I been having an issue with the supports generated by S3D.
Could it be possible that when generating the support, that within the support a border is printed the sits within the boundary of the solid support layer. so that the ends of the solid support layer can sit on it.
I was thinking to print it as part of the first layer and then every other layer there after.
it's been too often that I have had to print at a high support density because the solid support layer isn't supported and fails to do its job of SUPPORTING the part.
