Extrusion widths for individual features possible somehow?

Hi

I have been struggling with tuning parameters for detailed parts for a long time and I am lacking the correct tools.
One such crucial tool would be the ability to change extrusion widths for different feature types. At least the base number.
Can this be done through some way in scripting even if it isn't possible out of the standard visual UI features?

I print mostly on Bambu machines and currently the strategy is to create a "the least bad compromise" between global EW, offsets, inner perimeters and single extrusion gap fill. Changing EW for single features would help a ton.

Re: Extrusion widths for individual features possible somehow?

The perimeter extrusion width is set on the Extruder tab (this is the one users change the most). You can set the infill extrusion width on the Infill tab by changing the Infill Extrusion Width setting. The single extrusion widths will change dynamically based on the part size, but you can set the ranges for those widths on the Advanced tab.

Ok, but as I have interpreted this topic is that the infill tab only controls the actual infill as in the grid or gyroid or whatever chosen.
Is there a way to control the inner perimeters?

Context: If I choose only one perimeter the slice engine goes bananas and the result is horrible because it can not understand how to fill the very tight spaces. When I choose 2 or more perimeters the second perimeter is only fitted in a few places where there is room, and the rest of the gaps are filled by the single extrusion gapfills.

Where the slicer actually put a second perimeter it tends to be non-sufficient extrusion and gaps. This is why I want to be able to tune the second perimeter individually, either to make it fill better or widen it to force it out of the small areas the slicer would normally place them and have it replaced by single extrusion gapfills.

The Extruder tab is where you set the width for all perimeters. You can't use a separate width for inner vs outer perimeters.

Single extrusion fill and gap fill are 2 options which can fill varying thin gaps in the parts, so you could give both of those a try. There's an article talking about the various settings here:
