Prusa i3 Pushes Through Endstops & Does Not Return / Marlin

When I press for example Y+ until it clicks my endstop on the backside / motorside it just continues pushing endstop. I cannot make it to return Y-. M119 says y_min triggered. If I try forward & then back towards me (Y-) Pronterface says endstops hit Y:0.17 . What's wrong & what I'm missing. Still confused with te logig..

All the endstops do same.

Usually the endstops are used at the MIN_POSITION.

So for now you click Y+ and your printbed is moving backwards (Y- direction) means that your axis is inverted.
Have you tried to "Home" it onces?

Still confused. I tried home once before X axis and it went crashing. Now I don't have same config, but I'm not interested to press Y home if it pushes against endstop and crashes?

Here I read
[www.instructables.com]

when we clicked the Y plus the bed moves back

So does my printer move. Y motor side Y- direction? I was thinking it is Y+ like in that instructables site.

Edit: when I look [forums.reprap.org]
it shows me motorside Y max endstop and right X max endstop. Z is min what I want so it prevents from crashing against glass? Has someone for this Marlin configure.h for me so I could test what I'm doing thinking wrong.

SOLVED as a wiring error in a dark room.
