Creality CR-6

[KoenVanduffel]

I am trying to use your screen software on a Creality CR-6 screen. Though it's a DWIN screen with the same resolution (mounted 90° rotated) It only partially flashed. Only the .BIN .HZK and .LIB files load. The .CFG and others do not load. I assume that though it's seemingly the same screen it is really not exactly the same. It is near impossible to find information though as to what is the difference and how to deal with it. The CR10S pro screen is a T5UID1 the CR-6 one T5UID2 (the only reference I can find). For the CR-6 the .CFG file starts with T5LC1 (taken from the CR-6 community firmware) vs T5D1 for your firmware.

Is there a (easy) way to port your firmware to this screen?
I had a look at the DGUS_TOOL_V8.0.1.1 which is used for the CR-6 community firmware but this is quite a daunting thing to get started with and i could not find any reference to different screen types apart from a resolution setting.

Please never flash your touchscreen with files that are not made for it (unless you don't mind bricking it)...

I'm unaware of how T5L screens work, how they differ from T5UID1 screens and if there's some way to "convert" firmwares between the two.

If someone with enough time, the appropriate skills and proper understanding of these screens and this project wants to submit a PR, I'm all for it. Until then, I'm afraid these screens won't be supported.

Thanks for the quick reply.
I thought they were the same screens so gave it a try... Would not have been a disaster if it got bricked as I have moved to Klipper anyway.

Yeah documentation of the screens seems really poor, at least I could not find much more than what is lined in the CR6 community firmware GitHub. I assume you also used the DGUS V8.0 (or other version ) to produce the screen firmware. There should be somewhere where the screen is defined. ON the CR6 Community GitHub and on the Discord there are a few people with quite a bit of knowledge. Hence I assume I can get started.

link to some of the CR6 screen firmware info: https://github.com/CR6Community/CR-6-touchscreen

I found in the meantime the CR10S pro GitHub which lists the DGUS V7383 as the software to use. It uses a different project file extensions (thats Why I though what you share is not actually the source code). Will have a better look at that.

Hello,
I have T5L1 display ( Sermoon D1 ). I have to compiled source code in SW ( DGUS_Tool_V8.2.1.14 ). Now it is working. I used original T5L.cfg file, generated new bin files, recompiled icons, buttons, screens.

With a tip from the CR6 Discord I managed to install the firmware and get the boot screen correctly. After booting the screen gives 1 beep and goes to a second screen with just the hamburger menu. When I power the screen not connected to the printer it stays on the intro screen which indicates there is communication with the mainboard.

From what I can see i have made a new .CFG file to match the T5L screen and set the rotation. The rebuilt the icon libraries and placed them in the correct positions (following the guide on the Community firmware GitHub https://github.com/CR6Community/CR-6-touchscreen). I assume I did not make mistakes here.

I did not regenerate the .HZK font library as I didn't know which font(s) to generate. I threw in the one from the Community firmware but that doesn't make any difference.

Is there a kind of compile step necessary or is that what the DGUS software does upon saving (generate)?

DGUS Tools generates the binary files for the touch and display controls (and the binary file for RAM initialization) for T5UID1 screens.

I think I figured out where I went wrong. I was confused in the two versions and the fact that they have different Klipper versions behind them (impressed by the long list of customization options in the new version!) but it caught me out. I will revert to the older version which is a "plain" standard interface as far as I can see and get that working to get the principle right before upgrading to the new version.

I switched to your older version DGUS-reloaded-Klipper to figure out the process. I managed to get things to work albeit am missing the touch actions (did not check whether temperature inputs or the like work). Temperature and setpoint reporting from the printer works nicely on the T5L screen on the CR6 now.

When I open your original project in the 7.383 version of DGUS I also do not see the touch commands (page switching is -1 everywhere). Any idea what I am doing wrong?

The font file I left as your original and for now seems to work correctly. If I do run in issues which font(s) and sizes have you used?

[KoenVanduffel]

Just a progress update: I managed to port the graphics and screen navigation to the CR6. The temperatures and so are sent from the printer to the screen. However I cannot give any command from the screen. For instance when I set the hotend to 50 it will just stay at 0.

For the printer mainboard I compiled the firmware with enable DGUS T5UID! screen on and tried both USART1 and USART2. In both cases the temperatures are reported as expected on the BTT CR6 board. Making any setting however doesn't work.

Not having any experience with this software I have no idea where to start searching...
