Features and description

The surface or internal structure of the model is not continuous and lacks material, making the model appear honeycomb-like, as shown in the figures below.

A. Filament Winding Causing Under-Extrusion

Diagnosis: Check whether the filament is knotted or bent too much.

Solution: Sort out the knotted filament, straighten the bent sections, and reduce resistance when the filament is pulled in.

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

• Diagnosis: Check whether pressing the extrusion clip on the right side of the figure is stiff to avoid wear and tear of consumables caused by too tight extrusion gears.
• Solution: Use an H2.5 hexagonal wrench to adjust the tightness of the left extrusion spring, as shown in the figure below.

1. Insufficient Printing Temperature

• Diagnosis: Check whether the printing temperature is appropriate. Increase the temperature when printing larger models. For example, for PLA with a 0.4mm nozzle, print at 205°C for regular-sized models and at 220°C for large models (length or width more than 150mm).
• Solution: Check and appropriately raise the printing temperature through Filament Settings > Temperature in Studio.

2. The Hot End Cavity Affects the Extrusion of Filament

• A. Nozzle Has Foreign Objects
  • Diagnosis: When manually extruding, check if the discharge is not smooth, the filament is not uniform, and cannot be extruded vertically.
  • Solution: Heat the nozzle to above 180°C, insert a needle into the hole to stir, and then manually extrude until the extrusion is smooth. Refer to the following resources for detailed instructions:
    • Article: How to Replace the Nozzle
    • Video: How to Replace the Nozzle
• B. Nozzle Wear
  • Diagnosis: The printing model shows both material shortage and stringing, which may be due to nozzle wear. Check whether the nozzle outlet is worn or deformed.

Solution: Refer to the link for the nozzle replacement guide

3. Flow Parameter Setting Problem (No Need to Consider When Using Simple Mode)

• Diagnosis: Check whether the flow parameter in Studio is set to 1 (100%) through Extrusion Multiplier in Filament Settings > 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%), 1.15 (115%) to test the printing effect. Generally, it is not recommended to exceed 115%.

Nozzle Diameter and Slice Setting Parameters Do Not Match

• Diagnosis: Check whether the nozzle size selected on the equipment is consistent with the parameters.
• Solution: Use the correct nozzle and corresponding nozzle parameters.
