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

[Bongo]

Hey JazzCNC. That sounds like very good advice. I plunged on and took the nut off!





I actually managed not to lose any ball bearings. Good call on the non-bouncy surface ;)
Didn't have a lot of time today but will make a small vid of the process - once I have successfully put it back together, that is!
Before Taking it off, I could feel with my hand that there was a little side to side play in the nut, though I couldn't detect any axial play that would obviously translate straight into backlash. Anyway, it made me suspect the balls are slightly undersized.

Agree, I probably am better off selling them and going to a higher pitch. What is your experience with cheap Chinese ones vs the branded,JazzCNC? 32mm pitch seems a lot, but I see that it does seem popular to match pitch to dia...

As a side note, the ball diverters are actually metal.
Thanks again for all your thoughts, keep em coming.
