OK solved with version 2.7

Hi, I upgraded to 2.5 these days To me, the bug is only partially fixed. Here is the remaining problem: As shown higher in my image: with an overhang angle set to 40 degrees, the support on the left side was getting down to the build plate. But it should not, it should stop and rest on the intermediate plane. With version 2.3 you can see that only one half of the left side go through the intermediate plane. With 2.5 all the left side support goes through it, down to the build plate, which is worse. As I understand there's no need to make the support forcibly touch the build plate. Best regards and thanks for the effort

OK I'll give it a try if needed. For now I will wait for 2.4 I found two work arounds for this bugg in 2.3.1: - flatten horizontally the top surfaces - thicken the model (plane or beam or whatever) Thanks for your work This slicer is giving very good results

I am not using towers. I tried conical support without success May I try the current CuraEngine to see if the problem remains ? Did you try it ? Is it difficult to run the git version on debian 8.2 ? Thanks

Thank you, but I'll wait for a Linux version For now I forwarded this thread to the github CuraEngine issue tracker: https://github.com/Ultimaker/CuraEngine/issues/421 Thanks again

Yes, I need this bug to be cleaned because it's annoying me for a much more complex print that I cannot rotate.

Hi Thanks for the software Cura is wrongly guessing the support on the example below Here is the STL file and the view: The model is a Y letter whose top is partly flatten horizontally and partly square. The Y top branches have a 45 degrees angle with the horizontal plane. The is also, beneath, an intermediate plane with a 70 degrees angle with the horizontal plane. The intermediate plane is not intended to be supported. - - - [media=26604] [/media] With a overhang angle set to 60 degrees, there should be no support. But see above, there are supports. Just like if the square tops of the Y had to be supported. Moreover, one support gets down to the build plate where it should stop and rest on the intermediate plane. - - - With a overhang angle set to 40 degrees, normal support kicks in, but there is still one support getting down to the build plate where it should stop and rest on the intermediate plane. - - Here is my profile My cura version: 2.3.1 - Regards Eric
