My Shops 14 month old LB4000 took a pretty hard crash a month or so ago. I don't run her that often, but I've been on it all week this week, and have noticed the the Z axis is starting to sound more like our 15+ year old MX45 mills. We have an 8 year old Captain that is quitter when positioning the turret. Is it normal for a machine as new as she is to be making so much noise when rapiding in Z, or is this yet another call we need to make to the techs to get her back in ship shape after the crash?
