This one lays torches but requires two scripts, a setup and a mine program. It's much more complicated and not worth the time IMO.

===== Farming =====
From ChatGPT
<code>-- This turtle will plant and harvest a 20 by 20 area

-- First, define the size of the area
local area_width = 20
local area_length = 20

-- Next, move the turtle to the starting position
-- (assume that the turtle is facing the correct direction)
turtle.forward()

-- Now, loop through the rows
for i=1,area_length do
  -- Plant seeds on this row
  for j=1,area_width do
    turtle.placeDown()
    turtle.forward()
  end

  -- Move the turtle back to the beginning of the row
  for j=1,area_width do
    turtle.back()
  end

  -- Move the turtle to the next row
  turtle.turnRight()
  turtle.forward()
  turtle.turnRight()
end

-- Now, the turtle is at the end of the last row
-- Move it back to the starting position
for i=1,area_length do
  turtle.back()
end
turtle.turnLeft()
for i=1,area_width do
  turtle.back()
end
turtle.turnLeft()

-- The turtle is now back at the starting position

turtle.sleep(600) -- sleep for 10 minutes

-- Loop through the rows again to harvest the crops
for i=1,area_length do
  -- Harvest the crops on this row
  for j=1,area_width do
    turtle.digDown()
    turtle.forward()
  end

  -- Move the turtle back to the beginning of the row
  for j=1,area_width do
    turtle.back()
  end

  -- Move the turtle to the next row
  turtle.turnRight()
  turtle.forward()
  turtle.turnRight()
end

-- Now, the turtle is at the end of the last row
-- Move it back to the starting position
for i=1,area_length do
  turtle.back()
end
turtle.turnLeft()
for i=1,area_width do
  turtle.back()
end
turtle.turnLeft()

-- Done!
</code>
This script will plant seeds in a 20 by 20 area and then return to the starting position to harvest the crops. Note that this script assumes that the turtle has enough seeds and fuel to complete the task, and that it is facing the correct direction when it starts.


===== Mining =====

ChatGPT mining script
<code>
-- Ask the user for the size of the mine
print("What size should the mine be?")
local size = tonumber(read())

-- Check that the input is valid
if not size or size <= 0 then
  print("Invalid size")
  return
end

-- Define a function to dig down to bedrock
local function digDown()
  while turtle.detectDown() do
    turtle.digDown()
  end
  turtle.down()
end

-- Define a function to return to the starting point
local function returnToStart()
  -- Face the turtle towards the starting point
  turtle.turnLeft()
  turtle.turnLeft()
  -- Move back to the starting point
  for i = 1, size - 1 do
    turtle.forward()
  end
  -- Drop off items
  for i = 1, 16 do
    turtle.select(i)
    turtle.drop()
  end
  -- Keep 1 stack of coal
  turtle.select(1)
  turtle.transferTo(16, 64)
  -- Refuel with coal
  turtle.select(16)
  turtle.refuel()
end

-- Pull a stack of coal from the chest
turtle.select(1)
turtle.suck(64)

-- Dig out the mine
for i = 1, size do
  for j = 1, size do
    -- Dig out a layer of the mine
    for k = 1, size do
      -- Check if the turtle's inventory is full
      if turtle.getItemCount(16) > 0 then
        returnToStart() -- Return to starting point and drop off items
      end
      -- Dig out a block
      turtle.dig()
      turtle.forward()
    end
    -- Move to the next layer
    if j < size then
      if j % 2 == 0 then
        turtle.turnRight()
        turtle.dig()
        turtle.forward()
        turtle.turnRight()
      else
        turtle.turnLeft()
        turtle.dig()
        turtle.forward()
        turtle.turnLeft()
      end
    end
  end
  -- Move to the next layer
  if i < size then
    turtle.turnLeft()
    turtle.dig()
    turtle.forward()
    turtle.turnLeft()
  end
  digDown() -- Dig down to bedrock
end

returnToStart() -- Return to starting point and drop off items

-- Resume mining
for i = 1, size do
  for j = 1, size do
    -- Dig out a layer of the mine
    for k = 1, size do
      -- Check if the turtle's inventory is full
      if turtle.getItemCount(16) > 0 then
        returnToStart() -- Return to starting point and drop off items
      end
      -- Dig out a block
      turtle.dig()
      turtle.forward()
    end
    -- Move to the next layer
    if j < size then
      if j % 2 == 0 then
        turtle.turnRight()
        turtle.dig()
        turtle.forward()
        turtle.turnRight()
      else
        turtle.turnLeft()
        turtle.dig()
        turtle.forward()
        turtle.turnLeft()
      end
    end
  end
  -- Move to the next layer
  if i < size then
    turtle.turnLeft()
    turtle.dig()
    turtle.forward()
    turtle.turnLeft()
  end
  digDown() -- Dig down to bedrock
end
</code>
Here's how the updated script works:

  *     The script defines a new returnToStart() function that the turtle will use to return to its starting point, drop off its items, and pull a stack of coal from a chest.
  *     Inside the dig out a layer of the mine loop, the script checks whether the turtle's inventory is full using the getItemCount() function. If the turtle's inventory is full, it calls the returnToStart() function to return to the starting point and drop off its items.
  *     After the mining is complete, the script calls the returnToStart() function again to drop off any remaining items.
  *     Inside the returnToStart() function, the turtle first turns around to face the starting point, then moves back to the starting point using a for loop. It then uses another for loop to drop off all items in its inventory.
  *     Finally, the returnToStart() function selects the first slot in the turtle's inventory (assumed to contain coal) and uses the suck() function to pull a stack of 64 coal from a chest.
