    Hi all
    I was able to startup my Bigbox and the first time I pressed the button I frightened quite a bit because of the extremly loud buzzer sound. I wasn't able to find a setting to lower the sound - is there maybe a hardware knob to turn down the volume or can I completely mute it somehow?

    Thanks for your help!

    There is no hardware control I am afraid (other than leaving the sticker on you are asked to remove during assembly), you can quieten it by changing the duration and change the frequency (pitch) do it by modifying the firmware and uploading again.

    Look for the following lines in configuration.h

    #define LCD_FEEDBACK_FREQUENCY_DURATION_MS 2
    #define LCD_FEEDBACK_FREQUENCY_HZ 100

    If you lower the frequency a bit and reduce the MS to 1 it should be more pleasant. To mute it completely, just set MS to 0

    If you want to experiment with different settings before uploading then you can do it by sending manual gcode

    M300 S100 P2

    Would send a bleep the same as the one configured

    Thanks, Dr. Jeep. Glad to hear, that it is possible, but maybe I should postpone modifying the firmware to a later state. I want at least do a first print, before I crash the firmware. ;)

    When I would have bean clear about this, I would have decided to leave the sticker on the buzzer. It's a very, very small issue, but in my opinion, it is quite annoying and I don't see the point for having a buzzer for a button confirmation from user experience point of view anyway.

    But thanks again for your post. I think I will try to cover the buzzer with anything or modify the firmware at a later stage. I'll have to check how to do this though.

    @Greg Holloway I hate it that you did not change a version string or something to easyily figure out which version someone has installed. Only that date...

    Now that this has been said:
    There was a change in the firmware a few days before I got my box that covered some things. Among them was the buzzer sound. But unfortunately I can't tell you which version you have unless you can have a look at the info reply the box sends when being connected by a host application I think. Not absolutely sure it is in that reply either...

    @Greg Holloway Which firmware is on the boxes that leave you these days? Did you prepare all the RUMBAS before that last change or did you update them sometime?

    @Alex9779 We still have stock of boards with the original firmware build on them. When we do another run of flashing and testing boards they will have the newer modified code on them. There was only a date change as it's technically still the same version or Marlin and really only configuration changes.

    @Greg Holloway yeah cool no problem :)
    Just wanted to know what to tell @Tetrikus if he still has the original release then a simple firmware update would be good for him to see if the sound is still so annoying.
    And then we can advise him to do changes tasting with code and maybe compile an own firmware...

    So @Tetrikus in your position I would first get the newest firmware from the repo and try the one with the updated configuration out...

    I forgot to take the sticker off the buzzer........... believe me it makes NO difference, still loud enough to wake the dead.
