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

    This might be situation dependant, but I personally (Ender 3 S1 Pro) spent weeks searching for ready-made firmware, then learning how to modify and compile firmware, then troubleshooting why I couldn’t get Linear Advance working, only to finally figure out that it just plain wasn’t supported by Marlin on my hardware.

    I was about to give up and just go back to the stock Creality firmware, but decided to give Klipper a go without really knowing the full capabilities, other than that it natively supported Pressure Advance. In a fraction of the time I had spent dicking around trying to get a single feature enabled in Marlin, I had my printer running off a slick web interface, fully tuned up and printing substantially better than I was able to achieve with Marlin.

    Now, granted, I never tried to get up and running with Octoprint so I probably am only half answering your question, but as a relatively casual printer I have found using and tweaking Klipper to be substantially more straightforward, and would not hesitate to recommend giving it a stab as long as you have a RPi laying around already.

      Yes one of the big advantages of klipper is that you don’t need to recompile the whole thing to make changes to your configuration. You just edit it in a text editor and then save and restart the firmware.

      I also haven’t used Octoprint, but other advantages for klipper over marlin are the ability to control your printer via a webUI, pressure advance, resonance compensation, easily add cameras, mesh leveling visualization, and a bunch more that I’m forgetting off the top of my head.

      I did exactly the same thing as you. I like the built in web management in klipper so much more than octoprint.
