I have just got a Creality Ender 3 Pro. I have done a few prints from a microSD card, but I realise I will want OctoPrint!
I have been using various Raspberry Pis for a few years so fairly OK on getting them going.
So I am looking for some recomendations .....
I want to be able to use the RPi to detect a temperature from an 18B20 temperature sensor and switch on a relay. So I need to be able to access the GPIO pins and I would like to programme in Python.
Can I do this if I use OctoPi?
Is there a 5V DC power supply that I can use on the Ender 3 Pro?
If not I will just use a power buck and a "wall wart" power supply.
I will want to add a web cam. I will probably use a Logitech C270, but is there a "better" one?
I see that Octoprint has a web interface, but can I still use SSH and SFTP?
Which RPi should I use? My current guess is that a RPi 3B+ is probably best as it runs cooler, although I also have a RPi 4 that I could use. Which is "best"?
Any constuctive advice would be greatly appreciated
