Hi my first point is that IMHO using 0.6 solid layer height when using .100 layers is probably not enough. I get the feeling, from my experience but NOT scientifically corroborated that the thinner the layer height the more solid layer depth required. I.E. if you are OK with .6mm when using .200 layers (ie 3 layers) the using 0.6 when using .100 layers (6 layers) is not enough.
If I were printing with .100 layers I would use a top layer depth of at least .8mmand be prepared to go higher. My general rule also is that the higher the infill density the less solid top layers required (and of course vice versa). I also suspect print speed will impact i.e. the slower you go the better those thin solid layers will lay down over the infill.

What level of fan are you using? Is the fan used on the calibration mm3/sec cup?
Are the belts tight? Have you lubricated the rods?
Could be that the fan is over cooling things including the nozzle during your prints particularly if the fan isn't used on the cup. Also with the cup, since the harder part is printed further up, even if the fan is on, it might not "backwash" into the nozzle like it would closer to the bed where the easier part is printed. The easier part might be less affected by the backwash.
Might be slightly loose belts or friction on the rods preventing the nozzle from precisely positioning during the layer fill.
