Incorrect single width bridging

I had bad bridge path when the bridge is thin and needs only one travel. So I designed a test object:

Which when I slice with these options:

Prusa Slicer 2.3.0 produces this:

Notice that the thinnest bridge starts from where there is nothing below it and ends in where there is nothing bellow. Finally this prints as:

Detect thin walls is known to be problematic.  What does your part slice like with it turned off ?

It produces two paths. The bridge will be ok but then the size of the bridge is not correct.

RE: Incorrect single width bridging

Could you post either the part or your project file (3mf) please.

In case you are not aware the forum is VERY picky about what file types are allowed to be attached.  Neither stl or 3mf files are allowed which is great for a 3d printing forum.  You will need to zip into an archive or rename the 3mf file as a .zip to allow it to attach.

I think you are falling foul of this issue https://github.com/prusa3d/PrusaSlicer/issues/5665   but with your file we might be able to do a workaround.

Here you are! The extension is in the name.

Test bridge-3mf

Test bridge-stl

I designed the part pretty small to not waste too much filament during the tests. If you want bigger part please let me know and I'll do it!
