Root Guide

Rooting Steps

Please refer to https://github.com/CrealityOfficial/K1_Series_Annex.

1. Enter “Settings - Root Account Infomation”, and accept the “Warning”, then you can get the root account and password of your printer.
2. If the “Warning” is not accepted, you are not allowed to use the SSH to log into the root account.

Rooting Risks

Please read the “Root Disclaimer and Risk Warning” carefully before you try to get the root account and password.

1. Enabling services like Moonraker may occasionally lead to excessive memory usage and system crashes.
2. For a rooted device, its hardware still enjoys after-sales services within the warranty period, but no technical support will be provided to the root-related software.
3. In case the firmware fails after rooting, you can roll back the firmware. For K1 Max, the earliest firmware you can roll back to is V1.3.1.19. For K1, the earliest firmware you can roll back to is V1.3.1.28.

Known Issues

1. Updating the firmware from V1.3.0.x will disconnect the printer from Creality Cloud. To reconnect, please bind them again.
2. The system may freeze if you try to upload a file when the 8G storage space is already filled up. In this case, you need to flash the firmware via a USB cable. To avoid this risk, please delete useless G-code files regularly.
