Like many on these forums I have been having trouble getting rafts to separate easily from my PLA prints. I looked at a few threads and just went with making a secondary raft process that prints at a lower temp and slower speed with max cooling to set the raft nice and solid so that there's less of a thermal interface for the print to amalgam with.
So far, my results haven't been great (adjusting separation distance seems to be useless as well), but I think what could benefit raft removal the most is the option to set the raft infill pattern to something other than rectilinear. I couldn't find a way to do this in S3D, though. I thought at least that setting the external fill option for a concentric pattern would work, but that sadly does not affect the raft's infill layers. Ideally, I think Wiggle or Triangular would work best.
Has anyone figured out a way to do this? Is there a way already in S3D that I missed? If not, should this be a feature?
