Okay first off this is not a question, and i am sorry if this is inappropriate, but a tip if you wanted something like this always.
Did you know that you can send the Z axis all the way to Z max everytime with Gcode?
G53 G1 Z #<_ini[AXIS_2]MAX_LIMIT> Fxxx (this would be something similar to Heidenhain´s M140 MB MAX)
It will send your spindle always to ZMax, even if you change the Softlimits later (otherwise either the spindle may not get to Zmax or will error out saying Softlimit would be overshot) The benefit is that if you have some .ngc files with known values for z Max (for example G53 G0 Z151) or your postprocessor spits out something like that, you wont have to edit each file when you have to change your softlimit.
if there would be any disadvantage i havent thought about let me know.
just a tip
