thanks for the reply vreihen!
It helped me finding the problem.
The endstops X and Y seem not to work.
I testet the connection of the wire and the mechanism of the endstops with a multimeter, they seem to be fine, but i dont get a signal to the program.
when i press the endstops and type m119, they stay the same.
Only Z seems to work correctly...
I did invert the endstops so all of them now get L when i do the m119 command, when i try to home it now all 3 carriages move.
Looks like i need a new ramps board...
