I recently purchased a used Kitamura My Center 1 milling machine. It has a Fanuc O-M control on it. When I try to transfer the program from the pc to the machine it doesn't show it was received. My friends in the industry say it could be the chip that is the problem. We have all the other transfer data and setting set correctly as far as we know like baud rate bits parity etc... any help would be appreciated.
