Weird defect on one side of my benchy


Recommended Posts

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

    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.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
