I have a Fanuc robot I am fighting with a frozen teach pendant. Some fat fingered line 8 into this program and every time the machine gets to this line of code it freezes the pendant. there is no error, the robot keeps moving and welding but the moment you try to edit the program (to delete the line) it freezes the pendant and you can't do anything until you cold start the robot. I've tried switching pendants but the same thing happens. There's also "???" at the end of the line and I don't know what these means or how's its possible. How can you delete this line so it stops freezing the pendant?
Thank you.
