Kossel Repetier FW Z-Tower not moving down

Hi Reprappers,

I switched to the Repetier Firmware for my large Kossel.
But now the Z-tower will not move down. it goes up when homing en shows in the display X:0 Y:0 Z:373. But i won't come down.

In Repetier it shows the Z height in red as soon as it get changed.
I changed the motors and the motor-drivers but that didn't solve anything, so it must be in the config:

I don't know if this is correct but i set the XYZ towers as ABC.

.... 2? Seems a bit... small.

Changed the max z feedrate but it didn't change anything.

Seemed to be a endstop problem with the z min endstop.

Now my question is do i disable this z min endstop completely and what will be the effect on the z-probe/auto-level when i do this?
Will it still work when i set the z-probing to use the z-min-endstop?

Thanks in advance,

Peter

x/y/z min endstops are independent from z-probe micro-switch in Repetier.
Disable x/y/z min endstops in configuration.
Set z-probe pin to one of (now free) x/y/z min endstop pins.
E.g. I set it to 3 for my RAMPSv1.3 (which was originally x min endstop).

Yep! That was the solution, Thanks!
