Full limitations for IceSL
  • The program is closed source and comes out of a research group, so documentation and printer profiles are thinner than in the mainstream slicers.
  • More settings exposed than a first-time printer owner needs
  • Copycat sites such as orca-slicer.com push unsafe downloads, so use orcaslicer.com
