Update 3D Touch Firmware for KP3S
Configure the Z-offset Value
To configure the Z-offset value of Kingroon KP3S. Open the .txt file in the firmware files you downloaded from the above link.
1. Change the mode as” cfg_leveling_mode” 1
2. Setup endstop into Z Min_Probe_endstop_inverting 0 # Z probe
3. Set the leveling probe on Zmax: Z_min_probe_pin_mode 2
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.
