OR signal-A = signal-B (green)   OR starts a new group
OUT signal-check = 1             output a fixed 1
OUT iron-plate (epic) = input    output the input counts
OUT signal-A = input FROM red    count one wire only

What this combinator does
Blueprint string
  • Import with the blueprint import button (or Ctrl+V after copying in game).
  • Paste an existing decider blueprint above to edit it as text.
  • A signal reads both wires unless you limit it with (red) or (green).
  • Outputs send either the input count or a fixed 1 per signal.
  • ELSE outputs need Factorio 2.1; everything else works on 2.0 too.
