Affected Models
Applies to all models
A1A1 MiniP1PP1SX1 CarbonX1E
Likely Causes
  1. Partial clog in the nozzle from carbonized filament residue
  2. Heat creep causing filament to soften too early in the cold zone
  3. Incorrect temperature for the filament type resulting in under-extrusion
  4. Worn nozzle with an enlarged orifice causing inconsistent flow detection
How to Fix It
1
Pause the print and perform a filament unload/reload cycle from the touchscreen
2
Try a cold pull: heat to 250C, insert cleaning filament, cool to 90C, then pull firmly to extract debris
3
Replace the nozzle with a fresh Bambu Lab hardened steel or stainless steel nozzle
4
Verify the hotend fan is running at full speed to prevent heat creep
5
Check that the correct temperature profile is set for the filament being used
Pro Tip
This fix requires some technical knowledge. If you're unsure about any step, consider contacting support or a qualified technician.
