2022 A Complete Guide to The Best 3D Printer Firmware
ADVERTISEMENT
The word ‘Firmware’ is not to be afraid of. It is a simple program, like Firefox and Chrome that links software with the hardware. It translates input from the software into an output that the hardware can understand.
For example, the USB controller has firmware that allows the chip to receive information from the USB drive and convert it into a container that can be easily understood by the window explorer.
In 3D printers, firmware understands the ‘G-code’ sent to the slicer software by the user and translates it to the stepper drivers that control the motor, heater, flow, speed, and display, etc.
For example, the given G command ‘G1 X 20 Y 10’ to the software is translated into a set of instructions understood by the stepper. Thus, the extruder reaches X=20 and Y=10.
In this article, we will list down the top 3D printer firmware in detail to make it convenient for you to choose one from different options available in the market.

A Guide to Choosing Firmware for Your 3D Printer
3D Insider is ad supported and earns money from clicks, commissions from sales, and other ways.
Amidst all the bells and whistles of 3D printers, it is easy to overlook the importance of the programming that lies within the hardware. The firmware of a 3D printer is basically what gives it life. It interprets the G-Code generated from the slicer and sends out instructions to the various hardware components for execution.
If you’re really into tinkering with your 3D printer, you can even consider changing up its firmware. This can potentially improve the performance of your 3D printer. Here’s our guide on how to change the firmware of your 3D printer, as well as the most popular firmware options.
What does the firmware do?
The firmware of the 3D printer is often described as the bridge between hardware and software. It is a program that can interpret commands from the G-Code and translate these commands into specific actions of the hardware components.
To demonstrate, the firmware can read a G-Code command like “M109 S180” and it will send an instruction to the heating block to increase its temperature up to 180 C. Similarly, a G-Code command like “G1 X20 Y50” will prompt the firmware to send instructions to the stepper motors that control the movement of the print head so that it will reach the position described by X=20 and Y=50.
Underneath all these seemingly simple instructions are thousands of calculations and logic operations that the firmware does. This determines just how precisely and accurately the components of a 3D printer function. In some cases, firmware can have unique features that open up different options for 3D printing.
Why should you change a 3D printer’s firmware?
Although changing a 3D printer’s firmware does not take a lot of work, it can be quite a daunting task if you’re doing it for the first time. There will almost certainly be some troubleshooting involved, as well as a new learning curve that you will have to overcome.
Is a new firmware worth all the extra work? Here are a few good reasons for making a firmware change:
Hardware changes
The number one reason that people change firmware is because of compatibility issues. This can come up if you’re installing a new control board in your 3D printer. Some control boards may have a limited list of compatible firmware. In some cases, your new control board may only work with a proprietary firmware.
Before getting a new control board, make sure to do your due diligence and check for any compatibility issues. If you’re unsure about any compatibility issues, then it would not hurt to ask the manufacturer.
Faster performance
Each firmware is uniquely coded and gets periodic upgrades. This can mean significant differences in performance across different firmware. In many cases, this can mean better performance for your 3D printer through faster calculations and more precise movement. Tweaking with firmware is one of the many ways that professionals can make their 3D printers just a little bit faster or more accurate.
Unique features
3D printing firmware might also have differences that are more than subtle. One firmware may offer better compatibility with multiple extruders, while another may support the printing speeds of Delta or CoreXY 3D printers. These are highly specialized features that you may find only on a specific handful of firmware options.
Most popular 3D printing firmware
There are probably more than a dozen different firmware options out there for 3D printers, but we will just narrow down the list to the five most popular and widely used.
1. Marlin
To this day, Marlin remains the most widely used firmware in 3D printing. Created in 2011, Marlin has since been adopted and improved by a huge community via GitHub. With this level of support, GitHub is known as one of the more reliable firmware options – should it have any bugs, you can count on the community to have them fixed quickly.
This open-source nature is also one of the reasons why Marlin is known as a highly versatile firmware.
It can be used on both 8-bit boards and 32-bit boards and is compatible with a wide range of 3D printers and control boards. Users who are building their own 3D printers from separate components often go to Marlin as their firmware of choice.
Marlin is compatible with practically any type of 3D printer hardware. It works with Cartesian, Delta, and CoreXY printers, multi-extrusion printers, auto bed leveling, filament run-out sensors, heater power control, and up to 30 languages. Marlin is so versatile that it is often also used in CNC machines.
2. Repetier
Repetier is as much a mainstay in the 3D printing community as Marlin. It works with a wide range of 8-bit boards and, more specifically, control boards that use Arduino. It is mainly this lack of compatibility issues that has made Repetier popular for a very long time.
In terms of reliability and consistency in performance, Repetier is an excellent firmware choice. It works exceptionally well with the Repetier Host all-in-one software, so you might want to consider combining the two in your 3D printing setup.
