Important Notice Before Use
Please update the printer firmware (Creality OS) using the included USB drive before first use; subsequent updates can be done via OTA. When the CFS system is connected, the maximum print size will adjust: K1, K1C, and K1 SE to 220 × 215 × 250 mm, and K1 Max to 300 × 295 × 300 mm
Using the stock spool holder will retain the original print size.
Compatibility Reminder
The K1 Series Multi-Color Upgrade Kit (with integrated cutter extruder) is only compatible with K1 printers using an integrated hotend.
K1 Max units shipped before January 2024 use a split-style hotend.
K1 units shipped before February 2024 also use a split-style hotend.
For these models, please purchase the Unicorn Integrated Hotend Kit (Part No. 4001030132) separately before using the upgrade kit.
Be sure to indicate this information on your product page to avoid customer issues.
FAQs
- Is this upgrade kit compatible with all K1 series printers?
→ Only with K1 series printers that use the integrated hotend. For older models with split hotends (K1 Max before Jan 2024, K1 before Feb 2024), you must purchase the Unicorn Integrated Hotend Kit (Part No. 4001030132) separately. - How do I check if my K1 printer uses a split hotend?
→ Check the production date:
- K1 Max units shipped before January 2024
- K1 units shipped before February 2024
These typically use split hotends.*
- What is the benefit of the new extruder?
→ It features a built-in cutter and filament run-out sensor, allowing accurate filament switching and saving filament waste. The cutter is durable and easy to maintain. - Do I need to update the firmware after installation?
→ Yes. Use the included USB drive to update the firmware (Creality OS) for the first time. Later updates can be done via OTA. - Will my print size change after installing the CFS system?
→ Yes, when using CFS, the print size changes:
- K1 / K1C / K1 SE: 220 × 215 × 250 mm
- K1 Max: 300 × 295 × 300 mm
If using the stock spool holder, the original build volume remains unchanged.
- Does this kit support automatic filament switching and detection?
→ Yes. It supports automatic filament detection, switching, and RFID-based filament recognition when connected to CFS.
