      M92 X1280 Y1280 Z1320 ; Set axis steps/mm
      M350 X256 Y256 ; Setting microstepping to 256.
      M350 Z32 ; Setting microstepping to 1/32.

            @patel said in steps/mm did not match:

            M92 X1280 Y1280 Z1320 ; Set axis steps/mm
            M350 X256 Y256 ; Setting microstepping to 256.
            M350 Z32 ; Setting microstepping to 1/32.

            That will:

            1. Set the XYZ steps/mm according to whatever microstepping is set at that point. the default is x16.
            2. Change X and Y to x256 microstepping and multiply the X and Y steps/mm by (256/16)

            If you are going the set the steps/mm at x256 microstepping, the M92 command must come after the M350 commands, not before - just as the online configurator generates it (I just checked).

              BTW we do not advise using native x256 microstepping except in very specialised applications where only slow movement are needed, because the high step rate needed is likely to overload the processor. X16 microstepping with interpolation works well in almost all cases, except that some ungeared extruders with low E steps/mm benefit from x64 native microstepping.
