Easy Plate Swap Creality K1C, K1, K1 Max Nozzle Brush Mod w/ GCode for Fast Nozzle Wipe

UPDATE 29/9/25: I will soon be introducing new code so you can also control the acceleration of the wiping motion. Please be considerate with the values because it will wear out your nozzle brush much quicker. I recommend values 10-12k accel. If you set it to 20K, you'll probably cause a belt skip so do it at your own risk!!!

UPDATE: 19/10/25
NEW CODE ADDED. TEST AT YOUR OWN DISCRETION!!! File is called “k1c acceleration nozzle brush wipe” I am NOT responsible for any damages to your printer so please be considerate with your acceleration values!

DISCLAIMER

==========

I am not responsible for any damages to your machine. If you proceed to do this mod, it will be in your own endeavours and you should be aware of the risks.

For those that print remotely, want to make constant changes on the fly or if an update overwrites the function and you aren't around, you will need root access/SSH to change the config file.

NOTES

======

I own a Creality K1C and recently had to do some maintenance. Since Creality does not sell the nozzle brush separately, I have decided to use the ones for the Bambu A1. There will be two major steps; a nozzle brush holder and modified gcode. I have written a separate wiping function called NOZZLE_BRUSH. Creality's CX_NOZZLE_CLEAR can work, but it will move incredibly slowly. My slicer is Orcaslicer and I will be accessing Klipper through the Fluidd interface. 

This should work for K1 and K1 Max owners as well. I saw this issue online where others wanted the fast brush wiping motion, but it appeared that the forums never got a proper answer.

I am publishing this as a remix and as free so others can have an easier time finding it. If you can improve it, feel free to do so. 

Please print the nozzle brush holder in something temperature resistant. I have printed it in PETG. Do NOT use PLA, it'll melt upon contact with the nozzle. 

============

INSTALLATION

============

1. Make sure the machine is powered off and backup your original gcode_macro.cfg file. 
2. Unscrew the 2 screws at the rear threaded rod. 
3. Adhere the nozzle brush onto the nozzle brush holder.
4. Insert the nozzle brush holder. It should dimensionally align. 
5. Install the screws. 
6. Remove the gcode_macro START_PRINT.
7. Open the modified gcode file. Copy and paste the NOZZLE_BRUSH and the new START_PRINT function. (Ctrl F is your best friend)
8. Save and restart the firmware.
9. Start a print to check if it wipes the nozzle. 

For those that cannot be bothered to check documentation:
