RE: Bed Leveling Failed on CoreONE upgrade

I'll suggest one more thing: sometimes it's worth switching to manual Z-axis movement and going all the way down to Z=275. If the motors whine, it means the bed has mechanically leveled. Maybe this will help someone.

Or just run Z Alignment Calibration from the UI.

When I encountered the error I originally thought the problem was that the printer thought wrong. Turns out I under tightened the back screws of the heatbed with the lock nuts.

When I encountered this post I originally thought that it gave rather strange advice. Turns out it was just link spam in the making, right?
