Help with simple woodcutter

I want my mining turtle to cut down a tree, I wrote this but it won't move or say anything.

function cut()
turtle.detectUp() then
turtle.digUp()
turtle.up()
cut()
end
end

You never call the function from outside. Regardless, the behavior of your function would not be what you expect. It would just continue to dig up until it hit the block limit and/or the loop limit. Here's a better system:

for i=1,16 do --#First off, select a slot that has nothing in it so that we can compare the logs as we dig upwards
  if turtle.getItemCount(i) == 0 then
    turtle.select(i) --#Accidentally forgot the i
    break
  end
end

local function tree()
  turtle.dig()
  turtle.forward() --#Position ourselves under the tree
  while turtle.compareUp() do --#This compares the log that we dug getting positioned to the log directly above the turtle.
    --#This loop will end as soon as the block above the turtle no longer matches the log in its inventory
    turtle.digUp()
    turtle.up()
  end
  while turtle.down() do end --#While the turtle can go down it will continue to do so
end

tree() --#Don't forget to actually call the function

I tried that and it says turtle:18: Expected Number

Oops. I updated my OP. Just forgot to put the i variable into turtle.select on line 3.

And that explains why I couldn't find the bug, you were too fast for me bubba

you are using

turtle.detectUp() then

when you should be using

 if turtle.detectUp() then

also calling your function within your function will cause a stack error.
