Poor/mid air supports #219

Open tbeesto opened 3 years ago

tbeesto commented 3 years ago

Auto supports in canvas produce poor/mid air supports. Custom also seem to do the same. I've not tried it with other models, first time with printing a model that needs supports in canvas. The model used was groot planter: https://www.thingiverse.com/thing:3055889/files.

To Reproduce

  1. New project, single material model, add stl.
  2. Was using paint feature.
  3. Configured supports as per below.
  4. Slice.

Expected behavior No mid air supports, supports should start from build plate. Lowering the inflation and horizontal gap does help, but does not reduce it completely.

Hi @tbeesto,

Thanks for writing up this issue and being detailed with the report!

I think horizontal offset is the factor causing floating supports in your case. By decreasing this value I was able to get better results:

If you would like more aggressive supporting structures, consider increasing the horizontal inflation, switching the support density to high or potentially adding dense support interfaces.

In these cases I would definitely recommend custom supports so it is only being generated where you would like. This should help minimize support removal time or any aesthetic defects. A quick tip for custom supports is to use 'Auto-generate' to get a rough idea of what you're looking for and then fine tune from there:
