G0704 Ways Sticking
I'm in the process of converting a G0704 over to CNC and am having an issue with the X axis slide sticking. What is odd is that it is only sticking in the region between 1-1/2" to 3-1/2" on the ways and nowhere else. I would expect it to stick at one of the ends if it was a ball screw alignment problem, but there is no sticking out at the ends. If the gibb was to tight then I would expect the whole range to be hard to move. If I remove the gibb the sticking problem goes away, so it is not a bad section of ball screw. I really don't see how this could be anything other than a defect on the dovetail. Any ideas? It doesn't seem to be a common problem based on google searching it.
