For those of you who have converted your benchtops to linear rails instead of using the dovetails and gibs was it worth the trouble? Is there a certain axis you see more benefit for and would leave the other factory? I have a G0619 ive planned to convert for years now and am finally in a position to revisit the project. I have the mechanical parts but not the electronics. Before I dove in and started to deal with the gibb issues I wondered if I should bite the bullet and go with linear rails instead. If I did go the linear rail route what kind of preload seems to work well?

I do plan to add mass and stiffen the column in this process so hopefully that will make the mill a little more capable too.
