We have a KOMO 512 mach 1 with a Fanuc 210i controller
The scrolling G code is gone from the screen and the controller locks up at random times, Fanuc says this might be the PC board and wants 3100+ for the part with no guaranty that this will fix our issues. I replaced the hard drive yesterday, no joy. Any insight into this would be very helpful.
It semms to be a RAM memory problem, I suggest you replace the SRAM board first, to do that you must backup all programs and parameters. You'll have to have the new board to replace and test.
