K1 Series CFS Upgrade Accessory Kit

Compatible Models: K1/K1 Max/K1C/K1 SE（With Integrated Nozzle）

The CFS Upgrade Kit is not compatible with split-type nozzles. If you wish to upgrade, you will need to purchase an integrated nozzle hotend separately

Tips:

* Please update the firmware (Creality OS) with the included USB drive upon the upgrade. For subsequent updates, you can use the OTA function.
* While using CFS, the print size of K1, K1C and K1 SE changes to 220 × 215 × 250 mm, and the print size for K1 Max changes to 300 × 295 × 300 mm. The print size stays unchanged if you use the stock spool holder.

• Note: When upgrading to multicolor printing, the USB port remains functional but will be occupied during the process. Additionally, the PTFE tube must be fed into the printer vertically, which prevents the top cover from fully closing. Improper alignment may lead to tube friction or feeding issues.
