Developer @patrickdoddboy shares his experience using Grok to clean up 3D printer firmware: the model did a decent job, but he read every line before flashing it to hardware that "can burn my house down" — and caught Grok trying to sneak absolute nonsense into his pause function. A good reminder that AI-generated embedded code needs human review, especially on physically dangerous devices.
