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.

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

Víctor You can change its direction by modifying the text file within the firmware package. If you have no idea about it. Please send an email with a screenshot of this comment to supportkingroon.com, our guy will show you how.

@sang bok park Not yet. We just update the firmware for 303 and 103, adding the Z Offset Wizard. We will go for it next. Once we finished the 3D touch firmware for 407, we will publish it with our latest video on YouTube and in our Facebook group.

@Mishel It is not currently. We will make it available soon.

sang bok park - April 11, 2022

Is there no kingroon kp3s 3.0 bltouch stm32 f407 firmware?

@Misael
Which mainboard does your printer use?

Kingroon 3D Official - February 22, 2022

@Lukas
The 303 and 103 mainboards are used the same firmware, you could install the 3D-touch according to this tutorial directly.
