Panel Due stopped working

brian · 5 Jun 2018, 12:43

My 7" panel due stopped working while is was using it. Black screen. Wires are connected ok. Is there anyway to check to see what needs replacing, tft screen or the controller? I have been unable to connect to the duet wifi via usb or web interface for some time so cant check anything that way.

The most common reason for this fault is a failed backlight inverter on the TFT panel. If you have a multimeter, you can check whether it is producing any output.

Check also that you haven't erased the PanelDue firmware.

I checked for voltage on the duet board and there was 0.8 volts. So purchased a new tft and that didnt solve the problem, so purchased a new panel due and that works except the graphics are upside down or reversed. What do i need to do to set that right.

As a side note the old panel due/tft was constantly blinking no matter what i did would start blinking. This new one is not doing that and looks very stable, just not the right way around.

Thanks in advance so your support.

There is a button in the settings page to invert the display. That should get it right way round for you.

thx Phaedrux, that worked, had to use a mirror to read it but it worked!

Your new PanelDue controller probably came programmed for the 5" display. If you run the 5" firmware on the 7" display, the colours are wrong and I think the display is the wrong way round too (as you found out). So if you want to get the colours right, you will need to upload the 7" firmware to it.

Yes you are right, it is the wrong color. can i assume some of the functions also wont work, eg i cant set z to 0 using G92 Z=0?

Also looking for instructions to update the firmware (for panel due) but cant find so far.

@brian Instructions are here: https://miscsolutions.wordpress.com/paneldue/

Yes thanks, i finally found them and successfully uploaded the firmware but...

now when the tft displays the menu (after several tedious seconds of the logo displaying) there are no boxes under the hotend icon so i cannot set the temp. Also trying to print via the sd card produces no results.

when the tft first lights, i can see the boxes under the hotend for a split second then it disappears. there are boxes under the hotbed icon.

Phaedrux · 17 Jun 2018, 02:01

@brian are you sure you have the right firmware for your controller?

brian · 17 Jun 2018, 02:34

Ok, i down loaded the nologo version and it works,

brian · 17 Jun 2018, 02:37

wait, once plugged into duet, it no longer shows the the boxes

brian · 17 Jun 2018, 02:40

yes i have the 3.0a controller and downloaded the v3-7.0-nologo.bin

Hi.
My Panel Due stopped working after an update.

Updated using bossa (writing and verifying were successful) and now the screen is black.
I have to connect it multiple times to get it recognised, and i still can write and verify, but no matter which firmware i try, it doesnt work.

I think either you don't have any tools defined in config.g, or the Duet firmware version you are running is too old for the PanelDue firmware you have installed.

Are you quite certain that you have chosen the correct firmware? Which version PanelDue do you have, and what TFT panel?

brian · 17 Jun 2018, 16:21

@dc42 The panel due is v3.0a and the 7" tft i just purchase a few days before the new panel due and i downloaded the v3-7.0-nologo.bin. Checking the tft setup shows at the top of the screen "Panel Due firmware version 1.21.3(13b1)"

The duet wifi is v1.0 and firmware is 1.19 beta 7.

As for the config.g, it is the same as before and has worked for many months.

; Tools
M563 P0 D0 H1 ; Define tool 0
G10 P0 X0 Y0 Z0 ; Set tool 0 axis offsets
G10 P0 R0 S0 ; Set initial tool 0 active and standby temperatures to 0C

Phaedrux · 17 Jun 2018, 17:43

@brian is there a reason to stick on 1.19 beta 7? Might be a good time to do a backup and try upgrading to 2.0

brian · 17 Jun 2018, 18:06

@phaedrux no reason, in fact i thought i had upgraded. i'll try again.
