Basic Wiring Confusion...

  • ...hello Friends.

    I'm installing a v4.2.2 board to my E3, and i don't understand the "TB" and "TH" connections on the board. I have a 2-wire white cable coming from the hotend, and also a 2-wire cable coming from the cluster. This all comes with my next move to be installing a 3D Touch. I shouldn't be doing this, no one should have let me near a 3D printer, but here we are. :0

    Thank You.
