Please, see attached picture of the part I'm trying to print. I've also added the stl file.
My problem is simple. I want the two thin walls to be 0,4mm thick (also verified in the solid model from wich I've made the stl). My printer prints it 0,6mm thick.
Extrusion width 0,4mm
Multiplier 1,02 (ABS hot chamber) - yes, i've done a previous calibration printing a single walled box and it prints 0,4mm walls.
Top and bottom layers 2
Perimeters 2 (i've also tried 1)
It is obvious that those walls are Outer perimeters, so why is my machine extruding 0,6mm thick walls?
I've also tried Slic3r, but it uses a diferent outer perimeter deposition method (discontinuous) wich I didn't like and gave bad finishing to the part. But it respects the 0,4mm wall...
I've also tried printing with a extrusion width of 0,25mm just to see how it would react and it prints the same 0,6mm thick walls
Any help would be apreciated. I'm using S3D 3.0.2
