Long Bridging - supports don't appear needed?

Long Bridging - supports don't appear needed?

I selected support on print surface only and this still slices with very long bridging.  Is there a way to rotate the bridging so it's not so long or force supports?  The subsequent layers print fine and build up so this part looks good, but I still have those loose bridge lines.

 

Appreciate any input!

You can rotate bridging angle in Print settings / Advanced / Bridging angle :

It is normally set to 0, but you can set it to what you want to get the best prints, but only if you have sides all around.

Two posts with bridging set to 90, just aint likely to work, but I'm curious now I have made that statement.

Off to try 😀 

Normal people believe that if it ain’t broke, don’t fix it. Engineers believe that if it ain’t broke, it doesn’t have enough features yet.

Excellent - thanks!

Found under Print Settings > Infill -> Advanced -> Bridging Angle

90 degree rotation is perfect!

I will say your long bridging was amazing.

I've been looking for that! Another PrusaSlicer feature that's not well documented. Good find!
