I have 2 solid objects, and a boolean subtract (tried with union too) does not work. The circular object has a tiny gap since I created it flat then deformed it, but that should not be the problem I guess.
after clicking 'done', it says "calculating" for a few seconds, then returns to the default state, but no boolean operation has been performed.

any thoughts?

oops, the file is too big, 69 Mb, can't make it any smaller.

Hi Wim, from the darkness of the edges in your screen shot it looks like you may have some duplicated objects stacked up on top of each other.

Can you extract just one piece of the knurling and the box? That should make a smaller file.

Michael,

there are no stacked objects, in the object list there are just the 2 objects you see, I deleted everything else.

It must be related to the small gap in the ring, I was able to boolean a large part of the ring, away from the gap, that boolean operation worked. still does not work with the cube though.
the file was reduced to 34.6 Mb, but still would not load, I made a zip file, 20 Mb, then I got "internal error 500, could not display the file you are looking for".
I will try to reduce it further tomorrow, it is quite late here now.

Hi wim, you may need to use a file transfer service like https://wetransfer.com/ or dropbox and send me a link through e-mail at moi@moi3d.com
