This is just an FYI as I have a workaround and I prefer the homing behavior of the Genesis v1.4 Firmware anyway.
I have a Genesis Farmduino v1.5 and I’m running FBOS 9.2.2
I have found that if I configure the Firmware to Genesis v1.5 then the RPi seems to have an issue connecting to the Arduino, however I think this may be misleading as everything still “seems” to work.
When I configure the Firmware to Genesis v1.4 the connection problem goes away.
