Just curious: Would getting a bigger (more threads from top to bottom) nut to go up and down the Z-Axis make things better by averaging out any errors?
Perhaps more important: Would replacing the nut be almost as much work as replacing the whole Z-axis with an M3 or M5 rod?
Have you thought about using a ball screw.

Or, threadless?

Look for "M3 Z-axis mod" this is common. It has the added benefit of the M3 rod being thin enough to flex- any loads transferred to the support rod (loads should be confined to the support rods.)
I did mine with a ballscrew and it's pretty good. It's pretty simple if you have the aluminum bed. If you have the original wood bed it gets a bit more complicated but it's not bad.

Here is an example of the threadless Z actuator. Been using it for over six months without any problems. No banding or wobble. Works well with .1 layers if needed. There are many versions of it on Thingiverse.

Nah, I think I'm going with the 3mm rod. I don't want to use something that appears to be black magic on my printer :-).
Hahaha you said bigger nut.
Just presenting a different method to the Z axis issues. No black magic. It’s a proven way to move a carriage.
Hey KD,
What's on the underside of the z platform in your pic? Looks like another printed part.
A nut plate so I could tighten the screws from the top once all was aligned. Below that it the top of a the shaft coupling.
