Help Please with Industrial grinder

I am making a new industrial grinder to replace someone else’s mod that disappeared. I am able to place my grinder, the items I want to craft (gunpowder, chitin paste, spark powder, and narcotics) all show up inside of the grinder, and they turn light blue when I place the resources into it. But they can’t be crafted. I can still craft thatch and flint, but the others can not be crafted for some reason. Im missing something, I just cannot figure out what it is. any help is appreciated.

Thank you in advance!

You need to check the various blueprints that are associated with your grinder… doing a reference view will see the ones that are linked to it.

Most likely the PrimalInventory you are referencing doesn’t have the items linked to it’s crafting… check out the Default Inventory Items and Default Engrams expand boxes. Take a look at the Fabricator version for an idea.

Could you please look at my PrimalInventory file and tell me where to connect it to crafting ?
