I have a Prusa i3 3D printer and am using Slic3r for slicing.
I've noticed that my extruder is underextruding. I've correctly set the nozzle diameter and the filament diameter and I've already tried to increment the extrusion multiplier (which is currently set to 1.1). As Slic3r suggests this is a maximum value, I'm wondering if there is something else wrong.
Does anybody a have suggestions on which settings I can look at?
