This script is part of a series of 5 scripts intended for CPU's to run an automated advanced furnace.
Besides the 5 CPU, this setup uses 2 dials (one for setting which type of ingot you'd like to create (Standard Metal, Alloy or Super Alloy) and one for selecting specifically which type of ingot to create. Furthermore the setup uses an itemhash display to show the ingot being created, the itemhash is read of the settings display CPU.

The scripts should be pretty self explanatory.
