Hey @all,

on my Radds with 20x4 Display the M300 Command isn't working anymore. The Beeper works if i turn the knob but with the g-code i won't get any beep?

Can anyone help me?

Edit: M120 is functional.

    anyone?

    That depends on your board and display/beeper. Both use different functions. lcd just turns it on for a while while M300 tries to make a sound with fixed frequency using the tone function. So this requires a free PWM for tone and a direct connection and not over I2C.

    M120 uses same as lcd so you should use that in case the tone version does not work for some reason.

    so, why was it working and now it doesnt work anymore after a firmware update?
  • RepetierRepetier
    Haven't changed it since it was added, so good question. Need to test it.
