software and plugins up to date to benefit from the latest features and security improvements.

Advanced Features and Plugins

OctoLapse: Create smooth and professional time-lapse videos of your prints. Configure the plugin to take snapshots at specific intervals or layer changes without affecting print quality.

Bed Level Visualizer: Use this plugin to visualize your print bed’s levelness. It helps in fine-tuning the bed leveling process for optimal print adhesion.

Themeify: Customize the look and feel of your OctoPrint interface with custom themes and styles.

Filament Manager: Keep track of your filament usage, inventory, and remaining length. Set up notifications for low filament conditions.

Print Time Genius: Improve the accuracy of OctoPrint’s print time estimates by analyzing your G-code files in detail.
