Fast infine quarry

Recommended Posts

This is program for robot quarry. It uses a special pattern thanks to which it is up to 40% faster than the default dig.lua. The digging pattern also stretches into infinity, so if you equip the robot with a chunk loader upgrade you never have to worry about it again. The robot also remembers its position, so it the quarry can be easily resumed.

Source code and detailed explanation can be found on Gitlab: https://gitlab.com/vitSkalicky/oc-column-quarry


  1. Assemble a robot (see Robot requirements below).
  2. Set up power, tool supply, etc. (see Setup below).
  3. Place the robot and turn it on.
  4. Copy the minified program (squashed onto a single line).
  5. In the robot type "edit column_quarry.lua" and paste the program (by clicking the mouse wheel or using a keybind).
  6. Press ctrl+s to save the program and ctrl+w to exit editor.
  7. Run the program by typing "column_quarry". See Program options below.

Robot requirements



  • Computer case tier 2
  • CPU tier 1
  • 2x memory tier 1
  • EPPROM with Lua BIOS
  • Hard disk tier 1 with OpenOS installed*
  • Screen tier 1
  • Keyboard
  • Graphics card tier 1
  • Inventory controller upgrade
  • Inventory upgrade (more is better)
  • Hover upgrade **

*use a computer to install OpenOS on the disk before assembling the robot, or add a disk drive to the robot (like in the screenshot).

**If you use Hover upgrade tier 1, you must start mining at y < 64, otherwise the robot will get stuck in the air. If you use tier 2 you can mine at any height.

Also note that the minimal requirements robot does not have a Chunk loader upgrade, therefore you have to load the chunks externally (by using ChickenChunks chunk loader for example)



  • Computer case tier 3
  • CPU tier 1
  • 2x memory tier 1
  • EPPROM with Lua BIOS
  • Hard disk tier 1 with OpenOS installed*
  • Screen tier 1
  • Keyboard
  • Graphics card tier 1
  • Inventory controller upgrade
  • Chunkloader upgrade
  • Battery upgrade
  • Hover upgrade *
  • Inventory upgrade (more is better)
  • upgrade container for more inventory upgrades

*see Minimal requirements



  I P A A...

* R - Robot facing the top of schema
* C - Charger
* I - Items chest: the robot will put all mined blocks and resources here
* P - Pickaxes: robot will take fresh primary mining tools from here and will put used (almost broken) ones to a chest *on top of it*
* A - Additional tools: robot will take one tool from each chest in row. Almost broken ones will be put to a chest above. It will use these to try breaking blocks it cannot break with pickaxe (or the primary tool you supply it with). More on that later.
* The robot mines area to the top right of the schema

You can use any tool instead of pickaxe (such as a mining drill from IC2) and any inventory for items, not only chest. For example: the robot takes a charged mining drill from a batbox and it puts the discharged one into a hopper above the batbox, which pushes the discharged drill into the batbox for recharging.

The robot cannot mine cobwebs using a pickaxe (and other blocks from mods such as Magic bees hives). That's what additional tools are for. If a robot fails to mine a block using pickaxe, it will try to mine it using all the available additional tools.

The robot takes one additional tool from each chest to the right of the "pickaxe" chest. You can put as many chest you want - the robot counts how many chests there are.

  • The robot is facing away from the ender chest
  • The charger is powered by a creative capacitor bank and is turned on by a lever. You can use almost any type of power, but for some you will need a power converter.
  • Ender chest - mined resources will be put here
  • Iron chest - robot will take fresh primary mining tools (pickaxes) from here
  • Golden chest - used (almost broken) pickaxes will be put here
  • Copper chests - robot will take one additional tool from each. There are three, but you can have more, less or even none.
  • Diamond chest - used (almost broken) additional tools will be put here (to the one above the chest the tool was taken from)
  • Red area will be mined (continues infinitely)

Mid-game setup on Direwolf 1.12.2

setup screenshot

  • I use diamond drill (IC2) instead of pickaxe, because it can be recharged.
  • I also use a chainsaw (IC2)(rechargable too) for cobwebs and scoop for bee hives (Magic bees)
  • Power is supplied using a geothermal generator with an ender tank hooked up to my lava pump in the nether.
  • Ender chest sends mined items back to my base
  • The robot will take a charged drill and chainsaw from the batbox and put the used one into the hopper which pushes the tool back to the batbox to recharge.
  • The robot takes a charged drill first and then returns the used one, so I need two of them. One is being used by the robot and the other one is charging. (same for chainsaw)
  • Scoops cannot be easily repaired, so I just have a ton of them.
  • Don't forget to load the chunk with a spot loader and use a chunk loader upgrade in the robot.
  • I use the `--alwaysChangeTool` flag so that the robot recharges the drill whenever it drops off item.

End-game setup on Direwolf20 1.12.2

real setup 2

  • It is located in the Twilight forest dimension, because the y is lower in it (there is less stone to be mined before we get to the diamonds) and the solar cell works non-stop.
  • I use EnderIO solar cell with a capacitor for power.
  • There is another ender chest in my base which suck up items into my storage system and ore processing factory.
  • The robot mines with an Efficiency V, Fortune III, Unbreaking III, Mending diamond pickaxe. I also use 2 additional tools: sword for cobwebs and scoop for bee hives (from Magic bees mod). Both have Mending on them as well.
  • Tools are repaired in the EnderIO fluid tanks using liquid XP (tools have mending on them). I get the liquid XP from my mob farm by converting essence (Industrial foregoing) from mob crusher in fluid dictionary converter and pumping it through ender tank.
  • There are always 2 identical tools of the same kind: one is being used by the robot and the other one is waiting repaired to be exchanged for the almost broken one.
  • The robot takes a fresh tool from the fluid tank and puts the used tool into the hopper, which pushes it into the fluid tank, where it is repaired.

Program options


column_quarry [OPTIONS]...
column_quarry help


  • help - Displays help instead of starting the quarry.



 Resumes the quarry progress on the last mined column. Useful for example if the robot got stuck and you had to break it. Just place the robot at the starting point, use this option and it will continue where it was.


Where *n* is the side of the already mined area. The robot will continue mining **roughly** at the end of the entered area. Useful if replacing a lost robot. If you want to replace a robot you did not lose, it is better copy the state file (see *State saving*)


The robot will change its primary tool (pickaxe) every time it visits the start point, not only when it is almost broken. **Recommended when using a repairable tool** like in the example setups.

State saving

The robot saves its progress every time it finished mining a column into file named `column_quarry_state`. If you want to replace the robot, just copy the contents of this file onto the new robot and start the quarry on the new robot with the `--continue` option. I will continue, where the old robot finished.

Made a mistake and when it returned to drop off all the stuff, it didnt move so I quit the program and restarted it. Problem was that it was faced the wrong way, so it mined the item chest and charger and turned around and proceeded to dump all my items into the hole into the lava XD

I need a new charger lol

Also it likes to steal my armor XD
