Thanks M. I know about the pin...mine moves a lot. But it's in place and the screw is tight. I just
ran it with nothing in the bowl and no beater and it's barely vibrating now. So, hopefully, it was the heavy dough from CI crescent roll recipe. It's the first time I've used it since moving and the mixer was crammed under the back seat.
It's an odd little recipe...you use the paddle the whole time rather than using the dough hook. And you only mix it for a short time so the gluten doesn't develop too much.
Result is nice, but they look so much like croissants that my brain is expecting croissant flakiness and this doesn't have that. it does have half a pound of butter in it.
