Creality K2 Plus Automatic Refill: Never Stop Mid-Print Again

There’s nothing more frustrating than running out of filament mid-print. With the Creality K2 Plus and its CFS, this issue is a thing of the past—thanks to the Automatic Refill function.

This guide will show you how it works and how to set it up, ensuring smooth filament changes without interrupting your prints.

What is K2 Plus Automatic Refill? The Automatic Refill feature allows your K2 Plus to automatically switch to a backup filament when the current spool runs out—provided the replacement filament matches the same type and colour.

🎯 For example: If Filament Slot 1 (white PLA) runs out during a print, the system will automatically switch to another white PLA filament in Slot 3, without pausing the print or requiring manual intervention.

This ensures smooth, uninterrupted printing, especially for long or high-infill models.

How to Activate the Automatic Refill Function 1. Access the print screen and enter the multi-color CFS filaments setting interface Place the same filaments into different slots in CFS, and set the filaments to be replenished on the editing page, with the same name and colour.

2. Click the Multicolour Print Settings in the lower left corner

3. Click to start automatic refill (the system will default to select filaments with the same properties and preferentially select filaments with the same colour)

4. Once automatic refill is activated, you can click the Auto button to view the automatic refill sequence

How It Works During Printing Once automatic refill is activated, here's what happens:

If a filament runs out mid-print, the K2 Plus pauses momentarily. The printer automatically switches to another CFS slot containing the same material and colour. Printing resumes automatically—no manual action needed! You don’t have to stop your print, change the spool manually, or worry about failed prints due to filament depletion.

The Automatic Refill feature on the Creality K2 Plus is a game-changer for uninterrupted, multi-hour or overnight prints. Whether you're using the CFS for multi-color prints or just ensuring long print reliability, enabling this feature gives you peace of mind and saves both time and material.
