Bed levelinator

I mounted a dial gauge to a 2020 gantry plate using a bit of aluminum bar with a 90 degree bend and a couple of holes drilled in it.

Now I can replace the x carriage with this when I need to level, and it will give me a continuous reading as I move it around. I even made it a little parking spot out of 2040 scrap, mounted to the top of the frame with an L bracket

The best way I've found to use it is to position it vertically over bed leveling screws and adjust those directly in two or three passes.

You can get gantry plates for ~$5 and a dial gauge for ~$10.
