Hey folks! I need some help on how to get a program into my controller. Okuma mill with an OSP5020M control. I've got a portable DNC box and the RS232 cable is hooked up. I've been able to send a program to the DNC but not from the DNC to the machine. I'm not sure I'm talking to it correctly. I've tried PIP read .. nothing .. I've tried PIP CN0 .. nothing. How do I do it? What is it looking for? I have a $xxxx.min% at the beginning of the program and a % at the end. It's driving me crazy.
