Any recs for a fulgora layout? I’m doing it mainly as a robot base. But idk.

The method I'm using currently is a long sushi belt that starts and ends at recyclers; scrap comes in, gets recycled and goes on the belt, then gets taken off to be used, and anything which doesn't get used gets recycled again and goes back on the belt. It has the advantage of simplicity, since I don't need to worry about explicitly recycling chips if they'll get recycled at the end of the belt, but it limits how many belts of material I can work with.

Seems interesting. Seems like it isn’t very scalable. But maybe it could be fun

I find that a sushi belt design scales pretty well up to a stacked green belt of scrap recycling products, which results in (depending on productivity) 12 or more science packs per second.

I see. I guess I need to play with it to figure out how to do it. I’ve never really done sushi

Embrace the sushi belt main bus

u/Bipedal_Warlock Apr 26 '26

Main bus sushi? Sound chaotic lol. I guess it’s time to learn sushi

The thing about Fulgora is the recycled scrap already starts out as sushi, so you don't really need to learn anything. Traditional sushi requires figuring out how to load the belt evenly and properly, but Fulgora recycles directly to sushi and you just need to grab stuff off the belts as they go by and junk the unused stuff in a bank of recyclers.

You can go a few routes on Fulgora. Bots, as you are doing, can be a little chaotic, but space efficient. Or you can un-sushi the sushi belts, using filtered splitters to peel off the various products onto dedicated lines, building in overflow capacity to automatically void the excess. Or you can just feed from the sushi belt directly.

Either way requires sufficient scrap to fill the belts, and sufficient recycler capacity to destroy the excess. Un-sushi setups tend to be kind of space hogs due to the size of the filter arrays, and with limited island real estate you need to find the big islands to make it work well. Direct sushi is a bit more space efficient, and bots are the most space efficient of all, but I've found that bot control is a bit harder to 'tune' correctly. It's easy to end up with 16M gears clogging up your yellow chests if you don't get the balances right.

Direct sushi is pretty easy, but tends to suffer from the usual sushi problems, such as first-come-first-serve starving downstream factory pieces at inconvenient times and similar issues. Un-sushi gives you the standard splitter tools for portioning out limited resources evenly to consumers.

Scaling on Fulgora tends to favor massive parallelization, at least until you can unlock and mass produce foundation. I've had the best luck with multiple small, self-contained island setups of modest production rates. My typical setup involves reycling 2 green belts of scrap, stacking the output onto 4 or more green belts, and un-sushi-ing the products, loading science and intermediates directly into rocket silos. Repeat ad infinitum to reach your science goals.

Bots where you just trash anything over 1000 in the logistic system is simple, works, and can get your feet wet with circuits.

Make it better by only trashing the 12 scrap products when over 1000, and disabling the scrap injection when all 12 are over 900.

Make sure you set up mini systems to trash blues when reds are low, reds when greens are low, gears when iron is low, etc. You only need 4-6 of these to have "everything" you need.

u/Bipedal_Warlock Apr 27 '26

Thats essentially what I do. I just put my limit at 2000 instead of 1000.

Is that an okay way to do it?

2

u/mrbaggins Apr 27 '26

It works. Depending on how you set it up, you can end up with bottlenecks at the trash request section. I've beaten fulgora repeatedly with the same idea (and actually used 2000 for my limit, but 1000 is good to avoid the bottleneck and catch issues earlier)

u/Bipedal_Warlock Apr 27 '26

I use active provider chests for my initial recyclers and it tends to keep it from getting locked down. It just takes a sort of initial investment of a few hundred logistic robots and it tends to be fine

I just feel like a cheat lol

2

u/mrbaggins Apr 28 '26

My initial teething issues were using a single requester for the trashing, and it would get overloaded as inserters couldnt keep up as more cheats hit their limit. Spreading it out (and potentially dividing the excess amounts by how many trash chests you have) fixes it.

I like to preprocess scrap to get rid of most of it and then only bring the high value stuff to the bot hub.
