My machine just started to chatter a great deal but only when cutting in the Y direction. The rest are fine. It is particularly bad when going toward the back of the machine and minor when moving toward the run of the machine. I have the router as far down in the clamping bracket as it can go. Not sure if this makes any difference.
I would appreciate any ideas as to what may be going on. Because of this the bottoms of my cutouts look like a lake on a windy day but only on the left and right sides of the pockets. Worse on the right side of course.
