Red & Green Science Red Science needs Gears & Copper to craft. If your lanes are getting chronically unbalanced, consider putting in a proper 4 lane belt balancer, which splits products equally:Ī proper 4 lane belt balancer, (on iron), which splits products equally next to the space-saving solution (copper) which is a stop-gap solution when you have less space.Īnother example of splitting two products off the Main Bus: After the split off at lane 4, splitters allow movement of product to go all the way from lane 1 to lane 4, replenishing product on all lines. Therefore, use 3 splitters to divert resources back to that lane.Īrrows show direction of product movement. On a 4 belt line, you need to make sure the furthest belt from the split can feed into the edge you split from. On a two-belt line, (like steel or plastic), use a regular splitter. Balance After you split off to the side, you will need to balance the belts again to feed more back to the lane you just took from.
