ADT - Abstract Dog Test - Lines on surface of walls

thingiverse

Lines on surface of walls test, Abstract Dog, sort of art, if 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 eliminate these lines on surface of walls, which seem not to be influenced by the following factors 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 8. Slicer, tested in Cura and Slic3r They seem to be dependent on geometry, so I designed a test object that features the lines better when light falls from above. I'll re-check some of these points if you think they could cause this issue. If I find out what causes it, I'll post the solution here. Until then, I ask for your help in finding a direction to investigate. You can use it to test whether the problem depends on the printer.
