I’ve been trying to get klipper to run on atsamc21, so I can use Duet3D Toolboards with it. I can’t seem to establish a connection over CAN bus though.

I am having a hell of a time getting a stupid Spring Boot project off the ground. I have no idea why the application isn't finding the Controller classes and autoconfiguring them so I can do a simple GET /foo.

For whatever reason, the spring-boot-starter-actuator is configured properly, so I can GET /actuator just fine.

Debug logging is showing that none of my controller classes are being found for autoconfiguration, which originally lead me to believe I had my package structure incorrect, but following the advice found here but that didn't help at all. Nothing changed in the structure, or the debug output in the logs after that.

If anyone has (probably less than 5 minutes) of experience to donate and show me what the hell I'm doing wrong, I would very much appreciate that. I feel like a freshman back in CS 101 again 😅 Link to my github project

  Using the instructions for running using Gradle:

  Then visit http://localhost:8080/foo and I see "Foo" in Firefox.
