PSlicer 2.7.0 - odd/false? Low bed adhesion warning

Hi All

I updated to 2.7.0 and get a 'Low bed adhesion' warning on a print that is flat and has a very large amount of bed contact.   While it doesn't cause printing issues and is easily ignored.  It could suggest a problem with the warning algorithm.

Or I just don't understand the warning, if so please enlighten me.

Picture and the project file attached.

Can’t really tell from the pic but the project didn’t attach. You need to zip up files when attaching or the forum silently just doesn’t. Always best to confirm after posting as the edit window is only a few minutes.

That did not work either... I will try a different way: https://drive.google.com/file/d/17d9iU7lcTf8q0n__kwKmoefoPiVzAcNf/view?usp=sharing

RE:

I suspect its reacting to the bridged areas and the long thin sections from those parts on the left for the brim suggestion.  Traditionally shapes like those are primary candidate for contraction forces and can be pulled up from the bed as layers are added.  
Especially considering your part placement so close to the edge.  Edge areas are going to be cooler than the middles.  Notice the auto arrangement still keeps it within 6 of the heating panels but moves the parts away from the very edge.  That isn't by accident.

The supports suggestion for the bridged areas is a  complete false positive imo.  The worst printer in the world should be able to bridge gaps that small.  

Guess that's why I have that warning setting turned off lol.

Thanks Neophyl

 

I can see the thin areas triggering the warning.     Printing in the middle of the build plate if there are problems is good advice.    [but they all printed fine, so no need here]

 

Agree bringing warnings can be suspect.   

 

Appreciate your insight!
