So fedex finally arrived this morning with a parcel from Chai,

Packaging was a bit limited compared with the other parts I have recieved from China. Upon inspection it looks like at least two of the longer ballscrews have quite a bit of a bend to them. I dont have a dti to hand but turning them I can see it by eye.

Is this a common thing? and how does one go about straightening them ?

I knew it was all going too well :)
