Extrusion Multiplier for each Feature Type

[arshish1612]

At the moment we just have a single extrusion multiplier. Can we get this setting for each feature type? This is a setting available in Cura abut it is missing in Prusa Slicer

This would be very useful for high flow printing, for example, if infill is printed with higher volumetric flow (which means slight underextrusion) compared to perimeters. My current workaround is using Gcode substitutions:

replace:
;TYPE:Perimeter

with:
;TYPE:Perimeter\nM221 S100 ; set flow to 100%

and

replace:
;TYPE:Solid infill

with:
;TYPE:Solid infill\nM221 S110 ; set flow to 110%

etc.

But it would be easier if there were settings for this (or something like "Dynamic flow compensation" as suggested here: #10168 )

When can we get this feature? Its an absolute Must have for clean top layers. Even OrcaSlicer has it implemented for Top layer.

I currently use these substitutions. This gives me a near perfect finish.

However the problem I face is that the first layer is also labled as Solid infill. As a result of this, the 80% extrusion gets applied to the first layer also.

Is there any way to isolate the first layer from the substitutions?

You can use a post-processing script that does the substitution for all layers except the first. Search for a good script and change it to your needs.
