Machine noise/vibration

[Oregonian1a]

I have been using my XT for a few weeks now. Certain fills can cause the machine to be significantly louder than others. Some of this I understand, and it appears that fills that are closely aligned with either the X or Y axis may produce more "rattle".

Are there any settings that can be adjusted to help mitigate the vibration of the louder sections of the design? Stitch length maybe?
