  1. Wire printing was removed in Cura 5.4. According to the release notes, it was "broken and barely used". You could try Cura 5.3 (https://github.com/Ultimaker/Cura/releases/tag/5.3.0), or let us know what you mean by "it is no longer working" and perhaps we can help you to (also) get that version to work again.
  2. The extrusions will have relatively low number number of steppermotor steps, so there is less precision in how much material gets extruded on a move. There is no hard limit of what is "ok" and what is not, but with a lower layer height, you get less precision in how much material gets extruded, so (theoretically) you get very small under- and over extrusions along the print due to rounding. This is even more a problem for "relative" extrusion mode, since the rounding of steps happens at each move instead of over a full print.
  3. Cura tries to protect your printer against cold extrusion. Cura tries to see if there is anything in your start gcode that heats up your extruder(s), and bed. If not, it will insert a heatup sequence on its own. Cura does not know about your PRINT_START macro. The logic is here: https://github.com/Ultimaker/Cura/blob/4.4/plugins/CuraEngineBackend/StartSliceJob.py#L428 Cura looks for the text "{material_print_temperature}", "{material_print_temperature_layer_0}", "{default_material_print_temperature}", "{material_initial_print_temperature}", "{material_final_print_temperature}" or "{material_standby_temperature}" in the start gcode to check if the start gcode contains extruder heating commands (so it does not actually care if you use M104 or M109 or not). Cura looks for the text "{material_bed_temperature}" or "{material_bed_temperature_layer_0}" in the start gcode to check if the start gcode contains bed heating command (so it does not actually care if you use M140 or M190 or not).
  4. I have never printed a benchy myself. I went to 3dbenchy.com, and downloaded the 3d benchy hosted on Thingiverse.com. 3D Builder (by Microsoft, ships with Windows) agrees with Mesh Tools that that model is "invalidly defined" (which is what 3D Builder calls non-watertight). Just that a model is printed a lot does not mean that it is a perfect model. But let's not focus too much in this topic on what is and what isn't watertight.
  5. Is Cura itself, or the Mesh Tools plugin telling you that it isn't?
  6. There is no such thing as Ultimaker Cura 4.1.3. There is Ultimaker 4.13 (which I think you have), which is newer than 4.6, 4.7 or 4.8. You can download 4.13.1 (the latest from the 4.x releases) here: https://github.com/Ultimaker/Cura/releases/tag/4.13.1 Other releases can all be found here: https://github.com/Ultimaker/Cura/releases/ (You will have to scroll)
  7. You don't have to turn off the plugin; you could just turn off the warning if it is annoying you. Though it is there for a reason.
  8. The one in your screenshot is shown by the MeshTools plugin. If you want, you can turn them off in the settings for MeshTools (see Extensions -> Mesh Tools -> Settings...). MeshTools checks if a mesh is watertight by making sure every edge ("line between two vertices") of the mesh is included in exactly two faces.
  9. The message means that Cura thinks there is nothing printable on the buildplate. Is your model on the buildplate, or has Cura placed it off the buildplate? Could you share a screenshot?
  10. It uses a fork of a very old version of Marlin as part of the firmware. It would be a LOT of work to rebase the changes that were made to the Ultimaker fork onto a more modern version of Marlin.
  11. The screenshot uses the "search..." box. I hope I don't come across as pedantic or hijacking a thread. This is a forum, not a ticket system. If people finding this discussion get some context and learn that there are opposing opinions about making all settings visible, then I think that is a good thing. People recommending making all settings visible as a first step is a pet peeve of mine, which is ironic because I implemented the first version(s) of "Show all" long ago... It has its uses, but not for people starting out.
  12. There you have it... Again, I recommend you don't (and urge people to stop recommending it!). Not only will this make the list of settings unwieldy to navigate, scrolling through literally hundreds of settings you will probably not use every time you want to change something, but it will also be a lot slower to use that very useful "search..." box.
  13. For the benefit of those finding this page via a search engine, there's a plugin implementing tabbed settings in the Marketplace. Some more information here:
  14. On the top of the second screenshot, you can see that that user has typed "support" in the Search... box. You can also search directly for "Support Pattern". If there's a setting you use a lot, then you can choose to keep it in the set of visible settings when the "Search..." box is empty, by right-clicking the setting and choosing "Keep setting visible". Some users will recommend you make all settings visible. I recommend you don't. Only use those settings that you often change, and use the search for the rest. You might also want to try the Tabbed Settings plugin which will show you the full list of settings per category:
  15. Nah, we are all very good mindreaders...

    I think OpenGL Extensions Viewer shows what the hardware supports, from a database of known GPUs. It does not show what the driver actually supports. I could be wrong though.
  17. I am sorry, I did not properly look at you model. You are right, the model does have an inner and outer wall. The problem is that the normals for the connecting loft are flipped AND that the loft has no caps and the two parts that it connects do have caps. So there is a single wall between the parts and the lofted connection, and that makes the model non-manifold. However, in this case because the non-manifoldness is parallel to the slicing direction it is not a problem for Cura. It would be a problem if you wanted to print the bottle on its side. Your model slices correctly in the orientation you have it now if you fix the normals. This can be done with the Mesh Tools plugin from the Marketplace.

    You could try this "Compatibility Pack" from intel: https://apps.microsoft.com/detail/9nqpsl29bfff?hl=en-us&gl=US Please tell us if that works. If it doesn't, there's also this hack, again please let us know if that works, so we can tell other users with old hardware about it: https://github.com/pal1000/save-legacy-intel-graphics
  19. And Cura is right. Your model is non-manifold. Specifically the double-curved surface between the main body and the cylindrical top seems to have no thickness (and is inside-out). This makes the model unsuitable for 3d printing. Being suitable for displaying the model and being suitable for 3d printing the model are two different things.
  20. The Marketplace button in the top-right corner of the Cura window. Though Marketplace seems to imply that you have to pay for stuff, all of it is free, and you do not need to be logged in to an Ultimaker account to use it.
  21. Disable the USB Printing plugin (via the cogwheel icon in the Marketplace), and Cura will no longer touch your USB ports.
  22. Note that in order for ArcWelder to work, your printer firmware has to properly support arc movements. Not all firmware versions do.
  23. See this article: https://www.howtogeek.com/351522/how-to-choose-which-gpu-a-game-uses-on-windows-10/
  24. Congratulations on having a printer that is a couple of years younger than you thought!
  25. Do you have an Ultimaker Original, or an Ultimaker Original Plus? The Original came with a wooden printhead, the one on the Original Plus came with a metal printhead. Make sure you add the proper model to your Cura, as the firmware is significantly different and gets selected by you having the active machine in Cura properly selected.
