Perfect farming ring; that is, a tropics-filling ring that farms all 60 DF drops with no possibility of backing up. All 60 items are piped onto 60 dedicated belts via filtered BAB slots and sorters, then sent to ILS to export elsewhere. If one item backs up, the other 59 continue to be picked up and exported as normal.
* ILSes are set to be on priority group 1, so your ILSes on other planets can also use group 1 and will prioritize taking from the farm ahead of other planets. Each ILS only uses 4 of its slots, too, so that gives you 15 slots to use for incoming necessities.
* A number of the support BABs have depot logistics set up to receive laser turrets, to keep the ring stable. You'll need to provide the laser turrets on your own; you can make them locally from farmed materials easily.
* You'll need to supply your own power. Thermal plants burning the farmed DF energy shards and hydrogen should do just fine, with some accumulators to handle laser spikes.
* This build requires yellow science for building height, and uses a mix of Sorter 3 and Pile Sorter. You can downgrade those if necessary. It unfortunately (and obviously) requires purple science to actually *use* the blueprint (Mass Construction 5). I also offer blueprints for the individual pieces that are small enough to only need Mass Construction 4 (yellow science), they just require a little more manual work to put together.
