[[Bug] "Retract before outer walls" does not work.]

Here. You can clearly see where it retracts every time it goes to the (green) inner wall E8.40884 -> E5.90884

where instead it SHOULD be retracting before the OUTER WALL. Youll notice there is no retraction step from the transition of inner wall to outer wall. Retracting before you go to the inner wall does absolutely nothing to your seam because that's not where your seam is. It's your outer wall that determines your seam, and thats where you want to retract to have perfect seams. 

To prove this, I tried setting wall line count to 1. This tricks it into behaving like the expected behavior of wha this setting was meant to do. So that way it would go from infill immediately into outer wall (no inner wall) and it creates absolutely stunning perfect seams. I honestly think whoever wrote this made a mistake and meant to have it retract right before outermost wall.

[[Bug] "Retract before outer walls" does not work.]

I found a bug where the feature to retract before the outer walls flat out does not work. There is no retraction when moving to printing the (red) outermost wall. What the programmer did wrong was that the interpreted all walls as outer wall, including the (greenl inner wall that shouldn't count. The retraction step needs to happen right before the red outer wall.

 

You can see it for yourself in the printing process. And the fix is really easy, You just have to rearrange the insertion of the retraction.

[[BUG] "Infill only" for modify overlaps NEVER works. Proposed solution here:]

Oh and if the infill only checkbox is going to be flipped on by default and appear in the options. You might as well show people the infill density option by default too. There's no point if I have to manually find infil density in the mess of options every single time

[[BUG] "Infill only" for modify overlaps NEVER works. Proposed solution here:]

Per Model Settings -> modify settings for overlap -> infill only

 

Never works, and you always have to manually set everything (outer wall, top, bottom layers) to 0 before you can get the expected result as shown in second image:

 

Here in the second img, I set the density to 3%, and that checkbox that says Infill Only is completely inconsequential. The expected behavior for having infill-only should be as seen in the second image.

 

 

 

I think I know what it's doing in the first image too. Cura interprets this support blocker object as a separate stl and tries to generate its own up/bottom/outer skins, and inserts it inside the main mode. This should honestly be off if InfIll Only is turned on. An easy fix would be to turn all 3 skin options to 0 like I have shown in the second image IF the checkbox is on.

["Extra restart distance" but for Cura, so as to eliminate blobs once extruder starts outer wall.]

Hi, so in S3D, there's this absolutely crucial setting called extra restart distance and I can't find anything equivalent to it in cura. I searched the GitHub and only found that people have attempted to put in a negative number for "Retraction Extra prime amount" in an attempt to emulate how s3d does it but I dont know if that's correct (it turns orange when you enter a negative value). How do I solve this? I'm getting some blobbing once it starts on the outer wall, and this is WITH "retraction before outer wall" turned on. It's just extruding material prematurely too quickly.
