Final noob question I promise: I can't for the life of me figure out how to make iron in the EBF. I've tried connecting oxygen to the input hatch, the EBF itself, putting iron in the input hatch and the gui, to no avail. Do I have to use oxygen cells or does it not take fluid oxygen?
What do you mean : "make iron" ? Do you mean "make steel from iron", or "cook iron ore for 3x gain" ?
As for 'hatch', those are for liquids only. Oxygen uses hatches and you can use the liquid/piped oxygen, correct. However, you need 1 Input Bus and 1 Output Bus for items like steel, iron, etc.,.
Also, can you do any other recipes in the EBF, such as silicon ingots or aluminum ?
