Trouble with first layer for entire bed Ender-3 V3 KE

[user7683510971]

I am having trouble getting a good first layer for the entire bed.

I start by performing an Equipment Self Test. Here is the result:

I don’t know if those values are too big or if the auto leveling can adjust for it.

Next, I adjusted the Z-offset so that I was able to get an excellent 1 layer print of a square in the middle of the bed.

However, when I printed a 5 X 5 grid of squares as well as a large square, I got problems.

In the 5 X 5 grid, there was a small problem at the top, but the bigger issue is the bottom row.

Here is the large square:

Are the bottom offsets just too large? If so, how do I correct that? My old printer had wheels to turn to adjust the 4 corners, but I don’t see that on this printer.

Hi,

This video explains some method to fix the manual leveling : https://www.youtube.com/watch?v=ei4qkJiqV00
but it needs some extra parts it appears.

Those numbers look fine. If you want it perfect, you can adjust the plate mounting screw a tad to see if that helps. You can play around with the z offset to dial it in as well.
