Also some colors show up tiny defects more than other colors. A white filament will hide most of that nicely. Or primer paint.
Try unchecking "combing". This will change things quite a bit. But you still might not like the results. Also if you want really good quality do this:
1) Make ALL printing speeds 25mm/sec (and movement speed at least 150mm/sec).
2) Set temperature to 210 or lower
3) layer height .1mm.
This might eliminate those marks. Or possibly not. But in general printing slower helps because you get best results when the extruder never slows down or speeds up and printing at 25mm/sec allows that to happen for the most part.
Hmm -- I'll fiddle with those ideas. I turned combing on a while back and haven't ever turned it back off; things seemed so much better with. On the other parameters:
I ran that at 0.15 layer height; 0.10 takes soooo long.
My speeds were
/*
travel_speed = 150
bottom_layer_speed = 20
infill_speed = 100
solidarea_speed = 40
inset0_speed = 50
insetx_speed = 70
*/
...and temperature 200 descending to 190 above layer 4.
Retract while combing for Cura fixes that thinks for me.
/*
retraction_speed = 80
retraction_amount = 4.5
retraction_dual_amount = 16.5
retraction_min_travel = 1.5
retraction_combing = All
retraction_minimal_extrusion = 0.02
retraction_hop = 0.1
*/
Be patient. Set them all to 25mm/sec - just for once to see how it looks.
Everytime you speed up you get underextrusion for a portion of a second. Everytime you slow down you get overextrusion very briefly. This affects quality. Just try it ALL at 25mm/sec. Just so you know.
Except travel speed! Keep that at 150mm/sec. Or faster.
