Buyer’s Guide
Above we have listed some of the best 3D printer controller boards available.
But what if you want to look for more boards? What exactly do you look for in a 3D printer motherboard, and how do you select one for yourself? Here are a few pointers that you need to keep in mind.
Firmware Compatibility
Firmware is the software on the 3D printer controller board that is responsible for all calculations and commands to the printer hardware. There are many different types available, for example, Repetier, Prusa, Klipper, and Smoothieware.
Recommended:
Creality Sonic Pad Review: A Klipper Solution That Needs More Work
Each one is designed for a slightly different purpose, and you need to keep in mind your goals with the machine. For example, if you want a high-speed 3D printer, Klipper is the best choice for you. Marlin and RepRap are the go-to options if you want well-documented and widely used firmware.
You need to consider the choice of your firmware beforehand to select the best suitable controller board for yourself. Make sure there’s enough documentation and support available with your combo so that if you run into any issues, you can quickly sort it out.
Processor
3D printers either have an 8-bit controller board or a 32-bit board. An 8-bit board is cheap to manufacture and provides all the basic functionalities you would expect from a 3D printer. However, it comes with low onboard memory, and the lower number of bits means that it can process fewer calculations at a time, thus significantly affecting its speed.
32-bit motherboards operate at a higher clock speed, have a slightly greater onboard memory, and execute calculations at a much higher rate. They’re compatible with more I/O ports and communication interfaces, and all of these translate to a more feature-rich 3D printer motherboard.
If you want a basic 3D printer with limited functionalities, 8-bit boards are an option. They’ll save a bit of money, and you won’t have to pay for things you won’t use. However, if you want your 3D printer to be future-proof, have advanced functions, and print faster, a controller board with a 32-bit processor is vastly superior.
In our list with the best 3D printer controller boards above, we have only added 32-bit controllers. We believe that an 8-bit board is not worth buying and a 32-bit board is always the better option.
Communication methods
The most basic method of communication on a 3D printer motherboard is a USB port. A USB serial port allows you to control your 3D printer via a USB connection with a computer.
Wi-Fi and Ethernet ports are other methods of communicating with your 3D printer. An ethernet port would allow you to control your 3D printer over a local wired network.
Wi-Fi connectivity would allow you to control your printer wirelessly. One benefit of Wi-Fi is that you don’t even have to be present in the same room as your 3D printer, and you can control it remotely from anywhere.
Low-end controller boards don’t come with Wi-Fi and Ethernet ports; some might have pins for attaching external Wi-Fi modules, though. A USB serial port is enough if you want a basic 3D printer.
If you want wireless 3D printing or operate many 3D printers simultaneously, you should consider getting a Wi-Fi-equipped controller board.
Connectors
Aside from a USB port, there are many other connectors (or headers) on the controller board. These are used for a wide variety of purposes. Endstop connectors, hot end heaters, stepper motor connectors, bed leveling, and filament runout detection sensors are some of the few.
A well-specced-out controller board like the Duet 2 Wi-Fi or the Duet 3 6HC will have almost all of these connectors and then some more. Connectors allow you to interface various devices with your 3D printer, providing additional functionality.
The more connectors your controller board has, the more expensive it will be and take a lot of space. You need to know what features you want in your 3D printer and select the board with the particular connectors to get the maximum benefit.
Stepper Drivers
Stepper motor drivers affect the size of the stepper motors you can drive in your 3D printer and the sound levels you hear in the process.
On most 3D printer controller boards, stepper drivers can’t easily be swapped out. Therefore, selecting the right kind of controller board with the right stepper driver is essential.
Basic stepper drivers like the A4988 are cheap, easily accessible, and provide a relatively good experience for basic 3D printers. They do drive stepper motors loud, are unreliable, and can only provide the steppers with limited current.
TMC drivers, on the other hand, are known for their silent operation and current-carrying capacities. The TMC 2xxx series are rated at 2A peak current, while the TMC 5160 typically offers 3A to 4.4A on 3D printer controller boards.
You need to consider the microstepping capabilities of the stepper motor drivers as well. Microstepping divides a full step into smaller steps. The smaller the step, the higher the resolution and the smoother the vibration. As a minimum, you want 1/16 step microstepping, but the best 3D printer controller options offer up to 1/256 step
Touch screen support
A touch screen enhances the functionality and ease of use of a 3D printer by making navigating the menu and dialing in the various features easier.
Not all controller boards have touch screen support built-in. While choosing a controller board, look at the connectivity options and the compatible touch screens. You need to make sure that the board’s firmware supports it, and there is at least a little bit of documentation on how to interface the controller with the touch screen.
FAQ
What is a 3D printer controller board?
