    Thanks Bonestock. We are currently waiting for some downtime to begin correcting the issues. I will be sure to look at gibs and the ball screw and components. I see how having a ball bar on hand...

    Thanks Daryl, that is all very helpful. The one machine is Heidenhein 425, the other 530. I'm not sure if the servos in the TNC 425 can be tuned, but the 530 can. Thanks for all the...
