I have a part that i need to print for a project i am working on and i am just looking for some advice.

The part i have drawn up in inventor is round but when i put it into Cura it gives me a helical shape, i played around with settings to try and get it round but have not succeeded can anyone give me some advice or steps to follow to fix this?

    It has nothing to do with Cura, you have to look in your CAD application and look if you can set to use more polygons for the export.

     

    Even if the object looks round, it is made from a lot of polygons and when exporting with "rough" settings, this is the result in Cura.

    RSA Drue did this solve your helical to round problem?  I am experiencing the same thing.  If it worked what exactly did you have to do?  I see that the default setting is the Brep and there are options for high, medium low and custom under the STL save as options in the surface resolutions category.  Which did you use and what setting did you slide the slider to under normal deviation?  Thanks

    As said before, it are the STL-export settings that you need to adjust. An STL-file only consists of triangles, thus with straight edges. It has no curves. So all curves need to be aproximated by lots of small triangles.

     

    If you would be using DesignSpark Mechanical as CAD-program, set the options for STL-export to "Fine". This will create more polygons and give a smoother shape.

     

    If they would be on "coarse", you would get this sort of crude shapes, due to not enough triangles.

     

    Don't set the export resolution higher than you need. If you set it extremely fine, it causes very huge STL-files with zillions of triangles.

    use the IPT plugin from the marketplace and it stays round no adjusting of settings needed

      • UltiMaker Cura 5.3 stable released

        UltiMaker Cura 5.3 stable released

        ArunC posted a topic in Ultimaker Cura,

        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

        Here it is. The new UltiMaker S7

        MariMakes posted a topic in Official news,

        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 Alpha 🎄 Tree Support Spotlight 🎄

        Cura Alpha With New Tree Support 🎄

        MariMakes posted a topic in Ultimaker Cura,

        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.
