We're rewriting the Marlin website from the ground up as an accessible feature-first User Manual — with an eye towards knowledge embedding and further integration with Auto Build Marlin and that OctoPrint 2 plugin we keep teasing. Exciting time to be an #OpenSource maintainer / web dev!

Before you unleash #Agents on your #OpenSource project prepare and curate all your knowledge. Sharpen it and remove dross and resolve ambiguities. Provide a high level overview first and work towards details subsystem-by-subsystem. Be patient and take advantage of shared skills.

Did #GitHub Copilot powered by #Claude just one-shot the solution for a lost steps issue that only manifests when Input Shaping adds extra cycles to the Stepper Interrupt? It looks that way! I did give it some hints where to look, but with only the vaguest of inklings.

For a test to make sure everything is copacetic I just did this and got a successful build. Of course, various settings would need tweaking, but it works like a charm. The "Auto Build Marlin" tool makes it slightly more convenient.

Auto Build Marlin is continuing to improve! The Config Schema and Custom Config Editor are getting to a pretty good place. Now that it can reliably parse configurations for enabled items we can finally get that Config Migration working and reduce your updates down to a one-click process.

I'm adding some more buttons to "Auto Build Marlin" so you can get straight to the settings you need to define before you build the firmware and flash it onto the machine that you'll use to make the things you need to make. #3DPrinting

Recently we began distributing binary builds for all the example configurations provided by the community. Submit yours to the Configurations repo! Each binary build includes the minimal Config.h file with only the options you need, which you can tweak and use to build a new firmware from source.
