Detail how to hook up relay #1

Closed challgren closed 5 months ago

challgren commented 5 months ago

I was reading the docs and I can't understand how to hook up the limit switch to the relay. Can you detail this or provide a photo?

Thanks!

3DCoded commented 5 months ago

Sure! I have added a document explaining how to hook up the limit switch, Chameleon, and RPi to the Relay. Note that this uses a Relay shield as I don't have much experience with normal relays. Here is the link: docs/wiring.md

If this answers your question, please close this issue. If not, please tell me what I can do to help answer it more clearly.

Thank you very much! I don't have the kit just yet but I've been researching on how to use it with klipper and my first thing was to get rid of the physical button but I didn't know how people achieved that. But thank you that clears my issue up and should help others on their journey.

After reading the 3d chameleon forums you can directly hook up to the raspberry pi by inverting the pin and connecting green to your gpio and black to a ground. 2.0v+ will trigger the chameleon. But thank you for the guide.

Thank you. I didn't see that. I will experiment with that to see if any changes would need to be made to the plugin/documentation.

The biggest would be inversion of the pin. I was using your script and the dependency on the filament sensor is kind of a deal breaker right now. Also having a lot of config file parsing issues.

3DCoded commented 5 months ago

I have updated the documentation (the Wiki) on how to invert the pin, but the filament sensor is needed for reliability reasons (the entire plugin is built around a filament sensor). What kind of config file parsing issues are you running into? Can you post your error messages here?

3DCoded commented 5 months ago

I can add support for not using a filament sensor, but that would reduce the reliability of the system.

3DCoded commented 5 months ago

I just added experimental support for disabling the filament sensor, which can be used by setting filament_sensor_name: disabled.
