Hi. Sorry to bother again but I need a bit more help. I have added to the turtle code a section that checks if the chests are full and if so sends a signal to the controller computer. The code I believe is working fine except that I get an error: rednet :47: vm error: java.lang.ArrayIndexOutOfBoundsException

This is the code I am using for the checks
function isCoal()
    if turtle.suck(1) == false then
        rednet.send(25, "cFalse")
        rednet.send(25, "cTrue")

I use a similar code to check the torches chest. The idea behind calling the function again is that the turtle will keep checking the chest until the chest gets restocked. This prevents the turtle from continuing the mining until it has the required items to do so. I think that java is giving this error because it thinks that the turtle is caught in an infinite loop.

Could you suggest a course of action or a fix for this.

Close. Actually, it's giving you this error because you have more than 256 function calls before any of them end.

TL;DR: Making a function call itself makes this error occur. Instead, use a loop.
local function isCoal()
  while not turtle.suck(1) do
    rednet.send( 25, "cFalse" )
  rednet.send( 25, "cTrue" )

I believe this will do what you want, while not causing a stack overflow nor a too long without yielding error.
