Struggling to get 3 x 3 bed mesh for probing

How does what I put in into "Define are for grid mesh compensation" relates to the M557 in config.g?
Error: G29: No valid grid defined for bed probing when putting:
M557 P0 X30 Y30 ; define mesh grid
M557 P1 X110 Y30 ; define mesh grid
M557 P2 X180 Y30 ; define mesh grid
I want Duet to create a 3 x 3 grid for probing the bed. I have a mirror which is almost flat and don't need the ±42 probing points.![0_1599509962342_bed-mesh#2.png](Uploading 100%)

That assumes the values 30 and 180 are appropriate for your setup.

@fcwilt thanks for your reply.
I am very new to 3D printing and a week into Duet.
My bed 's (mirror) printable size is 220 x 220.
I will quickly try out as per your suggestion.
