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
For me the responsivity of Klipper UI was reason enough. Octoprint is unbelievably slow on the same hardware. The other thing was ease of configuration - no firmware compilation and flashing necessary. And the third is the actual printing performance - Octoprint has a really bad implementation of the actual print data transfer, and the serial interface routinely chokes on fine data such as arcs. That never happens with Klipper, even at much, much higher print speeds.
