Yes... All that sounds reasonable! You may need to do a G29 A to activate it. But... I've fallen into this trap several times during development. Is your nozzle more than 10mm above the bed? If you move your nozzle to 1mm above the bed, you will see movement if the system is active. You can look at your topology map by doing a G29 O
Or, if you want more extreme proof the system is working, do a
You should see the nozzle rise as it hits the line and lower when it gets past it....
Incidentally... There is a Quick Start guide available now... Bob-the-Kuhn wrote it. If you search a little bit at www.github.com/MarlinFirmware/Marlin you should be able to find it.

- G29 P0 ; to zero the mesh
- G29 Q1 ; to put a diagnol line across the mesh
- G29 A ; to activate system
- G29 O ; to view the test pattern
- G1 Z2 ; to get the nozzle within the fade height
- G1 X0
- G1 Y 100
- G1 X 150
