This scheme use 1536/s raw common tungsten ore (need 7 full belts), and give about 550/m avarage legendary tungsten steel! Also use about 13k/s molten iron and 2,3k/s lubricant. Also need about 200-400 logistic bots to work it (quantity depend from bots speed technology level) Good luck to feed this machine! Please give me like! I think it is great scheme what give good amount of legendary quality tungsten plates.
Coution! Underground belts carry by bots, so bots network must be separate from your main base, or they will burn all of your underground turbo belts.....
P.S. this scheme better to build after you already get 3 primal legendary resources - coal, iron ore and calcite. Good way to use Nilaus method with farming them on space ships, with them you can build most of vanilla items legendary, and then build more advanced schemes for getting more rare and hard resources. Look also my 180/m Legendary Holmium plates scheme on Fulgora!
P.S.S. Need build only 21 modules like this to get 240/s Legendary Metallurgy science!
