MK3S+ X-axis stutter half-way during calibration

I just assembled a MK3S+ which has been working fine, but noticed that the X-axis belt tension had a reading of 235 and so wanted to adjust it down.

I was successful in getting the belt down to a tension of 255 and having it pass calibration - but I do notice that, during the belt calibration process, there's a minor 'stutter' that happens when the head moves from left to right (not right to left!), more or less exactly at the mid-point of the bed. Adjustment seems to indicate that this is worse the looser the belt gets, too.

Is there anything I can do to resolve this? It might have happened all along, too, and I just haven't noticed. Thanks!

Does the X carriage move smoothly from side to side by hand? if not, Have you tried Greasing the Smooth rods?

Video attached - although, of course, as soon as I started recording, the problem improved 😉 That said, I'd also greased the rods a little at that point.

It moves fine side-by-side manually, and is now barely noticeable - see the recording. I also notice a minor Y-axis glitch, too - perhaps it's nothing to worry about?
