Here is the cable information of the 3D Touch on our site:

Green line: -, GND

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.

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.

On my mainboard, Z- is not available. Only Z+, so I wired the black and white cable there. I am using the 3DTouch V3.2

My leveling does not work. when switching on, the 3DT blinks red twice and when click autolevel, it moves to point 1, then goes up ad sits there, about 1.5" above the bed. I would assume because of the Z+???? What can I change to correct this in the config file? Thank you in advance!

I’m trying using 3D Touch 3.2 by Geeetech – no success. I tried test probe with:

M280 P0 S120 … continualy test probe down/up … WORKS
M280 P0 S160 … reset (stop continualy test) … WORKS
M280 P0 S10 … probe down … NOT WORKS
M280 P0 S90 … probe up … NOT WORKS

Your firmware for GD32F303 (board v1.3)does not support 3D Touch ? Btw – where can I get stock firmware for this GD32F303 board ? There is missing bed leveling submenu now.

When is pluged Z-stop to Z- terminal, then is not possible controll Z-axis via PC and G-CODE.

On your photos is Black/White pluged once to Z- , once to Z+. What is relevant ?

Flashed fw for BLTouch to KP3S board with GD32F303. When is printer turned on, 3D touch shines red and probe twice goes out and back.
But when I am using ‘Autoleveling’ button , 3D touch only shines red but no movement.

Good day
I have a problem with the product’s functionality.
I have Kingroon KP3s and when I followed this manual, the device does not work.
I connect product: https://www.aliexpress.com/item/32840691571.html?spm=a2g0o.order_list.0.0.10b81802p8Yyhz
When the printer is switched on, it extends and retracts the measuring point twice, moves up and stops. I measured all the cables and everything is fine.
I also tried to exchange the Z + pins for the Z-, and the result was just that my head didn’t stop when I went home.
I do not know where the problem is.
Can you help me? Thank you
