Z Axis Homing Problems

Hey,

I have an Prusa i3 Printer wiith Repetier-Firmware 0.91 and I have a problem with the homing of the z Axis. When I press home Z Axis in Repetier Control the Z Axis moves down and stops a a random position and does the homing there. I tried to disable "Always check Endstops" but this also won't work. X and Y axis work propably.

I hope anyone can help me.

    "Always check Endstops" works only while printing, during homing we must check endstops for logical reasons.

    I think it is cross talk, so you could either twist your z sensor cables to prevent it or switch to latest 0.92 where we have a new endstop check routine that normally filters these wrong pulses. Only very rarely it will get 2 wrong pulses in a row fooling the system.