A 3D printer controller board is a piece of hardware that controls all electronic components in a 3D printer. It is responsible for motion, temperature control, and reading all commands from GCode files.
Why upgrade your printer’s stock controller board?
As time passes, the current features in your 3D printer start to seem obsolete. A controller board upgrade will give you access to many advanced features, allow for added functionalities and enhance your overall 3D printing experience.
Is a 3D printer controller board the same as a 3D printer motherboard?
Yes, in the context of 3D printing, the terms ‘controller board’ and ‘motherboard’ are used interchangeably.
They mean exactly the same thing.
Conclusion
The best 3D printer controller boards are the ones you’re able to afford and will work with your 3D printer. With so many options on the market, it can be tough to choose just one. The important thing is figuring out which one of these top-rated controllers would be right for you.
In our opinion, the Duet 2 Wi-Fi is the overall best 3D printer controller board that you can get right now. Despite its high price, the Duet 2 Wi-Fi ticks all the boxes in terms of features, connectivity, upgrades, and ports. It is designed to be a universal solution for all types of 3D printers and can serve as an effective replacement for practically any board.

Selection of a controller for a 3D printer. STATTIS "3DPLAST-Vobron Plastic for 3D Druku"
Principle of Roboti 3D printer
є Bezlich technology, Vikoristovoye for the foundation of 3D princhi, Ale Vanya Prynovanii on the Otrynovani on the Laznovanii in the Lear digital model. This technology is practically priceless when folding folding models or spare parts for repairs. Those who previously had to work at a virobnik factory can now work independently in the shortest terms. Obviously, for the preparation, only the songs of the victorious plastics are still being made, but the assortment of the vicarious syrovina is gradually expanding.
Controller function In fact, the printer’s command post is the key to the flow of water with the removal of the “brain” instructions. In fact, the controller is all the signs of a computer - it includes a processor, operational and permanent memory. Sometimes you can work on your own, taking into account the necessary parameters of the 3D model from the memory card. A single exchange - there is only one program in the computer.
Types of controllers
In fact, at the moment, all cards have two types of controllers - 8-bit and 32-bit.
Most early printer models were controlled by Atmel 8-bit controllers. Vtіm, tse buv laying in the distance is an option that vin zastosovetsya to tsikh fіr, being inextricably tied to the Arduine platform. If you add an addendum, you will be able to add your own program to the firmware of the 3D printer on your own.
Advantages
- payments based on 8-bit controllers based on the Arduine platform work without problems with the main modern machines;
- platform code allows you to easily add and change robotic printer programs;
- Arduine firmware is ready, in which you can easily adjust the necessary parameters for your printer and start working.
Shortfalls
- stinks are charged according to the swidcode and crochet to the bigger inspectors.
The development of technology called out to the life of 32-bit controllers. The Arduine platform was preparing firmware for the version of the controllers, but more importantly, the Smoothieware platform has been introduced, as well as propagating the code.
Advantages
- more prospects for development with increased mobility;
- allows you to program more smooth and fast speeds, supporting more deep planning of the model;
- Firmware Smoothieware has a unique microSD memory card in its memory capacity, on which you can easily edit the configuration file;
- oskolki code vodkritiy, a lot of valets allow their payments to be sent to the rozakhunka for the Smoothieware firmware;
Undersized
- delta printers only work with 32-bit controllers;
- the price is not twice as much, but more expensive than 8-bit ones.
Really insulting to see the controller functioning at this stage of development of a 3D-other is equally good, there are plenty of shards for most printer models of an 8-bit controller. Firmware options are too rich, especially for Chinese manufacturers, but when there is a large number of open codes, there is no sense to take closed pay.
Delta printers with their own folding mathematics, other printers with 1/32 micro-stepping and graphic displays have successfully switched to boards with a 32-bit controller, which means more memory and more computing power for folding. Tim more, that it is possible to change the firmware with the same Arduine firmware, only already under 32 bits.
It's good to know that the code you send often receives surprises from independent retailers, so you can't help but rejoice at the appearance of Klipper software on the market. This method is to increase the brightness and speed of each other both on 32-bit and still on 8-bit controllers. And with help, it is possible to remove the increase in speed to each other by 2-3 times.
Types of inspectors for assemblers
Many well-known computer technics inspectors are engaged in the issue of inspectors. The most popular is the Arduine Mega. Controllers Arduine Mega 2560, MKR, Nano, Uno and others are circulating in Italy and China replicas.
There are no such grandi, like Texas Instruments, and STMicroelectronics, they regularly release new ones, and often in three options - a board is ready, a board is naked and a set of parts for self-assembly. Leather choose the option to your liking.
