Neptune 3 serial ports #1

Hi,

thanks for sharing your mods. I like the direct extruder and the BananaPi-Octoprint.

I also added #define SERIAL_PORT_2 2 to my marlin config, but didn't get the serial connection working.

grafik

Red should be TX, orange -> RX and brown -> ground.

Which pins or ports did you use on the board?

Hey,

I'm sorry for the late reply! I have since switched over to running klipper instead of marlin. Nevertheless the pins you use seem to be the correct ones. Are you sure you set up the correct Baud rate in marlin and your BananaPi? Maybe try swapping the TX and RX pins? Other than that I don't have any ideas what could be going wrong.

I connected a usb serial adapter directly, to see if there is any output. Set the same baudrate in my console as for the serial output... nothing 🙁 I didnt switch tx and rx, as I tought my wirering is right, but yes I will give a try.
