  1. I verified that the Schwartz P also has the same shape of the overhang angle occurrence plot. Are there more TPMS which are defined by an implicit function?
  2. According to my analysis the Schwartz D is exactly as printable as the gyroid, with normals concentrated around 45* overhang. The Schwartz D surface is definitely more stiff, though, seeing as it has straight lines in it. Can't find an easy stl for the Schwartz P surface for my automated analysis. Perhaps I will have to generate it myself in MATLAB just like I did for the gyroid.
  3. I've been studying triply periodic minimal surfaces (TPMS) quite a bit. There are numerous other surfaces. This site has a very extensive list: http://facstaff.susqu.edu/brakke/evolver/examples/periodic/periodic.html#gyroid One important criterion is that they have no overhang, but even gyroid surface violates the overhang angle. We might want to relax the criterion of being minimal, and alter the gyroid slightly in order to satisfy overhang constraints. However, that would require some mathematical trickery which I haven't delved into yet. Another idea is to rotate the patterns if there is one orientation in which there is considerably less overhang. @Noisettetbou Please share any results you found. I am very interested. It seems to me the Schwarz D is very anisotropic; does it have those straight diagonal lines only in one direction?
  4. No it shouldn't. But to be sure you should make a backup of your configuration folder of 4.0. If there were some major changes since 4.0.0-beta2 then your profiles could potentially crash Cura. Eitherway you should update to Cura 4.0.0; you cannot stay on 4.0.0-beta2 forever; problems in updating from beta2 to stable are probably caused by beta2, not by the stable version.
  5. That sounds like your CuraEngine is another version than the frontend of Cura. Perhaps something went wrong during your install which causes your Cura to use the another CuraEngine than the newly installed one. Another e[explanation would be that the wrong version of CuraEngine is packed into the installer, but that would cause errors for everybody. Whoch operating system are you using?
  6. What's the last couple of lines in the log file? (Help > Configuration folder > Cura.log)
  7. Minor issue in dark mode with the printer icon:
  8. I cannot select the layer view range any more. That means I cannot scroll through the layers using my arrow keys anymore, while viewing a range of layers. The functionality used to work in 3.4.1 Got partially broken in 3.5, and now the functionality is gone: Dragging the layer range still works, though, but it doesn't give the same level of fine control.
  9. @gr5CuraEngine.zip Here's a compiled linux binary of the backend. There's no frontend for it and in order to get it to work you will need to do a super fine calibration. I've put some documentation out there on how to get this to work via the command line, but it's certainly not easy. Unfortunately I don't have the time to make a step-by-step guide on this. I'm not sure whether providing this binary helps, but please share your project in case you get it figured out!
  10. So the goal is to get the gyroid infill to show on the outside because it creates pretty patterns..?
  11. Please snooze your alarm, or shut it down completely. Support Infill Line Direction is still an option in Cura 3.6. Perhaps it was not visible because you didn't enable support.
  12. It is working for me. I first made the mistake of setting the infill pattern on the wrong extruder, though. Perhaps you made the same mistake. I'd like to add that the gyroid infill has some very interesting properties. - The gyroid infill acts like a spring. The force and amount of compression in mm seem to be related quite linearly. - The gyroid pattern splits the infill space into just two regions. Every hollow space is connected to half of the other hollow spaces. This makes it really easy if you want to fill the print in post-processing to give it more weight and to make it solid.
  13. It seems to me that it is trying to fill a large volume from only the most north part. If your filament would have been liquid it could have filled all the cravices. You shouldn't be using Spaghetti infill on solid filaments; it's supposed to be used on liquid filaments. Please use Infill Thickness if you want to print infill only every couple of layers.
  14. I was replying to this user who is still on Cura 2.4
  15. Maybe you should consider updating to a newer Cura, rather than to Simplify3D. Cura 3.5 just came out. Cura 2.4 is rather old. Your problem may have been solved a long time ago
