I'm in the process of taking the saddle off now and cleaning all the oil lines and the liners. Ive got the saddle off and there was some junk in the oil grooves that were machined into the liner. The ballscrew and nut are tight. There is no noticeable play when I move it by hand. I will check with an indicator later on today. Im beginning to think that this whole issue may be slip stick since I definitely have some oiling issues going on both the table and saddle.
