Custom supports in Blender

[danilius 118]

I have tried creating support in Blender and found that anything thinner than .441mm was ignored by Cura. The supports that did print were two lines wide, which of course is not what I want.

What I'm wondering is if there is some way of creating single line wide support from within Blender. Is there any way of marking geometry in such a way that Cura will treat it as a support, or perhaps some other slicer that is capable of doing that?

I am loath to try slic3r at the moment, because I'm not confident enough to configure it for the UM2. Is there anywhere to download pre-configured settings for the UM2 in a file for slic3r?

Did you actually print it? I also found that 0.4mm is not thick enough for Cura (at least not without the fix horrible B setting). I once made a 0.5mm support and sliced it with Cura. And the width of the print is: 0.5mm! Cura does indeed draw two lines but one of them is drawn with just about a quarter of the volume and shifted by 0.1mm in respect to the other line. Very clever!

I did print it, 10mm tall. It was quite cool, but still too thick for my purposes. Maybe I just have to fiddle a bit more.

I do the same for my custom supports.

Maybe with some hack in the code you could tell cura to single lines on the open faces and provide non watertight geometries... Maybe...

I can't wait until we can start printing single lines!
