The build manual and the display panel gives up some tools to level the bed using three bolts.
But, my eyes were having a hard time seeing the hot end height. So, I decided to make some tools to help me do this more precisely. First, I bought a set of mechanic's valve tappet gauges. Using a gauge under the tool that I am going to describe is the most precise way to ensure that all points are even.
First the tools...

|Tools hung over at each end of the X-Carrier rails.|
Do this front and back.

Finally, I had created an earlier set of alignment tools designed to do the same thing. However, these sat on the bed, itself and had clips similar to those of the X/Y Carrier alignment tools. I now use these just to verify that the bed is level.

The latter step is not really required. I simply have the posts already and it's a good tactile way to verify that the bed is level. Raise or lower the bed until one of the tools clips easily on the carrier rod and the other tool should also clip easily.
Once bed leveling is complete, we need to adjust the hot end height. And, for that I also use the mechanic's tappet gauge.
