Pillowing II
II. Top layer thickness increasing
Increasing the top layer thickness is the easiest solution. Most common softwares will enable you to do this. Check the advanced section, under the 'Bottom / Top Thickness setting'. Usual its set up fot 6 layers of material normally and up to 8 for nozzles under 0,4 mm. If your layer height is therefore set to 0.1mm then set the 'Bottom / Top Thickness setting' to 0.6mm. If the effect of pillowing still persist then increase to 0.8mm.
