I'm get the same behavior on bed leveling G28 and G29. Both Gcode execute as expected but the point of the hot end its over the bed about 5.1mm in my case, and report as Z=0 when M114 is sent. I tried to modify the z offset to less but the gap always is the probe when deployed. Resuming: After the bed leveling process didn't get down the hotend point to print position, It remain on the level after probe retracts. My config is prusa i3 with sg90 servo, sanguinololu 1.3a and panelolu2.
Sorry for my english
After a few tryouts I have been able to print something with autolevel routine.
I went to get a old version of marlin (two monts ago or so) and modify to bed level, and it works after all. With the latest ErikZalm Marlin from Github I can't get to work. Also its a bug compile as downloaded... check this out.

He activado la auto nivelación siguiendo las instrucciones y la altura del hotend me salía -8.4.
define X_PROBE_OFFSET_FROM_EXTRUDER -22
define Y_PROBE_OFFSET_FROM_EXTRUDER -26.7
define Z_PROBE_OFFSET_FROM_EXTRUDER -8.4
El problema es que cada vez que hago un homing me dice siempre que la altura es 3.20. He probado aumentando el 8.4, y no cambia nada.
La cama me la nivela bien pero siempre se queda el hotend muy separado de la cama.
