Cura 4.8 Support Blocker does not work

[titust1 1]

I'm using Cura 4.8 and I want to block all support by using "Support Blocker" but I can't.

I click the 6th button on the left (which does not have tool tips), I make a cube, enlarge the cube to include completely my object in the cube. then slice. In the preview I can see that Cura is still creating supports. Why is that? I don't get it.

Thanks a lot

If you use "File | Save Project" and post the 3mf file here, someone will take a look.

It isn't support...Cura is making the overhangs printable buy putting chamfers in to support the ceilings...or something.

 

Go to "Experimental" and de-select "Make Overhang Printable".

Thanks, it worked. Highly appreciated.

I didn't know exactly what "make overheads printable" meant.

I though it would force printing even with overheads.

This feature is kind of useless because there is no way to remove those chamfers, I tried.

Thanks again

"Kind of useless" may be an understatement.  "Confusing" is another word that applies.
