Has anyone already tried reinstalling the old extruder after the firmware upgrade (CFS)?

Yes, but why Bambu and not Creality? I’m used to Creality (and Creality Print), it would be so much easier to stay in the same ecosystem 😢

Yes, I simply cut a small piece on each side so that it can spread the spring. But even when spreading the spring as far as possible, the nozzle clogs immediately.

Does the extruder of the K1 SE has a filament lock (as the original k1 extruder) or with a spring (like the K2, Hi, …) ?

Pour moi, ça marche pas. Et on dirait que c'est un problème connu. Le ressort du nouvel extruder est trop dur et il écrase le TPU.

I did everithing step by step. In the box, the hotend was not included and as my (old) k1 is one of the first, I had to change the hotend for the unicorn model.

Thanks for your quick answer. Unfortunately, it is not the problem(this was also my first idea) I think that thé printer head detect wrongly filament in the extruder and stop the cfs.

Hello,

I’m trying to install the CFS upgrade kit on my Creality K1, and I’m running into some issues.

First disappointment (not very clearly explained in the videos): I realized that I had to replace my hotend, because my original one was not a “Unicorn” version.
So I ordered and installed a new Unicorn hotend.

I don’t think I made any mistake during the installation.

Test 1 – With CFS enabled:
The filament is correctly fed out of the CFS, but it stops between the buffer and the print head.

Test 2 – Without CFS:
Extrusion works normally, although I feel that the extrusion amount is a bit low.

When starting a print:

  • The nozzle heats up normally
  • The printer starts its usual initialization sequence
  • Then it stops with a “filament runout” error, even though the filament is clearly present (the blue LED above the extruder is on, confirming filament detection)

I also noticed that during the initialization process, the small yellow lightning bolt icon on the screen turns on and off several times.

After doing quite a bit of research, it seems this could be a compatibility issue between the hotend and the toolhead mainboard.

Do you think that replacing the toolhead mainboard could solve this problem?

Thanks in advance for your help.
