Support not working on really small items since 4.0.0

[WulfC 0]

I realise I'm probably the only one here who even tries to print really tiny tanks (1:600, under 1cm long), but it worked fine up until Cura 4.0.0. After that, there was a strange failure in the slicer trying to use supports. The support went so far, then just stopped, often at a demarcation line, like the bottom of the turret.. Now, this only seems to happen on really small models, but it did not happen on 4.0.0 and before slices.  Is there some setting I'm not using that affects this? Has anyone else seen the effect? It will work if I use tree Supports, but Tree Supports just don't support straight lines as well.

 

Screenshot attached - note that, without towers, there's just nothing at all under the gun barrels...

Minimum support area setting too large?

Excellent! Thank you, a setting I never knew existed, it certainly looks good in preview. I'll test it tomorrow.

Great, looks like you've got that penny pretty well surrounded!

out the box Cura hides alot of settings, you can pick to view all settings by clicking on the menu icon next to the settings search box, you can also type in "Minimum support area" in the settings search box also to fine it and it will be in the support part of the settings.
