Mystery Supports?

[mike-truly 3]

I have a print using support 'everywhere'.  Most of the supports are understandable as they support the ceilings of holes and such.  But there are a few supports where I don't really understand why they are there:

 

 

They are below some hole areas however they are not connected to the holes and they don't really seem needed.  One of these mystery supports has broken loose from the bed during printing and fallen over and therefore the print head prints out in space when trying to add to this support.

 

Any idea what these supports are trying to support?

 

Thanks!

And here's a screengrab showing nothing needing support in these areas:

 

 

Thanks!

Hi, I think they come as a side effect of the Enable Towers option.

Maybe they try to support the supports of the holes.

Try to switch to only buildplate, maybe they are gone then.

I don't think this part needs any support.  Or at least enable support only touching buildplate as conny_g says.  Personally I rarely use cura support and instead generate the support myself in cad.  I would create two arches in the front and back of that large cylinder and do zero support in between (let it bridge across the arches.
