Posted · Weird defect on one side of my benchy

Hey guys, i just printed a benchy to test my printer and  i got this weird line on only one side of the hull... i reprinted another one and the defect is exactly the same.. just like if the STL was made with that strange line.. not sure what could cause this.. I get random lines like this occasionally on some of my print and can't find the reason

 

Using Cura 4.11 with a stock Ender 3v2

 

Thanks!

    It is the Z seam that marks where the outer wall extrusion starts and ends.  You can move it, you can try to hide it, but there is always a Z seam.  If your graphics card is up to it then the Z seam is a white line down the preview.

    To the right of the settings search box is the settings visibility control.  Click on it and set visibility to "All".

    At the bottom of the "Wall" settings you will see Z seam alignment.  Try User Specified and then pick a location that is a corner of the boat's transom and then chose Smart Hiding.  Set the Outer Wall Wipe Distance to .1. 

    For round objects I find it best to leave it in a line rather than using random which leaves (what looks like) little blobs all over.

    Thanks Greg for the answer .. really appreciated

     

    When i slice the STL and i go to preview, i don't see any white line on it.. i don't see either the play button that can simulate the print .. i have the layer scroll bar so i can see each of them individually but  that's it

     

    As for the Z seam alignment setting it was already set at User Specified but can't see where 

    the location is and it was already set at smart hiding..

     

    So the only thing i've changed is the outer wall wipe distance to .1 and reprinted the benchy but result was the same as my 2 others

     

    Thx again for your help.

    Cura currently requires OpenGL 4.1 to use the full fancy preview.  If you just have 2D flat lines instead of 3D tubes in the preview then you are in Compatibility mode.  You might be able to change it using the Preferences | Viewport Behavior | Force Compatibility Mode option.  You might have to update your video drivers though.  My laptop is beyond help and I'm stuck with the 2D version.

    In the 2D view - if you turn on the "Travels" option in the Linetypes dialog you should be able to pick out the Z seam location as your wipe travel moves should be in a vertical line.

    I use Ahoeben's GUI plugin for the interface so mine might look a bit different than yours.

      • 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.
