Thanks. I mean inner wall generation (yellow/green color, the path taken between outer walls).

I tried your development version of Cura, it seems to treat inner walls differently, a bit better, in my opinion. Although it generates "blobs" and seemingly random travels sometimes, it could be fixed by a some negative horizontal expansion value - 3-lines wide walls are printed in outer-to-inner order but this doesn't destroy overhangs on my other models, unlike swapping the order with a checkbox. Could you please tell me in what files/functions these changes are? Just for an educational purposes 🙂 Thank you The "weird" travels: After "horizontal expansion" adjustment:

If i disable compensation, i get an extra circle again. And this extra circle is far from 100% of flow, such low that I thought it is a travel 🤨 That's why i didn't even tried to change Minimum Wall Flow, i just disabled overlap compensation without any success. It is a bit counterintuitive to me: - if it is Disabled, there will be an extra circle with extra low flow rate - if it is Enabled (default value) and Minimum Wall Flow is set to 0 (default value), there will be an extra circle with extra low flow rate, same if it was Disabled Is it a bug or a feature?

Minimum Wall Flow is exactly what i needed - extra circles removed. Thanks, dude! P.S. Wondering why this option isn't active if "Compensate Wall Overlaps" is unchecked?

I checked a G-CODE, and it seems like Cura tries to extrude less plastic than my printer is capable to. For example: G1 X120.635 Y115.546 E641.66235 G1 X120.774 Y115.333 E641.66255 G1 X120.994 Y114.994 E641.66282 G1 X121.114 Y114.794 E641.66298 G1 X121.332 Y114.429 E641.66328 As for my printer, a single step extrudes 1/410 = 0.00294(mm) of filament, but the G-CODE in this "extra circle" attempts to extrude much less than even a single step. The extruder wheel stands still, but, due to plastic viscosity, it drags plastic out of nozzle. At the next, "normal" perimeter, it lacks plastic and there is an underextrusion. Am i correct? Is it possible to filter out such extrusion attempts? Thank you in advance!

Hi, I'm using Cura 4.2.1 and I have issues with resulting print quality. Cura generates an "extra circle" between outermost and innermost perimeter in addition to infill, which seems to be unnecessary. This extra circle has severe effect to the print quality, as it seems to drag plastic from nozzle - the outermost layers are suffering from underextrusion. The "other" slicer didn't generated any extra circles, the model looks pretty good. I tried a lot of options: travel optimization, wall order optimization, different combing modes and retraction / z-hop settings, different temperatures, acceleration and speed values. Is it possible to eliminate this "extra circle"? I really like Cura, but sometimes it does really weird things and the resulting model looks bad 😞 The results (left 3 parts are sliced with Cura with different settings and the rightmost is other slicer, same plastic, model, speed and temperatures): Attaching a model and other stuff, check at 25+ layer (0.2 layer height): cura issues.zip
