Just a bit of a teaching side note... read if you wish

Spoiler

The lines all over the place that you have as following:

if turtle.down() == true then
while forward() == false do

for ease of reading can become this:

if turtle.down() then
while not forward() do

as these functions return a boolean variable, the if statement is able to 'evaluate' its conditional from that returned value... not reverses what the boolean is, so if its true then it becomes false, if its false it becomes true... not can also be used to toggle a boolean variable

var = not var

instead of dooing

if var then
  var = false
else
var = true
end

other notable things is say we want a turtle (non-mining) to move down if there is something in-front of it and nothing below it or else just fail and sit there, we could do this

if not turtle.forward() and not turtle.detectDown() then
  turtle.down()
else
  error()
end

but instead we can do this

if not ( turtle.forward() and turtle.detectDown() ) then
  turtle.down()
else
  error()
end

its not a big change, but its less not's all over the place confusing you when its read... the way is it works is it evaluates the brackets first by using the following binary logic

true and true = true
true and false = false
false and true = false
false and false = false

with one change we can have this move down if there is something in-front of it, or nothing below it... we simply change the and to an or... that uses the following binary logic

true or true = true
true or false = true
false or true = true
false or false = false

Hope this helps you with making better logics in your programs

Only ~50 posts today :/ average is about 80... my peak is ~180... And thanx for you kind words I don't know everything though thats my genius friend...

Yeah i can definitely make those changes. I thought i tried that at the beginning and got an error, thought lua was a little weird that way. I guess not! After this problem is fixed I don't think anything else will need to be added

Sometimes errors can arise when doing it with variables since Lua allows any data type in a variable. however if you always make sure you store a boolean in the variable you won't get any errors... unless your logic is wrong...

It places one of the cobblestone from the slot, drops the rest, and then picks it back up. Essentially dropping all unwanted cobblestone by sacrificing a slot. It's where this problem starts actually

you could always do this

turtle.select( 1 )
turtle.drop( turtle.getItemCount( 1 ) - 1 )

This would drop all except for 1

Oh and I realize I had tried something like this before. For some reason, passing a parameter to turtle.drop() is bugged and ends up not dropping anything at all. At least in 1.33. Is it fixed in the later versions?

Yup, I've never had that error on the most rescent versions. You should change your current pack, FTB (Feed The Beast) is way better thy tekkit and is up to date. I assume you're using tekkit

That definitely sounds like a Bukkit issue to me!
