Rotating ball nut, Ballscrew Pitch, RPM limits, and my particular build pickle

[JAZZCNC]

So here's the ball nut tuning / cleaning experience in video form in case it's helpfull to anyone:

The new screws arrived! The nuts are not the ones with the flange in the middle, as that would have required new angular contact bearings, and a whole new bearing block which was more work & expense than I was ready to stomach - maybe the next machine :)

Watching that I think you lost more than one ball, I saw at least 3 fly off when you tipped out of that cup...

Haha, yeah, thought I'd include that in the vid in case anyone (including myself) starts thinking I am in any way proficient at this stuff... Three escaped, but only one made it to the floor. the others got held up on the extended paper towel trap. I am reasonably certain they all found their way back in - there wasn't any space for more bbs in the nut anyway...

Ok question on the new ball screw though - Started a new thread about it:
