      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%)

        M557 X30:180 Y30:180 P3:3

        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.
          Thanks again.
