Yesterday my 1998 VF3 ran fine all day. Shut it off for a few hours. Fire it back up to run a different program. Start machining and get a error code X axis Z fault number 139. reset it then get 224. Read the repair manual, and it says check connector P1 on MOCON. Cleaned P1 and X axis servo board connector. Fired it up this morning, everything is fine. After 1/2 hour, change to a different program. Get the 224 error back. Shut the machine off. restart. Now it will not zero home, because of 103 error. When there is little work to do, everything is good. Get a big job, now I have problems. Any help would be sincerely appreciated Stephen
