Nozzel to far from the bed

I'm trying to set up Z probing on my felix 3.0
I all seems to work beside that the nozzle is to far from the bed.
No mater what i try i won't get any closer
i use also use the probe as a z min end stop

this is my config file

    #define Z_PROBE_HEIGHT 1

    means when it triggers the nozzle is 1mm from bed away. Should be 0 or slightly negative value to compensate bending and switch distance. Remember it is in eeprom as well, so you need to change it there.

    When i disable the MIN_HARDWARE_ENDSTOP_Z  i can get the nozzle closer but not when i enable it
    If I a but a negative value for the height only 1 point gets measured before printing starts    .

    A z probe is no endtop. Both are handled differently. In some special cases you can handle it as zmin but it is never ideal. z min stopps when triggered and that is z=0. That is the definition of a endstop. You can go up a bit from triggering point also that would mean nozzle was below bed.

    I'm a bit puzzled here. You have the trigger in the nozzle right? So you heat up nozzle and the do homing and that should trigger only when you hit bed + trigger distance. Then you go ENDSTOP_Z_BACK_ON_HOME mm up again to stop at 0. So ENDSTOP_Z_BACK_ON_HOME must be too high or you are 
    using a cold nozzle and the old plasic causes a trigger to early. That is why 0.92 has now a new homing order Z up xy preheat Z
    to overcome that problem. Hope you use it.
