Mine any shape with all 4 quadrants, and output an even space belt of 4 pins ({P-P-P-P-}). It takes ~90 seconds to prime, and then about another 30 sec to warm up to full speed.
Benefits/Features:
-Converts shapes to pins at a 4:3 ratio (max efficiency). 4 miners (3 extensions each) for 1 space belt.
-No post-processing needed => best platform point efficiency possible.
-Efficient pin production is denser to transport via train than transporting equivalent shapes/fluids.
-Supports normal/hard/insane mode.
-No manual fiddling with priming/initiating it. Just throw it down, and it will automatically start itself. Also no sourcing of external nonsense to kick it off.
-Does not need crystallizer unlock.
-Output is automatically evenly distributed across 12 lanes of a space belt.
Limitations:
-Requires unlocking wires, gates, and 3rd floor.
-All lanes must be pulled from evenly to prevent it from backing up. If not going to a train, you may need a priority overflow to void block.
