First printer "offline" when adding second printer

[jangrewe]

Dude, this is so awesome! I came across it while searching for projects for the CYD, and luckily had a spare CYD to use for you project - because that's just perfect use of this little screen.

Anyways, my issue: I've set it up for my Voron 2.4, and everything was fine, then i discovered that it can handle multiple printers, so i also added my Voron 0.2. Unfortunately the Voron 2.4 is now always shown as "Offline" (even though it's online 24/7) and i'm "In Control" over the Voron 0.2, with the "Control" button for the Voron 2.4 being disabled.

I'm not sure how to fix this, other than to reset the device and only add one printer... and get a second CYD. ;-)

Oh, this is a CYD2USB (as it's often referred to, because of the 2 USB connectors) with a ILI9342 driver, and i had to invert the colors - maybe that can be set as the default for these boards?

And a final Feature Request: Either a full serial shell or, even better, a simple web interface to manage the printers. Entering API keys via the on-screen keyboard isn't much fun... 😁

PS: Enjoy the ~2 coffees 😘

Hi,

First of all, thanks a lot for the coffees!

Second, you seem to actually have ran into a bug. I don't pass authententication through on the minimal requests done for multi printer mode. I have prepared a build that should fix this issue. Would you mind giving it a go?

Instructions: https://github.com/suchmememanyskill/CYD-Klipper/blob/master/Manual_Install.md
Build: https://github.com/suchmememanyskill/CYD-Klipper/actions/runs/9929717077

Third;

maybe that can be set as the default for these boards?

I'm unsure if i can detect the difference in boards, as the same display driver is used across all 2.8" versions. That's why the toggle is there, though.

a full serial shell

Someone was ahead of you on that idea, see #117 :)

Howdy, those are well deserved!

I just did, and it's working! Thanks for that quick fix 🥳

No worries about the boards, i just noticed that you did have a couple of variants the same board, so i thought this was already somehow sorted out, but with the wrong default... nevermind then, it's easy enough to configure (another example of the awesome job you're doing with this).

see #117

Great minds think alike! 😁
I'll have my fingers crossed that the PR gets merged before you release a new version, because i'd love to avoid entering the API key via the screen...
Oh, but i could enabled OTA, that would retain my config, right?

And maybe this is of any help to you, e.g. for the instructions how to flash a dev image: i'm typically using https://esp.huhn.me/ to quickly test any images without having to build them, or fire up esptool. It works great if you know to flash to 0x0. ;-)

Thanks again!

Updating OTA usually retains your configuration, except if i make changes to the configuration layout (example: i add an option in a breaking way). If there is any breaking changes, i specify this in the release notes.

Also, yeah, releasing this together with the serial configuration is the plan

Awesome, looking forward to it! Already ordered a 3.5" with capacitive touch, and then i'll design a nice case with a 18650 and USB charging.
