Brim bug


Recommended Posts

The Brim works fine in general but it clearly fails on this simple cone-shaped object as can be seen in the picture. It looks like Cura calculated the brim based on the largest diameter, not the bottom diameter. I am also curious why the strange shape of the brim on a cylindrical object.

By the way, what a pain to add a picture on this forum!

    I have supports on the inside, not outside.

    Other items with internal support print correctly but they do not have an overhang.

    It is an easy problem to troubleshot since no printing is necessary- it can be seen in Cura's layer mode.

    You are correct, I just tested it and turning off the support I get a properly touching brim that is also round. Turning on the support the result is as in the the picture.

    , disable brim and change the skirt settings (change the distance and the amount of lines to 10 or so).


    Damn! I wish I tried that ages ago! In fact I now remember reading about this trick but I could have used it a few weeks ago.

    I've made a minor adjustment to how the brim is looking at support, possibly fixing the above problem. You can test this with the latest RC at:

      • 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
