The BIOS says parallel port mode ECP so I gues its not that but there are some other settings for the serial port in other menus like OnBoard Serial Port A: Auto/Disable/Enable. And in another sub menu I can chose Auto/Disable/378/278/3BC can it be something with this settings?

Serial port has nothing to do with Mach, or at least with your setup, it is the parallel port that is used.

Ok, well than it is just Auto/Disable/378/278/3BC. I dont think it is the wiring of the cables because now I have switched the pins in motor outputs so Axis B got pin 7 and 3 and than that motor got the problems that the axis locks so the problem always follows the pins 3 and 7

No I think it is the stepper motor which is corrupt. I switched position on Z and Bs connection on the board and the problem did follow the motor

You need to set the pins to the way it was last night, the pins are hard wired to each axis on the driver board and you can not change them, you can only tell Mach which pin does what.
When you set them back then disable all but the X axis and try that. If it works then disable X and enable Y and test, do the same for each axis making sure the one you are testing is the only one enabled.

Well I did change the settings back like it was and then I unplugged the wire plug on the Z motor and try it on every cable and it was always the same and when I try another motor on pin 7 and 3 it works just fine so it must be the motor I think.

Ok that does sound like a bad motor. Make sure you have it wired correctly, sometimes the colours on these motors are different from normal, it could be you have the coils wired wrong. If you have an ohm meter you should be able to work out which coil corresponds to which wires.
