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
I’ve been looking into using an old Android phone as a display/control screen. The only thing holding me back is that my spare device (Note 4) doesn’t have pass-through charging and won’t run off a charging cable without the battery installed. This can be bypassed by attaching a couple wires to the pins where the battery connects but I’ve been too busy with other stuff to do it.
Might be an option for you if you have one laying around. Many newer phones can run without a battery just fine.
