Hi!

 

Hello guys, happy to join the community!

 

Have you ever encountered problem with added elements in cura in starts layer? I have attached how the elements look like in cura and after printing. The stl is generated from Autodesk Inventor - for sure there is no error in stl.

 

Thanks for your help!

    Welcome from wet Florida.

    If you are referring to the white line - it is the Z seam.  it marks the beginning and end of the outer wall extrusion.

    There is always a Z seam.  Cura has options to move it around and it can be hidden in corners on a part with corners.  On a round part there are really just two options.  The seam can be "random" (which results in little blobs all-around the part) or you can designate a "location" in which case the Z seam is a line (but is easier to sand off).  Because your part is threaded you would need to make a choice.

    A triangle file will remove a "line" very easily from male threads.  "Random" doesn't require any post-process of the print but will make the threads slightly larger and may cause issues with the fit between male and female threads.

    You can make adjustments to things like outer wall wipe distance or try Coasting (which can have secondary effects) to alter the size of the bump, but there is always a Z seam.  Previous versions of Cura didn't highlight it.

    Great explanation! Thank you! 

     

    P.S

    My experience of Florida was quite opposite - dry and hot!

    "My experience of Florida was quite opposite - dry and hot!"

     

    Missed hurricane Irma did you?  48in / 122cm of rain in 48 hours.  I admit it was a hot rain though.  An interesting side note was that most of it was moving sideways as if gravity was too soaked to work well.

      • 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.
