Thanks to DaveX!

What the arduino itself thinks is com3 is very different than what the host computer thinks is com3. You likely want your computer's com3 to talk to the arduino's com1
See and the Input Output section where "Serial 3" is on pins 15 and 14, which are what RAMPS uses for the Y endstops.
This sounds like this could be the problem... I have to try it out as soon as I have a bit of time

Thx for your reply first of all...
I changed the configuration.h file to com 3 (as it says in arduino program) Aldo changed the baud in between the two top values (something like 115k and 250k) none
