The Tevo Tarantula, a popular DIY 3D printer, provides a fantastic entry point into the world of additive manufacturing. However, like any machine, its performance can be enhanced. One of the most impactful upgrades you can make is replacing the main board. This comprehensive guide will walk you through everything you need to know about upgrading your Tevo Tarantula main board, from understanding its components to troubleshooting common issues. This upgrade can significantly improve print quality, speed, and overall reliability. Let’s dive in and unlock the full potential of your 3D printer.
Understanding Your Tevo Tarantula Main Board
Before you begin the upgrade process, it’s crucial to understand the main board itself. The main board acts as the central control unit of your 3D printer, managing all the critical functions necessary for printing. It receives instructions from the host computer or SD card, controls the stepper motors, heats the bed and nozzle, and manages the overall operation of the printer. The main board is responsible for translating G-code instructions into physical movements and actions, making it the brain of your 3D printing operations. Understanding its role is fundamental for successful upgrades and maintenance.
Identifying the Main Board
The main board is typically located within the base of your Tevo Tarantula, often housed inside an enclosure for protection. To identify it, you’ll need to open the base and locate the circuit board with numerous connectors for stepper motors, endstops, the heated bed, the hotend, and the power supply. The main board is usually a rectangular printed circuit board (PCB) with various electronic components such as microcontrollers, drivers, and terminals. Refer to your printer’s manual if you’re unsure where to look or what to expect. Remember to disconnect the power supply before accessing the main board.
Components of the Main Board
The main board comprises several key components that work in concert to manage the printer’s functions. These components include a microcontroller, such as an Arduino Mega, which is the processing unit of the board; stepper motor drivers that control the movement of the motors; MOSFETs that manage the power to the heated bed and hotend; and various connectors for endstops, thermistors, LCD screens, and other peripherals. These components allow the printer to translate digital instructions into physical actions, controlling temperature, movement, and overall printer behavior. Understanding these components will help in troubleshooting any future issues. (Image tevo-tarantula-main-board-components.webp)

Consider your needs and preferences carefully, evaluating aspects such as features, capabilities, and upgrade options. Making an informed choice will lead to a satisfying upgrade experience.
Factors to Consider
When selecting a new main board, consider factors such as the microcontroller type, the number of stepper motor drivers, the types of drivers used (e.g., TMC2208, TMC2209), the availability of features like auto-bed leveling support, and the board’s overall processing power. Also, assess your existing accessories and planned upgrades, making sure the new board supports them. Consider the firmware compatibility as well, whether it uses Marlin, Klipper, or another firmware. Consider the community support and documentation for easy setup and troubleshooting.
Compatibility Check
Before purchasing a new main board, check its compatibility with your Tevo Tarantula. Ensure that the new board has the necessary connectors and pinouts to match your existing components, such as the stepper motors, endstops, thermistors, and heated bed. Review the specifications of the new board to confirm that it supports your existing power supply and voltage requirements. If you plan to add any additional features or accessories, verify that the new board has the required ports and connections. Contacting the manufacturer or seeking online advice can help you ensure a smooth, trouble-free upgrade process. Also, you can compare photos of your current board with the new one.
