[bug] huge overextrusion when skirt is multilayer #2307
consider the situation: I'm printing a tiny object. I surround it by a distant brim to increase layer printing time (to fight problems with cooling).
first_layer_extrusion_width = 0.4
first_layer_height = 0.14
skirt_distance = 20
I expected the skirt to be 0.66 mm thick. But it looks like Slic3r uses first layer extrusion width for all layers of skirt. Well, OK... So the skirt is a 0.4*3=1.2 mm thick shell of a 42mm dia 10mm high cylinder, which corresponds to a filament volume of ~1700 cm3. The model is tiny, its volume is negligible... But the g-code consumes:
My guess for the cause of the bug:
BTW, I want the non-first layers of skirt to the default extrusion width, not the first layer extrusion width.
A workaround: manually create the skirt in the .stl file.
Slic3r v1.2.0 on Windows 8.1 64-bit
