Add a buzzer notification

[jccg315]

NFC scanning didn't prompt me to check the log. I added hardware such as a buzzer and a gcode-M300, but I don't know how to make an NFC trigger sound.

Either you update the gcode macro for SET_ACTIVE_SPOOL so it calls your new gcode.

If you use this file: https://github.com/bofh69/nfc2klipper/blob/main/klipper-spoolman.cfg then add a call to your new macro after line 10.

I don't remember if klipper needs to be restarted after you change the file, but I would suspect it does.

You can test it be calling the SET_ACTIVE_SPOOL by changing the spool in the webpage, that will cause it to beep too.

To just have it be called when a NFC tag has been read, not due to changes in the webpage, you can change the nfc2klipper config file (https://github.com/bofh69/nfc2klipper/blob/main/nfc2klipper.cfg):
change the setting_gcode under macros like this:

[macros]
setting_gcode = """
SET_ACTIVE_SPOOL ID={spool}
SET_ACTIVE_FILAMENT ID={filament}
<your macro here>
"""

nfc2klipper has to be restarted for this to work.

By default nfc2klipper doesn't send those gcodes if the same tag is read again, to change that you should change the always-send to true.
