The Pattern Encoder is a block added by AE2 Stuff. It constantly consumes 1 AE/t and requires a network connection to function.
Patterns can be encoded by viewing the recipe of an item in NEI or JEI and then clicking the ? button. Unlike the ME Pattern Terminal, the Pattern Encoder does not require the components to be accessible by the network. The Pattern Encoder will only do crafting recipes, but not processing patterns. The Pattern Encoder retains its pattern when broken.
