For updating firmware, download the firmware file and follow the manufacturer’s instructions for flashing it to your printer’s control board using software like Arduino IDE.
Flashing the Bootloader (Optional)
Flashing a bootloader can simplify firmware updates, allowing you to upload new firmware without needing an ISP programmer. While not strictly required for OctoPrint, having a bootloader can streamline your workflow. The process involves using an ISP programmer to flash the bootloader onto your printer’s microcontroller. This allows you to upload firmware via USB without needing specialized hardware in the future. The ability to update firmware quickly and easily will be beneficial for integrating and maintaining OctoPrint.
Setting Up OctoPrint on Raspberry Pi

OctoPrint typically runs on a Raspberry Pi, a small, affordable computer. This setup provides a dedicated platform for OctoPrint, allowing it to run independently of your primary computer. Choose a Raspberry Pi model that meets your needs, with the Raspberry Pi 3 B+ or later recommended for optimal performance. A Raspberry Pi allows you to control and monitor your printer from anywhere on your network. The Raspberry Pi should have enough processing power and memory to manage the demands of the 3D printing process. Once the Raspberry Pi is set up, it can connect to your home network, enabling remote access and monitoring.
Raspberry Pi Configuration for OctoPrint
Begin by installing the Raspberry Pi OS on an SD card. You can use the Raspberry Pi Imager tool for this purpose. Ensure you enable SSH and configure your Wi-Fi settings during the setup process. After the initial setup, update your Raspberry Pi to the latest software packages. These steps will ensure that your Raspberry Pi is ready to support OctoPrint. Once the OS is installed, you should configure the network settings to allow communication with your local network and access to the internet, essential for OctoPrint’s functionalities.
Downloading and Flashing OctoPrint
OctoPrint can be installed using a variety of methods, but the most straightforward approach is to flash the OctoPi image onto your SD card. OctoPi is a pre-configured Raspberry Pi image with OctoPrint and all its dependencies pre-installed. This simplifies the setup process. Download the latest OctoPi image and use a tool like Etcher to flash it to your SD card. This will save time and ensure that all the required software is ready to go. After flashing, insert the SD card into your Raspberry Pi and boot it up.
Accessing OctoPrint for the First Time

After booting your Raspberry Pi with OctoPrint, find its IP address on your network. You can usually find this in your router’s settings or by using a network scanner. Open a web browser and enter the IP address followed by :5000 (e.g., 192.168.1.100:5000). This will take you to the OctoPrint interface. The first time you access OctoPrint, you’ll be prompted to set up an account and configure basic settings. Verify that you can access the OctoPrint interface from any device on your network. This confirms that your Raspberry Pi and OctoPrint are accessible and correctly configured.
Configuring OctoPrint Settings for Tevo Tarantula
Within OctoPrint, navigate to the settings menu. This is where you’ll configure your printer’s specific details. Start by setting up your printer profile. The correct printer profile is crucial for OctoPrint to communicate with your Tevo Tarantula. You will need to provide information about the printer’s bed size, axes, and extruder configuration. Incorrect settings can lead to printing errors or damage your printer. Configuring these settings ensures that OctoPrint knows the physical dimensions of your printer and how to control its movements.
Printer Profile Setup in OctoPrint
When setting up your printer profile, select the Tevo Tarantula from the list of pre-configured profiles if available, otherwise, you can manually enter the settings. Enter the bed size (X, Y dimensions) and the maximum printing height (Z dimension) accurately. Next, configure the axes, including the movement speeds for each axis. Correctly configuring these settings is important for precise control during printing. Provide accurate settings for your specific Tevo Tarantula model, including travel speeds and acceleration settings.
Bed Size, Axes and Extruder Settings

Carefully enter the bed dimensions (X, Y), typically 200x200mm for the Tevo Tarantula. The maximum print height (Z) should also be entered, usually around 180mm. Regarding the extruder, specify the nozzle diameter and the type of filament you plan to use. These settings are critical for the proper slicing and printing of your models. Correct settings ensure the printer moves correctly and the material extrudes at the proper rate. Accurate setup will help prevent common issues such as bed adhesion problems or incorrect layer heights.
Connecting OctoPrint to Your 3D Printer
Connect your Tevo Tarantula to the Raspberry Pi using a USB cable. In OctoPrint, go to the ‘Connection’ tab and select the correct serial port and baud rate. The baud rate is critical for proper communication, so ensure it matches your printer’s configuration. If the printer isn’t connecting, try different baud rates until you find the correct one. Once connected, the OctoPrint interface should display information about your printer, such as its current temperature and status. Ensure that the USB cable is securely connected to both your printer and the Raspberry Pi. The selected serial port and baud rate must match your printer’s settings.
