Hi everyone,
I sometimes run long programs using DNC on my Fadal VMC15 for an hour or more. The communication link seems to fail randomly, 1-4 times per hour. The communication link is a via a serial cable (I think it's shielded) approx 80 ft. long.
When it does fail, the last line of code that was transferred stays on the screen, and the machine just stands there, spindle and coolant running.
This failure occurs using any baud rate from 9600-38000.
What is causing this problem?
-Thanks
