How often should you run the auto tune?

[Moose]

The X and Z axis servos are not smooth and quiet like the Y.
You can feel vibration/buzz in the X and Z ball screws when idling.
The load meter display also shows that the X and Z are not steady like the Y.
The Y load meter is steady as a rock when idling.
Z will sometimes release power "Idling too High"
Since I purchased this mill I have not performed an auto tune, Should I?

You don't tell us much about your setup. Which control, what servos (make and model) and you always need to post a report. Lots of information in it

For most servos, the kind of tuning to fix the above is on the servo drive itself (using the manufacturer software), not in centroid.
It sounds like the response level of whatever PID loop they use is too high.

Who makes the servos?

If it's a Centroid All in One DC, then it has the drives.
Again, he does not give enough information when asked.
We can't guess...

Yeah, good point.
We need a report to get anywhere.

I am assuming this is an Allin1DC system based on your profile. Compare your servo motors to the chart in the ALLin1DC install manual to check the PID settings, then try running auto tune. Save a report first as a backup.
