Ok but As far as I know it's extruders pin. So wouldnt it make a problem ?

Thanks for your reply I am using heater 7 as my pin so i think I should change servo pin but I don't know where it is mentioned.

Hi I bought a Duet Wifi board and 3D touch probe. I am trying to to configure it and couldn't manage to do it. I am using a reprap version 3.2.3. The problem is it blinks and sweeps several time then I send the gcode but it doesn't respond to it . I will be giving my config deploy and retract probe codes. I don't have any override file Thanks for Help.
