I get some pretty nasty noises when printing in the X direction. You can hear them on this video: goo.gl/photos/FAxVUHsZuwXrZ8PQ9. It actually sounds worse in real life. Any ideas what the problem could be? Belts too tight, perhaps, or some problem with the motor voltages. I am using RAMPS 1.4 until the X5 comes back into stock, with 1/16 microstepping.

Yeah this is a fairly common problem, but the 1/16th stepping will definitely amplify it. Your best option to fix it is to reset the tension between the two x axis rods, you will want to add some more "pre-tension" between them to minimize the vibrating noises. You can also try loosening belt tension if that doesn't help!

I remember that part of the instructions (step 16). It's quite hard to apply what it says as it relies on a subjective judgement which seems hard to put into words. I wonder if there is anything you could do to improve this - for example, how much is a little bit of resistance, how much is too much, should I feel the resistance all the way along the travel or just at the ends.
I have adjusted this and it is slightly better, but still not great. I took the belts off as otherwise you can't tell how much resistance there is, and it would be nice to not have to do that if it takes a few iterations to get it right. The way I have it now there is not much resistance at the middle of the travel, but some at the ends.

I wanted to add a footnote to this. I recently reprinted the X axis parts using this modified version (http://www.thingiverse.com/thing:1428191), in PETG. I think this may have given me slightly better alignment, as it is now super quiet. The loudest noise when printing is the fans. I checked the alignment by measuring the distance between the rods for the X axis, and also using a digital spirit level to check that they were the same relative height all the way along. I didn't do the same checks with the original blocks, so I can't say if there were any problems there.
I still have more things to tinker with, in particular my retraction settings aren't right yet, but I'm not getting some very precise prints.
