Z offset wizard and firmware updates

Just a word of advice. You may need to re-run this wizard after some firmware updates.
Heck, just run it again after all of them.
They have been "tweaking" how the Z offset is calculated apparently. How do I make that call?

Well, with no mechanical changes the Z offset has varied (with firmware changes) from -5.x initially to -11.x now...

So, just be aware that they are apparently using a moving target here

 

And for fine-tuning the bed leveling small strips of blue painters tape up inside where the ball magnets connect is an easy way to micro-tune it.

 

Obviously not software people.

 

They broke the "rule of least astonishment" that is for sure....
