Sorry I probably missed something, but Serial2 communication keeps restarting my ESP. I use Arduino CNC shield (on GRBL side) so I use logic level shifter, I tried several of them , I tried various power sources. I tried UART com between PC and shield, without conflict. Any thoughts? The Idea is brilliant, execution great so I love to make it work.
