Problem With Support

[minuteman64 4]

Using Cura 4.13.1 and printing with a 2mm nozzle.  Trying to print out a small part and having problems with the support (and the print in general).  Basically the support is getting fused into the structure.  Won't separate easily and the smaller details are clogged with what I assume are portions of the support.

 

Attached photo shows some of the problem area.  No separation between support and structure.

 

Previously did the print with Cura 14.07 or 3.xx (cant remember for sure which one) and it came out almost perfect - and, of course I deleted that file when I upgraded to current Cura version.

 

Sooooo many settings 😞  Any thoughts on where to look to resolve?

 

Also attached (assuming it will attach) is my Project File.

Actually, the more annoying problem is on the other side.  Photo below.  The portion being supported is at the top (it's a hinge leaf shown from the back).  The support for this starts on the bed way wider than needed and the support extends to cover the bottom of the hinge leaf.  The support only needs to be the diameter that is between the two parts of the hinge leaf.

 

To get a functioning part I'll need to clean up the support issue in this area.  How do i decrease the footprint of the support on the base?

Apparently it had something to do with the "Tower" setting (which I didn't at the time know was an actual thing).  I was experimenting (in Preview) with various Support options.  Turned on "Tower" just to see what it would do.  No change.  Then turned it off, and the extra support went away.

 

I now have a usable (but not great quality) part.  I'll continue to play with this object/support settings to attempt to achieve "perfection."  A learning exercise.
