its a quarry/miner for mining chunks out (expandable by putting more gantry shafts/drills)

!!BEWARE only one can be used every 300 blocks (varies by the redstone links max range def: 256 blocks)!!

Setup:

- align the pillars to the inner corners of the chunk borders

- 3 pillars of smooth stone marks the default mining range(16x16)

- set the max desired mining depth with a threshold switch that can be found on the rope pulley

- it has a windmill for power just have to activate it with a r-click

- it has 3 levers for controlling it:

- top(1st) lever stops the mining head after it finished its round

- mid(2nd) lever stops the mining head after it finished its round then pulls the head back to the surface

- bottom left(3th) lever blocks the miner to re-start after it finished (recommended to enable)

Extras:

- can be expanded with gantry shaft and moving the redstone contacts to the end of the gantry

or drills can be used

- can be transported with a minecart contraption maker (alredy glued everthing so it can be easly picked up and moved)
