I guess the ladies have to stay out of this oneOriginally Posted by Alex S.A
Alex, If I understand correctly your data transmission is being interupted when you down load from PC to CNC??
If so make sure you have the correct cable, with either the handshake lines connected or jumpered out in the connectors at both ends, also many CNC communication systems use Software handshake (XON XOFF), if so this should be enabled if necessary.
Check the ESAB manual for the requirements. Have you used this communication program with this machine in the past? Does the CNC control give an error code?
