Load filament fine using spool holder. 'Extruder is clogged' using cfs

I got my filament and machine (k2 & cfs) from creality three weeks ago. The fist few prints were great running off the spool holder using the filamentthat came with the printer until the 4 color set came in. I was able to load all four pla colors into the cfs and ran the multi-color benchy that was in the system already.

I have not been able to load any other filament since that first multi-color print. Every time it tries to load, it flushes out the old just fine and then it won’t move any more. The cfs locks up and doesn’t help push more through. This happens on all four slots. I have tried moving them to different spots, pulling out what’s in there and clipping off anything with motor marks on it and reinserting,

The machine just keeps saying the extruder is clogged even tho it flushes out the old filament just fine then it’ll say it’s having retracting problems while retracting just fine.

Everything works great when using spool holder. I can swap out different filaments with no problem.

I had the same problem and it was the filament sensor at the top of the extruder. The blue led stayed on even with filament loaded or unloaded.

It only happens when using cfs. It works perfectly using spool holder

maybe your cfs unit has a jam or the buffer unit? or not retracting properly because cutter isnt working well?

I’ll check the buffer and the motors in the cfs but the cutter works fine. I can swap out whatever filament I want using the spool holder, it just won’t work right with the cfs

something doesnt seem right, if its only 3 weeks old. contact creality for warranty info.

こんにちは。
・スプールホルダーとCFSを併用しているのですね。
・電源を入れた時CFSのフィラメントは押出し引き戻しが行われている。
4本のうち1本でもバッファーを通過してますか?
問題なくLEDライトが点灯する。
・CFSでプリントする時
CFSのフィラメント情報が正しく読み取られていますか?
印刷開始前に「Enable CFS」のチェックは入っていますか?
・一度、スプールホルダーを外してCFSだけにしてプリント確認する。
このぐらいの事しか思いつきません。

I only use the spool holder or I use the cfs, not both.

When i use the spool holder, I disconnect the cfs and vice versa.

The LEDs all light up when they are suppose to.

The only thing I can think of is that the motors in the cfs don’t feed more filament into the machine when it’s trying to flush the old filament. They’re locked up while the Extruder is trying to pull more into it. Is this a buffer issue or is this a cfs issue?

Can I bypass the buffer some way? I only have one cfs so I don’t think it’s absolutely necessary.

こんにちは。
単体で使用しているんですね。
CFSの問題かもしれませんね?。
サポートと連絡を取り合った方が良いと思います。
時間はかかりますがちゃんとサポートしてくれます。

They told me they’re creating a ticket for the issue but it’s been 5 days and haven’t heard anything. The warranty runs out in a week

こんにちは。
時間が掛かります。たくさんのエラーが来ているんだと思います。
ヒューマンチャットサポートをお勧めします。
自分の番が来るまで時間が掛かりますが、確実につながります。
待っている間に注文書やプリンター・CFSのシリアルナンバーを準備すると良いです。
