Making 4x mortar and pestle

I am making a new mortar and pestle.
it is 4x speed.
I have it all set up and linked.
when i go into the inv of my mortar and pestle it says item can only be crafted in the mortar and pestle!

The engrams are referencing the vanilla M&P they need to reference your custom one.

Can I do this while still making my mod compatible with other mods.
If so how?

Bump! Plz Help
