Flow top layer!!

[Mikeline94]

insert flow control for the top / bottom layer only. This feature is fundamental and already present in all the other slicers. It is even present in super prusaslice!

At least for the first layer this has been requested already in #6025.
The first comment describes how to get this implemented using custom gcode.

@Mikeline94 What would be the use on the top layer?
As @fe60 mentioned, you can easily do it for the bottom layer in the gcode.

I would say it is similar request to #7200.

You can already do that by using g-code substitutions, which are available since 2.4.1-beta1. Different flow for top solid layer is actually described in the changelog as an example, see https://github.com/prusa3d/PrusaSlicer/releases/tag/version_2.4.1-beta1.

An example of a quite powerful G-code modification by a reasonably complex regular expression: Increase the extrusion rate of top solid infill from the default 95 percent to 98 percent.
Find: (;TYPE:Top solid infill\n)(.*?)(;TYPE:|$)(?!Top solid infill)
Replace with: ${1}M221 S98\n${2}M221 S95\n${3}
Modifiers: regexp, single line

We are considering adding some sort of "per-feature" flow setting in the future.

I am closing this issue as a duplicate. You can continue discussion here #7200.
