Problem with 3d touch and bed leveling

[Aeisens]

Hello there,

I have recently bought a 3d touch sensor for my A10. I have installed the sensor successfully, but the auto bed levelling doesn´t work as expected. The 3d touch measures all points on the plate, but when I print on one side the nozzle seems too high and on the other side it is definitely too low (see attached picture). Has anyone a solution for this problem? Could it be that the firmware has the wrong axis orientation that the leveling grid is 180 degree wrong?

thank you in advance for your help

You can refer to these:
1.Check your z offset is correct or not
2.Check the 3dtouch deviation with the gcode(You can test it 3 times then you can get the result)
The deviation should <0.1mm

thank you for your answer, but how do I check the deviation and which gcode do I have to use?

You can try to use the G28 Z0 and G28 Z15
Then test them several times.
