3D Print bed auto leveling - help

I am purchasing a auto leveler for my build as trying to keep the bed perfectly level has become a challenge.

Dear fellow builders:
What additional code or adjustments do I need to add to the RAMPS functions in order to auto level and do I need different software than just Repetier-Host?


Auto leveler?

The bed compensation code as far as I remember is only going to work for 3D printing. And only on a planar lever it won’t adjust for a hump in the middle of your bed.

You can always will your surface flat 1 time and be done with it our use a sheet of glass and shim the corners.
