Capable of retrieving multiple boxes cycling the chests content once. Instead of searching for box content or selecting a slot, it uses the pattern of key items and corresponding boxes in the chests, either replacing the key item with the corresponding box or leaving a gap, depending on the version used. If there's no match found, the chests won't be cycled. Suited for medium to high speed mergerDefinition: A Merger is a contraption that takes 2 boxes as input, and merges them into one. Mergers can work of mixed boxes, however most mergers assume that both boxes only contain one itemtype and are ofte...s and sorting sessions where you expect to merge a decent number of different item types.

Features

• Speed:
  • Pair preserving: ~150gtDefinition: Minecraft iteratively runs its processing code in a loop. One cycle of this loop is called a Tick or Gametick (gt). Gameticks are also used as the default measurement of time while working with re.../box (insertion) + ~900 gt (chest cycling and caching of pairs)
  • Ideal splitting: ~ 30 gt/box (check) + ~900 gt (chest cycling, pairs output) + ~24gt/box (non-matching boxes insertion)
• Capacity:
  • Pair preserving: 182 64-stackables + 25 16-stackables
  • Ideal splitting: 200 64 or 16-stackables

Considerations

• Can rarely produce empty or full boxes

Notes

Comes in 2 versions: pair preserving (slow) and ideal splitting (fast). **Both versions can rarely produce empty or full boxes, just filter them out or use the add-on provided for the pair preserving version if your mergers can't handle that. **

The pair preserving version has two variants: one uses a simple fader to stop chest cycling until the current queue of boxes is done inserting, while the other one uses a dropper counter to count the matches and doesn't allow chest cycling until a user-defined number of pairs is found. I recommend using the fader version.

Instructions

• Pair preserving: input previously whitelisted partials. If merger can accept new pairs, clock the pair request line at 24gt or higher. Set the threshold of pairs found to a reasonable number depending on your system and expected input (if using the dropper counter version). If there's "overflow", cycle it back to the input immediately or use an intermediate buffer.
• Ideal splitting: Input a batch of previously whitelisted partials that you know for sure don't have any duplicate item type. Dump all the output back into the splitterDefinition: A box splitter is a contraption that takes in a mixed box as input and unloads the box into single item-type boxes. These devices work by unloading a box using a variable filter. The variable filte.../cycvarDefinition: A cyclical variable sorter (cycvar) is a variable sorting device which takes in mixed boxes and outputs single-type boxes with minimum partial box output (ideal output). A cycvar works similarly to.../whatever device you're using.
