Purchased MK3 2/5/2024. Met Bill at RMRRF 2024, he mentioned switch isn't required for people running Klipper. Is that true for MK3 firmware, or do people need to update to MK4?

"2) Attach switch mount to printer - this needs to be in a location that gcode can press it" Am just getting started, trying to find a quick start guide that gets me up and running in 1 hour, lol :-)
EDIT: Am rewatching the "START HERE: 3D Chameleon Mk2 and Mk3 Basic Installation" and Chris's video series before asking additional questions. Cheers!
Honestly, am struggling to grasp fastest path to a successful print. Will be capturing/corralling/sharing notes (for my setup...) at https://forum.v1e.com/t/mp3dp-v4-mod-azas-3d-chameleon-mk3-mk4-mmu/43578 hope that helps make up for the questions I'll be asking...
Saw the neat Direct connection and control of “3DC Selector” and “3DC Extruder” Steppers from Printer controller board post. But that requires spare Stepper slots (e.g. BTT Octopus). I appreciate the author sharing info and config that's working for them. But, that approach seems more complex and time consuming that just tapping into the "3DC Switch" from a Printer Controller board endstop GPIO.
Will try out Bill's wiring suggestion (use endstop GPIO + common ground) of "... M42 or Klipper's pin command to set the state of the pin... use G4"
Am wading through the various Klipper forum topics and referenced repos. e.g.
https://github.com/3dcoded/3dchameleon-klipper
https://github.com/alexpthe1/my3DChameleon
Rather than fumble around in the dark, would greatly appreciate pointer/suggestions of the latest greatest to follow? Cheers!
