Bended ballscrews. What i can do?

Wal thanks for your answer.
Dean of course I believe you
The main reason I upload the videos and the photos is because I want to get a general idea from other members that had the same problem, and get some advices about what to do with Chai.

1. Ask him to replace the ballscrews
2. Ask for a refund.
3. Do nothing because this bend isn’t enough.

Is this bend enough to make such a claim?

Also should I try to straighten the ballscrews?
It is more than possible that if I bolt everything down the problem will be reduced but my main concern is the forces that will be applied to the ballnut and the carriages are enough to ware linear rails and ballscrews.

Generally I want your opinion-advice about what to do with Chai

Routercnc mine ballscrews have a runout 2mm one 1603mm long, and 1mm the other three. You can see that at videos 5,6,7 when i turn the nut with my hand and not with the cordless drill.



Thanks for your time.
