I just got everything bolted back together and I went to put the carriage on and I noticed it wouldn't sit flush against the ways and that it was being held up. I took it off and measured with my caliper and the ball nut mount is around .050" too big to fit in the pocket.
I believe that this is what initially caused my binding issues when it was close to the top of the travel and that it bent my screw when I was running it up and down. This is unfortunate because I might be out a screw and a lot of time if it is bent too badly on the motor side.
I am attaching a picture for reference but I am going to email Billy and see if he recommends machining the mount down a little bit and then trying it again to see if it works.
What do you guys think?
I had almost the same exact problem you did. The Z ball nut mount didn't fit in that recess..made it fit.. Put the two screws in and the ball screw was having binding issues. Then a little screw wobble, so I had to fix my bent screw with an arbor press. Realized my ball nut mount needs to be a little taller so it doesn't pull up on the ball screw when I tighten those two mounting screws.
