New to 3D printing - CURA prints uneven curved walls - I'm out of options

Posted · New to 3D printing - CURA prints uneven curved walls - I'm out of options

Hey there, fellow 3d printing kids.Ā šŸ˜„
First time 3D printing forum lurker, first time poster here.Ā 
I hope I'm in the right place seeking help, and I hope that I am posting in the right category. If not, I apologize.

Ā 

Here's the thing. About 3-4weeks ago I purchased my first 3D printer, da Vinci Jr. 1.0 Pro. Got it without any deep research. Just looked up what's available near me and got one. There are no critical issues with this printer other than, after 4weeks of experience, their XYZprint slicer has some troubling limitations which translate in poor print details that bother me. The printer prints itself in a quite nice detail, but the slicer is what makes me already think about my next 3D printer.

Ā 

When I looked for solutions I discoveredĀ Ultimaker Cura 5.0.0, which I like from the perspective of UI and the amount of settings, but I am having problems with my prints that are not present on XYZprint slicer. That's why I'm here seeking for help.Ā 
I tried dozens of settings, even changing settings in small increments. No results.

Initially this is what bothered me on XYZprint slicer. I do not know why, but their slicer translates those corners as infill, which translates as ugly corners with blobs.

Ā 

That's why I triedĀ Ultimaker Cura 5.0.0, and it slices perfectly:

Ā 

However, after finding the best settings for CURA to prevent the most common 3d printing problems I am stuck with one problem that I cannot solve, and which is not present on XYZprint slicer.
Cura is printing curved walls in an uneven manner.
Look, here's how it looks on XYZprint. Even from start to end:Ā

And here's how it looks on CURA:
It starts out well for about 1/4 of the circle-

Ā 

But then it is doing this all around 'till it reaches the seam:

I have no clue what's causing it. I printed out around 20 of these circles with different settings. Nothing. Temerature. Speed. Retraction. Other settings. Small incremental changes. No result.
What am I looking at? Why does Cura print so?

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        Ā 
        Ā 
        So whatā€™s new?
        The obvious change is the S7ā€™s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        Ā 
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also donā€™t recommend using or adhesion structures for UltiMaker materials (except PC, because...itā€™s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly ā€“ even with one hand.
        Ā 
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.
        Ā 

        Ā 
        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more Ā 
        Curious to see the S7 in action?
        Weā€™re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha šŸŽ„ Tree Support Spotlight šŸŽ„
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        Ā 
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports. Ā
