Prusa I3 Pro 3D Printer does not set the home

[RodolfoReno]

Soon I bought a Prusa I3 A 3D Pro pro and I can not set the Z axis home set, when opening the Repetier-Host and pressing the Z axis home it does not go down until the end of course button, it just set where the Axis is like zero, when trying set by the LCD when choosing the option of Auto home the X and Y axis work normally, since the Z axis only rises and does not lower until it touches the end of course, someone knows a way to solve this problem? Thank you

Did you fix it?
I guess the endstop on Z axis didn't have good connection or it wasn't plugged to the right slot(Z_min).
