Copied the file to the SD card and started the process of printing.

The printer is in a room where the door is normally closed. I was "called" by the filament change. I barely heard the sound. Maybe other frequencies could be used because you can fall asleep next to the door and you won't hear anything :-)

I guess this is something to change in the firmware as it is repeated until you actually change the filament.
Anyway, a new filament was correctly inserted but unfortunately the LCD display was "covered" with meaningless characters.
I knew by experience I had just to click on the button to confirm the change.

Are there any problems with the serial port? I am running Firmware: 3.0.12

Another thing I noticed: Just before moving quickly back to the object, the extruder spits another 2-3 cm of filament.
You have to be quick to remove it with a tweezer before it's above the object. You really cannot sleep...

Is it as well related to my firmware?

Anyway, I had some fun color printing.
