Clone paneldue won't connect

[JonasBaleine]

Hi,

I use Duet Web Control 3.4.5 and RepRapFirmware for Duet 3 Mini 5+ 3.4.5.
I have a clone paneldue 7i running firmware 3.4.1, but it won't connect to my printer.
I added the line M575 P1 S1 B57600 to my config.g file.
When I turn on the printer, I can see the messages coming from the duet board, as shown in the picture below, which would tell me that my connections are correct.
The board communicates with the paneldue, but I assume the paneldue does not communicate with the board.
I tried different cables, I checked continuity as well.
I tried the firmware 3.5.0 for the paneldue, but did not connect either.

I tried the paneldue on my duet maestro printer as well and I have the same behavior.
So I suspect there is a problem with the paneldue, unless there is something else I could try?

Thanks!

@JonasBaleine i suspect the issue here is that the cloned "7i's" aren't actually 7i, but rather a V3 7" with the controlled integrated.

Try flashing it with v3 7" frimware and see if that helps!

@Exerqtor I bought the clone paneldue in 2019. Never got it working then, but had not tried that hard either. I did flash the v3 7in firmware this morning by mistake and the colors were all messed up on the display.
