    The "bug" comes from your settings. With a normal configuration there is no problem to use these file as a Custom support.

    Thanks!!
    When I read earlier your response I missed the "Support Placement: Everywhere". I changed it and it works. Wouldn't have guessed this parameter is relevant.

    I think you are asking for a new feature: "create supports that support the model but fit within this mesh".  That feature doesn't exist yet in Cura.

    With the help of CuQ it seems there is such an option after all (-: Just not where I expected it to be.

    @adi_s - I disagree - I don't think you found any bugs yet.  Just maybe the language used in the gui is confusing.  Maybe you found a bug or two but if so then I don't understand.

    If I save a 3mf file with this:

    And when I reload it, is seems like this:

    Isn't this a bug?

    support spacing is controlled in CAD and/or meshmixer.  not cura.  If cura generates it's own support with it's own algorithms - then yes you turn on the support features and you can set things like support gaps in x,y,z.

     

    But the feature you were using was intended to *remove* support from areas other than the shape.  You can add shapes to cura that can either block support.  Or exclude support outside the volume.  but since you are designing support in other software you need to disable all cura support features including the "per object" support features.

     

    Thanks, As far as I tested Cura adds z space not just with it's own supports but also when creating a supports with the plugins "Custom supports" and "Cylindric Custom support" or importing a supports created elsewhere, it does so with any object with "mesh type: print as support". But all of these supports have the same problem, Cura adds unnecessary supports underneath it, even when supports is disabled.

    It seems as a bug in Cura.

     

    How to report the 2 bugs I encountered in Cura?

     

    I need a slicer that can handle custom tilted supports.

    I started today testing supports in Prusa slicer, hope it would be easier there.

    Yes. These models were designed a couple of years ago for single-nozzle printers, and older slicers. So they are all printed with the exact same settings. Sometimes I provide gaps to make removal easier, so that parts are only kept in place by strings, not modeled connections.

    .....

     

    Thanks for the detailed answer!

    I've just bought the printer 2 months ago and I'm studying the methods, materials and software. According to my trials the automatic supports in Cura are probably not good enough for me so I'm testing other support methods. I don't plan to print the model in this post, did it just to clarify the problem I encountered with Cura.

    Will probably do as you suggested, model the supports in 3D modeling sw and not count on the slicers.

  5. The tilted cylinder was defined as support. I want it to be printed as support and to not add any more supports.

    (I know it can't be printed well, modeled it just to demonstrate the problem I encountered).

     

    Is this what "drop down support mesh" intend to do?

    I'm using Cura 4.8, is it better in previous versions?

     

    when it is off Cura slice only the part above the cylinder base.

    When it is on, Cura adds unnecessary support underneath the cylinder

    The problem with your meshmixer supports is that by default Cura "projects" the top of support meshes to the buildplate. Try adding the "Drop Down Support Mesh" setting to the meshmixer supports (in the Per Model Settings) and unchecking it.

    Thanks, have just tried it and Cura parsed only the bottom of the support object.

    Please confirm that you just have one extruder.  If you want to print the support tree with the second extruder you want to assign that model to extruder 2.

    I have one extruder and rechecked it in the settings.

    So don't tell cura to "print as support".  Instead just tell it to print normal as shown below.  Also for some reason the 3mf file doesn't have the "tree shaped" support but somehow it got simplified into a hull shape.

     

     

    I sent the wrong file, it was another test.

    If I print the tree as a regular object and not as a support, how do I get the support Z distance?

     

     

     

  8. It seems the problem with the 3mf files that I attached previously was caused by a bug in Cura.

    It can be replicated -

    1. Import "sup test1-mesh mixer.stl"

    2. Extensions>Mesh tools>split model

    3. Select the tree and turn it into "Mesh type print as support".

    4. Save the 3mf file.

    5. Load the 3mf file - The loaded objects aren't in the same position as before, the support isn't under the object.

    bug - tree support test1-mesh mixer.3mf sup test1-mesh mixer.stl

  9. Hi all,

    Is it possible to add customized non vertical supports?

    When importing tree supports created by Meshmixer and selecting "Mesh type: Print as support", or  rotating a support created with the plugins "custom support" or "cylindric custom support" I'm getting in Cura unnecessary supports underneath it.

    Disabling a support, or choosing overhang angle:90 doesn't help.

    I would appreciate any help.
