      Is there a maximum number of probe points that can be stored for mesh leveling?

      We have a 1 meter x 1 meter bed. When defining the mesh size in config.g, we have found that G29 will not even execute unless we reduce the number of probe points.

      So far, we've been able to probe around ~450. Are we hitting some sort of memory allocation ceiling by trying to probe more points than this?

      Thank you!

        When you set the size of the grid manually in the console using M557 it will tell you if you're using too many points and suggest a new spacing to maximize the available size.

            The maximum number of probe points in RRF for Duet 2 boards is 441. That's enough for a 21x21 grid.

                btw you could have found this out by looking up M557 in the GCodes wiki page.