Repetier supports various performance and quality-of-life issues. These include high-speed printing, compatibility with LCD monitors, and the ability to print files directly off SD cards. With its long history and very active community of users, documentation and guides on Repetier are easily available and incredibly detailed.
3. Prusa
Prusa is one of the top brands in the market for 3D printers, so it’s no surprise that their proprietary firmware is also excellent. The Prusa firmware is a modified version of Marlin that is programmed specifically to work with the Einsy Rambo control boards of Prusa 3D printers. This is probably the biggest drawback of this firmware – you can’t really use it unless you own a 3D printer from Prusa.
The big advantage of developing firmware specifically for a small selection of 3D printers is that it can be optimized to work extremely well with the hardware. The Prusa firmware supports all the best features that Prusa printers have been known for.
These features include multiple extruders, multi-material printing, mesh bed leveling, and temperature oversampling. Despite being proprietary, the Prusa firmware is still open-source and has benefitted from user customization and improvement.
4. Klipper
Klipper takes a different approach to processing G-Code commands. Instead of the control board having to do all operations, some of the execution steps are off-loaded to a separate microcontroller in addition to a general-purpose computer such as a Raspberry Pi. The result is that Klipper can do calculations much faster, making it an ideal firmware for high-speed 3D printers.
With a more sophisticated processing sequence, Klipper is capable of executing more steps per second. This can result in significantly improved print quality and detail accuracy. One of its more intriguing features is its ability to cancel out errant movements of the print head using an attached accelerometer. This can help avoid common artifacts such as ringing or misaligned layers.
The biggest drawback of Klipper is that it’s a lot more complex to set up, especially compared to more mainstream options like Marlin.
5. SmoothieWare
SmoothieWare is firmware that was written specifically for the Smoothieboard controller, but its compatibility range has expanded a bit since then. This firmware for 32-bit boars boasts of easy configuration and versatility not just for 3D printers, but also laser engravers and CNC machines.
The focus of this firmware is performance and freedom of configuration. It allows for jerk-free motion even when running at higher speeds, making it ideal for CoreXY and Delta 3D printers. Setting up Smoothieware is easy if you will be running it on a Smoothieboard controller, mostly because most of the documentation is based on the original hardware.
If you’re using a Smoothieboard, then installing Smoothieware is really a no-brainer. Unfortunately, the range of compatible boards is still very limited. If you’re lucky enough to have a compatible board, the Smoothieboard is among one of the best firmware in terms of performance and ease of use.
How to check your 3D printer’s firmware
If you’re still just beginning with 3D printing, you might now even know exactly which firmware your 3D printer is using. There are several ways that you can check depending on your 3D printer.
- If your 3D printer comes with a firmware by default, then it is likely documented in the printer’s manual. You can also try checking if the printer displays the firmware name and version on its display or user interface.
- Conversely, you can use access the firmware of your control board using a console and send the M115 command. This will return the firmware information including its name and version. In some cases, this will also provide a link to where the source code of the firmware can be downloaded.
Knowing your printer’s firmware has several advantages. The first is that you can check if there are more recent versions of your firmware. You can also try to check online for community support should you run into problems.
Lastly, it is crucial information in deciding whether a change in firmware is in order.
How to install new firmware in your 3D printer
If you have finally decided on installing new firmware in your 3D printer, there are a few things that you will need to download or look up online first. These can be done on any standard computer. The one you use regularly with your 3D printer should work perfectly fine.
Download the firmware and lookup printer settings
The first step would be to download the firmware of your choice. The default option would be to download the latest version, although you may want to look at the developer notes to see if there are any bugs that need to be addressed. In such a case, it would be better to stick with the latest stable release.
Each firmware should have a general profile for the type of 3D printer you are using. Now would be a good time to look this up and write down the most important parameters. At a minimum, this includes the steps of all the stepper motors, as well as their maximum feed rates and travel distance values.
This will eliminate much guesswork in setting up the new firmware.
Some firmware options, such as Marlin, come with an “examples” folder that has configuration files for the most popular 3D printers. You can try exploring for those or read up on the documentation of your firmware.
Download Arduino IDE
The Arduino Integrated Development Environment (IDE) will allow you to view the code for the firmware, edit it, compile, and upload it to the 3D printer. It can be downloaded here.
First off, connect your computer to the 3D printer using a USB cable and open your firmware of choice using Arduino IDE. At this point, you can edit the firmware code according to the recommended parameters for your printer.
Go to the “Tools” section of Arduino IDE and look for the control board of your 3D printer in the drop-down list. You can then click the “Verify” button at the top left of the window which will start compiling the code. Hopefully, the code will compile without errors.
With the firmware compiled, you can now upload it to your 3D printer using the “Upload” button, also located in the upper left section. If you’re changing to a completely new firmware, many of your printer settings will likely have been reset to default values. To restore these settings based on your preferred configuration, you can run the “Initialize EEPROM” tool in the interface of your 3D printer.
