How to square gantry in A10,A20,etc

[Liizok8u]

Hey,

i allways wondered why even with perfect bed leveling, my prints didn't turn out great. With my square I noticed, that the hole gantry is tilted a quiet noticeably to the back. I tried to unscrew it (on the bottom) and straighten it. But when I tighten the screws, the gantry tilts backwards again.

I allready removed the spool and placed it in a holder next to the printer. I did not see any benefit in putting high weights on the top of the gantry.

Any tips on squaring it?

Hi,You can check if your x-axis guide is normal,
Whether the upper and lower bearing wheels of the hot end are fastened.
