Autoleveling with Repetier constantly failing

Hello everyone

I am about to lose my mind. I have a RADDS / DUE board setup with a Z-probe on a servo lever. As required by Repetier 0.92.8 firmware I have a Z-max endstop to measure the z-length. All sensors return correct state when triggered, servo extend/retract is ok, all motors work fine. Here is the one unsurmountable problem now: I cannot figure out how to run G32 S2 command properly. It ends up telling me this in Repetier Host:

09:26:39.629 : Error:z-probe triggered before starting probing.
09:26:39.631 : Errorrobing had returned errors - autoleveling canceled.

I also posted a video here. First, I issued a G28 to home all axis, then G32 S2. Probe touched the bed, then moved to the right and then the alarm went off, the extruder started to move back up. End of story, end of ideas.

I have tried tons of different settings Z_PROBE_BED_DISTANCE, Z_PROBE_HEIGHT, changed Z_MAX_LENGTH - to no avail. I attached the config I used when I shot the vid.

Oh, and what I always do after flashing firmware is this series of command:
M502 ;
M500 ;
M501 ;

Thanks for looking into it. I am so DESPERATE.
