First layer calibration, issues.

Printed the single layer calibrations file.  In the attached photo, I haven't modified the z-levels at during the print.   It's almost as if the left side of the print bed is systematically lower than the right.  I've run the mesh bed leveling calibration several times.   Has anyone seen the same?

RE: First layer calibration, issues.

I assembled my mini+ yesterday and haven’t been able yet to make a descent print. I have taken some measurements and the Y ax is several degrees off. Also I noticed the x ax is not level. There’s a gap from 2-3mm between left and right...

this is the sixties attempt for calibration, but up untill now it did not work properly...

You might be too low.

That is too high.

Getting Live-Z right is definitely a goldilocks exercise. I've put together some notes and pics showing the Live-Z process here that you might find useful.
