Serial communication
-
I know that you can communicate using the panel due port. I currently have a lcd connected. Is there another serial pin? Im using duet ethernet.
-
Afaik only two uarts and one is used with the usb port, the other with the PanelDue. If you want to use the usb one you need to either look into re-mapping the pins(not sure if possible) or connect it to a usb host and go from there.
-
I don't use the usb at all. Only ethernet for communication.

There is one other possible solution not mentioned in that thread. If you don't use the SPI daughter board connector for anything, and don't use a ribbon cable to connect the PanelDue, then you could program the USART that handles that SPI channel in UART mode.

I was facing the same problem and solved it by utilizing a ESP32 in between the Duet3D and the PanelDue, a serial port splitter, so to say.
If that's what you're looking for, head over to Github. There you'll find a description of the project and the firmware source code.
Using a ESP32 seems a bit overdrawn but eventually, you can do so much more (i.e. controlling it via Bluetooth or WiFi - or make use of the additional port pins to address servos or relais) in case you need it. -
@technik-gegg That's a very interesting solution!
