        In the web page for your duet board, DWC, click the Auto Bed Compensation

        0_1558126523444_d3733dfd-ac02-449a-8f59-55dea6c05e0e-image.png and if you click the button it will probe the bed.
        From the dropdown you can configure the grid.
        Make sure in your slicer you include 'G29 S1 ; Get mesh' in your start GCode.

        HTH

          ok thank you so now im having a problem with my bltouch it seems to stutter when i probe the bed as if there is a voltage drop on the magnet in it or something so it gives me an error Error: Z probe readings not consistent
