I am printing guitar pickup bobbins on the Normal Profile in Cura using ABS,  I get this surface;

As you can see the walls look great, the zig zag infill (100% on the next one) still shows up.  

The Ironing pattern feature in Cura are Concentric or Zig Zag.. Neither are gonna be as good as that wall.

 

Is there a way to just iron the surface from the inside out, disregarding the walls etc, just as if it was sanded?  As you can see, the walls appear this way already..

    You might try reducing the "infill overlap percentage".  You might not need any infill overlap and it seems it may be causing overextrusion bumps where the infill hits the outer wall.

     

    Also play with "extra skin wall count".  Set that to a large number like 100.  Notice what it does to your top layer in preview mode.

    Oops - yeah skin.  "skin" is cura's term for top and bottom layers.

     

    What did you think of the other skin setting?  wall count?

    Adjusting the walls had no effect since the pole piece holes end up hitting the outer walls in the middle of the print..  There must be some kind of surface sheen setting, something that can ignore an objects holes or some kind of detection that can level it out at the top

    This is what happened with these settings, 0% overlap %

    1) Did you try this?  Look what it does in PREVIEW mode to see what I'm talking about.

     

    2) Also did you play with the ironing settings?  I just assumed from the start that you tried a few different ironing settings but now maybe I'm thinking you just happened to mention a feature without realizing it?

    Also, here are all my Shell settings, It looks like I don't have a top layer, what does this really mean?

    What?  That should mean you have only infill on the top layer.  That doesn't sound right.  Change that from 0 to default and try "extra skin wall count" and you should see very different results in PREVIEW.   Not sure if that is what you were asking for.

      • 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.
         
         
        So what’s new?
        The obvious change is the S7’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.
         
        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 don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
         
        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.
         

         
        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  
        Curious to see the S7 in action?
        We’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 5.3.0-Alpha 🎄 Tree Support Spotlight 🎄
        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
         
        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.
