2.3.0 (Release) Support Placement Issue

Recommended Posts

There seems to be a significant Support Placement issue in Cura 2.3.0. It appears to be placing much more support than is needed and in places that don't require any support.

Normal View: Red indicate Overhang areas (right?) 5a3322c66a71f_NormalView.thumb.png.122e380e63f44852dc03fa12be0ebc3a.png

Layer View: Supports just about everywhere - especially where the overhang is almost 0!5a3322c68ec3d_LayerView.thumb.png.3e8c35d03107ccc7a212b7c69e7143cf.png

This is Thingiverse Night Bat rotated to 150 degrees backward (as instructed) and scaled to 1000% (so its a decent size).

Here's an 80% overhang. Notice how virtually None of the near horizontal surfaces have any support:5a3322c6bd5b1_LayerView-80.thumb.png.9d0a6932a8cee6c88e49132dc08a4463.png

Lasty a 90% overhang, which the help text says will provide NO Support (ooops):5a3322c6ec278_LayerView-90.thumb.png.f93f2c74444933d605cc6af62eeebd03.png

Am I doing something wrong/stupid, or is this really horked??

I created a simple arch where each inside segment was rotate 10 degrees and tested the Suport Placement again.

It works as expected with supports being placed according to the degrees specified.

I tested 10 - 90 degrees and they all placed properly - with 90 degrees having no support and 10 having everything supported.

So apparently Cura is just going Batty (sorry) with that model's supports.
