Description

Probe offset wizard should measure the Z offset at the same point at which the probe homed.
With Z_SAFE_HOMING and PROBE_OFFSET_WIZARD enabled, the probe offset wizard autohomes, probes the center point (Z_SAFE_HOMING_X_POINT, Z_SAFE_HOMING_Y_POINT) of the bed and without moving in XY waits for the user to manually lower the nozzle to the bed and establish the Z offset. Given the bed is not perfectly levelled and the nozzle is lowered at a different point than the probe (NOZZLE_TO_PROBE_OFFSET), there could be a significant error in the measurement.

Feature Workflow

After homing and before the user's measurement the carriage should move to (Z_SAFE_HOMING_X_POINT+NOZZLE_TO_PROBE_OFFSET[0], Z_SAFE_HOMING_Y_POINT+NOZZLE_TO_PROBE_OFFSET[1]), so that the nozzle is above the same point as the probe was.

No, sorry. It was actually resolved in #20239.
