I have a Fagor 8055 control on a 5-axis router and we are having a few issues that we would like help on where to start trouble-shooting. It will seem to jump a line while executing a program and/or run-off. Example could be running at line 100 and jump to line 200 cutting through anything between those two points. Other issues are it will be running and half the code on the screen is gone. It just is blank and the machine stops with spindle running. Both of these issues are random. You could clear both errors out and run several hours or days even before it occurring again. We have had a few technicians look at the machine and they have replaced hardware and wiring with no success. We do not want to through more money at it at this point until we can try and better pinpoint the root cause.
