Replace Zmin endstop by Z probe

Ben3DBen3D
in General
I would like to add autobed leveling to my Zonestar P802M (prussa i3 clone). 

But what i was wondering if i replace my endstop by the probe how can i iniatialy home my system?
If i home X then Y and the Z the probe will nog be triggered.

It should home the Z when posioned above the bed (let`s say center)

thx for the info!!

    you can use the probe as te Zmin endstop,
    In config tool
    under mechanics
    Use 'homing order' Z up X Y preheat Z
    set location for 'XY Homing pos. for Z' (set to centre of bed)
    Keep zmin endstop as normally open or closed depends on type of probe
    Z min pin= z min endstop

    Then in features
    tick enable Z probing
    Assign Z-probe pin as Zmin pin
    setup your probe offsets and probe points
    and test

    Thx, i managed to find that i need the DEV version.
    Now i have the issue that is does not fit on my melzi board.
    I need to reduce the size of the firmware, i do not need the SD card support. But how do i remove it from the compiles code?

    Uncheck "Enable sd support. Gets overwritten by ui-controller or board settings.". If you have also LCD you might need to edit in DisplayList the variable setting it on. SD Card is a bit tricky as it can be enabled at different places as side effect.

    But how to do this in the arduino code? do you have an example?

    Normally you use our config tool and uncheck the languages you do not need and recompile. Manually edit configuration.h near end you can set languages included.

    I disabled arc support and know it compiles :-)
