Buzzer



  • Hi,

    Since I was performing open heart surgery to my Duet 0.6 😉 I thought of adding a buzzer following this guide:

    Mind that the picture is pointing to PIN30 instead of PIN 32, so you have to move it one position to the left!

    At first I had a buzzer that does not seem to work on the low Voltage that is put on this PIN. with
    [c]M42 P67 S1 / S0[/c]
    I am measuring 2.7V / 0.5V. I ordered a new buzzer, but that one even sounds lightly in off-state (0.5V)
    Can someone explain where this 0.5V is coming from, and how I can prevent that?
