Thank you! A combination of meticulous leveling, brimming -- actually, skirting, just to be safe -- and a gantry adjustment has improved this a lot. This YouTube video was a savior: https://www.youtube.com/watch?v=36u4gberzC8

On curious thing I noticed was that, when a fully tightened (lowered) each corner as a starting point, as the video suggests, the back left corner was about 4 mm higher. I noticed there's a piece connected to the adjustment rotator on this corner below the bed connecting a cable, but it's only being held in place and limits the freedom of the adjustment.

<p>I have and Ender 3 Pro, which I'm enjoying except for an intractable problem. No matter how carefully I level the nozzle and tighten the X belt, using this <a href="https://all3dp.com/2/ender-3-bed-leveling-all-you-need-to-know/" rel="nofollow noreferrer">great guide</a>, the prints seem to be tilting to the right, particularly if they're tall. I realize this is a common problem, but I'm at a loss for what it's called and where the problem is most likely to be.</p>

<p>The first sign of trouble in paradise is that, after two layers of a simple rectangular base for a <a href="https://en.wikipedia.org/wiki/Bean_machine" rel="nofollow noreferrer">Galton Board</a> I'm trying to build that uses sand, the right side is clearly thinner than the left:</p>

The [level of the table top](/a/7892) has **nothing** to do with the levelling of the printer, nor with the leaning of your prints! You're just having adhesion problems, use a specific print adhesion spray or a hairspray or glue sticks.

Thanks! Would that explain the uneven level in the first photo?

I have and Ender 3 Pro, which I'm enjoying except for an intractable problem.

The uneven level is explained by the unfortunate choice of the printer manufacturer to **not have** a second Z lead screw. It is pretty difficult to level these printers, it is all a combination of the correct X belt tension and roller tension. The uneven level in the first picture is what is causing your print to detach, As can be seen you've got a lot of "squish" on the right side, but less adhesion (seen by the less transparent color) on the left, therefore it would fail on the left.

You need to:

* level better,
* fix the skew XZ gantry or
* use an [adhesive](/a/11183) (and/or a `brim`).
