First Layer extrusion multiplier? Slic3r

Hey guys, I've been looking around, and I can't find it, so it may not exist, but is there way way to increase the first layer's extrusion multiplier on Slic3r PE?
The only thing I can think of, is to raise the first layer height in the slicer, and lower the live-z on the printer.

I am having a serious issue with this, and Short of the "hack" above, I'm out of ideas. (and I'm not really eager to try that hack, as it's a BAD IDEA)
I really don't wanna gouge my PEI.

I adjust in "Print Settings" "Advanced" "Extrusion Width" "First Layer"... Not sure if this is much better though...

Sadly this won't work, as it also increases the gap between the lines. It may help a touch, but it won't "fix" it.

I hate being so cryptic on this question. lol

I'm thinking the only option would be a "post script" that increases extrusion at start of layer 1, and decreases it at the start of layer 2.

Why do you need to increase the extrusion multiplier just for the first layer? The extrusion multiplier is intended to adjust for inaccuracy between the amount of filament the printer thinks it's extruding vs. the amount it actually extrudes. That shouldn't be affected by whether you're on the first layer vs. other layers.

So what problem do you need to solve this way?

When a print surface isn't smooth and is textured, to prevent ramming my nozzle into my... *cough*textured*cough* print surface.... I don't want my nozzle 0.08mm away from it. Because Some things in this world can't be replaced. 🙂

The correct way to do this is by setting your first layer height. I generally set a first layer height of 0.2mm even if I'm printing much thinner layers otherwise.
