+The `dump_mesh` endpoint takes one optional parameter, `mesh_args`.
+This parameter must be an object, where the keys and values are
+parameters available to [BED_MESH_CALIBRATE](#bed_mesh_calibrate).
+This will update the mesh configuration and probe points using the
+supplied parameters prior to returning the result.   It is recommended
+to omit mesh parameters unless it is desired to visualize the probe points
+and/or travel path before performing `BED_MESH_CALIBRATE`.
