Just to be clear, I'm using the connector circled in green in the image below:

Is this the correct connector?

@phaedrux
I've connected both cables and tried a couple of SD cards, unfortunately its just not reading the cards.

Do you think it could be a cabling issue? I've seen a few posts where this was the case

I'm using the PanelDue 7i.
Yes I updated the firmware myself. The file I used was called 'PanelDueFirmware-logo-3.4.0-7.0i.bin'.

I'm using the ribbon cable that came with the PanelDue, so 300mm long.

I tried the 4 pin wire, and it seems to be working now, this is great - thanks for the advice.
That said, I'm very keen to use the SD card slot on the PanelDue. Do you think it would be possible to use the ribbon cable?

Hi,

I have a Duet 3 Mini 5+ with a PanelDue. I'm running RepRapFirmware 3.4.0 on the Duet 3 Mini 5+ and PanelDue-3.4.0 on the PanelDue. I have them connected together using the 10-pin ribbon cable.

The PanelDue constantly shows "connecting" in the top right hand corner, it can receive information from the Duet such as warning codes and the IP address, but it doesn't appear to be able to send information to the Duet. For example, when the homing button in pressed nothing happens (the printer homes fine when controlled through Duet Web Control).

I'm using this command line in my config.g file:

M575 P1 S1 B57600 ; enable support for PanelDue

I have checked that the panel due is using a 57600 baud rate. And the soldering for the ribbon cable connectors looks good on both of the boards.

Does anyone know how this issue can be resolved?
