Consider using online resources or guides tailored to the Tevo Tarantula for the best configuration specifics. Save the configuration files after making adjustments.
Connect Your Tevo Tarantula to Your Computer
To upload the configured Marlin firmware, connect your Tevo Tarantula to your computer using a USB cable. Ensure the printer is powered off initially, then connect the USB cable to the printer’s control board and a USB port on your computer. Once connected, turn on the Tevo Tarantula, and the computer should recognize the device. If the printer isn’t automatically recognized, you might need to install the correct drivers. These drivers often come with the Arduino IDE or can be found online. In the Arduino IDE, select the correct board (usually an Arduino Mega or similar, depending on your control board) and the correct COM port under the ‘Tools’ menu. Verifying the correct board and port selection is essential for a successful firmware upload. Incorrect settings will lead to uploading failure, so double-check everything before proceeding.
Upload the Firmware to Your 3D Printer
With your printer connected and the Arduino IDE set up, it’s time to upload the compiled Marlin firmware to your Tevo Tarantula. In the Arduino IDE, click the ‘Upload’ button. The IDE will compile the firmware, and if there are no errors, it will start uploading it to the printer’s control board. Watch the progress bar at the bottom of the IDE window during the upload process; this will indicate the upload’s status. It might take a few minutes to complete. If the upload is successful, you’ll see a ‘Done uploading’ message in the IDE. If you encounter errors, carefully review the error messages and address any problems with your code. Common issues include incorrect board selection or COM port settings. Once the upload completes, your Tevo Tarantula should now be running the new Marlin firmware.
Configuring Marlin Firmware Settings
After uploading Marlin, the settings need to be configured for your specific printer. This is usually done through the printer’s LCD screen or by sending G-code commands from a computer. Through the printer’s menu, you can access options to calibrate the Z-offset, set the steps per millimeter for the axes, and adjust temperature settings. You can also use a host software like Pronterface or OctoPrint to send G-code commands to the printer. These commands provide more granular control over the printer’s functions and allow you to adjust the settings in real-time. Experiment with these settings to fine-tune your printer. For example, calibrating the Z-offset correctly is crucial for the first layer adhesion. Carefully adjust all settings until you achieve satisfactory results.
Bed Leveling
Bed leveling is a crucial part of the setup process. Marlin firmware offers several methods for bed leveling, including manual bed leveling, assisted bed leveling, and automatic bed leveling (ABL). Manual bed leveling involves adjusting the bed’s height at several points using screws. Assisted bed leveling involves using the printer’s endstops to assist in the leveling process. With ABL, a sensor automatically measures the bed’s surface at multiple points and compensates for any irregularities. Implement ABL by installing a sensor, and then calibrating it within the Marlin firmware’s configuration settings. After the leveling process, carefully check the first layer print. It should adhere properly to the bed, with the filament being pressed slightly onto the surface, to achieve optimal results.
Setting Up the Z-Offset
The Z-offset setting, especially important when using ABL, determines the distance between the nozzle and the bed surface at the Z=0 position. This is necessary for proper first-layer adhesion. If the Z-offset is too high, the filament won’t stick to the bed; if it’s too low, the nozzle will drag across the bed, potentially causing damage. To set the Z-offset, home the printer, and move the nozzle close to the bed. Use a piece of paper as a guide to find the correct distance. Adjust the Z-offset setting in the firmware or through the printer’s menu, saving your adjustments. Fine-tune the Z-offset while printing a test square, ensuring the first layer is smooth and properly adhered. Continuous calibration ensures perfect first layers.
Testing and Troubleshooting
Once you’ve configured the settings, it’s important to test your Tevo Tarantula with the new Marlin firmware. Start by printing a small test model, such as a calibration cube or a simple geometric shape. Monitor the print closely, paying attention to the first layer adhesion, the overall print quality, and the dimensional accuracy of the print. While printing, check that the hotend and bed temperatures remain constant, and the movement of the axes is smooth and consistent. If you notice any issues such as poor layer adhesion, warping, or extruder problems, take notes and address them. This step lets you find and correct minor adjustments before printing a larger model. The test will help to identify potential issues. Keep in mind to always watch the first layer.
Common Issues and Solutions
You might encounter various issues when setting up and using Marlin firmware on your Tevo Tarantula. One common problem is print adhesion issues, which are often due to incorrect bed leveling or Z-offset settings. Solutions include ensuring the bed is properly leveled, adjusting the Z-offset, and cleaning the bed surface. Another common issue is extruder problems, such as under-extrusion or over-extrusion, which can be addressed by calibrating the E-steps in the firmware and checking the extruder’s performance. If the temperature readings are inaccurate, check the thermistor settings in the firmware and ensure the thermistor is properly connected. If you’re experiencing unusual noises or movements, make sure the belts are properly tensioned and that the motors are correctly configured. Troubleshooting involves a process of elimination to find the cause and solution.
