My 4 Side Quarry. Is the fastest I could build and is expandable
Inspiration from RagePlaysGames (video in Schematic Video)
FLAW: It does NOT dig the middle block. Use another machine to dig a 1×1 (or even a 3×3 so you can put some storage on it)
Note 1: It is advised to change the RedStone Link Codes
Note 2: You have to work on the Sequenced Gearshift for the machine to work as that is the component that will determine if the machine has to go UP or DOWN
