I updated to the latest software and firm ware and now the internal parts of my print and not printing or showing up on the preview. Any ideas what's going on?

in the current stl file it shows the holes in the the part, but after slicing and and going thru the preview process they are gone...

    This sounds like a Cura question so I moved this topic there.

     

    It's probably a problem with your model but to be sure, please post the entire project which will include your model and your profile and settings and so on.

     

    In Cura, do "file" "save project as" and then post that resulting file please.

    there is not "save project as" only "save project"... Not sure why I don't get that option. I may have to delete and reinstall, looks like the 4.12.1 release may not be a good one... lol

    Thank you taking the time to respond; I uninstalled / installed the software a couple more times and then I installed it with every driver that was not checked as the default and it seems to be working now. Not sure if that helped it or not but now I am printing again. 

     

    Again thanks!

     

    Sincerely

    Tim

    How about the infamous "Remove All Holes"?  It has it's uses...just not very often.

    @timcnc1 - sorry I don't know exactly what it says.  "save project"  "save project as".  Something like that.  They may have changed it a year ago and I still probably would have it backwards.

     

    Please save the project and post that file here.

    I have a similar problem. I have worked on it longtimes but without result. Cura is unable to print

    internal parts ! Why ? I join two simplified examples in cura and blend format. Will be very happy to find

    an explanation for this problem. It stopped my projects. Not manifold, not "hole" , not many other don't work.

    Problem for specialist of cura or blender ?

    For the most part Cura deals with "meshes".  Those are three dimensional volumes completely surrounded by a mesh made up of triangles.  No gaps in the mesh means the interior volume is "watertight".  If there is an open seam, then it isn't watertight.  It has a leak.  When there is a leak Cura can't tell what is inside from what is outside and so slices either fail or come out weird.

    Two of your three models are made up of surfaces so they are not "meshes".  They have no thickness and so they don't have any volume.  This is kind of typical of airplane parts.

    In the Mesh Fixes section is a setting for Surface Mode.  It has three options: "Normal", "Surface", and "Both".  The screenshot below shows your models.  Cura adds the polka-dot pattern to models that are in error as far as Volume and Water Tightness go.

    Here is a "Normal" slice.

    The walls that extend above the cube didn't slice because they have no Volume.

    The one wing has a gap because surfaces are facing the wrong way.  That is a problem from Blender and you can go into Blender and flip those "normals" so the inside faces inside.

    The solid wing model sliced as we would expect for any watertight mesh.

    Here they are sliced in "Surface" mode.  The cube is hollow.  Those upper surfaces are present.

    The internal ribs of the one wing are present.

    The second wing has no internal structure because it was modeled "solid through and through".

    I would guess that "Surface" is the setting option you need to enable.

    Here they are sliced with "Both" turned on.  This result could be changed by altering other settings in Cura (like the wall count, top bottom layer count, and infill density).  In this case you would end up with models that look like what was achieved using "Surface" EXCEPT for the surfaces that rise above the cube as they still have no volume.  I think the trailing edge of the one wing sliced as it did because of the flipped normals.  Regardless of how you decide to go - flipped normals always need to be fixed.

      • 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
