I have a problem with auto bed leveling. It only probes the front half of the bed.
Do you have any idea what I'm doing wrong?

...tell us about the firmware you use and the offset between nozzle and sensor. (positive or negative offset?)

When i set the offset between nozzle and sensor to 0:

#define Y_PROBE_OFFSET_FROM_EXTRUDER 0 // Z probe to nozzle Y offset: -front +behind

It is probing the bed completely!

???

Maybe the probing point + offset is outside the defined bed limit, so the controller skips all these probe points?
