7. Solutions for Glue Leakage and Overflow 1. Phenomenon description

During the printing process of the machine, the filament overflows near the nozzle/the filament covers the nozzle.

2. Cause analysis

During the printing process, the first layer of the model did not stick to the platform and was carried away by the nozzle, causing the nozzle outlet to be blocked and the filament to cover the nozzle.

Non-stick platform problem solutions pls back to First Layer Adhesion Issues/Model not Sticking to Build Plate/Nozzle Scraping Infill.

3. Troubleshooting and solution

3.1 Check whether the nozzle heating function is normal.

If normal, heat the nozzle to 300°. Clean the filament near the nozzle fan cover, refer to the video on replacing the nozzle kit, and remove the fan cover. (Note here that the fan cable is unplugged after the power is disconnected) Reheat to 300° and clean the spill near the nozzle. (Note: Some areas cannot be melted by heating, you can use a heat gun/hair dryer to assist with heating.) Replace damaged parts, such as fan covers, air guides, etc., and reinstall them. 3.2 If the heating function is abnormal, unable to heat.

Check whether the fan cover can be disassembled. If the fan cannot be disassembled due to overflow, you need to use a heat gun/hair dryer to clean the filament. Since it cannot be heated, you need to remove the nozzle kit with the heat sink block. (Just loosen the 2 screws selected in the picture below) Replace damaged parts, such as nozzle kits, fan shrouds, air guides, etc., and reinstall them. 8. Solution to the Problem of Abnormal Fan Noise/Auxiliary Cooling Fan not Rotating Ender-3 V3 has four fans.

Throat Fan: Located on the left side of the heat sink block of the nozzle kit, its function is to cool the throat; The fan will work after heating the nozzle.

Mainboard Fan: Located at the bottom shell of the machine, its function is to cool the mainboard; The fan will operate as soon as printing starts, if not in printing status, it will only turn when the motherboard chip exceeds 45 degrees.

Model (Nozzle) Cooling Fan: Located within the fan shroud, its function is to cool the extruded filament at the nozzle, allowing the model to solidify and stabilize more quickly; This fan typically activates during the printing of the second layer (based on G-code parameter settings), or can be manually controlled via the screen settings.

Auxiliary Cooling Fan: Located behind the nozzle, it functions to cool specific areas of the model, such as overhangs and bridging areas; This fan is off by default and will only be turned on for specific areas of the model. (Slicing software for 3D Print) Can be manually set via the screen.

Through the information, you can confirm the position of the abnormal noise fan through the fan position and working mode, and then troubleshoot based on the cause of the abnormal noise.

1. Cause analysis

1.1 Filament interference.

1.2 Material residue interference.

1.3 Fan blade damage.

1.4 Fan anomaly.

2. Troubleshooting and solution

2.1 After confirming the position of the fan, it can be removed independently for testing to check for any abnormal noise; if there is none, it means there is interference in the fan assembly.

2.2 Check whether the fan blades are damaged or if there is residue from filament.

2.3 Replace the fan.

9. Nozzle Does not Discharge Filament 1. Phenomenon description

The nozzle does not discharge filament when printing starts.
