My Chinese spindle had quite a high pitched noise when I first got it running. I contacted the seller and he told me that it will quiet down with some run time. I ran a 12 hour 3D carve and sure enough, it runs much quieter now. Now that I've got all the bugs worked out I'm very happy with my 2.2kw air cooled spindle.

Does your software turn the spindle on-off and set spindle speed? Mine does but I still need to push the Start button before I run my first cut file.
