Step-by-Step Tevo Tarantula Nozzle Replacement Guide
Replacing your Tevo Tarantula nozzle is a straightforward process, and here’s a detailed guide. Safety first: always turn off and unplug your printer before beginning any maintenance. Ensure the printer is cool to avoid burns.
Gathering Your Tools and Materials

Before you start, gather your required tools and materials. You’ll need the new nozzle, a wrench or socket appropriate for the nozzle size (typically 6mm or 7mm), and a pair of pliers. It’s also helpful to have a small brush to clean the hot end and a heat-resistant glove or cloth to protect your hands. Make sure you have a safe, well-lit workspace. Having the right tools makes the job easier and safer.
Preheating Your 3D Printer
Preheat your 3D printer to the appropriate temperature for the filament you were last using, or to the temperature recommended for PLA or ABS. This softens any filament in the hot end, making the removal of the old nozzle easier and safer. Be careful when working with a hot printer. Always handle the hot end with care.
Removing the Old Nozzle
Use a wrench or socket to carefully loosen and remove the old nozzle. Be mindful of the hot end’s heat, and use a heat-resistant glove or cloth if necessary. Hold the hot end steady with pliers to prevent it from turning. Once the nozzle is loose, unscrew it completely. Be careful not to damage the heating block or any other components. If the nozzle is stuck, apply more heat and try again.
Installing the New Nozzle

Carefully screw in the new nozzle, ensuring it seats correctly within the heating block. Tighten the nozzle with the wrench, but be careful not to overtighten it, as this can damage the threads. Ensure that the nozzle is firmly seated and sealed against the heating block to prevent filament leaks. Tighten the nozzle securely, but do not overdo it to avoid damaging the threads.
Tightening the Nozzle
Once the nozzle is hand-tight, use the wrench to give it a final, firm tightening. Tighten it against the hot end block. This ensures a tight seal and prevents filament from leaking. Refer to your nozzle manufacturer’s instructions for specific torque recommendations to prevent leaks and ensure optimal performance.
Calibrating Your Printer After Nozzle Replacement
After replacing the nozzle, you’ll need to recalibrate your printer to ensure the best possible results. Recalibration will correct for any variations in nozzle dimensions or positioning, leading to more accurate and reliable prints. Take the time to recalibrate after a nozzle change to ensure everything runs smoothly.
Leveling the Bed

Leveling the bed is a crucial first step. Use the printer’s leveling procedure or manually level the bed using the leveling screws. Ensure the distance between the nozzle and the bed is consistent across the entire printing surface. Proper bed leveling ensures that the first layer of your print adheres correctly. Precise leveling helps to avoid issues with bed adhesion.
Adjusting Z-Offset
The Z-offset determines the distance between the nozzle and the print bed at the starting point. Adjust the Z-offset to achieve the correct first layer height. The first layer should be slightly squished onto the bed for optimal adhesion. You might need to adjust the Z-offset in your printer’s settings until you achieve the perfect first layer. A properly calibrated Z-offset makes or breaks the first layer and ensures a successful print.
Testing the Print
After bed leveling and adjusting the Z-offset, print a test object, such as a small square or a calibration cube. Examine the first layer for any issues. Make small adjustments to the bed leveling or Z-offset if needed until you achieve a perfect first layer. Careful testing ensures that your prints are well-calibrated, precise, and aesthetically pleasing. Take the time to test your settings thoroughly.
Troubleshooting Common Issues

Even after a nozzle replacement, you might encounter some common issues. Knowing how to troubleshoot these problems will help you achieve successful prints.
Nozzle Clogging
Nozzle clogs are a common issue, especially with certain filaments or if the printer isn’t properly maintained. Signs of a clog include under-extrusion, inconsistent filament flow, or the filament failing to extrude at all. To fix a clog, try the following: Increase the nozzle temperature slightly, use a nozzle cleaning needle to clear the clog, or perform a cold pull by heating the nozzle, manually extruding filament, and then cooling and pulling it out. Prevention is key: use a filament filter to keep debris out, ensure your filament is stored properly, and regularly clean your nozzle. If a clog persists, you may need to remove and clean the nozzle thoroughly or replace it.
Poor Bed Adhesion
Poor bed adhesion results in prints detaching from the bed during printing. To fix this, ensure your bed is clean, level, and the correct Z-offset is set. Applying an adhesive, such as glue stick or painter’s tape, can help the filament stick to the bed. Adjust your first layer height and print temperature to improve adhesion. Using a brim or raft in your slicer settings can also help with bed adhesion. Proper bed preparation will prevent prints from lifting.
Under-Extrusion

Under-extrusion occurs when the printer isn’t extruding enough filament. The layer lines may appear inconsistent, or the print may have gaps. Causes of under-extrusion include a clogged nozzle, incorrect temperature settings, or the extruder motor not pushing enough filament. Check for clogs, ensure your nozzle temperature is correct for the filament type, and calibrate your extruder. Verify that the filament is feeding correctly. Addressing under-extrusion results in stronger, more accurate prints.
