I would like to develop a plugin for OctoPrint that can use the GPIO pins on a Raspberry Pi 4 to control stepper motors.
My first question is whether this is feasible, and secondly, do you have any tips on how to get started?

Yes, it is certainly feasible to develop a plugin for OctoPrint to control stepper motors using the GPIO pins on a Raspberry Pi 4. OctoPrint provides a robust API and plugin system which allows you to extend its functionality.

To get started, you can follow these steps:

  1. Familiarize yourself with OctoPrint's plugin development documentation: The official OctoPrint documentation provides a comprehensive guide on developing plugins. It covers the basics of creating plugins, integrating with the API, and handling events. This will be crucial for understanding the OctoPrint architecture and how to interact with it.

  2. Learn about GPIO programming on Raspberry Pi 4: Since you want to control stepper motors using GPIO pins, you need to understand how to interact with the Raspberry Pi's GPIO interface. There are libraries like RPi.GPIO that simplify GPIO programming in Python. Explore relevant documentation and examples to gain this knowledge.

  3. Design the plugin structure: Determin...

you could also decide to use klipper, then you can use the GPIO pins pretty much the same way you would use the pins on the printer board and at least get a lot better with the timing

If you wonder, I am building a "slider" that pushes the finished print down the heat bed and a friend builds a multi-filament case. I thing, sync won't be a problem.

yeah, that sounds like something where you wouldn't need perfect sync, you can just wait a few seconds on every side
