3.Confirm that there is a probe self-check.

4.Raise the Z axis a bit to make sure there is enough space.

5.Use your finger to touch  the automatic leveling probe in the process of autoleveling.

If the X axis stop going down on the moment when you touch the probe, then It may be that the auto-leveling device is crooked or the probe is crooked.
