Not Extruding At The Start Of The Print

If you encounter a situation where your 3D printer is not extruding filament at the beginning of a print, there are a few potential causes to consider. Firstly, it could be due to incorrect extruder calibration, which can disrupt the proper flow of filament. Additionally, a clogged extruder or nozzle may prevent the filament from extruding smoothly.

To address this issue, you can try priming the extruder before starting the print. This involves manually extruding a small amount of filament to ensure a consistent flow. Another solution is to adjust the nozzle height. If the nozzle is too close or too far from the print bed, it can affect the extrusion process. By achieving the optimal nozzle height, you can improve the filament flow.

Remember that clearing any clogs or blockages in the extruder or nozzle may also be necessary. Make sure to follow the manufacturer's guidelines or consult the printer's manual for instructions on how to unclog the extruder effectively.

Addressing the issue of not extruding at the start of a print is crucial for preventing print failures and achieving successful 3D prints. By implementing these troubleshooting steps, you can optimize the extrusion process and enhance the overall print quality.

If you're experiencing issues with your 3D prints not sticking to the bed, there are several factors that could be affecting bed adhesion. It's a common problem that can lead to failed prints and frustration. Fortunately, there are solutions to help you overcome this issue and ensure successful prints.

Here are some troubleshooting tips to improve bed adhesion:

1. Bed Leveling: A level bed is crucial for proper bed adhesion. Use a level or a calibration tool to ensure that the bed is perfectly leveled. Adjust the bed leveling screws or knobs as needed to achieve an even and stable surface.
2. Adjust Nozzle Height: Incorrect nozzle height can result in poor adhesion. Make sure the nozzle is positioned at the correct distance from the bed. You can adjust the nozzle height manually or use the bed leveling feature of your 3D printer to fine-tune the nozzle height.
3. Change Bed Surface: Different bed surfaces can provide varying levels of adhesion. If you're having trouble with adhesion, consider changing the bed surface. Popular options include glass beds, build plates with adhesive surfaces, or specialized printing mats.
4. Use Adhesives: In some cases, using adhesives can greatly improve bed adhesion. Applying a thin layer of glue stick, hairspray, or ABS slurry (a mixture of ABS filament and acetone) to the bed surface can help prints stick better.
5. Adjust Bed Temperature: Bed temperature can also impact bed adhesion. Depending on the filament you're using, adjusting the bed temperature may help improve adhesion. Experiment with different bed temperatures within the recommended range for your filament type.

By following these troubleshooting steps, you can enhance the bed adhesion of your 3D prints and ensure successful output. Remember to regularly check and adjust bed leveling, nozzle height, and bed temperature to optimize adhesion. Additionally, don't hesitate to experiment with different bed surfaces and adhesives to find the combination that works best for your specific printing needs.

Jammed Nozzle / Clogged Extruder

If you encounter a jammed nozzle or clogged extruder while 3D printing, it can disrupt the filament flow, resulting in printing issues. These problems are often caused by heat creep, where excessive heat travels up into the cold end of the extruder, or particles blocking the nozzle.

The good news is that there are several solutions you can try to resolve this problem and get your printer up and running smoothly again:

1. Manually push the filament: Gently apply pressure to manually feed the filament through the extruder. This can help dislodge any blockages and restore the proper flow.
2. Reload filament: If pushing the filament manually doesn't work, try unloading and reloading the filament. This can help clear any obstructions and ensure a clean pathway for filament feeding.
3. Clear the nozzle: Use a small-diameter needle or a nozzle cleaning tool to clear any debris or blockages from the nozzle. Be careful not to damage the nozzle while performing this task.
4. Cold pull: Another effective method for clearing a clogged nozzle is to perform a cold pull, also known as a "cold end" or "atomic" pull. This involves heating the nozzle, then quickly cooling it down while pulling out the filament. The sudden temperature change can help dislodge any stuck particles and clear the nozzle.

“A jammed nozzle or clogged extruder can be frustrating, but with a little troubleshooting and patience, you can quickly get back to 3D printing without any issues.”

Pillowing and Smashed First Layer

Pillowing, characterized by incomplete top layer fills and gaps, can significantly impact the quality of your print's surface. Additionally, a related issue known as a smashed first layer, often referred to as an elephant's foot or bulging first layer, can pose challenges. These problems can arise due to a range of factors, including improper cooling, incorrect bed leveling, and incorrect first layer height or extrusion rate.

To address these issues, consider the following solutions:

1. Adjust the cooling settings: Proper cooling is essential to ensure the top layers of your print solidify correctly and reduce the likelihood of pillowing. Experiment with adjusting the fan speed or cooling settings in your slicer software to find the optimal cooling strategy for your specific 3D printer.
2. Level the bed: An uneven or warped bed can contribute to unwanted bulging in the first layer. Take the time to carefully level your bed, ensuring it is even across all corners and the center. This will help create a solid foundation for your print.
3. Adjust the first layer height: If your first layer is too close to the bed, it can result in excessive squishing and bulging. Conversely, if the first layer is too far from the bed, it may not adhere properly. Make sure to fine-tune the first layer height to achieve the optimal balance.
4. Adjust the first layer extrusion rate: If the extrusion rate for the first layer is too high or too low, it can contribute to inconsistencies in the print. Experiment with adjusting the extrusion rate to ensure a smooth and evenly extruded first layer.

By implementing these solutions, you can overcome pillowing and smashed first layer issues, resulting in improved print quality and surface finish.

Expert Tip:

Consider adding a brim or raft to your print settings. These features create a wider base for your print, improving bed adhesion and minimizing the impact of pillowing and smashed first layer issues.
