Printer homes correctly, but starts printing too high (no replies)

Hi,

unfortunately I have another problem with the Marlin firmware (v. 1.1.9) which I can't figure out by myself or searching on the internet.

When starting my print, the printer homes correctly (endstop, no homing probe), but then raises the z-axis before starting the first layer. I tried adjusting the Z_PROBE_OFFSET_FROM_EXTRUDER 0 in Configuration.h, but without success, the printer only started even higher or at the same height (also when putting in negative numbers). Have I missed some other configuration point?

Thanks in advance.
