If the First Layer Width is Under 100%, it will decrease the amount of filament extruded.
If the First Layer Width is Over 100%, it will increase the amount of filament extruded.
Not sure about the other two statements, but w.r.t. the above my understanding is that is NOT the case.
My understanding of the S3D's First Layer Width is the distance between adjacent infill lines. Increasing the FLW will make the adjacent infill further apart AND extrude more filament to make the lines wider - proportionally. So the nett effect is that you have the same amount of filament going into the first layer. This is NOT how Cura or Sli3r work and I think this where some misnomer/miscommunication is occurring.
Cura and Sli3r have settings for adjusting the extruded filament for the first layer - thereby adjusting the width of the lines for the first layer. ie: First Layer Width.
So "First Layer Width (Cura/Slic3r)" <> "First Layer Width (S3D)"
From all the settings I have seen in S3D, there is no setting which will adjust the amount of extruded filament for just the first layer. If there is, then please point me to it because I am tearing my hair out. At the moment I am setting my flow rate manually on my printer when I print the first layer and then manually setting back to 100% when it gets to the 2nd layer - very tedious. AND if I forget to go and dial it back to 100% I get a messy blob of a failed print.
Clearly there is a need to be able to adjust the extrusion multiplier for the first layer.
