How to reproduce

  1. Open the attached project file.
  2. All settings are set to reproduce the issue, so just click slice plate.
  3. Observe the low support layers (layers 1-10) near the center area of the main crab body.

Actual results

After building up the initial layer on the ground, the slicer proceeds to build up a few layers of the auto tree supports around the perimeter. However, at around layer 7 or so, it begins to split the main auto tree cluster in several sub-trees, but in this case does so by printing supports in midair: image.

I did not notice this at first and attempted the print, but it seemed to fail in exactly this location for presumably this exact reason. So I know at least that it is not simply a visualizer issue in the preview.

Expected results

If the tree cluster needs to be split into sub-trees, it should start building up their walls from the very beginning rather than waiting until the fork in their surface topologies (which I believe is what it actually is doing).

Yes, that's one of the known issues with organic tree support (the current default). You can try hybrid support instead.
