Front Z steppers, 1-2mm of missaling, impossible to recover
Yesterday arrived my factory assembled core one.
And I noticed the bed it's tilted, even if force the Z steppers to ram against the base in calibration menu I can't get rid of these misalign.
RE: Front Z steppers, 1-2mm of missaling, impossible to recover
Did you try moving the print bed to the bottom, disabling the motors (or turning the power off), and turning each z-axis lead screw so the print bed blocks touch the z-axis mounts on the bottom?
Those three z-axis mounts are the reference points for the print bed. Then when you power back up, the stepper motors will keep the print bed aligned with that reference plane while they’re active. If you move the print bed while the stepper motors aren’t holding position, the reference is lost and the bed won’t be square to the x and y axes.

Yes. Tried these.
Finally I put a 1mm spacer on right Z stepper, run the Z align again and now I got my bed squared to the gantry.

Ruler squared with bed/side panel, now I have the same distance to the gantry, before that I had 1mm of diference.

Try lubricating the lead screws then re-home the z. This has fixed the issues for others.

If the gantry is not parallel to the floor of the building chamber where the z-axis motors are mounted, you could try loosening the gantry frame and the four vertical corner pieces, readjusting them, and tightening it back up. I’m surprised that it would be off be that much, though. Anyway, you can see how those pieces go together in the Core One kit assembly instructions.

RE:
i got the same problem, but my left side is hanging down, may you be so kind sharing pictures of your solution, please? 🙂

The better way to measure this would be to measure the distance the nozzle is from the bed and move it around the 4 corners measuring at each corner.
You could attach a dial indicator to the print head. After taking your measurements you could then print some permanent spacers to attach to the z motors. Then even if you rerun the z axis homing it'll still be correct.
