Features and Description

The surface or internal structure of the model appears incomplete, with noticeable gaps, resulting in a honeycomb-like pattern, as shown in the images below:

Reasons and Checks, Solutions

A. External Resistance Leads to Filament Jamming

• Check: Verify if the filament is knotted or excessively bent.
• Solution: Sort out the knotted filament, straighten any bent sections, and reduce the resistance when pulling the filament in.

B. Nozzle Assembly Extrusion Spring Too Tight (or Too Loose)

• Check: Determine if pressing the extrusion clip on the right side is difficult, which can cause wear and tear of the filament due to overly tight extrusion gears.
• Solution: Use the H2.5 hexagonal wrench to adjust the tightness of the extrusion spring as shown below.

Insufficient Printing Temperature

• Check: Verify if the printing temperature is appropriate; increase the temperature when printing larger models. For instance, for PLA + 0.4mm nozzle, print regular-sized models at 205°C and larger models (length or width over 150mm) at 220°C.
• Solution: Adjust the printing temperature as needed in Studio via Filament Settings > Temperature.

Hot End Cavity Affects Filament Extrusion

1. Nozzle Has Foreign Objects
   1. Check: When the nozzle is extruded alone, if the discharge is not smooth, the filament is not uniform, and cannot be extruded vertically, there may be foreign objects in the nozzle.
   2. Solution: Heat the nozzle to 180°C, insert a needle into the nozzle to clear blockage, and then manually extrude until the extrusion is smooth

2. Nozzle Wear
   1. Check: If the printing model shows both material shortage and stringing, it may be due to nozzle wear. Check whether the nozzle outlet is worn or deformed.
   2. Solution: See below for the nozzle replacement guide.

E. Flow Parameter Setting Issues (Simple Mode Not Considered)

• Check: Verify whether the flow parameter in Studio is set to 1 (100%) through Extrusion Multiplier in Filament Setting > Filament.
• Solution: If the problem of insufficient discharge cannot be solved by other methods, gradually increase the flow rate to 1.05 (105%), 1.1 (110%), or 1.15 (115%) to test the printing effect. It is generally not recommended to exceed 115%.

F. Nozzle Diameter and Slice Setting Parameters Do Not Match

• Check: Ensure that the nozzle size selected on the equipment matches the parameters.
• Solution: Use the correct nozzle and matching nozzle parameters.
