My 2 year old Creality CR 10S-Pro doesn't work.
It has original firmware and sensor.
When I press the "home" button, it goes to the middle of the bed. The nozzle goes down towards the bed and turns just before, goes up a bit and now slowly goes down towards the bed. A third time it goes up and turns down. It continues downwards, the LED on the sensor starts to light but despite that the nozzle continues and goes down into the bed ....
Could it be a faulty sensor, cable fault or ......

I have got advices but since I am a beginner at this I don't always understand how to edit g-code and similar.
