My G704 is one of the early versions. In fact, it is #85 in 2010. I converted it to CNC immediately and have been running it A LOT since then making some parts I sell. In a recent lull in activity, I decided to reduce some of the backlash, finish the enclosure, and build some motor covers for flood coolant.

Put slightly larger balls in the Y axis and all worked very well. Somewhere in the .002 range of backlash. Same treatment to the X axis, BUT...

I can't get the blankety blankety gib strip to go back into place without locking down the X axis. While it was out I spent a little time improving the flatness of the strip by sanding it by hand on a piece of glass. Very little material was removed. It should not have changed the angle of the material. Everything is lube up well. I have loosed up both ends and the ball mount in an effort to insure everything is lined up. The gib strip will go in until about 2 inches is sticking out and it will begin to lock up the access.

I am at a loss. Any ideas?

A few ideas.
You sure it's not upside down? Check for any burrs or dings in the dovetail edges.
Are the lock handles still installed? The brass pins they push into the gib strip can pinch in the hole preventing the strip going all the way in.

I have tried it upsided down, right side up, backwards and from the wrong side. Locks were removed when originally converted. The only thing I have not done is tear it back down, which I will do today. Has to be something in the way.
