Duet maestro Z probe not triggering

  • I have just hooked up my inductive sensor to my board and put in the new firmware but when i test my probe the value always stays at zero. when it senses the bed the probe light does go on. i have wired it according to the most recent diagrams for NPN sensors so i believe my issue is somewhere else. I am using a 1n4148 diode as the duet page says.

    also, when i use the M119 command both on and above the bed it says the probe is not triggered and i have checked to make sure the direction of my diode is correct.

    Might there be any other readily available diodes i could try because i don't have a bat85 or 43 on hand.

    can anyone help point me in the right direction.

    How have you configured the probe in the M558 command in config.g?

    Which pin of which connector on the Maestro did you connect the diode to?

  • I figured it out, thank you for the reply, the diode i was using was the smaller signal diode and i was not sufficient enough. I have a BAT85 now and it works perfectly
