The thing that’s printing on the preview is the support itself, it’s not the last layer since the roof of the model it’ll need to support is curved, I have the “support roof” setting enabled but it doesn’t come in for 4 more layers.
Model is not mine but I might think about modifying it. But as I said, this part printing & turning in the air is not a part of the model but a generated support underneath.
[support tweaking] Any ideas how to make Cura treat situations like this with a bridge instead of making turns in the air? (discuss.tchncs.de)
