126+ Ender 3 4.2.7 Bltouch Wiring
126+ Ender 3 4.2.7 Bltouch Wiring . Most of the steps are applicable to v4.2.7 board, except the firmware version. Ac bed wiring with a ssr for control; I can confirm that the 5 pin wiring harness that came with the bltouch 3.1 will work fine in the dedicated bltouch port on the new board, and will not fry the board.
