Extended Crafting allows you easily add your own Combination Crafting recipes using CraftTweaker. Here's how you do it.
Adding a recipe
mods.extendedcrafting.CombinationCrafting.addRecipe(name, <output>, powerCost, [inputs]); mods.extendedcrafting.CombinationCrafting.addRecipe(name, <output>, powerCost, powerRate, [inputs]);
name: A unique name for this recipe. Must be all lower case and have no spaces.
output: The output item for this recipe.
powerCost: The amount of FE required to craft this recipe.
powerRate: (optional) The rate the recipe should consume FE. powerCost / powerRate = the number of ticks required to craft the recipe. If this isn't defined it will use the default value defined in the config.
inputs: An array of 1-49 items. The first item is the item that goes on the Crafting Core, and the rest go on the pedestals.
mods.extendedcrafting.CombinationCrafting.addRecipe("test", <item:minecraft:stick> * 10, 10000, 100, [<item:minecraft:diamond>, <tag:forge:ingots/iron>, <item:minecraft:stick>]);
output: The item to remove all recipes for.
