gm2gabriel is on a distinguished road

I am having bad layer coverage as seen on attached screenshots.

I consider the snapping good, but have no clue on how to improve the layer process, those are my setting at the moment:

expansionRatio 1.2;
finalLayerThickness 0.5;
minThickness 0.1;
nGrow 0;
featureAngle 180;
slipFeatureAngle 30;
nRelaxIter 5;
nSmoothSurfaceNormals 1;
nSmoothNormals 3;
nSmoothThickness 10;
maxFaceThicknessRatio 0.5;
maxThicknessToMedialRatio 0.3;
minMedianAxisAngle 90;
nBufferCellsNoExtrude 0;
nLayerIter 70;
nRelaxedIter 30;

I did several trials changing featureAngle and slipFeatureAngle, but no visible change. Could anyone help me, please?

*Edit: thanks to this publication I found help and solved the problem!
