i have an Elite Foreman 48x48 with stiffy rail, and notice the X axis ball screw looks bent as it wobbles up and down about half inch when in motion at about 200ipm the entire machine starts shaking around a bit, i guess my question is if tension needs to be set or is it possible to adjust it straight again, or do i need just replace it. my second issue is what looks like snipe on the right side when i surface anything it leave a distinct line that is cut lower than the rest, almost as if Z axis is lowered by a couple thousandths or so
Tram your Z axis. That should help.

Make sure the white bushing didn’t become loose.
