Need help please. I have a 1998 Haas VF3. Last 8 months, would get a 234 code, spindle cable fault. If I reset, would go away for a day or a month. Now comes on after machine is powered up, when I start to run a program. I also occasional get a 235, Z axis fault. I also now get a 112, interrupt alarm. This alarm you cannot reset. The machine has to be powered off then on to go away. Any suggestions please.
