Big Automatic Quarry, i took the schematic from Blazed ( https://createmod.com/author/blazed ) and made some tweaks to make it able to dig a much bigger area. READ CAREFULLY the quarry is easy to break, TO TURN IT ON: rigth click the bearing n°1, then right click the bearing n°2 at this point the drills and the chest should start spinning, finally right click the bearing n°3 now it should start going down 1 block every time the redstone contacts touch. TO STOP IT: right click the bearing at the bottom of the quarry (n°2 from the image to how to turn it on). TO BRING IT BACK UP: make sure it no longer spins at the bottom and the you can bring it back up by 1 block by simply right clicking the hand crank or you can bring it all the way up by clicking on the lever BUT once it's all the way up click the lever again or it won't go back down . it's a big machine so expect to have a bit of lag. the material list is quite big but in the end worth it. If you have suggestions or problems you can contact me at [email protected]. Thanks for downloading !

Edit: i accidentally rated my schematic 0/5, it was me not a random guy
