Simple orbital for Vulcanus to drop iron ore, so you can make concrete for foundries on the surface without having to ship iron ore to the planet.
If you do not have asteroid reprocessing (for crusher) yet, rotate the two long handed inserters at top left to dump the unusable chunks.
Has simple starter foundry setup to start making other items if you wish for other planets, like dropping iron plate to Aquilo. Delete if not needed.