Final thoughts
The idea of changing the firmware of your 3D printer may seem daunting, and that’s for good reason – this is not something that you should do on a whim. Using new firmware could mean having to reevaluate the settings of your 3D printer, with due consideration of how it works with different filaments.
We have outlined some of the acceptable reasons for changing a 3D printer’s firmware. You can do it to improve the printer’s performance or just to avoid compatibility issues. The act of changing the firmware actually isn’t very hard. The real challenge is in adjusting and learning how to use the new firmware.
Warning; 3D printers should never be left unattended. They can pose a firesafety hazard.

Firmware installation procedure:
menu Configuration -> EEPROM configuration
4) Select "Export EEPROM data", save the *.mepr file in a convenient location
5) Download the new firmware from
6) To upload the firmware to the 3D printer, rename the firmware file to firmware.
bin
7) Copy the firmware.bin file to the internal memory of the 3D printer (defined as a disk in Windows)
8) Restart the 3D printer with the button below the monitor. This will automatically overwrite the new firmware in the printer's memory
9) After the printer becomes active, turn it off. If this is not done, the firmware may not work correctly the first time
10) Turn on the 3D printer again, run the program "Repetier-Host", in the menu Configuration -> EEPROM configuration select "Import EEPROM data", import the previously saved settings in a file with *.mepr extension
11) 3D printer ready to go
What is the Clipper and should I use it?
Klipper is a very powerful firmware add-on for most 3D printers.
Before jumping into Klipper, it's first important to understand the computing technology commonly used in desktop 3D printers. The most common configurations involve a microcontroller board such as an Arduino, Duet, or other model.
These devices are directly connected to stepper motors that drive the movement system, heaters and other elements of the system.
These microcontrollers use firmware, which is simply software that runs on these embedded microcontrollers. Of several widely used standard firmware versions, perhaps the most popular today is Marlin.
The problem is that microcontroller boards usually do not have enough power for what is required of them. They don't have enough power because they are the least expensive boards you can find for a given configuration. This allows the manufacturer to keep the price of the machine low while still operating at an acceptable level of performance.
However, there are many who want to develop their equipment further. In particular, two aspects are desirable:
Faster print speed
Best print quality
Often they are related: if you type too fast, the quality suffers. If you type slower, the print will be better, but at the expense of time.
Klipper can solve these problems by introducing new possibilities. Their project explains:
“Klipper is a firmware for a 3D printer. It combines the power of a mainframe computer with one or more microcontrollers.”
They add a much more powerful general purpose computer that will sit on top of microcontrollers and provide more computing power. This capacity can be used both to increase speed and to maintain or even improve print quality.
Klipper's main feature is that it takes the burden of stepper motor calculation that would otherwise fall on a low-capacity microcontroller board. Klipper uses all its power to calculate the printer's steps and simply passes the received instructions to the microcontroller for execution.
This calculation model allows for much faster stepper motor movements because the microcontroller does not get bogged down in the calculations. And that means you can 3D print faster. Clipper says that even old 8-bit microcontroller boards can be rated at up to 175k steps per second! For modern boards, they claim they reach 500k steps per second.
But there is another problem: when you turn the tool so fast, you have to overcome a lot of momentum. Clipper does the same. They explain:
“Each step event is scheduled to within 25 microseconds or faster. The software does not use kinematic estimates (such as Bresenham's algorithm) - instead, it calculates the exact step time based on the physics of acceleration and the physics of the machine's kinematics. A more precise stepping motion ensures a quieter and more stable operation of the printer.”
Klipper uses processing capabilities for other features, one of which is called "Smooth Pressure Advance". This is an extended calculation to account for fluid pressure flow at the hot end of an extruder.
As you might have guessed, simply starting and stopping the extruder does not mean stopping and starting extrusion exactly. As the extruder pushes the filament into the hot end, the pressure gradually builds up until it reaches a critical point, and then the flow begins to flow out of the nozzle.
Similarly, when the extruder motor stops the pressure at the hot end, and therefore the nozzle, does not stop immediately.
Smooth Pressure Advance performs advanced calculations to control these effects. In other words, extrusions should start and stop exactly when they should. This should result in fewer gaps and smudges on the prints, as well as greatly reduce the stretching of the mucus from the nozzle.
Another interesting feature is "Input Shaping" which eliminates ringing. Ringing occurs in the form of repetitive waves at the corners of objects. The pattern reflects the vibrations that occur when the direction of the print head changes abruptly.
Sound degrades surface quality, but can be reduced or eliminated with Input Shaping, which again uses processing power to calculate toolpath instructions, avoiding ringing effects.
Klipper offers many other features that you can see on their Features page.
Klipper is available for free via GitHub and can be installed using OctoPrint.
