      @User3D does your slicer issue any speed commands that override it?

        @engikeneer I just checked gcode file and found out that it does contain command to set feedrate to a greater value.
        When I am setting max speed using M203 then speed should not go beyond it irrespective of whatever feedrate I set in G1 Fnnn .

          @User3D Can you share your config.g file and config_overide.g file if you use one. Also, the section of the gcode file that you are printing up to the first few print moves. Better still, upload the entire gcode file to Dropbox or Google drive so that we can see the whole thing. And tell us what max speed DWC is reporting while doing that print.

            @deckingman I even observed today that when I don't set feedrate and run my axes , it takes feedrate set in paneldue. That feedrate is 6000 and my max speed is 5100 and on giving commands, axes are actually going upto 6000 (confirms DWC). This should not happen.

              1. Post your config.g file.
              2. After observing the speed being higher than you think you have set, send M203 without parameters to see what speed limits it reports.

                  Please provide a screenshot of DWC showing excessive speed. If your PC runs Windows then you can use shift-Win-S to do freeze the screen and get a screenshot. Also a shot of the M203 report please.

                  Which firmware version are you using?

                      What was the move that you are executed? If it's a Cartesian machine, then as both X and Y can move at 5100mm/min simultaneously, the combined speed of a diagonal move can be higher, up to 5100 * sqrt(2) for a move at 45 degrees.

                        Got it. This is happening on diagonal moves only. Thank you.
