Welcome to the installation page for Creality Ender 3 V3 KE with KCM Set. This guide provides step-by-step instructions for updating your printer’s firmware to be compatible with KCMSet, downloading STL files for mechanical setup, completing the mechanical assembly, and configuring Klipper settings..
¶ 1) Mechanical Setup of KCM Set on Creality Ender 3 V3 KE
Before starting the KCM Set installation on your Creality Ender 3 V3 KE, you need to 3D print some parts for the ChromaHead and CX-I Extruder assembly.

After completing the mechanical installation, an error message may appear on the printer’s display. This is expected behavior and does not indicate a malfunction.
If the printer's IP address is already known, you can proceed directly to the software configuration phase.
If the IP address is unknown, ensure that an Ethernet cable is properly connected to the printer. On the error screen, press the "Back" button to retrieve the printer’s IP address.
Once the IP address has been obtained, you may continue with the following software setup steps.
Before performing these steps, make sure to back up your configuration files.
Open cmd (Command Prompt) or Putty on your computer.
Enable root access and establish SSH connection to the printer.
Connect via cmd using the IP address. Username: root, Password: Creality2023
Put # at the beginning of the copy_config line, save and exit with esc :wq.
Restart the service.
/etc/init.d/S55klipper_service restart
¶ 3) Editing Configuration Files and Setting Up Serial Paths
After successfully completing the Software-side Setup, the next step is to edit the configuration files and set up the serial paths for the ChromaHead and KCM module included in the KCM Set.
Do not plug in the power cable to the KCM module while the KCM and ChromaHead cables are disconnected!
Also, do not disconnect the KCM or ChromaHead cables while the power is connected!
For a more stable and reliable setup, first connect the KCM module to the printer using a Type-C to USB cable.
Next, connect the ChromaHead cable to the KCM module as well.
While the KCM module is connected to the printer via USB and the ChromaHead cable is properly connected between the KCM and the ChromaHead, plug in the power cable to the KCM module.
From the Mainsail interface, click on "MACHINE" and then open the kcm.cfg file from the config files section.
Click the "DEVICES" button to identify the serial path of the KCM. Copy the correct path and paste it into the "serial:" field. Then, click "SAVE & RESTART" and exit the file.
Click on the "chroma_head.cfg" file. Then click the "DEVICES" button to identify the ChromaHead’s serial path. Copy the correct serial path and paste it into the "serial:" field. After that, click "SAVE & RESTART" and exit the file.
Once the system is powered on, check the "Extruder" temperature. If it displays a value over 100°C, it means the serial paths have been entered incorrectly.
⚠️ Two different serial paths must appear for the ChromaHead and the KCM. Make sure they are not the same — otherwise, the system will fail to start.
Paste the newly identified serial path into the serial: field inside the chroma_head.cfg file.Then click "SAVE & RESTART" and exit the file.
After completing the installation, you also need to configure OrcaSlicer. We recommend downloading the latest version of OrcaSlicer for optimal compatibility. You can use the link below to get the most recent release.
