Features:
Scalable Design: Easily expandable by tiling the input blocks vertically.
Starter Friendly: You can delete the bottom two rows of EM Plants to reduce cost and power usage for a smaller initial setup.
How to Expand: To increase throughput, you need to saturate the Uncommon tier.
Select the "Input Block": Copy the 6 leftmost EM Plants (producing Common/Uncommon modules) along with the 1-2 beaconed EM plants furthest to the left.
Paste Below: Align the underground belts with the existing setup.
Scale Up: Once you have enough input blocks to create a surplus of Rare items, you can copy-paste an additional Rare-tier EM Plant to consume the overflow. Also, add a splitter to sort items of higher rarity towards the upper block.
