Summary

Added auto bed leveling to my Cloner. Works great. I am only using one extruder so i used the unused side of the extruder mount to connect a Z probe. I printed at 20% infill ABS. Modifying the factory Marlin to add bed leveling was not going to be easy so i simply used a newer version of Marlin and modified the mechanical settings to match.
The factory build plate is aluminum, so if you print directly on that there is nothing else to be modified.

I designed this with some Cad Cam software i use for work so i do not have an openscad model. Sorry.
