With processing patterns, the Crafter has to face the correct input side of the machine.
A Crafter can be chained by letting them face each other.
This is useful when connecting a Crafter to a single machine. When you run out of slots in your first Crafter, the one facing the machine, you can put another Crafter behind the first Crafter to get additional Pattern slots.
The Crafter has 4 modes:
- Ignore redstone signal (default)
- Redstone signal unlocks autocrafting
- Redstone signal locks autocrafting
- Redstone pulse inserts next set
The (un)locking mechanism is used to block the Crafter, so it can’t insert items or fluids into the connected inventory.
“Blocking mode” can be achieved with the “Redstone pulse inserts next set” mode.
See Locking and unlocking for more details.
