I tried 3 different upcycling strategies on Fulgora in 2.1 and looking if somebody had similar experience or if I did something wrong somewhere. The goal: make Legendary Quality Modules 3 and Legendary Beacons.

1. Making Space Stuff

All products of scrap recycling go to Landing Pads, Space Platform Foundations and Cargo Bays.

Unaccounted:

• Red Circuits recycled all the way to Iron Plates, Plastic and Copper Wire
  • Plastic at first goes to Shredder
• Batteries and Gears -> Steel, because it is not enough, excess Iron Plates -> shredder
• Copper from batteries -> shredder

Sometimes there is too much Low Density Structures, so they becomes Steel and the rest goes to shredder.

This is very compact, quite easy to build and with some extra logic it does not jam. Outputs Blue Circuits, Holmium and Stone (excess batteries if you need them for accumulators).

Good option for beginning.

2. Deal with Excess

I started processing quality garbage and added 2 more pipelines (uncommon and rare). Making quality modules requires Green Circuits, so

• (Blue Circuits -> Green Cirtuits) + Red Circuits = Module

Great, but results in so many green circuits that you have to recycle and make them again, probably getting higher quality. Excellent alternative is to make and recycle Repair Packs, because they also help with excess of Iron Gears (found this gem too late).

Recycling modules themselves should produce enough quality Red Circuits, but EM Plants that make basic modules have to be fast to deal with input so they don't use quality modules. In the end you make modules faster than you recycle them with quality -> you need high quality recyclers (even Rare Recycler is too slow). To make it worse demand for red circuits results in getting even more Green Circuits (also need fast upcycling here).

After some time I was completely lost and run out of space, so started using another strategy -> look at item counts in stats and deal with whatever I have the most, which is usually upcycling. Following this and with help of bots I finally started making legendary modules and beacons, but the base was unmaintainable. You could find a place that tries to get rid of something right next to a place that desperately looks for that!

3. Foundations

Aquilo foundations allowed me to actually build a base right on the oil field. Did I decide to do that because after spending days building a Shattered Planet Ship I no longer can build something unless I put platform under it? Perhaps so, but that solves one annoying problem on Fulgora -> your base follows the shape of the island you are on and god that is annoying!

Besides using foundations I decided to do the opposite approach: make my own Green Circuits from Gears -> Plates and Wire (also from LDS -> Copper -> Wire) and leave Blue Circuits alone, until there are too many of them.

I also make my own Reds, because no matter what I do there is never enough. But, to make Reds you need high quality plastic and this is something that is even more rare than Reds, so I use Cryogenic Plant on Nauvis to make high quality plastic (mostly Rare). On Fulgora I then decide if I have too much of it and try to upcycle it to higher qualities.

After I finishing Green and Red production I made a stupid mistake - let bots deliver quality wire wherever they wanted, thinking that round robin should be fine. And it is fine in general, but since I didn't have enough plastic at that time I ended up creating 10000 legendary green Circuits and wasting ridiculous amount of wire. I hope there is something useful I can make of that.

To fix the mistake I setup Quality Wire production on Nauvis (legendary foundry) and import it similar to plastic (although uncommon wire I feed to bitters in a powder form).

One important difference from previous approach is that I no longer make anything like Landing Pads or Centrifuges - waste of time. In current 2.1 Concrete fortunately can just go into recycler never to be though of again.

Conclusion

Plastic!
