Thanks
I ended up ordered a TDK-Lambda #RSEN-2030 yesterday from Mouser.
Should I stop worrying about the unusual noises the spindle makes. Other than the strange noise the spindle runs and cuts fine. The noise this spindle is making is not very loud,no where near as loud as the last spindle.
I am assuming since I already bumped the carrier frequency to 10 that there isn't any other parameters to change.

Good Choice of Filter and cost is ok as well

Does the spindle only make that sound when at the 12,000 RPM range
