This prompt indicates that during the Z-axis homing, the sensor may be subjected to external interference, such as vibration or abnormal forces, leading to a Z-axis homing issue.
Eliminate external influences: During the Z-axis homing, do not touch the printer to avoid interference with the sensor.
Check health: Observe if Z-axis operation is affected by other factors, such as mechanical obstruction or abnormal noise.
Z-axis lead screw foreign objects: When printing materials with volatile substances such as ABS or ASA, the lead screw can easily collect debris, hindering movement during homing
Check if the hot end is properly installed
During the homing process, ensure there is no external interference in the surrounding environment. Place the device alone on a table or floor and run the self-test again.
Check if the printer's Z-axis is operating normally and confirm there are no obstructions interfering with operation.
Check if the nozzle wiper at the waste chute on the back of the machine is damaged, especially the metal dome part. Normally it should protrude so that the nozzle can just make contact when passing over it. If the problem persists, consider restarting the printer and trying the Z-axis homing function again.
Clean the surface of the Z-axis optical shaft and lead screw with a lint-free cloth, and apply lubricating grease.
If the issue remains unresolved, check if there are any faults with the sensors and related components.
