Describe the solution you'd like

Hi,

This is an extension of #439. The Feature request is for the support of flashing MCUs via Katapult, I suggest taking it further. We can automate the MCU flashing. I am helping in Voron Discord can-and-usb channel and we have an extensive experience with flashing MCUs to all imaginable boards.
The Esoterical Guide already has configurations for the vast majority of MCUs. We can create .config files for all of them, so in the KIAUH, the user will have the option to specify MCUs make and models, and the script will build the Katapult/Klipper with KCONFIG_CONFIG=config.MCU
Since KIAUH has access to printer.cfg it can invoke the Katapult and flash the MCU via CAN with minimal user input, or even no input, if we can save a .config for each UUID.

If that sounds interesting, please stop by the Discord channel; we can talk about details.

Hello !

I'm a computer science student majoring in networks, and for one of my courses I need to contribute to an open-source project by submitting a new feature and two bug fixes. Since I'm already a Klipper user, I immediately thought of this ecosystem — and KIAUH in particular — as the perfect fit.

I've contributed to the Klipper community in the past and have been tinkering with 3D printers for years. I currently run two CAN bus printers (a Voron 2.4 and a Voron Trident, with an SB2040 and an SB2209, both using different versions of the Octopus Pro board). Over time, I’ve run into and solved quite a few setup issues, including some related to newer Linux kernels on RPis.

I’m not a master programmer, but I’m very comfortable with this environment and eager to learn more. I’d love to help implement this feature if you’re still looking for someone to take it on.

@SergeDubovsky would you be open to me following up on this feature? I can head over to Discord If you'd like?

@dw-0 would that be okay ? Is there a preferred way to contact you regarding other issues I could help with?

Thanks a lot for your time!

@theogayar I am not currently actively involved in Klipper/Voron. Too much job-related work. But I will keep an eye on the progress :) Thank you!

Hi, generally it's very welcome when people offer to take over some feature requests or want to fix bugs. Keep in mind, that i cannot really support on topics that require specific hardware i don't have available. Thats where this project really requires the help of the community :)

Best way to contact me is here, in this repo. Im also available on the official Klipper discord.

Thanks for both of your replies, I'll start working on this in a fork of the repo, and will make sure to test on my hardware to ensure everything works as intended before submitting the pr.

I'll keep you posted through this issue if that's okay ? @SergeDubovsky I don't know if I'll be able to implement everything you suggested, but I'll do my best and might try to reach out through Discord along the way for input if that's okay?

About testing, I've got my two machines, but that might no be sufficient. If some people are willing to help by providing feedback, please let me know here too !

I would like to test PR if something pops out from under @theogayar keyboard.

I have Voron 2.4 and Big Tree Tech Eddy USB. That would be handy to also flash from KIAUH as well without partial dissasembly

Edit:
Today I've learned that Klipper has option to jump to bootloader without disassembly. So I no longer have need for that. And thus wont test.
