Serial connection to SKR Mini E3 v2
March 13, 2022 12:03PM
Hi all

I have an Ender 3 with an SKR Mini E3 v2 and while testing this new pi clone, it seems I have managed to fry the USB port. I'm using an old 12864 console, so it seems there's a serial port in the TFT plug that should be usable with octoprint on a pi. Any idea how to configure this serial port with marlin?

thanks

roy

You look at the pin diagram where is it clearly documented as to what serial port this is

[github.com]

You then set SERIAL_PORT (or SERIAL_PORT_2 or SERIAL_PORT_3) to that serial port number.
