Hey There all,

I am (still) fairly new to LUA and I created a auto smelter for wireless turtles.

The turtle can build you the smelter up to 15 furnaces.
The turtle will send everything he does to a server (computer with a wireless modem and monitors) but says nothing in the turtle-terminal itself. (just to keep it clean. I don't like crowded terminals :)/> )
I recommend a computer with wireless modem and 8 monitors. This should be enough I think.

SpoilerThere will be 3 chests from bottom to top
Bottom = smelted ores and resources
Middle chest = coal (not coalblocks)
Top chest = ores and stuff that needs to be smelted.

when placing all the ores and stuff in the furnaces, he will not smelt more than 8 items per furnace with 1 coal.
I chose for this way because of the timing to get the ores back out of the furnaces. (This will take exactly 80 seconds for 8 items and 1 coal.)



Server files: pastebin get uEYDLq1n Server (just some random standard snippet for rednet ;)/> )
Turtle files: pastebin get 4Jf4Bjb2 Cook



here are some example screenshots of the build:

follow the instructions on screen (after creating a server with monitors) to let the turtle build the structure.
My advise is to do this above grounds, because the turtle will put furnaces in a line (from 1 to 15, chosen by you)
Also a reason why you absolutely need a monitor, is so this can be used on servers with a little grind. Mine up a lot of stuff yourself, then build the computer, wireless modem and monitors and then build the turtle, since you can't see any code on the turtle with this script ;)/> (I chose for this)

if you should have build this structure elsewhere in the world, you can place the Turtle in front of the bottom chest and after the instructions screen, press 2.
he will count how many furnaces there are in the structure (Keep in mind that you can place as much as you want…. but the turtle only has 15 slots for ores to smelt because Slot 1 is used for coal)

I hope you guys like the effort and the script :)/>
Again, I am still a noob in LUA scripting, so if you should take a look at the script, there could be a lot of code that is a little messy.

Here is my script for the turtle, so you can see the messyness LOL
