- Successful/failed builds: please file a GitHub Issue with explanations and photos
- Code changes: to maximize the chance of your PR being accepted, discuss the planned change beforehand
- Only make the necessary minimal edits
- Run in the
TESTmode, add new tests if needed - Split unrelated changes into separate PRs
- PCB changes: please open a new GitHub Discussion
- 3D models: in most cases, don't edit the model, add a new file. PNG preview and a dimension would be nice too.
If you're willing to manufacture this device and/or sell it as a kit, we'd be happy to link to your page for free - especially if it makes the build cheaper than buying all the components separately.
