  4. Bowden tube connection: Examine the connection between the Bowden tube and Bowden drive. Loose or ill-fitted connections can cause filament jams. Make sure the tube is tightly secured and properly seated in the drive.

  5. Temperature settings: Improper temperature settings can lead to extrusion proble...
