Okay, Thank you so far. I already had set this parameters before. When I start G29 the pin get pushed down in the second repetition too early and hits the bed. Then the BL-Touch starts to flash with a red light.
The crazy thing is, that its still doing the 2 repetitions but I set just 1.
Is there a possibility to change something in the Repetier Host?
/* Z-Probing /
/* After homing the z position is corrected to compensate
for a bed coating. Since you can change coatings the value is stored in
EEPROM if enabled, so you can switch between different coatings without needing
to recalibrate z.
/
#define Z_PROBE_Z_OFFSET 0 // offset to coating form real bed level
/* How is z min measured
0 = trigger is height of real bed neglecting coating
1 = trigger is current coating
For mode 1 the current coating thickness is added to measured z probe distances.
That way the real bed is always the reference height. For inductive sensors
or z min endstops the coating has no effect on the result, so you should use mode 0.
