How much should I have. Is that good? It's spot on if I zero and don't change direction. On direction change I'm loosing .005".
Also, I haven't lapped the x-axis, but I'm getting about ~0.002" if I shove the table, and about ~0.002" if I tug on the table. For total table shift of ~0.004" When the table is centered within it's backlash range. I wanted to add, that I have snugged down the x-axis so that it can't move. That 0.004" play appears to be in the y-axis somewhere.
Is this good? I'm not sure how to adjust that out, if it's the backlash of the screw letting the table move back and forth. I have the gibs adjusted to where the table will move slowly with no real side to side play. I could tighten them more, but if the movement is in the screw, that wouldn't help much. Would it? I've snugged the anti-backlash nuts down, but I haven't really put any torque on them. Just good and snug.
