What I have noticed is that the inner volume of the block prints fine at any layer thickness (I tested from 0.04 to 0.3 layer thicknesses). As I decrease the layer thickness the quality of the outer surface/perimeter of each layer decreases. I believe the problem is that every time a new layer starts, it prints the outer perimeter of that layer extremely fast compared to when it is printing inside of that layer. This makes the
