There's one problem with iron oxide remelting that pyanodon stubbornly refuses to notice - now it is unprofitable to send iron oxide to iron slime in iron chain bcu its more profitble to smelt it directly - 2 iron oxide to 1 plate
I suggest to change it to 10 iron oxide to 1 iron plate bcuz in the begining there 10 raw iron ore smelting to only 1 iron plate
1 iron plate can give us 2 iron oxide
So we need to overwrite recipe for iron oxide smelting

Mm....i understand i m on it

Please send me a blueprint with the begonnig chain for testing :)

I'm not using blueprints - but i can test iron chain using creative mode and then calculating all with Helmod

Ok thanks
