Make a new video so we can see and hear whats happening now you've tweaked it some more!

I was about to say the same as Voicecoil re making sure everything is clean, I always suggest people do that with the nut's because I don't think I've seen one yet that didn't have crap inside from the factory.

It can be tricky and the balls will fall out if you remove the nut from the screw, that's OK because your going to flush it all out and clean everything anyway but it can be a little time consuming reloading all the balls back in, to do this pack the nut with some grease first, enough to hold them in place not literally "packed".

The trick is getting the nut back on the screw without dislodging any of the balls, its very doable but equally easy to try and go to fast and knock the balls back out when your trying to thread the nut back on.

While/if your there, count how many balls you've got out altogether, its common for some to be missing from the 17 per track on a 1605 ball nut (even from BST).

Have another read of this thread re nipples and so on, you can include the ball nut: http://www.mycncuk.com/threads/12835

Also (for everyone), if you read the document from Hiwin on the their Linear Guideways it has quite allot of info, Page 27 (2-1-7 Lubrication), shows you info on the grease nipple and ALSO the additional mounting locations built into the blocks so you can move the nipple if you want to: https://www.hiwin.com/pdf/linear_guideways.pdf
