    backup all Cura settings

    in UltiMaker Cura

    Posted

    I have 2 cutomized printers, 2 customized materials, and 10+ customized profiles.

     

    I wonder what's the easiest way to backup all my Cura settings reliably.

     

    Is it keeping a copy of the folder "C:\Users\xxx\AppData\Roaming\cura\4.8\"?

     

    Thank you!

    I do not see it as offensive, but slicers are trying to be the best at slicing, not model compensation. Things like mesh modifiers do their job very well as they are designed to do. Vary the infills, wall counts, voids, etc.

     

    As I use modifier mesh more, I find more limitations.

    I am of the school of thought: Make the object the way you want it to print.

     

    You are absolutely corrrect to some extent!

     

    Yes, very often, we should create the models in the way making the printing process easier. But this is not the excuse for slicing software not to do its job that could be done better. In many cases, the slicer can do more.

    Hi @ahoeben   Thank you for sharing!

     

    But I'm sorry to say that your approach is not generally applicable. In fact you created the lower "top layers" manually. Here what I presented is only a simplified model, and you can do it by hand.

     

    If the model is a figurine or a real mechanical part, to manually creat every lower "top layers" is unaffordable.

     

    Thanks again!

    I find some .cfg files in the folder C:\Program Files\Ultimaker Cura 4.8.0\resources\quality\creality\base

     

    But all the .cfg files, including all the "global" .cfg files, contain only some modified items.

     

    Where is the full list of all the setting items stored?

     

    Thank you for some clues!

     

    ADD: I just found it here:

    In the sense that the top surface where you are pointing to is open, but the parallel plane further down is not?

    Yes. Exactly!

    No, I can not think of a way, other than setting the model to be sliced without any top layers, and forcing to print top layers for the lower top with a modifier mesh or additional geometry.

     

    Do you think that it's possible by using modifier mesh? I tried it but failed, because a modifier mesh always lead to NEW top/bottom layers in the main model.

     

    If possible, could you have a try? Thank you!

    Please let me clarify the question further.

     

    Is it possible to use Cura to slice an oversimplified model as shown in the picture while ...?

    • in the orientation as shown (don't rotate!)
    • no top-most layers (=0) only at the top (other top layers not affected)

    I wonder whether somebody tried this profile with S3 printer. It's unbelievable.

    What do you mean by your real model? 

    Without knowing the restrictions, why not construct a hollow cylinder? 

     

    Here the cylinder is only a over-simplfied example. "Real model" means for example a model having bottom/solid layers in middle heights (not the top layers and not the bottom layers).

     

    What I talked about in the original post was that:

     

    When a model is "cut" by a modifier mesh in Cura, "NEW" top/bottom layers would be added. This behavior is not appropriate. In S3D, when you print the height 0~50mm of a model of height 100mm, no top layers would be added at the "cutting plane" (at height 50mm).

    Hi @fvrmr   It works. I was not aware that the X/Y distance has such a big effect. Thank you!

     

    Sorry for another question (to simplify, I changed the support type to Normal and overhang angle to 60°)

     

    How can I remove the steps and make the support contact the model 100% at the edge?

     

    I tried to suppress it with settings below, but the steps persist:

                Support X/Y Distance = 0

                Minimum Support X/Y Distance = 0

                Support Stair Step Maxmum Slope Angle = 89°

    It seems to be magic for some Ultimaker profiles. I know that disabling "Outer Before Inner Walls" would give some help, but it's really magic.

              • Layer Height = 0.2 mm
              • Outer Wall Line Width = 0.4 mm
              • Overhang angle = 60°

    Let's consider slicing a cylinder of height = 100mm.

    •  Layer Height = 1 mm
    •  Top Layers = 1
    •  Botton Layers = 1 

     

    I want to suppress the Top Layer at height 99~100mm. But Top Layers for the cylinder must be set to 1, because my real model need it for lower range.

     

    So I create a Cutting Mesh to modify the cylinder top (99~100mm)

    • Top Layers = 0
    • Botton Layers = 0 

     

    But the Cura result is: One top layer at height 98~99mm (immediately below the cutting mesh) is printed for the cylinder.

     

    How can I suppress the Top Layer at height 99~100mm, without getting new Top Layer at height 98~99mm? (Top Layers for the cylinder must be set to 1.)

     

    Thank you for your help!

    I tend to just use the preview and look at the "speeds" color scheme. Since the outer walls are normally at the same speed, you should be in a single color. Areas where this is not the case are due to the min layer time kicked in.

     

    Sometimes the color change is not easy to judge. I doubt whether it's possible to significantly increase the contrast. This seems to be impossible. Thank you for sharing your approach!
