BLTOUCH probing

[printingmark]

Hallo everybody, hope you are doing well
i have some problems with my BLtouch, due to conect problems i had to put a backup back on the board, now if i try to probe the bed the first two probes are oke the thirt probe it hits the right site before probing and back on the left side it tries to probe ousite the bed, what could be wrongconfig.g
thanks

It will likely be in this part of your config.g file.

G31 P25 X-31 Y0 Z0.6                               ; set Z probe trigger value, offset and trigger height
M557 X20:215 Y20:215 S64                           ; define mesh grid

Likely the X-31 is no longer accurate. With the probably area being X20-215 and a -31 offset it could still probe 11mm off the bed (I think). But those are the parameters that you need to adjust to get the probe back on the bed.

Whenever changing the probe you should redo your offsets

And as @baird1fa says you should verify that your M557 is taking your probe offsets into account so that it isn't trying to place the probe where it shouldn't.
