There is a new display in the i3 Mega S built in. Seems it is the same display like the one which is used in the Anycubic Mega X.
The special menu is not shown anymore.

Does everything else work as expected or is just the special menu missing? Did you insert an SD Card?

That's technically impossible. Maybe your firmware update did not succeed? Either the display and the file listing works correctly or not at all, because everything is based on the same code.

Can you verify that you've got the Trigorilla Motherboard with Atmega2560 and not the 32bit "Trigorilla Pro"?

"Oliver Köster notifications@github.com schrieb am..." -> are you german? ;)

Can you tell me which firmware is shown in the display, when you click on Tools -> More -> Info?

(In english - maybe someone else is interested in this topic too)

Could you please install the original firmware and show me a photo of the info-screen on the TFT? I'll investigate the issue. "V116" is the custom firmware label, which is provided by marlin but it is commonly ignored by the display, so I didn't change the value. Normally something like "1.1.2" or "1.4.0rc" is shown.

Photos of the tft info screen before and after the update and also a photo of the non-working special menu would be great. I'll dig into it. Since the Anycubic Mega P (Pro) arrived, there is also a new display firmware out there... sadly anycubic didn't want me to have the firmware :(

Right here, I cannot see any attachments if you reply to an email. You need to log into github and upload the photos there. ;)

Damn! looks like you got the display from the new "Mega P" which also looks like the "Mega X".
That's weird... I'd really like to see the insides of the printer ;)

Seems that I now need another printer with this particular display to edit the firmware. My hope is, that the file list inside the display uses a sanitiser to get rid of special characters (like the ".." or the "<" of the special menu). Maybe I can work around the issue...

Please let me know how i can support you.

Right now i flashed your modified firmware. I would say partly succesfull. Please take a look at the attached photos.
The special menu is showing up now but unfortunately it is not accessable.

Oh and I forgot: You need to click on "refresh" instead of print, to accept entries in the special menu. But at this point, you might be stuck inside, because the menu handling is still the old one.

Could you please try this firmware?
If I am correct, you should see and now use the special menu... and maybe I can create a version, where both displays are supported. Also my goal is to use the "Print" key as "enter".

get_into_special_menu.zip

If it doesn't work, I'll create a testing-firmware, which creates a list of items in the file menu with different (hopefully supported) characters.

As long as I don't have this kind of display, I need you to test everything. "Blind" programming is a bit of PITA ;)

I flashed it right now. The situation is same. No reaction if trying to accept the special menue.

Next one... now with debugging output and hopefully working directory-listing. The missing directories are our problem atm to get the correct index.

Can you make a photo of the file listing when the original sd card is inserted?

Attached the file view of the SD Card with the Windows Explorer and what you can see on the TFT:

The double entry at the top is weird...
But try this. Maybe you can see folders now.
I really need this touch display to test it properly :/

Hmm.. okay. Does this make any difference?
EDIT: Deleted.. doesn't work.

There must be some timing issue. If the output differs from 05 to 06, the display also needs other serial timings :/

Thanks :D
Not all menu items are working at the moment and I need to rework the file handling. Also the menu is ugly AF but I find a solution for that. I promise ;)

Also the folder navigation is a bit tricky, but I do my best.

You are printing via USB don't you?
The firmware is a prototype only for testing the TFT.

I reverted the serial buffer changes and also cleaned the display code. The stuttering should be gone now but it might be that the filenames are scrambled. Let me know if they are.

Ich habe einen Mega X, da habe ich dieses Display Problem nicht, hat der Mega X etwas noch ein anderes Display? Dafür funktioniert die Pause Funktion bei mir aber leider nicht, habe schon mehre Marlin Versionen getestet. Display bleibt mit"command has been send wait for response" hängen.
Bei dieser Version bleibt das Display nicht hängen, da sie die extensible ui nutzt, aber es werden noch nicht alle Funktionen damit unterstützt. Vielleicht hast Du ja eine Idee woran das liegen könnte?

@Thomas0109

Ist wohl ein Dgus 2 Display verbaut, wie ich gerade rausgefunden habe. Das sollte sich ja dann sogar flashen lassen.

