Expert Mode? Really?  

RE: Expert Mode? Really?

This is a user-to-user support forum, is there any point to this that anyone here can help you with? In which case a few details would help, such as a 3mf file that would show us why you think bridging angles are non-functional? (needs to be Zip compressed before uploading; yes…. zip compression required in 2025?? I know…. the forum software just sucks).

RE:

Sorry but not sorry about being frustrated. I got into 3D printing in 2014 and I don't think I'm being pedantic when I expect software with an option called "expert" mode to allow me to choose what angle bridging happens at. On my part much of the bridging would be more effective printed at 45deg to the part. Here are a couple pictures confirming what I'm getting. I made a zipped file of the .mf for the part.

RE: Expert Mode? Really?

What may be confusing to the OP is that fill angles are NOT relative to the OBJECT.  They are relative to the workspace, ie the bed. 

You can set all the various different types of fill angles and they will still be sliced in whatever direction you have set them even if you rotate the object.

Yes.

Not quite. You *can* set different bridging angle by object using Right click>Add settings>Infill>Bridging or Infill angle.

RE: Expert Mode? Really?

What is it today with people not fully reading posts ?  I didn't say that you couldn't set different angles per object, I simply pointed out that the angles you do set are all relative to the bed and not the objects themselves.

So set 30 degrees and the fill will be at 30 degrees.  You can set that globally via the profile or with a modifier as pointed out by Foxrun.  However if you then rotate that object the fill will still be at 30 degrees relative to the bed.  Meaning if you get the perfect angle for your part and then decide to rotate your object, your fill angle then needs to be adjusted to match your objects new rotation.

RE:

These responses are not representative of the experience I had. What you guys have shown/described is what I expect but not what my slicer has done. I set the bridging angle globally yet it did not have any effect. When the question is asked "what is it today with people not fully reading posts?" yet apparently nobody even looked at pictures (screenshots) of the actual result I was getting in Prusa Slicer. In those screenshots, in the first image you can see that bridging angle is 45deg yet the tool path for bridging is at 90deg after sliced. That result is neither 45deg relative to the bed nor 45deg relative to the part.

WTH! I tried editing my post text and was able to once then when I did it again the edit was not applied and now there is no longer an option to fing edit at all???!

Allowed to edit a post one time and thats it?! 

RE: Expert Mode? Really?

The edit window is very short.  You have to edit within a few minutes.  After that posts are locked and can not be edited.

The reading posts comment was directed at Foxrun, my apologies for not making that clearer.

Your screen caps are too zoomed in, I can't tell what angle its at relative to the bed at all.

Please attach an example project file that shows your problem.  Use File> Save Project as from within Prusa Slicer.  Then take the 3mf that is saved and ZIP it up.  A saved project includes at the settings from the currently in use profiles as well as any modifiers etc that may be in use.  Its the best way to get help as then people are slicing with exactly the same settings and can see what is happening.

RE:

In the third post, third orange clickable "link" is a zipped project file. If you clicked on that (you know like) "What is it today with people not fully reading posts ?" you'd have already seen.

Otherwise when you look at the image below the SUN on the bed (as in FLSun) is the front of the bed for reference of part orientation and bed in relation to slicer viewpoint/screenshot/image.

RE:

And yet another screenshot showing the bridging angle within the settings tree on the right of UI

Am I hallucinating or is that bridge angle (not) 90deg? Looks like 0 deg to me!

RE: Expert Mode? Really?

Again I apologise, I missed the fact the third link was a zip file, in the phone it just blended in with the other links to your pictures. 

Your problem is that no matter what angle is set in the bridging field it is not being used as your model is not using bridging as PS defines it.  Your model uses 'Bridge Infill' and NOT Bridging. 

Bridge infill is just the layer that supports top layers and is 'inside' the model so can not be seen.  Prusa Slicer treats this completely separately to Bridging which is a visible underside of a printed object surface. You have control over the angle of that via the bridging angle setting.

For the infill type of bridging you are out of luck.

Attached is a zip with an added object that uses what PS considers bridging.  You should be able to see that the bridging angle is used for that.

See https://github.com/prusa3d/PrusaSlicer/issues/11644   

RE: Expert Mode? Really?

Sorry for the third post, but edit time window 🙂  If you want control over the bridging infill angle then change to something like Orca Slicer.  It has split out those settings and has angle control over External Bridge Infill direction and Internal Bridge Infill direction.

RE:

Ok thanks I actually went over this like a year or two ago now with someone else and a different model while I was trying out the non-planar fork. I get that most people ("non-experts") don't care about this sort of functionality or lack of it. Just disappointing to see slicer developers chase the newest flashiest features instead of or before addressing things like this.

I was using Prusa Slicer pretty much only because it was the only slicer I had used that functioned with my Delta. Last night I spent some time and got Cura working with it too so I don't have to worry about this Prusa slicer nonsense.

Thanks again for hanging in there with me and trying to help if only to explain that what I expected isn't (at least currently) possible.  

RE: Expert Mode? Really?

One other thing to mention. I got automatically subscribed to updates on my posts. I don't like or usually need a reminder in my email for every reply to a single post I made. I clicked on the unsubscribe link in one of the notification emails and it directed me to the main Prusa Forum page without anything obvious to perform that action. I went to my account (My Profile and Manage Account) and I see nothing to perform an unsubscribe from emails there either.

Could you advise on that?
