[QUALITY] Allow custom bridging angle/infill like SuperSlicer

Which printers will be beneficial to this feature Everybody

Describe the solution you'd like Be able to change the bridging angle, allowing it to look cooler when a face with bridging is exposed like so.

According to the post, these are the SuperSlicer options to archive that nice effect.

Print Settings
  -> Perimeters & Shell
    -> Advanced 
      -> No Perimters on bridge areas - Keep Only bridges

  -> Infil
    -> Advanced
      -> Angle 
          -> Bridging - 90 (set this based on parts orientation to make it look the best)

  -> Width and Flow 
    -> Overlap
        -> Bridge Line Density - 50% Min, 50% Max
    -> Flow
        -> Flow Ratio Bridge -  85% 

I do understand that "No Perimters on bridge areas - Keep Only bridges" and "Bridge Infill pattern" might no be an easy task but allowing the bridge angle to be changed should be a fairly "easy" implementation.

That also should prevent the infamous bridging belly. This is the current way, both layers on the same direction so a lot of material concentrated within the same space. The example above, the next layer is crossed distributing its weight across many lines instead of 1-2 lines so it is lighter.

Describe alternatives you've considered Cry :)

Additional context Pleeeeeeease!!

@Noisyfox yeah, I need to book an eye check... I got the first bridge to do that but it only applies to the first bridge

The second bridge remains the same. I am guessing because of "50% Min, 50% Max" which OrcaSlicer seems to be only applying one (???) Any idea why of these weird idk what on, at the corners?? I have noticed these weird stuff everywhere on prints, especially the ones with low wall counts. I am opening a bug for that one, no logic explains it.

Thank you

"Detect narrow internal solid infill" solved those weird concentric stuff. Thanks for that Noisy

I'd also like this. I have a similar problem with Top/Bottom Layers (Skin), opened a bug report... https://github.com/SoftFever/OrcaSlicer/issues/1515#issuecomment-1794798789

i have similar problem

orca on the left, superslicer on the right. orca makes concentric moves on the bridge.

Make sure the "extra perimeter on overhang" option is disabled.

Make sure the "extra perimeter on overhang" option is disabled.

I disabled the "detect overhang walls" and it made it rectilinear movement.

It is not the extra perimeter on overhang. ( Cannot see the difference enabling or disabling this setting or am i not just looking at thr right place?

Orca bot: this issue is stale because it has been open for 90 days with no activity.

also interested in bridging angle adjustment

The superslicer setting mentioned here, "no perimeters on bridge areas" sounds like it would solve or at least let users work around the persistent issues (see for example #5724) of bridge perimeters printing with either

• normal perimeter speeds when "detect overhang walls" is disabled, which usually is either too slow or too fast
• 75-100% overhang speeds when "detect overhang walls" and "slow down for overhangs" are both enabled, which almost certainly is way too slow
