4. Setup the X, Y, Z axis offset.

If the distance between the extruder and the platform is too close when printing, then reduce the Z-axis offset value, otherwise, increase it. Normally, we don't need to change the value of X probe offset from exand Y probe offset from extruder.

5. Set 3 (grid points) as bed leveling method

6. Set leveling range as follows

7. Run 3D Touch on Kingroon KP3S: 3D TOUCH 1

Adjust the Z-offset Value

Now everything is ready to start adjusting the Z-offset value of your Kingroon KP3S. You need to adjust the Z-offset on the above .txt file as well. 

Adjust the Z probe offset from extruder value down a little at a time to avoid your nozzle crashes into the heatbed and leads to any damages.  

In this firmware version, you could only adjust Z-offset value through the .txt file in the firmware. Do not support Z-offset adjusting on control screen.

You say that you suggest using the 3D touch using Marlin firmware. Are the steps the same?

Have you completed the tutorial on using the GD32 F303 firmware with modified robin_nano_cfg.txt to get the bltouch working?

I have followed your directions to the letter, installing the firmware update you linked to and setting the offset as specified in the Thingaverse probe bracket link. After the firmware flash, selecting “Autolevel” simply moves the Z axis down until the bumper makes contact with the switch, at which point it stops and does nothing else. Pressing autolevel again raises the Z axis slightly before repeating this process.
