    I need some advice. I need to level the two Z axis before doing G32 and G33. 

    My initial thought are:
    G28
    G32 S2
    G33

    But this should only be performed when I have reason to believe its off. How should I do the daily/between prints homing? Maybe G28 and a G30?

    Setup:
    - Dual Z stepper with dual Z max endstops. 
    - IR Z-probe with no defined Z min endstop.
    - Homing towards Z max endstop

    I only use G28 for all printers having autolevel. G32 S2/G33 store everything in eeprom so these data stays active and unless I do some action which might change bed level I see no reason to repeat this procedure.

    Yes, but what should I do for everyday printing? E.g. in startup GCODE?

    I do a G28 that homes Y min, X min and the dual Z max (Takes a while) and thats it? I should trust the stored Z?

    So my Z-probe should not be used for every print?

    If so I need to do all initial probing at printing temperature.

    Yes trust it! G32 S2 stores all adjustments needed so G28 has them on next homing as well. Most important thing here is that with z max homing you need 
    ENDSTOP_Z_BACK_ON_HOME 2

    so endstops are not hit while moving xy at z max making position invalid.
