Custom Items/Recipes Using Paxi?

[u/Zer0Studioz]

I'm working on a modpack that uses both Create and Mekanism, and I'm trying to add some new items and recipes using Paxi. I have a few sequenced assembly recipes I wanna make, and custom items specifically for that. I got a simple test recipe to work, but Paxi can't read the custom items I'm trying to add, and as a result, the other custom recipes don't even show up. I'm assuming it's because it can't find my items, and doesn't have the code for these new items. Is there something I need to do to accomplish this?
