Applied Voltex is a small Applied Energistics 2 addon. It does two things AE2 can't do on its own: craft patterns instantly, and autocraft Avaritia.
A standalone assembler that resolves a crafting pattern with no delay, instead of waiting on the slow Molecular Assembler. Put it next to a Pattern Provider, give it the pattern, and it crafts in one go. Handy for the recipes you make a lot and don't want to sit through.
AE2 won't autocraft anything bigger than 3x3 by design, so Avaritia's 9x9 Extreme Crafting normally can't go through the ME system. This block runs those recipes as regular AE2 processing patterns. Encode the recipe, request it, and the 9x9 result builds like any other autocraft.
Encoding 9x9 recipes by hand is tedious. The Encoder reads Avaritia's recipes and turns them into AE2 patterns for you, with a search box to find what you need.
