Bed Leveling
I've been curious about the bed leveling on my new Core One. It prints fine, but I wanted to know how flat the system thinks my bed is, so I downloaded OctoPrint and installed the bed level visualizer plugin. According to that software, I've got a nearly 1.5mm drop between the back and the front of the bed. That surprises me because I know there's a separate stepper in the back vs the front. Why doesn't that stepper drive the back up 1.5mm to level the bed, and then use the bed leveling to do the intra-bed flatness calibration. Is there a calibration I was supposed to have done when building my printer?

There is the Z-axis calibration but some have found it necessary to install shims to start with a level bed. There is one of these projects on Printables. I’ve run the same on mine but I haven’t bothered with it since I haven’t had any bad prints to date.

I've done that too, it's a good tool to tune the bed leveling. As @hyiger mentions, there is a bedlevel correction mod to address the issue you found. In my case, I used an 0.4mm correction on the front left and the neutral one on the front right. I think the need arises from the modular construction of the printer housing.
Beware of that visualizer, a body can get way absorbed in fine tuning. Ask me how I know...
