Does the R node really drop something ? I can ' t still find anything . <| sep |> What exactly did they do . ?<| sep |> you use a ton of circuits , more than any other single item , by far . So you will inevitably want A LOT of them . I believe ironcartographer is saying he would want 2 full belts , I suspect hes speaking of blue belts at that , and he ' s probably low balling a bit for a large factory or a lot of bit for a mega factoryIf we look at the recipe , you need 3 copper wire and 1 iron plate , so in theory you need 4 ingredients to 1 product . so if you said you wanted 1 full belt of circuit , you ' d need 4 belts coming in , 3 for copper wire , 1 for iron plate . It gets a little bit messy if you add productivity modules and such , but lets not complicate that . Some will make the copper wire onsite since you get 2 wire for 1 plate , so that cuts down on the required material supply , but you can still see how you need somewhere between 2 . 54 x as much input to what you get out .
