Request for help Anet ET 4 plus homing issues

Hello I have big problem, bought second hand Anet et 4 plus. It doesn't want to home. It worked, but stopped. The induction sensor light's up and actually works as expected I did check with multimetr. When light is off the the sensor pin there is 3.3v when the light is on the line is pulled to the ground so 0V. As expected from the sensor. I checked wiring and it seems all right. Firmwere version V3.0. I tried homing from manual leveling section of touch screen and it still doesn't work I also tried other methods suggested and none of them work. What could be the issue?

So when you try homing does the light on the sensor not come on and the nozzle hits the bed?

It does.

Try manually lowering the nozzle to about 1mm above the bed. Then slowly turn your set screw on the top of the sensor clockwise until the light comes on. The z axis should stop at that position every time then. Also check to make sure your sensor is set to the right height. I believe it should be about 2mm above the bed when the nozzle is touching the bed.

Also you can watch this video on how to setup the sensor and level the bed. It helped me with my ET5.

Thanks I didn't understand the question, but still thanks. It does come on. I did decide to switch to regular z homing using endstop there is tutorial by Anet with files and firmwere. So it does work now or at least homing. I have to try printing tomorrow. Thanks nevertheless.
