Hi, hoping someone can help me out.

I created a program on Mastercam X2 and used a generic Fanuc post processor to create an NC file. I put the .NC file on a floppy, and transferred it to the computer that is attached to my cnc machine.

I have an Emco Maier PC50 milling machine that is controlled by a pc. The name of the program that controls the machine is WinNc., version 3.1. The controller is Fanuc OM. I think it's a program meant to emulate the Fanuc controller, using a PC and a keyboard.

I open up the WinNC program in Windows Explorer, and drop the .NC file in the Prog. Folder from my :A drive.
I open the NC control program (WinNC) and try to load the .NC program into the controller to run the program.

For some reason, the program is not recognizing the .NC program I loaded into the program file.

Any idea what I am doing wrong? Wrong post processor? Or do I need to save the .NC file using a different file extension? Any help is appreciated. Thanks in advance.
