I am sorry, I saw something like this posted a few times but just couldn't find a solution. Some places also lead me to think that this might be a bug? It used to work in the previous versions at least.

I cannot manage to cut holes in prints using added volumes in Cura.
Specifically - I cannot manage to get rid of the walls and top/bottom layers inside the intersection of the two volumes.
I just want to make a part of the print either a hole or infill only with no top/bottom.

    Hey @Filipino82,


    Welcome to the Ultimaker Community 🎉


    I haven't seen any reports of the mesh modifiers not working in the latest version of Cura... 

    So I think we might be able to help you solve it. 


    Do you have a project file for us? It contains the printer and settings we need for troubleshooting. 
    To save a project file go to File -> Save project.

    Here it is, with another model. Let's say I just want to do the basic task of this cube acting as negative volume. Or as infill only (no walls or top/bottom). It must be some settings being wrong.. although it doesn't even work in default profiles so I came here. 
    In this configuration as in the screenshot, it literally just prints the duck whole, doesnt care about any overlaps.

    You have the blocker set as an "Infill Mesh".

    Here the left model is from your project (I altered the Infill Density to highlight it's effect).  I have altered the right model so the blocker is a "Cutting Mesh".  The Cutting Mesh settings are No Walls, No Tops, No Bottoms, and Infill Density = 0.


    You can see that the right model has walls and floors in the cut-away section.  Those are settings of the model.  If you wanted to do something like have no walls in that area (so the infill is exposed) that can't really be done.  



    So your block in the phone protector project needs to be changed to a Cutting Mesh.

    Oooh it works! I swear I thought I had tried what you told me before as well.. well, I probably haven't. Oh well, it works now, perfect.
    The last thing you said though - to expose the infill, it can actually be done, look. Exactly what I wanted. I wanted to make this mesh panel. I'm glad I can stay in Cura for this, started thinking that only Prusa can do it. Nice.
    Thank you so much, it's a lot of support and pretty quick one too, didn't expect it 😄 Awesome. Have a nice day.

    Yes, you can do it that way.  What you see there is the blocker infill.  There are walls around that area.

    This is with the infill line-type turned off:



    This is with the infill line-type turned on.  You see the infill of the bird is not exposed, just the blocker infill.  There is no true hole into the interior of the bird.  This bird has enough problems without adding more holes.

      • 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
