ADT - Abstract Dog Test - Lines on surface of walls

thingiverse

Lines on surface of walls test, Abstract Dog, sort of art, if is shown on a side :) Update 03 Added a nano variant - 10 minutes print Update 02 Added a micro variant - 15 minutes print Update 01 Added a mini variant - 30 minutes print Initial post https://youtu.be/TjmVtYRaEZk I'm trying to get rid of these lines on surface of walls which seems to not depend on (so far) 1) belt tension 2) extrusion multiply (e-steps are calibrated) 3) temperature 4) speed 5) filament 6) retraction on/off 7) infill, amount, before after walls nor 8) slicer, tested in Cura and Slic3r They seems to depend on geometry so I designed a test object which feature the lines better if the light falls from above. I'll be ready to re-check some point(s) from above if you think it can cause that. If I'll find out what causes these I'll post the cure here, until then I ask for the help of community for a possible direction to investigate. You can use it to test to see if it depends on printer. Thanks!
