Reasons, Diagnoses, and Solutions

1. Inadequate Infill Leads to Model Surface Collapse

Diagnosis: Preview the model G-code and check if the collapse position is suspended.
Solution: Increase the printing temperature, increase the infill density, or replace the infill pattern.

2. Printing Process Interruption Causes Spots or Scars on the Surface of the Model

A. Power Cut Off During Printing Process
- Diagnosis: Check if the power was cut off during the model printing process and manually clicked to continue.
- Solution: Cut the scar or reprint the model.
B. Midway Pause
- Diagnosis: Check if the printing was paused during the model printing process and manually clicked to continue. If the nozzle stays in the upper left corner of the printing platform, filament leakage due to gravity may form spots on the model when continuing to print.
- Solution: Remove the leaked part of the filament and continue printing.
C. Break Detection Alarm
- Diagnosis: Check if there was a material break alarm during the model printing process, load the filament, and manually click to continue. If the nozzle stays in the upper left corner of the printing platform, filament leakage due to gravity may form spots on the model when continuing to print.
- Solution: Remove the leaked part of the filament and continue printing.

3. Top Corner Bump (Caused by Slicing Algorithm, Temporarily Unsolvable)
