So the issue is pretty much exactly as the title says. I only noticed this as I was having issues cutting steel (MAJOR chatter even in light cuts) and I took apart the table to try and see if something is loose. Putting it back together and attempting to readjust the gib is where I noticed this.
With the gib installed at it's loosest setting, the center of the table obviously has a fair amount of play and each end tightens up a good bit. Keep in mind I'm getting a feel for this with the ballscrew disconnected and sliding the table back and forth by hand. As I was re-assembling it I wanted to tighten the gib to remove as much play as possible while keeping movement smooth.
If I had to guess, this may be the cause for my chatter issues (or likely a similar issue on the Z axis ways).
Does this seem like an issue with the gib or the ways themselves?
