Start underground. The Nauvis surface is hostile and normal surface construction is forbidden; dig out cave space, use shafts, and build your factory below.
Factorio supports linking pipes/wires/chests across surfaces, this would remove the need to use lua to shuttle items/fluids/signals between floors which can scale poorly as the number of these entities grow; especially for signals.
If you want to force fixed fluid flow, a hidden linked pipe and then a pump entity would work.
That’s an interesting approach. I’m also working on a mod that transfers items and fluids between different surfaces using Lua. I haven’t tested linked containers and pipes for this yet, but I’m going to look into it. If it works reliably, it could be a cleaner solution and reduce script overhead. Thanks for pointing this out.
You can use radars in stock to transfer signals between all surfaces by a channel, so there isn't any point to adding an item which only moves signals across every few seconds.
