8 years ago @Alex9779 I hear you, but I have a hard time understanding what is going on. Sry. Though, 2 things. You have Z_RAISE_BETWEEN_PROBINGS set which changes MBL in a way I am not familiar with (meaning I have not investigated how or what that does, but I think I can imagine what it is supposed to do). Then X_MIN_POS looks strange, shouldn't really matter but it looks off, but maybe your endstop is placed outside the bed like that?

I am trying to get the RCBugFix of today but I can't get it working anymore since the new probe options in the config. The problem is that after homing the bed is moved to Z=5. That is ok but when I start the mesh bed levelling the machine homes and rests at Z=5. Then I click to start and the machine does the Z hop move to the first position, undoes the Z hop but doesn't move to Z=0 instead goes back to Z=5. Z=5 is not yet 5mm away from the nozzle but about 7mm and the correct is limited to 4mm so I can't get the bed to the nozzle.
Do I have to change something in my config?
