I have a 2001 TM-1 which has ran with only minor problems for 7 years, I'm now starting to experience chatter on some jobs, holes not profiled round and now hexs that are .002-.003 out from side to side. Do I need to call Haas out to tighten everything up or does it sound like I need to replace some parts. ( ball screws, etc.) Any suggestions would be greatly apprecicated.
