Preheating the Nozzle
Before changing filament, preheating the nozzle is essential. Preheat your Tevo Tarantula’s nozzle to the recommended temperature for the current filament, typically around 200-220°C for PLA and 230-250°C for ABS. This heating softens the old filament inside the nozzle, making it easier to remove. The preheating process can be initiated via the printer’s control panel or through your slicing software. Ensure that the nozzle reaches the desired temperature before proceeding to the next step. Waiting for the nozzle to heat up properly ensures that the old filament melts sufficiently, facilitating a clean and efficient removal process, and preparing the printer for the new filament.
Removing the Old Filament
Once the nozzle is preheated, you can start removing the old filament. Use the printer’s control panel or slicing software to initiate the filament retraction function. This will pull the filament out of the hot end. If the filament doesn’t retract smoothly, manually assist the process by gently pulling the filament while the extruder motor is retracting. If the filament breaks off inside the hot end, use the needle tool to push the remaining filament out. It is also helpful to gently pull the filament while it’s still soft, to help the filament flow out from the nozzle. This part of the process requires careful attention to prevent damage to the hot end. Make sure the old filament is completely removed before loading the new one.
Loading the New Filament
After removing the old filament, the next step is loading the new one. Cut the end of the new filament at a 45-degree angle to create a clean, sharp tip. Insert the new filament into the extruder, ensuring that it feeds smoothly. Use the printer’s control panel or the slicing software to extrude a small amount of filament until the new color appears at the nozzle. Make sure there are no air bubbles or clogs during this process. This step is crucial to ensure that the new filament is fully loaded into the hot end and ready for printing. Watch carefully as the new filament extrudes to confirm it is flowing correctly, which helps ensure good print quality.
Adjusting Settings for New Filament
After loading the new filament, it’s crucial to adjust your print settings accordingly. Each filament type has different requirements for temperature, bed adhesion, and print speed. Refer to the filament manufacturer’s recommendations to find the ideal settings for the material you are using. Common adjustments include nozzle temperature, bed temperature, and first-layer adhesion settings. Fine-tuning these settings can significantly improve the quality of your prints. It’s advisable to run a test print, such as a calibration cube, to verify that the settings are correct before starting a large print. Make small adjustments and monitor the print quality until you achieve optimal results for your new filament.
Troubleshooting Common Issues
Even with careful preparation, problems can arise during filament changes. Knowing how to troubleshoot these common issues can save you time and frustration. These troubleshooting tips provide practical solutions to resolve the most frequent problems encountered during filament changes. Being able to diagnose and fix these issues quickly can prevent failed prints and maximize your printing efficiency.

Filament Not Feeding Properly
If the filament doesn’t feed properly, it can be due to various reasons. Check that the extruder gear is properly gripping the filament. Make sure the filament isn’t tangled on the spool. Clean the extruder gear from any accumulated filament debris. Increase the nozzle temperature slightly to help the filament melt and flow more easily. If the filament still doesn’t feed, there might be a blockage in the hot end. In that case, use a nozzle cleaning tool to clear the obstruction. If none of these solutions work, inspect the PTFE tube in the hot end for damage or blockages. Make sure that the filament is correctly inserted and that there are no obstructions to its movement.
Nozzle Clogging
Nozzle clogging is a common issue that can halt your printing process. This can occur due to filament degradation, impurities, or improper temperatures. If the nozzle is clogged, first try preheating the nozzle to the filament’s recommended temperature. Then, manually push the filament through or use the retraction function to clear the blockage. Another method is using the needle tool to insert into the nozzle. If the clog persists, consider performing a “cold pull” where you heat the nozzle, manually push filament through, and then cool it down, pulling the filament out to remove the clog. You may also need to disassemble the hot end and clean it thoroughly. Regular maintenance and monitoring of your filament quality can help prevent clogs.
Bed Adhesion Problems
Poor bed adhesion can cause prints to fail early in the process. Ensure the print bed is level and clean before starting a print. Applying a thin layer of glue stick, hairspray, or blue painter’s tape can improve adhesion, especially for materials like ABS. Adjust your first-layer settings such as the nozzle height and initial print speed to optimize bed adhesion. Also, ensure that the bed temperature is correct for the filament you are using. For instance, PLA typically benefits from a bed temperature of around 60°C. Regularly clean the print bed and recalibrate the level to prevent adhesion problems. Proper bed adhesion is crucial for ensuring the success of your prints, so these steps are very important.
