Just tried out my Shapeoko Pro for the first time. Great machine but…when I run the router at full speed it sounds like a screaming banshee. My old Makita router was so much quieter. Time to go back to using ear protection.
Even with a quiet machine one should still wear hearing protection unless one has an enclosure which is incredibly effective.
If the bearings seem to be an issue, let us know at support@carbide3d.com and we’ll do our best to get them sorted out.

Also, I never run my Makita router at it’s maximum RPM. If you have not, I would spend some time learning about speeds/feeds.

So every job is different but my Dewalt seldom is run at more than 3 on the speed dial and a lot of times at 2. But I do mostly cut wood so you have not said what you are cutting to have your RPM up all the way.

I wasn’t cutting anything, just checking out the router. 
Unless you are running insane feeds you will never need to run it full blast. Most carbide end mills are happy below 24k rpm unless you drop big money on a highly balanced Datron or other high end mill.
If you have the room and can build an enclosure it’s a good idea to do so. look at others setups and build what suits your needs best and always use hearing protection. I have tinnitus and can tell you first hand it will drive you mad so protect your hearing.

I’m still not happy with the carbide 3d router. Still very noisy and sounds like the bearings are rattling. Plus the speed seems to vary while running even without a load. Think i’m just going to purchase a Makita RT701C router and replace it. I can cut the power cord to the router near the mount and install a plug and socket so i can just plug the router in without having to take all the drag chains off and restring the power cord. This will also make it simple if i ever have to replace or remove the router.
