How do I add a physical buzzer to Duet board?

Not bad.
But an MP3 sound file which says "Please change filament", "Important message in the console" or "The filament spool is empty" etc pp is more elegant.
At least an MP3 file is easy to play, but the GFPlayer can play a specific MP3 file from the list, just HOW to control it with the Duet-Wifi without Arduino ?
Is that even possible ?
There are probably other uses that I can't think of at the moment.

The Duet (Smart Duet) of the future...
Duet, what time is this print ready?
Duet, is there enough filament for this print?
Duet, which layer is currently being printed?
Duet, turn off the bed heater!
Duet, Babysteps 0.05mm down!

@norder sounds like you need siri or alexa built in for that not an avenue I would want to go down....sure you can print this but just watch this advert first!

the SBC on a duet 3 would be the ideal I would of thought store the mp3 file on the duetpi SD card then reference it in a macro or setting for the Pi to playback plus the Pi has a speaker jack for better sound, not sure if that`s possible but it seems logical

@TomF @Norder you could use a RPi Pico with a few additional components to emulate a small part of PanelDueFirmware, connect to the PanelDue port and play MP3 files when certain events occur. You could start from https://learn.adafruit.com/mp3-playback-rp2040.

Wow, I'm amazed by the inventive range of ideas proposed by respondents to this post! Air raid sirens. Klaxons. MP3 tunes. Now, a buzzer sounds so yesterday. Thanks to all who responded.

I opted for the motor idea from @zapta with a few mods to the stl's so I can hang it at a jaunty angle on the back on my printer and have a flat on the shaft. I'm running some tests at the moment. Currently it sounds like a machine gun so I will make some adjustments to avoid anyone calling the police!

@tomf
Excellent !
I would like to see a video of that.

This version attracts cats rather than the police.

I just want to say I love everything about this thread.

@norder it is possible to create some interesting notifcation options with node-red and nodeDSF.

This potato quality video (sorry it's an old video now) shows notifcations on smart speaker, LG TV, and sending emails. But there are many more options available to you with node-red. nodeDSF will work with SBC or stand-alone board configurations over the network.

@mintytrebor
That is very interesting.
I'll take a look and see if it's something for me.
LG 4K Smart TV is available and serves as my computer monitor and is always on during construction and printing.

Thanks for the link, @MintyTrebor
Two of your PlugIn's are already running on my DWC, maybe there will be three soon ?

Thank you for your time and work on the PlugIn's.
