Branch to build firmware for BTT SKR Mini E3 V2.0 board

[ckiefer]

Hi @kad
Thanks for this great work! I can see a lot of branches at https://github.com/kad/Marlin. Which of the branches do I have to check out to build the firmware myself if I want to build it for my new BTT SKR Mini E3 V2.0 board?

I am using this tutorial to build the firmware (with VSCode): https://youtu.be/eq_ygvHF29I

Cheers, Christoph

For SKR Mini E3 board, you should use same settings/build parameters as for SKR mini MZ (those are identical schematically boards with different physical dimensions).

For VSCode, use build target name one of those: https://github.com/kad/Marlin/blob/anycubic-kad-bugfix-2.0.x/kad_anycubic_mega_zero_default_envs_release.ini#L86-L110

Please note, that majority of youtube tutorials are not applicable to the way I did dynamic build flags to have single set of configs. You can use that tutorial to install VSCode and PlatformIO plugin for it, but then you need to understand at least basics of C/C++ syntax and how PlatformIO works.

@kad Many thx.
Just to clarify, I would use this branch: https://github.com/kad/Marlin/tree/anycubic-kad-bugfix-2.0.x, right?

I am software engineer, so familiar with coding, but still, I have never worked with these tools before. If I understand correctly, I would still not be able to build the firmeware for this board using your branch and the approach shown in the video?

Yes, branch is correct.

I haven't watched video. Sorry, allergic to the ads and all businesses built on top of ads.

If you are using VS Code, just make sure that you specify correct build target from PlatformIO list of targets.
Something like on following screenshot:

@kad I realized that there is a build target for anycubic_mega_zero_btt_mini_bed_bl but no target for anycubic_mega_zero2_btt_mini_bed_bl (for an Anycube Mega Zero 2.0 with a heated bed)?

Very basically, if I want to change the mesh size (for auto-bedleveling using a BL touch), how would I address that using your brilliant work?

[kad]

There is no such target as all MZ2 targets assume that heated bed is needed :)
so, use anycubic_mega_zero2_btt_mini_bl
