Replicator - lostmyself8/Mekanism-MoreMachine GitHub Wiki
If you have already started the game once, you can open the "config" folder in the root directory of the game, and then find the "general.toml" file in the "MekanismMoreMachine" folder. Open it and you will see the following text:
#Custom Replicator Recipe
[replicator_recipes]
#The recipes added here will be added to the replicator. Write using modid:registeredName#amount, # followed by the amount(not null or zero) of UU matter consumed. For example:["minecraft:stone#10","mekanism:basic_bin#100"]
replicatorRecipe = []
This is where to add the recipe for the replicator.
According to the prompt, you can write down this text:
#Custom Replicator Recipe
[replicator_recipes]
#The recipes added here will be added to the replicator. Write using modid:registeredName#amount, # followed by the amount(not null or zero) of UU matter consumed. For example:["minecraft:stone#10","mekanism:basic_bin#100"]
replicatorRecipe = ["mekanism:basic_bin#100", "mekmm:w#1", "minecraft:stone#50", "minecraft:hopper#10", "mekanism:alloy_atomic#500"]
Then save and enter the game to view the recipe you added (if you have run JEI).
Careful you may have noticed that "mekmm:w#1" is not a correct ID, it is allowed to exist because it conforms to the preset format, but it will be ignored when read, so please confirm if your ID is spelled correctly before running it.
But if the text you write does not conform to the preset format, it will be deleted when the file is saved, so you don't need to worry about formatting errors.
