The controller board is responsible for all of the electronic functioning of a 3D printer. Without it, the printer wouldn?t be able to do much more than turn certain components on and off at the manual flick of a switch.


Controller boards handle all the logic behind 3D printing, such as parsing G-code files, regulating temperature, and most importantly, controlling motion. The latter is specially important if we? 3D Printer Controllers re discussing FDM and stepper motors.

Whether you?re considering an upgrade or simply replacing a broken part, selecting the right controller board for the printer isn?t probably the most straightforward task. Since there are so many brands and models available today, we?re here to help! Read on to look at some of the best 3D printer controller boards available.

What started as a landscape of bare-bones boards trying hard to simply get the job done has turned into a packed marketplace of technological beauty. Controller boards have not only become more powerful but also more diverse, offering new features which were moving the 3D printing industry forward.

Our selections in the following paragraphs are primarily based on two considerations:

Performance: Open-source 3D printing firmware is in constant and rapid improvement, with new features periodically released to improve our machines? capabilities. Hardware is slowly catching up, and whether you?re likely to replace or upgrade your board, it?s probably a good idea to get a powerful processor that?ll manage to handle the advancements of the next two years at least.
Popularity: For the uninitiated, changing a 3D printer?s controller board might sound like brain transplanting. Well, it?s nowhere near that hard, but configuring new firmware and figuring out all of the connections and modes can feel a little overwhelming. That?s when a good user community will come in, with troubleshooting tips and even preconfigured firmware. Moreover, popular controller boards are popular for a reason, and that reason is normally reliability.
