Chatter X Axis

Have recently developed some small chatter on my X axis.
The chatter only happen when moving from right to left, left to right is smooth. Y and Z axis are smooth.
Also using Dewalt 611.

Think it might be the Vwheels?

The search function is your friend when it comes to this issue. I can verify that from experience.

Most x axis chatter comes from one of two sources.

Flex in your y axis rails when cutting in +/- X-axis

Flex in your z axis slide assembly.

Both can be remedied with upgrades to stiffen the offending part of your machine.

My X axis chatter improved dramatically when I upgraded to 9mm belts
