Slic3r using illogical bridging path

Hi, is there way to change bridging direction in Slic3r? I need to bridge small overhang (see picture) but slic3r just ignores support wall that I have put into the model just for this purpose. The longer bridge causes small bow which makes this part unusable because of tight tolerances. Thanks for help.

I've got the same problem, you can try this: http://shop.prusa3d.com/forum/print-tips-slic3r-settings-kisslicer-model-repair--f12/slic3r-and-bridges-t4519.html#p33244

Re: Slic3r using illogical bridging path

It is not working for me. In my case I think that slic3r is too "smart" and tries to bridge along the long side because there is a better anchor for the bridges (at least on one side.

I would love to have a override for that smartness...

Re: Slic3r using illogical bridging path

what about force an infill just below the bridge print settings-> infill under advanced. you can set a level to enforce a solid fill and that could help give the bridge above more time to setup and level a better top surface. Silc3r is limited compared to pay options where you can setup different infill %s and heat levels in separate areas of the same STL.

Slic3r can do separate infill types in different parts of the .stl. See mesh modifiers.

The latest version is even more powerful.

(But you can't adjust temperature in the mesh modifier, and you point out.)

Did you select "Detect Bridging Perimeters"?

The latest version of Slic3r (1.35.5.21) has Top/Bottom Fill Patterns that might help this issue.

Re: Slic3r using illogical bridging path

Ups, yes. Better in 1.36.

Remark to myself: NEVER name a icon "latest" 🙂

Re: Slic3r using illogical bridging path

Selecting the bridging angle is easy to change now. (I'm using Version 1.41.0+win64 of Slic3r Prusa Edition)
Right click on your object and select "Settings..." from the popup menu.
Click the Plus button
Click "Infill"
Click "Bridging Angle"
In the box that appears, type in the angle you want.
Click OK to save the changes
et voilà
