when i push the x(+) button it moves to (-) direction.
the other axis(z and y) dont have a problem.

what is the reason of this problem ? how can i fix it ?

you must have wired the x motor different,maybe couple wires switched
but just go into mach under motor reversal and reverse the x motor,easy fix

Check and or clean your main cable connectors to that axis
