¶ CFS PTFE tube
The PTFE tube is a consumable part that may wear out over time due to friction with the filament. It is recommended to regularly check the wear condition of the PTFE tube during routine maintenance. If the tube is worn and not replaced in time, it may cause abnormal feeding or filament clogging in the CFS. The PTFE tube used in the CFS has a specification of 4*2.5mm.
Under normal usage frequency, it is recommended to replace the PTFE tube every two months to ensure smooth filament feeding and retraction in various scenarios. For abrasive materials like fiber-reinforced filaments, it is advised to inspect monthly and replace the tube promptly when obvious wear is observed.

¶ Filament spool shaft drive kit
If the filament spool shaft drive kit is obviously damaged or not securely installed, causing poor meshing between the gears of the filament intlet assembly and the black gear of the feeding/retracting device, it may lead to feeding failure.

¶ CFS Desiccant
There are two locations for storing desiccant in the CFS, which can ensure long-term filament storage at an appropriate humidity level.
It is recommended to check the status of the desiccant every two weeks. If the desiccant has become ineffective, please replace it promptly. If the desiccant is not replaced for a long time, it will lose its water absorption ability and thus lose its protective capacity for dried filament. Additionally, if not replaced for over 3 months, the desiccant may leak water, causing short circuits or damage to the internal circuits or electronic components of the CFS.
