Can anyone tell me what setting within Cura 4.12.0-BETA  stops any travel across open voids in a model no mater what size of holes.
In this image, the object is 30mm OD and ~18mm ID

    When cura keeps the nozzle within the print to get to a new spot, that's called "combing".  Versus a retraction move like shown above where it retracts the filament and moves directly to the new spot.  You want combing.


    Combing is a feature going back at least to version 15.x (from 2015).  It's currently under "combing mode".  You can set it to "all" or I recommend "not in skin".  


    In addition, check out "max combing distance with no retract".  I'm not sure but if you set this to for example 1mm, it may switch out of combing mode for those movements.  Although hopefully not.  But consider experimenting with this as well.  


    In addition note that those light blue lines inside your part are "retraction moves" and the darker blue moves (hidden as they are in internal layers) are non-retracting moves.


    It could be that you need to tweak your settings.  I usually can't see any stringing on most of my parts.  but it depends on a lot of things whether you get strings or not.

      • 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
