    Much of Cura is implemented as a plugin, and it often helps to see what is already there and how it works. What you want to do sounds fairly similar to the Digital Library plugin that ships with Cura. The source for that plugin is available here: https://github.com/Ultimaker/Cura/tree/master/plugins/DigitalLibrary

    Cura reserves space around the model to be able to print the brim or skirt you have selected and other things. Here's an elaborate article about that: https://support.ultimaker.com/hc/en-us/articles/360013799339-How-to-print-the-maximum-build-volume-in-Ultimaker-Cura

    Normally the clip is the trick. You could try with this thicker clip: https://www.youmagine.com/designs/ultimaker-bowden-clip-thicker-version

    You mention the tube and collars, but is the clip that should pull the collar up a bit in place? (the blue parts in the image above; they are normally white on an S3)

    The 4th number in the distances column is the diagonal distance; that is the actual distance between the two points. The other distances are measured along an axis.

    You have probably ticked the "Origin at center" checkbox in the Machine Settings in Cura. Make sure it is not checked and slice again. Your printer firmware does not think of the center of the buildplate as coordinate 0,0. You told Cura that it does.
  7. ahoeben
    Same difference. It would mean replacing the gcode that was being sent with new gcode. Cura does not support that. Cura is very capable, just not capable of that specific feature. But if you think you can pay for software that does this for 3d printers then by all means use that software. I am not aware of any software that does, but then again I only use Cura for slicing.

    You are loading the wrong type of files. G-code files can not be altered. Load a model file instead, like an STL, OBJ or 3MF file.
  9. ahoeben
    You cannot change the settings while you are already printing. You can use the "per model settings" tool to create parts with different infill while preparing a print job.

    I have nothing constructive to add, but I just hope I am still within the hour. I would not want to disappoint you. Edit: seems like I missed the deadline by just a couple of minutes. I am sorry. I feel like I let this whole community down... Again...

    This model is non-manifold. Cura expects models to be manifold. Read https://github.com/Ghostkeeper/SettingsGuide/blob/master/resources/articles/troubleshooting/missing_parts.md#non-manifold-meshes

    Coordinates in STL files don't have a unit. Cura assumes the unit is mm, but if Blender put your models with a different unit scale in the file, then there is no way for Cura to know this. I am not familiar enough with Blender to tell you what unit Blender assumes for an STL if you change the unit for the scene from m to mm. From what happens I think it converts the units back to meters upon export. The Mesh Tools plugin (see the Marketplace) has an option to scale models from "unitless filetypes" such as STL upon load. It will do this in a way that the model ends up bigger (or smaller), but still at 100% (ie: it actually scales the coordinates). Alternatively you can apply the scale in Blender in the export to STL dialog.

    Looks like those detail are way too thin to print. Read the "Thin parts" section here: https://github.com/Ghostkeeper/SettingsGuide/blob/master/resources/articles/troubleshooting/missing_parts.md#thin-parts

    It could be that Cura does not properly handle the space in your username. To confirm that this is the issue, you could try creating a new user on your computer that does not have a space in its username and run Cura as that user.
  15. ahoeben
    If you mean the supports created by Cura, then no, there is no way to export it. Cura does not create the support as a 3d polygonal model, only as 2d lines in layers.

    If you only get the number of vertices and faces, then the model is not "watertight" (manifold) according to the plugin. You can check for watertightness with the "Check models" function. For non-manifold models, the volume and surface-area are undefined. You may need to repair the model and reopen it.
  17. ahoeben
    Please elaborate. What do you mean by "I can't access it"? Read the documentation here: https://github.com/fieldOfView/Cura-MeshTools/#meshtools
  18. ahoeben
    Unfortunately, it is.
  19. ahoeben
    Ha, I'll do you one better. It is already part of the Mesh Tools plugin. The "Analyse meshes" function will give you the surface area and volume, as well as the number of vertices and faces. I thought it only included the latter.
  20. ahoeben
    These settings are indeed not what you are looking for. Correct. Measure tool can't do that (yet, at least). How accurate does your measurement need to be? As a workaround with Measure tool, you can zoom in to the spot you want to measure in Preview, then switch back to Prepare and place the measure marker on that spot on the model.

    "See Trough" is not a profile that ships with (Ultimaker) Cura. What printer do you have? Do you use a modified version of Cura, or have you downloaded profiles from a manufacturer or community member?
  22. ahoeben
    No, there is not. I can add this functionality to the MeshTools plugin. It would be great if you could create a feature request here: https://github.com/fieldOfView/Cura-MeshTools/issues
  23. ahoeben
    It is possible that your firmware does not support 3D arcs. See https://github.com/fieldOfView/Cura-ArcWelderPlugin#allow-3d-arcs

    I don't see how someone can claim that (all) PLA is carbon-neutral. Energy goes into the making of corn/cassava/sugarcane and into the production process of the PLA, and the production of that energy may or may not be carbon-neutral. Also please don't tell people eating PLA filament is "safe". Even if the base PLA product may not kill you, you don't know what additives (colorants etc) are in the filament.

    Hover over the (i) in the Setting Visibility dialog, and you will get a somewhat cryptic hint for the reason why the setting is hidden even though you checked it. This is true for more settings (eg when you don't enable supports in the settings, most support-related settings are hidden and get such an (i) icon and explanation why the setting is not visible). In the case of the shrinkage factor, that setting is just not ready for prime time yet in the current version of Cura, so it has been disabled for all printers. I believe it will be enabled in Cura 5.0.
