Few Questions Getting Setup

I think this is really cool add-on for printer and excited to get it going, but man is in desperate need of some complete documentation for how to setup and use it. Setting this up on RatRig VCore3 running klipper with direct drive extruder and have few questions.

-I think i need it to be in Mode 3 (hold button for 10 clicks then 3 clicks after that) based on one of the videos for my situtation. Correct?

-From what i have tried so far it seemed like even after i loaded the filament in mode 3 the chameleon motor didnt disengage and extruder could pull filament freely

-Where should the filament be when i start the print? 1" before the Y for each filament or should i load the first filament needed to start?

-In the Gcode for the initial location of the button be the coordinate for when button is engaged or next to it but not engaged?

Thanks!
