This is a plugin that was created, because other, similar projects weren't good enough for crafting honey bottles into honey blocks: the glass bottles would get lost.
To create an automatic crafting station, use a crafting table, place an item frame onto it. Inside the item frame, set the result item you want to be crafted.
For inputs, place hoppers looking towards (into) the crafting table.
For outputs, you need a chest on any side of the crafting table.
Then power the crafting table with a direct redstone signal. The redstone component needs to be a neighbor of the crafting table.
A visible connection is not required. On the raising flag, the crafting table will try to complete your recipe.
Can this project become more popular than my old Falling Trees plugin? 😁
