Thank you very much to all of you. As x and y endstop are working, I tried the cable on z endstop and run M119 and the same result. So I ordered new endstop and have to be patient for it to arrive. Based on your help, I think this is the way to go, as the z motor works but if „it“ thinks it reached the limit, then obviously it won’t move. Well again thank you.

P.D. Once I tried, I will report the result.
