Problems with segmenting and deforming circle

Posted · Problems with segmenting and deforming circle

Hi there! I'm in the middle of the testing my 3d printer and I have some problem while slicing circles.

 

I fount that that Cura (?) segmented my circles, and  in some cases make it looks weird and deform on different layers. Sometimes one segment is just missed as well .

I've model this circles with 0,4mm wall thickness in Fusion 360.

 

Previous I've tried with different sizes of circles and sometimes one part of circle is segmented and other piece is now. Sometimes whole circle is made from one line.
I've also tried to model just a cylinder with no top and bottom and set the wall thicknes in Cura and it works well but have problems with overlapping objects so started setting the wall thickens in Fusion.

 

Many examples in attachments.

    Try making your wall thickness just slightly thicker. Or reduce the line width setting in Cura a smidge. There's also a setting called horizontal expansion which will artificially make your walls a little bit thicker. Pick one of those three and you should be good to go. Basically what's happening is that it's an edge case for the math involved in creating the line segments.

    Thanks!
    Horizontal expansion on 0,01 mm helps 🙂

      • 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
