MarlinConfiguration

Description

This repo contains the Marlin Configuration that I'm using for my Ender 3v2.

My build contains the following:

• BLTouch Clone (3D Touch)
• BTT SKR Mini E3 V3.0
• BTT TFT35 E3 v3.0

I set this up as I was unhappy with my build loop locally, and I can't figure out how (well okay I'm too lazy) to get PIO to dump the firmware right to my board.

I'm an SRE by trade so setting up CI for my Marlin Configuratio was an easy thing for me.

This repo is driven by a Github Action Workflow .github/workflows/platformio.yml, it should be fairly simple to modify for your own use.

It's pretty straightforward, it will only run when the following files are changed on the main branch.

• Configuration.h
• Configuration_adv.h
• platformio.ini

Here is a brief overview of what it does.

1. It gets the Marlin Firmware. https://github.com/CalvinRodo/MarlinConfiguration/blob/82ff4a0017c4fb1a25ae9b0cfde0784ebfe96593/.github/workflows/platformio.yml#L17-L:21

You can configure the branch or tag you want to get by modifying this line:

MarlinConfiguration/.github/workflows/platformio.yml

Line 20 in 82ff4a0

ref: bugfix-2.1.x

2. It then checks out this code and copies it on top of the existing configuration files here:

MarlinConfiguration/.github/workflows/platformio.yml

Lines 37 to 41 in 82ff4a0

	- name: Copy Config Files over
	run: |
	cp -f ./config/platformio.ini ./marlin/ &&
	cp -f ./config/Configuration.h ./marlin/Marlin &&
	cp -f ./config/Configuration_adv.h ./marlin/Marlin

3. It builds using PIO:

MarlinConfiguration/.github/workflows/platformio.yml

Lines 42 to 44 in 82ff4a0

	- name: Build PlatformIO Project
	working-directory: ./marlin
	run: pio run

4. If that is successfull it tags the latest commit on the main branch using the action https://github.com/anothrNick/github-tag-action

MarlinConfiguration/.github/workflows/platformio.yml

Lines 45 to 49 in 82ff4a0

	- uses: anothrNick/github-tag-action@1.39.0
	env:
	GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
	WITH_V: true
	SOURCE: config

5. It will then create a release of the tagged version and will upload the compiled firmware.binhere:

MarlinConfiguration/.github/workflows/platformio.yml

Lines 50 to 53 in 82ff4a0

	- name: Release
	uses: softprops/action-gh-release@v1
	with:
	files: ./marlin/.pio/build/STM32G0B1RE_btt/firmware.bin

You can find the releases here: https://github.com/CalvinRodo/MarlinConfiguration/releases

It should be pretty easy to modify this for your own use, you just need to copy the .github/workflows/platformio.yml file into your own repo at that path, and then commit your configuration files.
