  1. one thing we have not really talked about is; Is having the ability to slice internal walls a feature that is useful or not? You all know my stance on this by now. What is yours?
  2. thanks for the heads up regarding the screws that can come loose. never thought about that yet
  3. Thank you Greg for the 3mf file. On my end though I can see 2 remaining issues that would hinder using this technique. 1) The wall in the middle between the inner and the outer part is 2 lines thick, even when setting the wall count to 1 of the eraser used there. 2) The walls connecting the magnet hole do not appear on layers before layer 6 would it be an idea to change this topic to a feature request? To also be able to slice internal walls?
  4. Interesting, how does this working with erasers work? From the screen shot I am not sure I understand.
  5. I have a piece of a magnet holder. It needs to be stiff so that is why I need internal walls. I have asked about something similar in the past but this time I have a better model that is closed. In the image above the upper model is actually 3 separate models merged together to have them in the same location as they were during STL generation. Now the internal walls are overlapping but that is of no concern due to the "union overlapping" feature. When slicing the inner walls get sliced as well just as I'd like. Below it we have the same model yet exported as a single STL. Now the internal walls are no longer being sliced even though they show up in the x ray view quite good. Is there a setting I am overlooking that will get the internal walls sliced on single STL models? If it is not possible it would mean a tremendous amount of extra work splitting up larger models into many smaller pieces. Please see the 3fm file for reference.

  6. I'll admit it is working around the issues my sub par quality printer brings. Thanks for the suggestion, I'll take a look at it and if I get stuck then I do not mind baby sitting 😉 it's not too long of a wait before I can leave the print.
  7. correction, they are a combo of inner wall and a shell
  8. Perhaps I misunderstood the OP. Please see my screenshot in my scenario those holes on the build plate, which are walls, almost always fail. They come out curled up and are getting stuck on my BL touch. In my scenario the outer walls are not a problem though. If we could just start with the bottom skin only on the first layer I thing the walls on the second layer will stick much better. The alternative is to baby sit my print and remove all the failed circles (walls) during the first layer.
  9. My I second this feature request? For me it is exactly the same as the OP but also with PLA. Starting without walls on the first layer would be the solution
  10. @MariMakes thank you for this illuminating response. I happened to come across it though only by chance. Somehow I am not receiving emails when responses are in. Is there a forum setting I have overlooked or is there a known issue with notifications at the moment?
  11. Using cura 5.2.1 I'd like to have 2 separate models placed overlapping in a very precise way. On the left we see a single model (exported as a single STL) that is what I need to end up with. In the middle we have part of a disk that should be placed overlapping to the teeth model on the right. The end result should be just like the model on the left. Reason being is that I am printing functional parts and the middle disk part and the teeth part have different print settings. The problem I have is that cura automatically drops the models on the build plate (even when disabling that feature in the general settings) and the orientation of the models in relationship to each other is lost during importing. If the orientation would be preserved, even though models end up on the build plate (basically overlapping during multiple model import) I am already helped a lot because then I could simply adjust the z axis on the disk model. It is getting the models aligned in terms of orientation that has me struggeling at the moment. Please find attached my cura project file. Does anyone have a suggestion on how to do this?

  12. problem solved. I had to set the top and bottom layer thickness to 0. now it is exactly slicing like I have the model.
  13. Yes thank you, the model looks good in your cura. There was no need to repair the STL though. That red part you repaired was a start of the stiffeners I was in the process of adding but forgot to remove just before deciding to post here. The new project I have attached has the stiffeners finished so no errors in the model. But the same issue is now more pronounced as can be seen in the images in my previous post. I also had this theory regarding support but disabling support did not do the trick for me 😞 Anything else I can try? CE5P_magnet holder quarter with walls.3mf
  14. I tried disabling support as it could have been a support artifact for that wall that starts 2 layers later. But since the model is a solid (100% infill) there is no need for support there. But that did not do the trick 😞 I have added some extra stiffners that also should be solid. Also those get visible on the first layer. Please see a section view. and this is the first layer in cura this leads to less efficient print times and increases the failure rate of the first and subsequent layers. Layer 1 and 2 ( the first 0.9mm) should be homogeneous. So the print head never should have to stop and make sharp corners or anything. Layer 3 should have these shapes on it visible now on layer 1 and 2. I can force cura to not print these shapes the first few layers by increasing the distance between the bottom of the model and the lowest top layer. But that makes the solid too high in the lower parts.
