Ill pull it out today and have a quick look on my welding bench. Its about as flat as I can get until I get it to work on Monday to check it on the granite surface table. I'm a bit disappointed that this is a problem, I really shouldn't have to try and straighten a precision ground ball screw.

It's not a precision ground ball screw.. it's a C7 ROLLED ball screw.. HUGE difference.

I agree there is a large difference, but regardless, its still a huge pain in the ass and in my opinion shouldn't have been an issue in the first place.

I checked the ball screw and it was in fact bent. I used a small arbor press I had in the shop and managed to get it straight-ish. Its definitely better than what it was, but not perfect.



I also took apart the ball nut again, checked and re-packed it and made sure when I was assembling it, that a ball didn't get stuck between the circuits. Its still a bit noisy by my standards, but I'm going to leave it and try it as it is.
