Cura 4.2.1 midair supports.

[lospo 0]

I can find some spot of support nearby the object, is this a bug?

Is there a way to avoid this?

 

Thanks

I've found supports to be very unreliable in 4.2.1. I've had numerous problems with supports missing bottom layers so they don't adhere to the build plate and also being generated for no apparent reason. Really frustrating and unfortunate that Ultimaker would release such a buggy mess.

Had to revert to version 4.1 to get supports to work more reliably.

Are your support settings on "touching buildplate" or "everywhere"?

If it's the second one, try the first.

Also, you can try to set another support angle. I think it's 45° by default, I'm using 55°.

Tweaking angles sometimes makes it go away, changing layer heights can 'fix' it as well... but I've see/reported the same/similar issue when printing miniatures in 3.6 and I think it was still a problem (different, but a problem) in 4.1
