Brim not complete


Recommended Posts

Posted · Brim not complete

Hi Folks,

suddenly I've a Brim related problem. It isn't big enough anymore. Where did I make a mistake in the settings?

Cura V13.06.4

No support

Brim Yes

Fill 100%

Bottom/to and wall thickness 1.28

layer 0.16

Look in the gallery, album: Cura troubleshooting for pic's

I can't put them in this topic somehow?

    Wow, you're fast:-)

    strange, but you're probably right. If I choose to cut off the object 0.2mm, then the brim is formed. I used the "lay flat button" and the drawing is placed on it's origin on a top plane in SW.

    I can't find the error in the original drawing for now.

    Thanks, it will save the problem for now, but the measurements are haywire:-(

    Update( hopefully with correct info:-)


    Programs used:


    Solid Works Premium 2011, no extra settings when saving as *.stl, saving all bodies, if asked.




    Cura 13.06.4, changed settings:




    Layer hight








    Shell thickness
















    Fill density












    Touching buildplate




    Platform at
















    Infill overlap











    Just as this topic starts, the problem persists, however random. It’s annoying because you have to wait until the first layers are complete, because it isn’t always possible to check in Cura.




    · - Cura sometimes crashes if trying to look at layerbuilding


    · - First layers look fine in Cura’s layerbuilding, printing result isn’t always ok.


    · - Large prints seem to be finished, but aren’t, Cura crashes.




    · I’ve to turn around my objects always. I like to draw at the top plane in SW. Cura places the object on its side. If I choose the correct circle, a number (degrees of rotation) appears. One could always rely on the 90º when putting down the object. But it isn’t always possible to turn around until excactly 90º but you have to choose between 89º and 104º. If then respectively Lay Flat is choosen, the object turns around, rather than laying flat. If one chooses to turn around a little more than 45º it lays flat by itself. If the orientation is at odds with the buildplate, there is never a problem. If it is not, randomly the object turns around instead of lay flat.


    It seems to be the happening with complex designs mostly,( a lot of curves for instance)


    I’ve made some movies. The first one is how it should be,




    the 2nd and The 3rd shows the 89º issue with another object also.






    After clicking ”lay flat” you’ll see it seems the object turns around a degree rather than flipping. Next movie shows the layers view mode.




    Everything looks good. The picture however:




    shows the aborted print, it is clear the brim and first layer is produced for approx. 50%, the bottom side is printed in the air.


    Preview with different outcome, both not printed correctly:




    When trying to reproduce the faulty procedure, I’d to try for some 20 times before it happened again. I can’t find a pattern in it. Sometimes it happens, the objects are being replaced after multiplying in a strange order. (not perpendicular) In the case that happens, there is always disorder in the first layers. It doesn’t matter if you restart Cura either way. (for good or for worse)


    I’m especially curious, if there are more designers drawing their own objects, who are experiencing the same problem. I’ve never seen this problem when downloading stuff from thingyverse. But most off these people don’t draw with SW for as long I can see.


    I tried Daid’s suggestion by cutting of the first layers with the “sink into the bottom”- feature and it helps making your way around the problem, but it sucks for measurements of course.




    PS: I wrote this text in Word en copy pasted it, but that seems not to be working very well, sorry:-(

    (Back after 2 weeks vacation)


    I think this issue is related to the lay-flat algorithm, which isn't perfect right now. But I currently have no plan to improve this. Sorry...

      • 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
