¶ 1. Phenomenon Description
1.1 Pop-up error for leveling failure
1.2 Build plate scratched by the nozzle
1.3 Error occurred after only detecting a few points during the 16-point leveling process
1.4 The nozzle keeps height-adjusting at the lower left corner, after repeating five times it returns to zero without proceeding with the 16-point leveling, Error Occurrence.
¶ 2. Cause Analysis
2.1 Fault phenomena 1.2 , 1.4 can be determined as height offset issues. In this case, you can check the Z-axis compensation value. If values like -0.04, 0, -10 are observed(Exaggerated values, normal compensation values range between -1 and -3, some may slightly exceed)， it can be determined that the height calibration has failed.
