I can confirm that the firmware 184.108.40.206 and BL touch 3.1 do play nice together.
Hi, I have BLtouch version 3.1. The cable between the BLTouch and the PCB has only 1 JST connector for the BLTouch. The other end of the cable just has female headers to connect to the adapter boards.
Do you know which JST connector is needed to connect to the PCB mounted to the frame?
