      Hi All,
      I want to prevent the mesh level routine from trying to mesh the centre of my polar printer. Is there any way to exclude this when defining the mesh.

      Ideally I'd like to set custom mesh points so it meshes by using several concentric rings, but it looks like custom meshes aren't supported any more?

      Using the M557 R method just appears to create a Cartesian meshes inside the defined radius.

      Any constructive thoughts would be much appreciated.

      All the best.

        @cncmodeller currently defining custom mesh patterns is not supported so have moved this post to the firmware wishlist.

            @cncmodeller that should already be taken care of by function IsReachable in file PolarKinematics.cpp. Any point that is less than the minimum radius from the centre (the first R parameter in the M669 command) should not be probed.

              @dc42 Ahh ok that makes sense. I've been using min R as zero since I never change it from when I was tramming in the printer. I've now set it to 50mm all seems good.

              Many thanks
