I have a strange issue.. when i want to home X Y and Z, X and Y works ok but Z only goes up a few millimeters. if I keep homeing, it crashes against the stop sensor.

I have not been able to get this to go.

Hello I hope I can get help. I have a fully assembled rostock mini from geetech using repetier. I uploaded the latest firmware and the machine seems to be properly assembled. When I click to HOME and I place the spider at the middle of the rods, X and Y finds home with no problem but Z only moves up...
