Turtle Paste

-- This program will works only with a Minium Stone provided in the first slot of a crafty turtle
-- exactly in this setup http://tinypic.com/r/16c71w8/6
-- The stone never worns out, you can stress the crafty placing blaze powders in every slot while it      -- works, no matter. Only don't put blaze powder in slot 16 or they'll return to macerator!
-- Note: this program will become obsolete when they'll fix the turtle.drop() and turtle.suck() commands
-- that afflicts CC 1.5, but will work anyway.
-- WARNING: You have to put AT LEAST 10 powders in crafty's inventory or in the chest below.

tWait = 5 -- A higher value will slow down the turtle, just for th sake of your little generator
goodstack = 30 -- Numbers of blaze that the turtle will TRY to process in one load.
               -- It needs at least 10, but will go faster with higher stacks: raise this value and
               -- fill the chest below with 4 stacks (depending on macerator upgrades) for top speed.
