Recenly bought this machine it has a Fanuc 6M Control and despite a few oil leaks it seems to be a decent Mill. I had been running a 1 tool program then switched to another program stored in memory which uses 5 tools. I have an alarm 84 flashing on the tool turrett with no next tool or spindel tool displayed on the front of the machine. However other than the beeping and flashing 84 the machine still operates perfectly fine. Any ideas???????????
