Cause of Failure:

When leveling an exception, the AnkerMake App will display a pop-up window as shown in the figure below. There are several possible reasons:

1. Z-axis motor abnormality (motor itself, motor wire looseness, Marlin drive).
2. Marlin data transmission timeout.
3. Point data is abnormal.
4. The strain gauge sensor signal line is loose.
