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.

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.

Board for a 3D printer: choosing a control motherboard

When buying or assembling a 3D printer with your own hands, special attention should be paid to the device's motherboard. Since this component is responsible for printing products in general. Consider what functions the motherboard performs, what types of this component exist, and what parameters you need to pay attention to when choosing it.

3D printer motherboard

The controller motherboard is the main control element for the extruder, motor, sensor and heated filament bed in any 3D printer.

Motherboard is executing user-specified commands. After the internal set of microchip elements converts electrical impulses into mechanical movements of stepper motors. As a result, a three-dimensional computer model will be printed layer by layer on the working surface of a 3D printer.

Choosing a control board

Among the most popular motherboards for 3D printers, there are five models:

1. Arduino Mega 2560 + Ramps 1.4.
2. Melzi.
3. Lerdge X.
4. Duet.
5. Rumba.

Let's take a closer look at the features, pros and cons of each board.

Arduino Mega 2560 + Ramps 1.4

Board with Ramps 1.4 component operates from 5 V. It is equipped with five slots for installing stepper motors. At the same time, three slots allow the motors to control the axes of the printer, and the other two to drive the extruders. In addition, the board contains many additional pins for controlling various elements, such as a table auto-level sensor, axle limit switches, servos, etc.

To control all the printer's built-in electronics, the board contains contact pads into which the Ramps shield component is inserted.

The three main advantages of the board are:

• low price;
• a wide range of interchangeable components that can be replaced in the event of a breakdown;
• additional pins for controlling various printer components.

The board has only one significant drawback - its bulky design.

Melzi

The Melzi motherboard is equipped with four stepper motor controllers, three of which are located on the XYZ axis and one on the extruder. This model is sold already with customized firmware. Therefore, the user only needs to correctly connect the wires to the output connectors.

You can print 3D objects using a memory card via a micro-USB connector or by connecting the card directly to a computer.

The Melzi board is ideal for the beginner building a printer for the first time. Since it does not require additional calibrations and can be used immediately after purchase. However, the motherboard also has significant drawbacks:

• no display can be connected to the board;
• You can reflash the motherboard only through the ISP port, but this will take a lot of time and a layer of special knowledge;
• If the motor controller fails, it cannot be replaced.

Lerdge X

Lerdge X is a motherboard with a 32-bit STM32F407 chip that allows you to quickly read lines of code. The device is additionally equipped with four drivers and a color display with touch control. The board supports only one extruder and it is not possible to install a second one if necessary.

Before using the board, you need to calibrate it, set the dimensions of the working area, adjust the temperature sensors of the extruder and table, and set the speed parameters of each motor.

You can print files using a flash drive, memory card or via a computer.

Pros of using the Lerdge X board:

• motherboard fits any type of printer;
• board chip supports various kinds of popular slicers;
• built-in display with touch screen.

The disadvantage of using the board is that only one extruder can be used.

Duet

The Duet board is equipped with its own open source firmware, which is available for free to any user on Github.com. The 32-bit Atmel SAM3X8E chip is responsible for the stable operation of the motherboard.

Built-in device drivers allow four extruders to print simultaneously. For more convenient control, the user can install a touch screen with a diagonal of 4.3, 5 and 7 inches.

Pluses of the board:

• free firmware;
• four extruders available at the same time;
• two board configurations to choose from (Ethernet or Wi-Fi).

Duet motherboard cons:

• Before installing the board, it requires full configuration and firmware.

Rumba

The Rumba 8-bit motherboard allows the 3D printer to use three extruders at the same time. However, installing them separately will not work, but you can only install a Diamond Hotend multi-extruder with support for three filaments.

This type of board is based on the Arduino processor. It comes with Marlin firmware installed. If the user needs to reflash the board, then for this you can use the standard mini-USB connector.

Among the advantages of Rumba are:

• the presence of connectors for connecting a display and a slot for a memory card;
• removable motor drivers that can be easily replaced if broken;
• simple flashing if necessary.

The main disadvantage of the motherboard is that for printing with multiple filaments, you will need to purchase an additional multi-extruder.

What to look for when choosing a 3D printer board?

When choosing a motherboard for installation in a 3D printer, the user is advised to pay attention to six device parameters:

1. The number of supported extruders. Ideally, there should be four or more. In this case, full color printing will be available.
2. Integrated or plug-in drivers. It is desirable that the drivers in the board are removable. Since in the event of a breakdown, they can be easily removed and repaired or replaced in the event of a complete malfunction.
3. Number of engines. It is recommended that the board has at least four motors, ideally six.
4. Wi-Fi available. The built-in module will allow you not to constantly connect the printer to the computer each time you print.
5. Firmware support. It is desirable that the board supports various types of firmware. Both paid and free.

   Help. Each specific type of board can support one or more types of firmware. Their number depends on the board manufacturer. For example, Arduino boards support Marlin, Marlin Kimbra, Marlin RichCattell, Repetier-Firmware, Teacup, Aprinter, Sprinter firmware. Arduino Due motherboards can work with Marlin4Due, Marlin Kimbra v4.2.x, Repetier-Firmware, RepRap Firmware. And 32-bit ARM processors are compatible with Smoothie Project and Redeem firmware.

6. The presence of protection against incorrect inclusion of elements.

In this article, we have listed only the most popular motherboards for 3D printers. However, on the electronics market there are boards for any user requests, the choice of which can be guided by the recommendations presented above.
