Set Pin 66 on high

Hey everybody:)

i got an Arduino Due with Radds and an extension board. Unfortunaly some stepperdrivers wont work on the extension board. So i measured the voltage and found out that Pin 66/25 got 0V (those are the VDD pins). So my question is: how to set them on high?

i appreciate any kind of help.

cheers Simon

    would set it high. If that works you can add that to the start gcode

    #define STARTUP_GCODE ""

    That way it is always enabled just like you need it.
