      Hello Everyone,

      Just an amateur question. Is it possible to drive an external tool, power high or low by 25v from the duet board ?

      Can we use the stepper motor drivers as a normal pin with the help of M42 commands. I know there is a possibility with expansion pin out but i have already used expansion header to drive motors. So i dont have the leverage of using GPIO pins.

      But do we have any other pins available on the board that i can turn on and off by sending commands to drive an external device (a cylinder for extruder extension).

      Can i use Fan1 PWM pin ?

      Thank you for the help. 🙂

        You can't use the stepper motor drivers as normal pins. You can use heater and fan outputs as normal pins if you disable the default heater of fan function on that pin first. See https://duet3d.dozuki.com/Wiki/Using_servos_and_controlling_unused_IO_pins.

          Thank you for the reply.

          Is the Fan pin capable of supplying 25v output ?
          I tried to search in documentation but could not find any point regarding this.

            Yes, when VIN is 25V.
