[ 2.6-alpha5 ] Provide a way to disable the Vertical Shell thickness completely

Description of the bug

Now vertical shell thickness is on by default and can not be turned off.

Project file & How to reproduce

Have the checkbox to control the vertical shell thickness solid infill back

"The old "Ensure vertical shell thickness" parameter used to switch between the upstream Slic3r and Slic3r Prusa Edition algorithms to ensure vertical wall thickness. The new algorithm implemented in PrusaSlicer 2.6.0-alpha5 is significantly better than either of the two old algorithms; thus, the switch "Ensure vertical shell thickness" was removed."

Yes, but what if I don't want to have those extra solid infills added in the slice?
Basically I just want an option to turn that on/off

[sarusani]

There was never an option to turn them off. The old box just switched between two different algorithms to calculate them. This is no longer needed since the new algorithm replaces both of them.

I agree with you, regardless of what ticking the radio button did in the past, the result\affect was it removed many areas of ensure vertical shell thickness. while there are workarounds that can help with this, it's proven very inconvenient to have to do compared to just being able to turn them off. There should be a button to remove them when unwanted. I would also say in this same paragraph that I'd like to have the control to switch back to the older bridging method, and seams from 2.4.2 when I need to.

I don't understand why it has to be one way or the other, why can't we have both. Now we have "ensure vertical shell" that we have to jump through hoops to get rid of if we don't want/need it, Internal bridging that you can't control if/when we need to, and Seams that won't do anything we want them to. How are these improvements? when all your doing is taking the control from us and then saying to us "oh what did you need that for?"

I also agree that we should be able to completely turn off the "ensure vertical shell thickness", whatever it is called and whatever algorithm is used. There should simply be an option to use none (with a proper tooltip explaining why it's usually needed).

And also, on the other hand, how it is decided what is "better"? If it's only based on reports how the old algorithm doesn't work correctly, it's easy to miss that many people might be using it and simply not having a reason to complain because it works as they want it to work. Of course things should be changed and improved, but I agree with @Snuff1eupagus that we should have a choice.

An idea: if something becomes obsolete and is being replaced with a new feature/algorithm, don't remove it for some time, but instead actively ask users at installation of a new version to give feedback if that should really be removed or not. Users would then have enough time (at least until the next release) to test both old and the new algorithms and compare, then based on user feedback, decide if there is still a reason to keep the old one or if nobody cares and it should definitely be removed.

I also agree, we need a way to disable this entirely.
I will change the issue title to reflect this accordingly.

I can't seem to find a way to do this in 2.6 - not sure why this issue was closed. I cannot figure out how to get rid of this extra infill. It literally doubles print time when compared to 2.5.

This issue is closed because another one is open: #10102
