Can't enable "Detect Thin Walls"

I'm hoping this is super simple.

 

I have 2.5.0 and in the advanced tab. For some reason I can't check the box for "detect thin walls". I'm assuming I made a change to something that effected the ability to do so. However, even going back to the original prusa presets (0.20 Quality, Prusament PETG, Original Prusa i3 MK3S & MK3S+) I still can't enable it.

 

Are there any settings that prevent me from enabling "detect thin wall"? Any help would be appreciated.

 

Thanks

Yes.  From 2.5 onwards the default slicing engine is now Arachne.  That varies extrusion thickness to get a 'best fit'.  Of course how well it works is an exercise left for the user to decide.  It has its own set of settings and as such is not compatible with detect thin walls.

Change Print Settings>Layers and Perimeters>Advanced>Perimeter Generator back to classic and you can then enable the detect thin walls. 

Don't know why you would want to anyway as that particular setting has always been error prone.  Far better to make sure your walls are actually thick enough to print in the first place modelling wise than to rely on software that often gets it wrong and prints thicker anyway.  If its going to print them thicker then you might as well model them that thickness to start with.

Well, the reason you'd want to be able to enable it is when Arachne fails to detect thin walls and leaves you holes in your model. And sure, if you're printing something you designed, it's best to design it to be printable. But if you're trying to get someone else's model to work at the edges of the capability of your printer, sometimes detect thin walls works better than Arachne.
