Just started printing on my Spark x I7 and it’s a great upgrade from my Ender 3! However, some of my filament has snapped inside the CFS Lite system, nothing is in the PTFE tubes or sticking out the feeder hole. When I look through the top I can see the stuck piece so I suspect that it’s in the buffer piece.
If anyone has had this problem or knows how to fix it, please let me know. Thanks.
Hello. It would be much clearer and easier to understand if you could include a photo when describing the issue. If a piece of filament is stuck in the CFS Mini drive, press the PTFE tube retainer to remove the tube, then press the button on the front of the CFS unit—this will release the tension on the roller, allowing you to pull out the piece of filament. If a piece is stuck in the print head drive, press the PTFE tube retainer to remove the tube, move the print head all the way to the left (which will trim the filament), press the release lever to loosen the pressure roller, and pull out the filament. Alternatively, you can heat the hotend to 250°C, press the release lever on the print head, and then pull out the piece of filament.
