When my Ender 3 S1 (not plus) had bed leveling issues, the problem was caused by backlash on the Z axis. It’s important that the Z axis be just loose enough that downward motion is driven by gravity. If instead the Z screws have to “pull down” on the gantry, then the height will be too sloppy for ABL to make fine adjustments.
You are too close everywhere. Im not using abl, but dont expect perfection from it. I believe if you increase offset it will be good everywhere. Machine can deal with small error, but not if its too much
I’m agree! But look at my picture, how can it be good at some point, and to close at others?
