I would like to have a short M300 "beep" when the "real" print starts (only before the first production move - not at the first homing, etc) to get my attention when the first layer is printed.
In my start gcode in Cura this works fine when I insert it after the M109 command. But to have it also in already sliced files I would prefer to have it in the OctoPrint gcode "Before print job starts".
So I think I must use some conditional like "if hotenend-temp is reached" to realize that.
I read about this "last_temperature" thing in the docs, but have no clue if - and when - how I can use this.
I'm grateful for any help in this.
