Probe function not working after final adjustments

Hello, 

During the initial setup and test adjustments I performed before the final assembly, the probe function was working correctly. Since I completed the final adjustments, particularly the connection and calibration of the encoders, the probe no longer works. Instead of moving down, it moves up until it reaches the home position.

My Z-axis has a large travel range, which is why I set a HOME_OFFSET of 100mm to position the torch closer to the table. Manual jogging is in the correct direction, and homing also works properly.

All the travel parameters were the same as those in the attached file when it was working, only INPUT_SCALE and OUTPUT_SCALE have changed.

Do you have any idea what could be causing this issue?

 

Quick update:

If I do a probe test when X and Y are at home the probe test works. But if I move away the Y axe from home, the torch lift up when I do a probe test...

I spend many time on this subject, if someone have an idea...

Thanks
