I actually have Marlin + Octoprint but found out recently that Klipper exist. I read everywhere that Klipper is better but I don’t really get why. I understand that Klipper use raspberry as powerfull calculator instead of the STM32 of the printer, but octoprint is used to send Gcode to Marlin too… So what’s the really difference please?
Edit : I don’t understand how Klipper or Marlin can give better results when gcode and instructions are generated by Cura
There is an add-on that lets the E3v2 screen work with klipper. I have it working and while the feature set is a bit limited its enough to see the print status and start a new print (among other things). You just need to run 7 wires from the screen to the GPIO pins on the pi. I used a front panel cable from an old PC case to accomplish this. Check it out!

Ah, nice! I started implementing the same thing a long time ago but got bored making all the UI screens after I had coded the basics :)
