I’m now seeing this error since the latest Bambu Studio update. Anyone else?
appears to be an “improvement”
Yep, get the same message. Printing PLA so I assume it’s just a reminder to keep the door open (or the lid off).

Yeah it’s a new warning in the system. See improvement #2. 
It’s not an error its an aid
Found it. If the bed temperature is set higher than the softening point in the filament profile, you will get this message. Go in and change the softening temperature in the filament parameters to a number 3-5 degrees hotter greater than the highest bed printing setting you’ll use for tat filament when printing. if you don’t know what the actual softening temperature is
