RE: New kit MK3S+ first layer problem
are you using 7x7 mesh bed levelling?
I find the Prusa first layer calibration, hard to use, so I use this process
these values are unique to my printer, your values will be different, look at both top and bottom...

RE: New kit MK3S+ first layer problem
I have changed to 7x7 and i print the square but result is strange even if life-z will be wrong
Can someone point me what can be wrong?
I mark also left "margin" with red questionmarks.
There is also some vertical artifacts too.
RE: New kit MK3S+ first layer problem
The problem was not calibration of Life Z but srew in X and Y motors xD.
Like in this post.
RE: New kit MK3S+ first layer problem
In your very first image the first layer looks good, but the lifting edges are a sign of a dirty bed. You can even see particles on the bed above the rectangle. Clean that sheet well.
