Been trying to find a fix for this for a while but I haven't found anything that helps, wondering if anyone has any advice. I'm an artist not an engineer so all of this is new grounds to me.

I have banding on my prints that match up to the threads on the rods, in both height and depth. I've tried adding some anti-wobble mods, they made no difference at all. What am I doing wrong?

How easy does your carriage move up/down (z direction)? Maybe it gets stuck a bit?

One image in the building instructions is wrong -- it shows that the rings on the x carriage rods should be on the "outside", but in fact they should be in the "inside", as to prevent the belt pulling the two sides together (and making it stuck).
