What is it used for?
These Multi-block crafters are what needed to do any sort of auto crafting in your ME system.
How do I build one?
The Multi-block has a lot of flexibility on how you build it but a few parameters are:
- It has to in a rectangular/square shape to autocomplete
- Has to have at least 1 Co-Processor and 1 Crafting Storage
- ‘Crafting Units’ are not necessarily needed but can be added to be able to see what each individual Multi-block is working on.

The minimum size^

My recommendation^
What are bytes and how many Multi-blocks should I have?
With ME auto crafting every time you are auto crafting something whether it be 1000 doors or a RFTools Powercell they use a certain amount of bytes to craft, depending on the complexity it may require more or fewer bytes. For example, crafting 1 door won’t take up many bytes but 1000 will take a lot more. Depending on the number of different crafts your going to do the more multi-blocks will be needed. So if you are making 20 signs but at the same time you wanna also craft 20 Dense cables then you are going to need more than 1 of these Multi-blocks.
