A few of the holes had some stringing which make the nut insertion a little bit more difficult, unfortunately I didn’t keep track of which ones. It wasn’t that big a deal.
Is your print from the current v7.0.0-beta3 release?
Yes
And the x-axis securing hole is one of the motor screws?
Yes, it was the right hand motor screw when viewed from the back. The hole gave a bit as I tightened the screw and so I can no longer make it very tight, but it’s not affecting functionality.
