Turtle crafting...

turtle.craft()

while not turtle.detectDown() do
  turtle.down() -- get the turtle down to the ground.
end
turtle.up() -- to keep the turtle 1 block up in the air.

-- I got 2 pieces of log, and I want to craft a chest...
-- The log is in the first position in the turtles inventory
turtle.select(1)

  if i == 4 or i == 6 or i == 8 or then i = i + 1 end -- to get the crafting grid for a chest.
  if i ~= 8 then turtle.dropDown(8 - i) end -- drop the stuff below the turtle, unless it's on it's 8th run.
  if i ~= 1 then turtle.select(i) end -- select the correct slot (not on first run)
  if i ~= 8 then turtle.suckDown() end -- pick everything thats below up again, putting it in the expected slot.
end

-- [ ] [ ] [ ]

Since you have to use the same item to craft, when you craft logs into planks, you will have to place the planks down, select slot 1, pick it up, back to slot with plank stacks, place another log down, select slot 2, etc….
It's kind of annoying, but I hope you get the idea.

for i=1,3 do
  if i==2 then i=i+1 end
  print(i)
end

if gave you unexpectedsymbol because you said "or then"…. I think you was to make another or but cahnged your mind and forgot to take away that or. Do it… NOW

turtle.craft()

turtle.select(2) --select the 8 planks that we made.
turtle.drop() --drop them on the ground, or place them in a chest...Trust me this is easiest.
turtle.select(16) --selects the last slot. You following me, cameraman?
turtle.suck() --takes in all 8 planks into slot 16.

local function select(slot)
turtle.select(16) --select the stack of planks
turtle.placeDown() --places a plank down
turtle.select(slot) --selects our defined slot
turtle.digDown() --takes in one plank to defined slot
end

 
select(1) 
select(2) 
select(3) 
select(5) 
select(7) 
select(9) 
select(10) 
select(11)
turtle.craft()

You want to change your for loop to be for i = 1,8 do, but you're close. Initially, we want two logs to be crafted into 8 planks. so first:

 turtle.craft() 

Assuming we only had two logs in the turtle, we just bade 8 planks. Next:

 turtle.select(2) --select the 8 planks that we made. turtle.drop() --drop them on the ground, or place them in a chest...Trust me this is easiest. turtle.select(16) --selects the last slot. You following me, cameraman? turtle.suck() --takes in all 8 planks into slot 16. 

We now have all 8 blocks of wooden planks in slot 16. Now the fun can begin:

 local function select(slot) turtle.select(16) --select the stack of planks turtle.placeDown() --places a plank down turtle.select(slot) --selects our defined slot turtle.digDown() --takes in one plank to defined slot end 

Now that's our function, and now to implement it:

 select(1) select(2) select(3) select(5) select(7) select(9) select(10) select(11) turtle.craft() 

If all went correctly, you should now have one chest in your turtle's inventory.
