help me figuring out what to change

HI, guys i don't know what more i can do to improve my pla prints, there is so many parameters to change...
here are mine actually, printing temp: 190°c
i print on 3m blue scotch
i don't cool the printed part( i think it's my problem)
10mm.s-1 speed
layer height 0.16mm
nozzle 0.4mm.
i join my slicer config file for more informations.
just ask me if you need infomations i didn't gave!
Thanks a lot, for any help!

Your pictures are small. What seems to be the problem? Which printer/extruder are you using?

Have you measured and adjusted the E steps?

here a bigger one.
So according to me, the filament isn't spread correctly when the three first layer are done.
As i succeeded the thin wall print, i think that after a few layers, the part is too hot, and soft, and that's why the filament doesn't spread well.
what do you call the E steps? step per mm for the extruder in configuration.h? cause i set it, but never modified it. What could it change?

ps, i use my own design a kind of big mendel, with a buddaschnozzle

Yes, the E steps will tell you how much filament needs to be extruded. This value is not the same for everybody. Check this guide out:

Yes, you change it in the configuration.h

thanks for everything, it seems that i have either a problem or a misunderstood
if i extrude 30mm with pronterface i barely get 7mm, the 30mm seems to be 30mm of 0.4mm extruded filament and not of the 3mm one.
Asking to extrude, 10mm in pronterface, should move 10mm of filament into the hotend? or extrude 10mm of 0.4mm filament?
thanks for that, it's not clear to me

30 mm in pronterface = 30 mm of filament (3mm), I'll use your words "it should move 30mm of filament into the extruder".

Asking to extrude 10mm should move 10mm of filament into the hot end.
