Weird, I wonder why Sprut or Tormach dropped support for header info from just the lathe? I'm guessing that Tormach never got back to you on your message about the issue.
BTW, Tormach has a Discord "forum" for SprutCAM support. Not much traffic there, though I seem to have lost access to the Support channel there.
