Hi, well fresh start. I tried using 3mf, step and stl files. Without success. Which is irritating. Today, I refer back to the thread that got my interest. It is the one above in this thread titled “An even better example” from Dec 2023. This refers to a printables file
https://www.printables.com/model/406627-activated-carbon-filter-for-bambu-lab-x1-carbon-3d
I only downloaded the file- Activated Carbon Filter Lid.stl
I know that it’s possible, because there is the proof. It’s just that I cannot repeat it. Here is the Prepare view. I moved the modifier downwards and slightly outside the target, so that it spans the perforated lid.
Here is my result. Notice that the modifier does take effect on the edge, but it does not modify the perforated part.
I’m disappointed that I cannot get it to work, nevertheless I have discovered a really useful feature that’s available in the slicer. So chuffed with that. I hope that someone can point out whatever setting/action that I have missed.
