Hi All,
I have a strange problem with a Fanuc Controller. The Machine has just been through some major repairs. The gearbox was repaired and also the mainboard on the 31i was replaced. The issue that we have is that the machine does not have an automatic tool changer. So, they will have a M0 in the program. The machine will stop and change the tool manually and then press cycle start to continue with the program. The operator is pressing the cycle start button and nothing is happening. I notice that when the program is running it has 2 lines highlighted. One line has black writing with the background highlighted in Turquoise and then the line below it the writing is highlighted in blue. when the program stops then the M0 is highlighted in blue.
Does anyone here have an idea what is going on? I phoned Fanuc and they have no idea.
