Maestro Z_PROBE_MOD (zprobe.mod Pin 3 Servo pin 11)



  • Hello,

    I have been looking to maximise the IO on my Duet Maestro board.

    I have set up two relay modules connected to zprobe.mod and Servo

    using the closest GND ,+5V to pins 3 (zprobe.mod) and pin 11 (Servo)

    The problem I'm having is both relays come on with zprobe.mod and servo doesn't respond to any code.

    using

    M42 P3 S1

    brings Both relays on along with the diag LED (diag LED is directly connected to zprobe.mod)

    M42 P4 S1 or S0 has no effect.

    it seems to me that they are directly tied to each other, is there any way to separate them?

    Snippet from my config.g below.

    Thanks
