Interesting discovery, I started a longer print job and found out (too late for cancelling and starting again) that I had left the printer in stealth mode.
I changed it to normal in the LCD menu Tune - Mode but even though the screen says it is in normal mode, it carries on in stealth mode.
Perhaps something to look into in a future version?
This is really something you need to take up with Prusa. It's the firmware that controls that stuff, and I'm not even aware of any kind of commands on the serial interface to influence that behaviour.
I know this is somewhat off-topic, but I have been noticing that with Stealth Mode and built-in Timelapse(set to layer change)β¦ the file is corrupt and cannot be played. But in Normal Mode, the files are perfectly fine.
