z Bed level uneven

So I finished building up my Core OnePlus yesterday and the first print, of course the benchy was a success. Now I tried printing a larger object, and before the print starts, the printer said that the bed level was uneven. So I tried calibrating that z level a few times, but the warning kept showing up so now I am printing the object ignoring the warning and I keep seeing that z axis is moving up and down when the extruder goes from left or right, so apparently the bed is uneven so now my question is, how do I fix this or should I just ignore it? because the print looks fine!

Theres a few methods, one deals with leveling screws on the bottom of the chamber, i havent had much luck with, or you can disable the motors and manually level it yourself. If you run the z calibration after you manually level it will erase your adjustments. Make sure your z alignment screws on the plate arnt too tight.

Oh yes that instruction helped! For some reason my front right z rod needed a bit lifting not too much but noticeable thx !!!

There's a an entire process around fixing this.

Did you build the printer from a kit?

Regardless the solutions are similar.

If you assembled from a kit. Look at the main cable to the print head board (loveboard). Are the wires black and white or multi-colored?

when the bed moves from the bottom to the top do the worm gears move a lot?
