How a sorter works

Items flow along a line of hoppers. Under each one, a filter hopper holds the item you want to catch. A comparator reads it, and when a matching item arrives, it lets that item fall into the chest below.

Setting up the filter

• Put 41 of the item you want to sort in the first slot of the filter hopper.
• Put 1 renamed dummy item in each of the other 4 slots so nothing else fits.
• The comparator now reads 2. One more matching item pushes it to 3 and unlocks the hopper below.
