12864 Display error/end of print beep-beep-beep...

CNCModeller

Hi All,
Is there any way to used the M300 command to play a continuous beep, beep... sound continuously via a 12864 display when either the printer has paused due to an error, or the print has finished?

I thought about using a meta gcode loop in the pause.g or equivalent "PrintEnd.g" (don't know the correct filename) file, but then thought it might already be in the firmware. I can't find a reference to a pre-existing approach at the moment. Cancelling the alert would obviously need to stop the beeping lol.

Any constructive thought s would be much appreciated.

Many Thanks

I just call a macro as part of the end gcode.

Thanks @Phaedrux , but wont that stop after the specified number of beeps? I'd like it to continue until someone comes to see what's up...

Ah, I see what you mean. You might be able to setup a conditional loop for that, but that's not really my forte yet.
