I just got the Ender-3 display working with Duet Maestro running firmware 2.02RC5. You have to activate the display as described by dc42 with gcode M918 P1 E4
(I used E4 because the response to the encoder was better).

Here ist the wiring:

The Ender display has 3 connectors EXP 1 to EXP 3. Some of th pins of EXP 1 and EXP 3 are named.

EXP 1 from the pcb side:

EXP 3 from the pcb side:

Some pins are have the same signals. EXP 2 has no named pins.

Maybe it's possible to use 2 standard 10pin cable to connect EXP 1-3 from the Display to Maestro EXP 1 and EXP 2. But until now I didn't have the time to measure and check if it's possible. I'll try to do the next days.

@droftarts
That was the fault in the config. Now it's running

I saw the mark in the wiring diagram but didn't thought about it

Thank you so much.

Board was used solo with the PanelDue and not connected to the printer parts.

config.g contains the parameter above. The PanelDue is configured to the same baud rate.
The settings must be right. When I change the rate the message with "established WiFi connection" is also gone. With 57600 baud I get the "established WiFi connection" message, so I think the baud rate ist right.

The funny thing ist, that everything works directly after flashing the PanelDue from the duet board.
It seems that the board sends a special command while flashing.....

Hello,

I have a problem with a Paneldue 7i in combination with Duet 3 mini5+ WiFi.

The display is receiving data from board on boot up. Showing established wifi connection etc.
but is showing "connecting" in the top right corner of the display and the buttons for homing etc. don't work.

I've tried different things to get it working.

One funny thing I discovered. When I'm flashing the display firmware update within the webinterface of the board. The board flashes the display with status OK and the display works perfectly. The buttons for homing etc. work perfectly.

But when I restart the board/printer the display doesn't work and shows the status "connecting" again.

Firmware on all parts (Board, DWC and Paneldue) is 3.4.0. Connected with 10-wire cable but using the 4-wire cable gives the same result.

Hi,

the easiest way is to use a bridge. Something like this (small, enough bandwith):

https://www.amazon.de/Vonets-300Mbps-Router-Wireless-Repeater/dp/B0148NO58W/ref=sr_1_3?ie=UTF8&qid=1544824135&sr=8-3&keywords=vonets+var11n-300

Costs about 20 euros and can be powered over the 5 Volt pins of the duet.

I'm using it with my maestro and it's perfect.

I also used those menu files and had to edit them. Menus are only for the base functions but a good base to extend with additional functions.

A mix between those files and the CraneQuadMenuFiles would be the best solution.

Maybe 2 cables (10 pin). EXP 1 LCD to EXP 1 Maestro and EXP 3 LCD to EXP 2 Maestro.

EXP 1 LCD to EXP 1 Maestro is almost perfect. We only have to check wether Beep and ENC_SW is on EXP 1 LCD.

The Ender display has 3 connectors EXP 1 to EXP 3. Some of th pins of EXP 1 and EXP 3 are named.

EXP 1 from the pcb side:

EXP 3 from the pcb side:

Some pins are have the same signals. EXP 2 has no named pins.

Maybe it's possible to use 2 standard 10pin cable to connect EXP 1-3 from the Display to Maestro EXP 1 and EXP 2. But until now I didn't have the time to measure and check if it's possible. I'll try to do the next days.
