Control is a fanuc 3m. It will consistently punch programs from the control to the PC, but will not go the other way. Is there a way to check the RS232 port on the CNC? I have a lighted 9 pin box between the pc and the CNC everything looks good there. I shows data coming in when punching, and data going out after I hit input on the control (I have "wait for XON" enabled). The control however just blinks LSK and never registars a new program number or writes the program to memeory. There are no alarms generated. I also know that the cable form the PC to the CNC is good. Can anyone suggest a repair company? I may have to send the main board off to be repaired.
