I think my extrusion multiplier may be too low. For instance, on top layers, in the larger areas I can see the crosshatching nature of the previous layer through the top layer (it's not drastic, but enough that I believe it is wrong). However, I arrived at the extrusion multiplier due to measurements I took of the single line walls of my test box prints. I'd rather have not-perfect thicknesses of single line walls and have completely filled solid layers than the alternative. Should I be upping my extrusion multiplier? Is there some other parameter that could be affecting this? I noticed it on my first print in a while using 0.3mm layer height, and I believe this is also the reason that on even slight overhangs I occasionally get a thread that does not attach (even starting inside-out). On long straights I just think I'm not extruding enough and that's why I can see to the previous layer, and why outer perimeter rings on overhangs may not be attaching properly in some cases.
Any help is much appreciated!
