Z Axis not properly homing

[Maximilian]

Hello,

When trying to use the homing function in repetier host the x-axis and the y-axis work fine!
But the z axis just moves down around 5centimeters and then stops for no obvious reason (it is not hitting the stopper or anything else)
I hope someone can help me I already tried changing the homingspeed

You need to check your wire at first.
Maybe it is the wires problem.
You can attach it if you don't know how to check it.
