Paneldue woes

Helensdad · 30 May 2019, 12:28

I connected my new Paneldue 7i to the Duet 2 wifi board with the 4 lead cable, plugged duet 2 into the USB port on my PC and all I get is a blank, backlit screen. If I connect Paneldue directly to USB all appears to be working. I updated the firmware with Bossa to PanelDue-5.0i-7.0i.bin, uploaded and verified cuccessfully but it still won't work when connected to the Duet board, again, just a blank backlit screen. I have the integrated version without the separate control board. Does the Duet need to be connected to a PSU as well as USB to work properly? I have also read about a jumper on the Paneldue controller needs setting to 3.3 volts but I can find no such jumper, so what am I doing wrong?

There is no jumper to be set on the 7i. You should not need to provide USB power to the PanelDue when it is connected to a Duet that is powered from VIN power and has the on-board 5V regulator enabled.

Are you powering the Duet from VIN power, with the INT_5V_EN jumper in place on it? If you are powering the Duet from USB power only then your USB power source may not provide sufficient current to power the PanelDue.
Which cable are you using to connect the Duet and PanelDue? If it is the ribbon cable, make sure it is plugged into the correct socket on the Duet - the one marked CONN_SD. If it is the 4-way cable, check that the connections in the cable are correct - the wire colours should be in the opposite order from one end of the cable to the other.

Many thanks, connect 24V psu as that is what I will be using to power my CNC router...

From my experience, connecting the duet to a computer via USB, without 12V or 24V vin, does not provide sufficient power to reliably power the duet and the panel due connected to it. Connecting a proper vin solved the problem for me.

I had semi-similar issues also setting up the 7i with Duet WiFi. The 1m servo cable that I received would allow the panel to power up but would not communicate with the board. Some research found that less than 1ohm resistance through wiring was needed. I needed to use a little larger conductor wiring. Also as DC suggested, make sure connectors are pinned correctly.

All up and running nicely, Connecting to 24V psu did the trick. Many thanks...
