I've built the same setup on 2 iron volcanoes and this copper volcano, and the iron moves around with no issues. The copper however seems to ignore the aluminum tiles ive placed for heat transfer, leaving 400 degree copper running on the conveyor rails. If I watch the system, it leaves the build at about 30 degrees with the cooling, but offscreen it ignores all of it.
Steps to Reproduce
setup high temp copper to travel through solid tiles, in this case aluminum metal tiles, offscreen. They seem to not transfer heat offscreen.
This issue has not been confirmed by a developer yet.
