①Please use a metal object to put it under the proximity switch. If the red indicator light is on, it means that the proximity switch is normal; otherwise, it means that the proximity switch is abnormal.
②Please check whether the wiring of the proximity switch on the main board is plugged in properly. The wiring may fall off due to transportation, and you can rewire it.
③If the above two methods cannot be solved, there is a high probability that the problem is the proximity switch. Please submit the final investigation result to the after-sales engineer.
During automatic leveling, the PEI spring steel plate must be placed, and it cannot be replaced with a non-metallic platform, otherwise the proximity switch cannot sense the metal, and the Z-axis keeps moving down the pressing platform.
The above troubleshooting methods cannot solve the problem. We suggest you create an after-sales ticket and our After-sales engineers will help you solve the problem. (Reply time :1 working day)
