Negative offset z probing problems !
Hello,
I've been updating my old Hesine M505 (I3 clone) and wanted to add a spare BLTOUCH.
My bltouch work and nearly everything work fine except some essential feature :
when I hit home X or Y button, it goes to mecanical endstop then add the offset of the nozzle so everything fine
but when I hit home Z, X move in the X wrong direction from a few mm (offset is X -30 Y -15 and also in the eeprom)
for home all it's even worse : x goes to zero without adding offset, Y does the same and the BLTOUCH start the probing process far from the bed...
What can I do to correct this ?

G28 does work as expected
G28 Z0 after G28 X0 Y0 does not add offset.
Which version are you using?
I tried 1.0.1 and 1.0.1 dev
G28 = X0 YO then z up 1cm then goes down without offset. after z probing with my finger to avoid disaster, the nozzle offset is added... but not the probe offset
I need the nozzle and probe offset to be added before z goes down...
