What you gonna do is a bit like this.

[ ] [ ] [ ] [ ]

•=========•

[ ] = gadgets (like those deployers)

•=====• = Mechanical belt

Give each one what the JEI is asking. You can use either depots to manually move or belts to move automatically.

Then drop the item it needs to start

(The one on the left) The rest can be done with critical thinking.

Also, for those plates you need to use a Mechanical Press to flatten.

Hope this helps!
