Mesh bed leveling
I'm working on auto mesh leveling and want to make sure its working as expected. The prints are coming out nicely, but the picture looks a little weird. It looks like the firmware things I have a bigger bed?

How big is your bed?
How big is the mesh grid you've specified?

Also, the visual is kind of deceiving, the color gradient shows a tiny difference between parts of your bed surface. Some people get scared when they see a small bump when it usually isn't much to worry about. But with what Phaedrux said, you could change the defined mesh grid to probe more of the bed.
I'll have to check my actual settings when i get home, but when the probe goes, it seems to cover most all of the bed, its a 235x235
It looks like it's missing the row with the lowest X coordinate. the likely cause is that you have a Z probe with an X offset for the nozzle, so the probe can't reach that X coordinate. in which case, change your M557 command to start at a higher X coordinate and use a lower X spacing.
Interesting, I will try that. After you mentioned that I noticed these :
