¶ When it happens?
The error occurs during the leveling process.
¶ Passible causes
- The printer is leveled on the unstable ground
- The surface of the heated bed is tilted
- The leveling sensor cables is loose
- The leveling sensor circut board is damaged
¶ Troubleshooting steps
¶ Tools needed
- 2.0 mm Allen key
- 2.5 mm Allen key
¶ Step 1 Place the printer on a smooth ground and level it again
- Place the printer on a smooth surface.
Note: The printer should be placed in a relatively stable position when leveling. Otherwise it will affect the leveling and collect data, and the data will be error if it is abnormal many times.
- After turning on the printer, perform the leveling operation to observe whether there is an error message.
¶ Step 2 Adjust the balance of the heated bed
If there is still any abnormality, adjust the balance of the heated bed following the steps below.
- Observe the heated bed and the height of the top of the Z-axis screw is different after homing process.
If the heated bed is significantly tilted and the height of the top of the Z-axis screw is different, adjust it according to this tutorial.

- After adjusting the balance of the hot bed, perform the leveling operation again and observe whether there is any abnormality.
¶ Step 3 Re-plug the leveing sensor cables and check the pins in the terminals.
There are 4 leveling sensors installed at the 4 corners of the printer heated bed. When an error message appears, if the nozzle stops in the position that is obviously close to a certain corner, it is considered that the leveling sensor of that corner is abnormal.
- Power off the printer, disassemble the heated bed assembly.

- Re-plug the leveling sensor cable, and check the pins in the terminals.
Note: The picture below shows the normal situation of the pins.
¶ Step 4 Swap the leveling sensor cables and plug in
- Replace the leveling sensor with the other sensor on the same side.
The 4 leveling sensor corner mounting positions correspond to the location of their cable insertion ports. According to Step 3, you can find the abnormality of the leveling sensor in one of the corners.
2. Operate automatic leveling and observe the nozzle.
After interchanging the leveling sensor cables, install the regeneration bed assembly. Operate atomatic leveling on the touchscreen and observe where the nozzle stops when the error message appears.
If the nozzle remains in the same position when an abnormal error is reported, it indicates that the "leveling sensor circuit board" is faulty. Replace the leveling sensor circuit board with a new one.

If the nozzle dwell position changes and becomes an adjacent corner on the same side when an abnormal error is reported, it indicates that the "leveling sensor" is faulty, and please replace it with a new leveling sensor.