Good morning, i flashed your new release right now. I will make a test print now.
By the way no files from the sd card are shown just the special menu option what is fine for me because of Octoprint.

@knutwurst

@ketchup67 : Files are only shown in the root directory, so maybe this is the issue? When using filenames with a length over 26 characters, the short (DOS 8.3) are used.

@Thomas0109 : Ein DGUS 2 ist es nicht. Höchstens ein Clone davon. Das Display im Mega 3 hat einen USB Port aber keinen cardreader. Außerdem einen Nuvoton NCU120 Prozessor. Das DGUS 2 läuft glaube ich mit einer T5L ASIC 8051 CPU. Flashen kann man es trotzdem, nur bisher habe ich es nicht geschafft einen Firmwaredump zu machen. Und solange Anycubic die Firmware nicht offenlegt oder wir rausfinden, was für ein Display das ist, wird das nichts.

Zu dem von dir geposteten Link ( MarlinFirmware/Marlin#18655 ) kann ich nur sagen, dass "extensible ui" nichts weiter bedeutet, dass man die Funktionen der Marlin Firmware übersetzt und dann die Funktionen des Displays verwendet, um diese darzustellen. Dazu steht bei mir auch etwas in der Readme :) Die Implementierung des "Features" in der Marlin 2.0.6 habe ich mir auch schon angesehen. Das ist ein 1-zu-1 Clone von David Ramiro mit einer Zwischenklasse für ExtUI statt der HardwareSerial Implementierung. Und David hat es komplett von Christian Hopp übernommen. Es ist nichts neues, sondern einfach der Support des i3 Mega Displays in der Firmware.

Schau dir mal die commits an: https://github.com/MarlinFirmware/Marlin/pull/18655/commits

Zugriff auf das Display hat man so leider immer noch nicht.

Was du mit "command has been send wait for response" meinst, kann ich nur ahnen. Du redest von einer Ausgabe im Pronterface oder so? Du kannst nach Pause nicht mehr auf Resume drücken? Ja. Das ist auch ein Bug der Ramiro-Firmware, der scheinbar in die Test-Builds von Marlin übernommen wurde.

Ein Fenster mit "Command has been send, wait for response" steht dann auf dem Display und lässt sich nicht wegklicken.
Mit den commits von jba verschwindet dieses Fenster nach einem klick und ich kann auf resume klicken.

Habe den Mega erst seit Freitag, hatte vorher einen A8, deshalb muss ich mich noch ein wenig belesen wie es mit dem Display ist. Mein Display hat die gleich Bezeichnung wie auf dem Dgus 2 und sieht auch genau so aus. ist wohl anscheinend auch im 4Max Pro verbaut.

Einen Firmwaredump würde ich auch gerne hinbekommen, bevor ich versuche etwas am Display zu flashen.
Hast Du das schon gesehen? Ist aus einem Anycubic 4MaxPro

Wenn das stimmt, sollte es doch möglich sein es über UART auszulesen.

@ketchup67: Thanks for the fedback <3
So does the display work as expected or is something scrambled?

@Thomas0109: Ist es möglich, dass wir auf Github auf englisch schreiben? Einfach damit die community erweitert und nicht durch eine Sprachbarriere ausgeschlossen wird ;)

Es gibt allerdings auch eine deutschsprachige offizielle Facebook-Gruppe, falls du bei facebook bist? -> https://www.facebook.com/groups/3094090037303577/

Zum Thema DGUS 2 ... also wenn es bei dir wirklich so ein Display ist, dann hätte ich gern ein paar detaillierte Fotos. Bisher bin ich nämlich davon ausgegangen, dass das Display von der Hardware her das selbe ist, wie in meinem normalen i3 Mega S - und das ist kein DGUS 2.

Nothing scrambled on the display anymore but files in the root like the standard owl_pair ar not shown

Wow! That is really a completely different TFT! And it really looks like the DGUS II you mentioned!

In comparison, take a look at the original TFT:

Since the Support for the DGUS II Display is implemented, I'll close this issue now :)
