I am going to try and answer because I see no one else has.
I am assuming for the moment you are referring to the cut tool and adding a threaded connector? I didn’t even know this existed until you asked about it. I played a bit with it (also on a Mac) and at first couldn’t get the connector at all. It showed the threads down in the bottom left of the print plate! But when I clicked on the part that I wanted to add the thread it snapped into place and after preforming the cut everything worked.
I don’t have anything more to suggest because that is the best I figured out on the fly, but I didn’t want you to feel like no one was listening to your question, either. I hope that it it at least a bit of help.
Thank you for replying and for trying it out. You are correct with everything you say and my attempts do exactly the same until the perform cut action, where mine decides to ignore the fact that a connector has been added and just shows the 2 cut parts neither with a thread.
I am just starting on working on creating threads. I am having the same issue with Bambu Studio (2.8.2.61) on a MAC (Tahoe 26.5.2). When you preform the cut it does not create a thread. I see a quick error message that is not their long enough to read.
Can anyone help us?
Click on the thread and it will turn blue. When you move your cursor select “Confirm connectors” the thread with turn transparent again. But it does work.
