The Main Differences Between Klipper and Marlin


A 3d printer is just a machine composed of a stepper motor and metal. It is firmware that makes it lifelike. The firmware reads the G-code from the slicer and converts it into an electrical pulse that controls the printer, resulting in an extrusion with a significant level of detail.


There are multiple options for 3D printing firmware, including RepRap, Repetier, Marlin, Klipper, and more. Marlins are undoubtedly the most welcomed of the 3D printing industry, but Clipper has emerged with various unique features.


Marlin was developed by Eric van der Zam for Ultimaker in 2011 and dominates the market and it appears in most FDM 3D printers.

Klipper was first released in 2016 by Kevin O'Connor, achieved computationally intensive and precise control, which means faster printing speed and higher printing quality.




If you want to change Marlin's configuration, you need to change one or two configuration files and tell the compiler what is required to build the firmware.


The configuration of Klipper is stored in editable text files that are read every time it is started. Modifying these files is relatively easy, and since there is no need to refresh the controller, configuration changes can be made quickly.


Integration with Add-Ons


For many users, Marlin and OctoPrint are a powerful combination that provides built-in features for controlling 3D printers and remote monitoring using real-time cameras.


Klipper's dedicated user interfaces, such as Fluid and Mainmail, provide a rich browser based control panel that displays information about ongoing printing and allows users to change Klipper and printing settings. In addition to other features, additional features such as the OctopPrint plugin and support for webcams are also provided.



With the continuous development of the 3D printing world, both Marlin and Klipper are constantly evolving and improving. So today, what is the right choice? However, the answer depends on multiple factors.


The Marlin 2.1+on a 32-bit motherboard has the processing power required by the vast majority of 3D printers. It is relatively simple to install and configure, and provides functions that meet almost all printing scenarios. It appears that it will continue to be the default firmware choice for printer manufacturers.


Klipper was initially more complex to set up, but subsequent configuration changes were easier and faster. It also supports unique features to improve high-speed printing quality. For those seeking to improve print quality and speed, or those who are building or modifying temporary printers, this is undoubtedly a very attractive choice.
