I like this. Whilst I don’t really feel a need for it mounted to my tool head, I do like the idea of having it as a remote!

I copied the firmware folder into the vscode explorer, but my window does not show the output section where yours says that the project was successfully updated. What do?

Also where are you finding the two different versions of Knomi? You have some tabs at the bottom of your window you click on, but those are not present in my window either. What do?

I just have checked everything from scratch and it works perfectly fine. Make sure you have VSCode with PlatformIO plugin installed before you drag Knomi folder over VScode, without plugin nothing will build. Make sure you downloading firmware branch cus other branches contains non firmware files. Follow exact steps mentioned in the video.

May be something is wrong with the firmware you already have on the board. I would try flashing it via USB instead of using OTA. You can do it directly from VStudio by connecting KNOMI while holding boot button, device will get in DFU mode and then you will be able to flash it directly. Check documentation to verify. I had to do it with my KNOMI V1 as It was on old firmware without OTA support.

@@georgedunn7573This error is related to cable or usb port, some USB-C cables are power only, try different cables. I would start 1st from compiling plain firmware from BTT repo code and uploading it to verify your VSCode environment works properly, may be some assets you are using too big for the memory of the device. Make sure you have picked correct device in your VScode environment, maybe you are trying to flash wrong Knomi version firmware over wrong device.

Hello! I'm trying to flash Knomi v2 but unfortunately nothing works! The firmware is built in VS code using the platformIO , but when I flash the screen is always black, I tried different firmware, all the firmware that is built through PIO does not work! I tried to flash the firmware built by PIO via USB, and flash_tool did not work! To restore Knomi after firmware failures, I use Flash_tool and flash the Bin file from the official website! I've already tried everything and can't figure out where my mistake is??? please help

When you flash original firmware from BTT GitHub repo does your device works?

@@hobbyistnotes Yes, if I flash the firmware from github via the web interface, everything works! but as soon as I build it myself without changing the source data, nothing works through Vs code

So I am not going to say that this is useless or pointless. I honestly don't feel like the weight is an issue either. I am just going to say I would rather have a large touchscreen somewhere else. But that's the beauty of an open-source project like the Voron. You can customize it however you want. And even if you aren't an expert there are plenty of options out there that companies like bigtreetech have made so you can integrate it relatively easily

Unfortunately those companies for some reason still can't make simple budget capacitive screen with good working touch.... current resistive tft screens are horrible...

@MaheerKibria 6 ай бұрын

@hobbyistnotes define budget. The BTT HDMI5 should work with a voron, and it's like $45. It's not the cheapest thing out there, but it's not that much more expensive than a KNOMI v2

@@shaunmorrissey7313 Definitely not necessary by any mean, but at the same time I feel like it can be one of those things most people think useless and than some one comes out with a very smart way of using it, so I am kind of opened for such experiments.

And by the way I don't really give a damn about the weight. I still think it is generally useless. The only use case I saw for it was in a tool changer setup. Glancing at the screen to show the nozzle temperature while it's on standby. Using it as a controller is moderately useful but at the same time there are much more convenient ways to control it. Web interface, mobilraker, klipper screen somewhat.

If we look at this item from technical standpoint it's somewhat useless and more of a cosmetic toy.
