What is a stepper motor driver for a 3D printer?

A stepper motor driver is a component that you will find in every 3D printer. This includes the more affordable models right through to the high-end machines. To understand how it works, we need to look at the actual printing process.

First of all, your 3D models are turned into three-dimensional coordinates that are known as G code. The code also contains information for things such as the speed of the fan and temperatures.

This is fed to the 3D printer microcontroller which is essentially a basic computer within your machine. It reads the code and determines which stepper motors need to be moved in order to create your 3D models.

Each stepper motor has a driver that allows it to move independently.

In order to do this, pulses of electrical current are sent between the microcontroller and stepper motor driver in order for the stepper motors to move correctly.

Types of stepper motor drivers for 3D printers

There are different types of stepper motor drivers that are designed for 3D printers.

Here are the three main versions that you will come across.

L/R Stepper Motor Driver

This type of stepper motor driver carried out rotations at a low to medium speed and this can result in fairly limited ranges of power output. They can still offer a full rotation but they don’t usually offer control in regards to variable current levels.

Many people would class the L/R stepper motor drivers as low performance or at least low to medium performance.

Chopper Stepper Motor Driver – Micro-step

A chopper stepper motor driver is also known as a PWM (pulse width modulation) or micro step driver. It works on a solitary supply of high voltage and has output transistors that have come on and off automatically.

These types of stepper motor drivers are able to use a micro step mode. This means that it runs smoother and more efficiently as the current rate is regulated at all speeds. This provides a boost in performance however it comes with a higher price tag and the design is generally more complex.

They are also known to produce RFI (Radio Frequency Interference) and can sometimes overheat too.

Bi-level Stepper Motor Driver

The third type of stepper motor driver is the bi-level and this can use both high and low-level voltages.

It works by powering up to a high rate of current and when it reaches the level that you need, the high voltage is turned off. The low voltage is then used to maintain this level of supply when it is in use.

These stepper motor drivers are usually more efficient than others and they generally come at a fairly low cost as well.

Benefits of upgrading your stepper motor driver

Upgrading this relatively simple component on your 3D printer can produce several benefits.

Let’s have a quick look at why upgrading your stepper motor driver can be advantageous.

They can cut down on the noise your 3D printer produces

3D printers – whether they are fairly affordable models or pricier multi-color machines – usually make some noise. Some will be a bit quieter than others however upgrading your stepper motor driver can help reduce the decibels your printer produces.

Some stepper motor drivers have a silent design and they use technology to cut down on noise. With the right model you may find that your 3D printer operates a lot quieter than it did before.

You can get more reliable prints

As the stepper motor driver is what controls the stepper motors, an upgrade version can help you to get more reliable prints.

Buying the best stepper motor driver can help the motors move more precisely with better positional accuracy.This in turn will ensure that all parts of the 3D printing process benefit. You’ll be able to print off higher quality and better objects simply by upgrading a fairly easy component.

Your 3D printer can save on power

Another benefit of upgrading your stepper motor driver is that it can have an impact on power consumption.

Some stepper motor drivers are smart in that they will reduce the current when not in use. This cuts down on the overall power consumption that your 3D printer uses. The various safety features on some stepper motor drivers can also help prevent damage if there is a surge in power or if it overheats.

Things to consider when buying a stepper motor driver

Buying the wrong model or a stepper motor driver that isn’t ideal for what you need can actually have a negative impact on the way your printer performs. These are some things to keep in mind before you purchase one.

Torque

The torque is related to the size of the stepper motor and it is related to how big the motor is. In a simple sense, the more torque the more power. You will need to take this into consideration with what printer you have.

Some 3D printers won’t be able to handle higher torque and some won’t perform correctly with lower torque.

Accuracy

Most stepper motor drivers that are an upgrade on your stock one will probably help create more accurate prints anyway. That being said, you need to consider how much accuracy you need.

This can and often does impact on the price as well. The accuracy is usually determined by either small steps or a convoluted gear train.

Cost

There are a ton of stepper motor drivers out there and many manufacturers have been producing them for years. They aren’t the priciest things you can buy for a 3D printer but even for a small component, you need to factor in the cost to your budget.

Remember that the more a stepper motor driver costs don’t necessarily equate to how well it will perform. Many manufacturers will offer discounts and less price per component the more you buy at once.

Compatibility

Even though the majority of stepper motor drivers are compatible with most 3D printers, you will come across some that are designed for certain models. Make sure you read into the types and makes of 3D printers that the stepper motor driver you want to buy is compatible with before you make a purchase.

Best Stepper Motor Driver Brands

Stepper motor drivers for 3D printers are made by different companies and manufacturers. These are some of the top brands you will come across.
