Mk4s->Core one: First Self test Y axis failed
I read the posts about Y axis self test failed. Change the belt tension between 80 - 105 every ~5 Hz rerun the self test and it always failed. Y axis on the Edge position has -19 mm. I'm not able to fix it by any type of factory reset or doing multiple self testing. How I can normalize it so it will not have negative values?

Hi, check out this page:

I used this solution for my printer. Had to use some force to fix the problem.

That page is wrong. It says to NOT loosen the belts.
Not doing that will likely result in one of your belt tensioners breaking (don't ask how I know) or your belts pulling out of the Nextruder holder (also from experience).
Loosen the belts. Square the gantry. Tighten the two sides in tandem.
Trying to square the gantry while the belts tight will cause you grief. Reinstalling the belts is quite a chore.

Placing the full steps.
1. I failed to properly mount the belts like on: screen1. The tension was to big and I need to disassembly something.
2. I screw out the left and right mechanism so the belt is loose: screen2.
3. Then I was able to make it right and it solve my problem: screen3
4. I set both belts to 94-95 hz
