Calibrating Your 3D Printer
After installing and configuring Marlin firmware, calibrating your 3D printer is essential. Calibration ensures that your printer can accurately and consistently produce high-quality prints. The calibration process involves several steps, including bed leveling, setting the Z-offset, calibrating the extruder, and fine-tuning the PID values for the hotend and heated bed. Start by carefully leveling the print bed to ensure the first layer of your print adheres correctly. After that, set the Z-offset, which determines the distance between the nozzle and the print bed when printing the first layer. Calibrating the extruder helps to ensure the correct amount of filament is extruded. The PID tuning optimizes the temperature control for your hotend and heated bed. Properly calibrating your printer will significantly improve print quality and overall printing success.
Leveling the Bed
Leveling the print bed is an essential part of the calibration process. A level bed ensures that the first layer of your print adheres to the bed and is consistent across the entire print area. There are several methods for leveling the bed. The manual method involves adjusting the bed leveling screws at each corner while using a piece of paper between the nozzle and the bed. The goal is to achieve a slight resistance when pulling the paper. If your printer has auto-bed leveling (ABL), the process is typically automated. The ABL system measures the bed’s surface and compensates for any unevenness. Regardless of the method used, perform multiple leveling checks to ensure accuracy. A poorly leveled bed can lead to warped prints, poor adhesion, and nozzle damage. It’s important to repeat this step if you change the bed surface or nozzle height.
Setting the Z-Offset
After leveling the bed, set the Z-offset correctly. The Z-offset determines the distance between the nozzle and the bed when the printer starts printing. If the Z-offset is incorrect, the nozzle will be either too close or too far from the bed. If the nozzle is too close, it can scrape the bed, causing a blockage of the nozzle. If the nozzle is too far, the first layer won’t stick to the bed. Adjust the Z-offset during printing while observing the first layer. Many printers have a setting to adjust the Z-offset in real-time through the control panel. Make small adjustments and observe the results until the first layer adheres to the bed smoothly and evenly. Getting the Z-offset right is important for print quality and adhesion. A well-calibrated Z-offset makes a big difference in your prints, leading to clean lines and fewer errors.
Testing the Firmware
After you have successfully uploaded the Marlin firmware and completed the basic calibration, it’s time to test the firmware. The best way to test your firmware is by printing a test model. Start with a small, simple model, such as a calibration cube or a bed adhesion test. Monitor the print closely during the first few layers to ensure the printer is functioning correctly. Check for issues like bed adhesion problems, extrusion problems, and incorrect temperature readings. If you find any issues, go back and check your configurations. Examine each axis movement to confirm that they are working as expected. It’s important to do these tests to make sure everything is working properly before you start your more complex printing projects. Testing helps uncover any potential problems and allows you to fine-tune the settings for better print quality.
Uploading the Firmware to Your Tevo Tarantula
Uploading the firmware to your Tevo Tarantula is a crucial step that puts all your hard work into action. Connect your printer to your computer using a USB cable. In the Arduino IDE, select the correct board and port from the ‘Tools’ menu. Verify the settings before proceeding with the upload. Then, click the upload button (usually an arrow icon) in the IDE. The IDE will compile the code and upload the firmware to your printer’s mainboard. Watch the IDE’s output window for any error messages, as they can indicate problems with your configuration. If the upload is successful, the printer’s control panel or LCD screen may change or display information about the new firmware. If the upload fails, check the connection, the board settings, and the drivers. Once the upload is complete, reset your printer to initialize the new firmware settings.
Verifying Firmware Installation
After uploading the firmware, you must verify its successful installation. Check the printer’s control panel or LCD screen for any signs of the new firmware. The display might show the firmware version or other information. Try moving the axes and testing the heating functions to ensure they function as intended. If the printer has auto-bed leveling, activate the feature to verify its operation. Run a simple print to confirm all the features work as expected. If you notice that some settings or features you enabled in the configuration.h file aren’t working, double-check the configuration to ensure the settings are correct and re-upload the firmware. Make sure the printer responds to commands and that the movements are accurate. Verifying the firmware installation is critical for ensuring all settings are working correctly and preventing errors during printing.

Testing and adjusting each setting one by one can help you find the source of the problem.
Dealing With Bed Adhesion Problems
Bed adhesion problems are among the most frequent issues in 3D printing. If the first layer doesn’t stick to the bed, the print will likely fail. Some common causes include bed leveling issues, incorrect Z-offset settings, and insufficient bed temperature. To address these problems, level the bed carefully and adjust the Z-offset for perfect first-layer adhesion. Make sure your bed temperature settings are appropriate for the material you are using. Ensure the bed surface is clean and free from grease or dust. Using a bed adhesive like glue stick, hairspray, or painter’s tape can improve adhesion. Experiment with different bed surfaces to find the best adhesion for your materials. By understanding and resolving adhesion problems, you can ensure prints will stay on the bed throughout the entire printing process.
Addressing Extrusion Issues
Extrusion issues result in inconsistent filament flow and can severely impact print quality. Common extrusion problems include under-extrusion (not enough filament) and over-extrusion (too much filament). Under-extrusion can be caused by a clogged nozzle, incorrect extruder settings, or low hotend temperature. Over-extrusion can be caused by incorrect settings. Adjust the nozzle temperature and filament flow settings to improve extrusion. Regularly clean the nozzle to prevent clogs. The extruder motor’s e-steps/mm setting must be calibrated correctly. If the problem persists, inspect the extruder itself for any mechanical problems. Ensure the filament is dry. Correcting extrusion problems will result in smooth, detailed prints and help you achieve the best results on your Tevo Tarantula.
Adjusting Firmware Settings for Improved Printing
Fine-tuning your Marlin firmware settings is essential for achieving high-quality prints. There are many settings you can adjust to improve print quality, printing speed, and overall performance. Settings related to temperature control for the hotend and heated bed are critical. The PID values can be calibrated to optimize temperature stability. Speed and acceleration settings impact the speed at which your printer can move and print. Linear advance is a helpful setting for improving print quality by compensating for the pressure buildup in the nozzle. Experiment with different settings and make small adjustments to optimize your printer. Keeping logs of the settings you modify can make it easier to revert if needed. Fine-tuning settings requires time and patience, but it can significantly improve your prints and give you more control over your 3D printer.
