Is there a question in there someplace? I must have missed it.
Are you saying that none of your other machines have Fanuc controls?
How do you currently transfer a program to another machine? Do you use a floppy disk? Do you use a USB thumb drive? Do you use compact flash card? Do you have the machines wired on a network? Do you use a RS-232 cable? What is the software you use for the other machines called? Do you know how to set baud rate and parity for RS-232 communication?
