Loose Router Bracket

Good day all,
I have the Xcarve 750 using a DeWalt 611 Router. I have noted my work getting a little sloppy and then noticed that the top of the router carriage is a little loose, maybe a couple of hundreds. I have also noted that on curved cuts the machine emits a low pitched whine when the x axis is moving in conjunction with the y axis. so I have concluded that either I need new rollers for the Z axis rollers or is there an adjustment that can be made to “tighten” this up? thanks in advance for your responses.

First things to check are that all of your V-wheels are tightened down (securing bolts and nylon lock nuts), then that your V-wheel spacing is adequately set (via the eccentric nuts).

Thank you, that did the trick. Best wishes
