Reset Factory Settings — K2 Plus¶
A factory reset wipes all user data and returns the printer to its out-of-box state. Use this before installing a new firmware version or when troubleshooting persistent issues.
This is irreversible
A factory reset permanently deletes all data under /mnt/UDISK/. Back up your Klipper config files first.
Reinstall required after reset
After a factory reset, root access must be re-enabled and all Helper Script features must be reinstalled from scratch.
Method 1 — SSH Command (Recommended)¶
Connect via SSH and run:
The printer restarts automatically with all settings reset.
Reconnect to your WiFi network from Settings → Network after restarting.
Method 2 — SSH with Helper Script¶
Note
Only available if the Helper Script is already installed.
This preserves user preferences and network settings while resetting printer configuration.
Method 3 — USB Drive¶
Useful if the printer is not connected to the network or SSH is not available.
- Format a USB drive as FAT32.
- Create an empty file named
factory_reset(no extension) at the root of the drive. - Plug the USB drive into the front USB port while the printer is on.
- The factory reset executes at the next startup.
