I have pitting / holes on objects, i've tried to tune the flow amount, with less flow it seems there is more of pitting, and higher flow results in less BUT i have flow too high, holes come way too small, and still some pitting is happening.
It looks a little bit like moisture in filament, but this happens always on same spots on the objects, ie. not completely random.
It happens in both infill and perimeters.
No matter do i use slic3r or cura. Cura at least has 5% overlap on infill.
First i thought it's just the filament as it's been sitting around for a long time, but no matter do i use ABS or PLA, or what color, all of them do the same thing.
Higher infill seems to limit this to a degree, with high flow %, however then i get practically all solid objects
Even extremely long bridges however do work, even at low flow rates, tho they did sag as i had temps too high.
