1st project guidance: mini chop saw automation (with CNC shield)

To keep track of the global project progress, in this topic: Wiring of limit sensor & inductive proximity sensor on CNC shield we figured out so far:

  1. Arduino pins <-> CNC shield v3 pins mapping

  1. optical endstops wiring (it is not like I supposed into previous post)

  1. We have a first proximity sensors wiring principle, but unfortunately it requires additional components
