    g2 shield m1_step pin is attached to DUE pin 2.
    Arduino DUE pin 2 is low current pin. Max current output is 9 ma.
    When step frequency getting high, stepper driver is not saturate enough!

    My offer is use SAM3X8E C Port for maximum secure stepping. C Port Pins is power current output.

    Are you using Gshield on DUE for motor drive or external drivers?

    You should consider a 3.3v to 5 V logic buffer for all external driver interfaces.

    Or, you could make the pin change you suggest in Motate and recompile.
