I have been getting chatter on the plunge of the Z-axis for a while now. I finally measured the slop and it is 0.007". When I reduce the weight on the z-axis by lifting the router support while it is plunging, then the chatter goes away.
I think this is causing the z-axis to miss steps, so now it has become an issue. Has anyone had this occur and how did you fix it?
Thanks!
