3016 97 ac fadal. powered up about a month before was used last. cs the machine and everything seemed normal. got a tool and when the spindle lowered over a tool the z- had
what seemed like a mechanical stuttering as it went down over the tool. still got to the tool no alarms. so jogged up and down .01 dial set and jogging smoothly no problems in either direction. but spinning the wheel fast down and stuttering would show. spin up no issues.
A little more background, the machine is on a phaseperfect. A few months ago I turned the rapids to 100% always had them set at 50%. and when the rapid on z happened the machine wasn't happy with it threw an alarm and the z position was off. cs the machine and seemed normal. It seemed to run normal after that just set back to 50% rapid, I figured a power issue and went on with life.
It was late but had a spare amp so I tried it and nothing changed. Oiled the z just to make sure it was a lubrication issue. the thrust bearing was replaced about 2 years ago, the tech checked the ballscrew and said it was fine, work had replaced it not even a year before deciding to replace the machine.
Anyone ever deal with this? trying to figure mechanical or electrical?
