Today I installed the motors that Prusa sent me to replace the original ones, whose lead screws had mismatched pitches.
I tested the printer and now the bed stays perfectly level throughout the entire Z travel. Before, the bed tilt kept increasing as it moved up along the Z axis.

Thanks to Prusa for their great service! 👍

Good to hear you got it resolved mate.
I ended up with 3 x motors matched and in tolerance (now inn the printer) + 3 motors out of tolerance.

I just need to find a project to use the out of tolerance motors on now 😂
