Hi, thanks for your reply! Indeed, Combining Mode is what i was looking for — mostly „no skin“. I then only needed to go and set most patterns to ZigZag instead of Lines, to avoid incredible amounts of retraction. I have to admit that i didn’t quite understand what exactly the X/Y-layer-start biases, and how — but i’m experimenting around :-). Thanks for your extremely helpful reply! Best -NebuK

Hi, yeah, the initial retraction settings were a bit off the mark, but that’s not what I meant. Not saying I don’t appreciate your tips, it was helpful during tuning! What i meant is the basic behavior of Cura. Take this example: Cura will first print the outermost (red) wall, then the outermost-inner (green) wall, then travel to the innermost-inner wall (blue arrow), and continue there. During the blue-arrow, no retraction is triggered, and it oozes like hell. This is bad, since we’re on the first layer: The bottom-solid is going to be printed onto the oozed-across line which has considerable thickness. This destroys the evenness for the 2nd layer, and also the visual quality of the bottom of the part …. Also, this also happens for solid-top, where the ooze-lines then show through the roof, impacting visual quality and smoothness of the parts roof again. This is — I fear — not tuning related, is it? If there’s a setting in Cura that alters this behavior, I’d be glad to know which (maybe I’m just blind, overlooking it …). Anyhow, thanks a lot for your help so far! -NebuK

Hi everyone, I’m using Cura 2.7 to print with my marlin-based i3-style printer. However, I‘m noticing some strange retraction behavior. First, here are my retraction-related settings: I also have "Z Seam Alignment" set to random. What I’m seeing is two-fold: First, when travelling over inner parts of a print, no retraction is triggered. This might be fine for infilled layers, but for solid layers, especially on the top, this is suboptimal: The filament oozed during these travels will show through to the the outermost layer. Secondly, Even though Z-Seam is random, cura will travel to one fixed corner of the object, and do it’s layer-change-retraction there, then travel to a random corner, and re-start printing the now-new layer. Of course due to slight imperfections of re-start after retraction as well as hovering above this corner while retracting, this will make that corner ugly/blobby in Z-direction („up along the part“). Does anyone have a gut feeling which setting to look at? Or any idea how to fix? Thank, and best regards, -NebuK
