If Z_RAISE_BETWEEN_PROBINGS is null or undefined the probe is currently not raised by home_offset[Z_AXIS] and zprobe_zoffset.
But when different from 0 is.

If an undefined Z_RAISE_BETWEEN_PROBINGS expands to 0 (and it does) this is the solution.


A similar asymmetry exists with the newly introduced 'short-cut' in G28 - but its the rise before anything is probed - so should not make a difference.
