If the heating cartridge wire is burnt on the edge, it is recommended to replace it for safety reasons. A damaged heating cartridge wire can affect the temperature control of your 3D printer.

For the Capricorn PTFE tube, if it is visibly damaged or deformed, it is advisable to replace it. A damaged PTFE tube can cause issues with filament feeding and extrusion.

Regarding the extruding gear with black marks inside the wheels, this might indicate filament residue or wear. If it is affecting the extrusion process, you may want to consider replacing it. However, if the gear is still functioning properly and there are no other issues, it may still be usable.

Remember, it's always a good practice to regularly inspect and maintain your 3D printer components to ensure optimal performance and longevity. If you have any doubts or concerns, it's best to consult the manufacturer or an experienced technician for further guidance.
