What is the Best Stepper Motor/Driver for Your 3D Printer? – 3D Printerly

If you’ve wondering just which stepper motor/driver is best for your 3D printer, you’re in the right place. It’s a quite overlooked part of a 3D printer and it deserves a bit more of an informed decision rather than just sticking with what your printer came with.

Many people have reported prints improving after installing a better stepper motor on their 3D printer so which one is best for your 3D printer?

For such an essential part of a 3D printer, I’ve wondered which stepper motor is the best so I created this post to find that out so read along for the answers.

For the people that came for a quick answer, the best stepper motor for your 3D printer is going to be the StepperOnline NEMA 17 Motor. It’s highly rated on Amazon and is the #1 listing for Electric Motor Mounts. Low noise, long lifetime, high performance and no loose steps!

Many have described it as a plug-and-play motor but it does require a bit of know-how, but shouldn’t take too long at all to install. Once you install this stepper motor, any slip problems you’ve had previously should be dealt with easily.

If you are looking for the best stepper motor driver, I’d go for the BIGTREETECH TMC2209 V1.2 Stepper Motor Driver from Amazon. It significantly reduces noise in 3D printers and produces much smoother movements overall.

Now let’s get into what makes a stepper motor so important.

What are the Key Functions of a Stepper Motor?

Under the hood of every 3D printer out there, you’ll find a stepper motor.

The proper definition of a stepper motor is a brushless DC electric motor that divides a full rotation into an equal number of steps. The position of the motor can be ordered to move and hold at certain steps and used at your desired torque and speed.

In simpler terms, stepper motor is what the motherboard uses to communicate to the motors of your 3D printer to make it move around the various axes. It gives the precision, speed and positioning of how things move so it’s a very vital component of a printer.

The reason stepper motors are used in 3D printers is because of their wide range of benefits such as low cost, high torque, simplicity, low maintenance while being highly reliable, and works in just about any environment.

Also on the technical side of things, they are very reliable because there are no contact brushes in the motor, meaning the life of the motor depends solely on the longevity of the bearing.

Stepper motors are also used in medical instruments, engraving machines, textile equipment, packaging machines, CNC machines, robotics and much more. 

What Makes a Stepper Motor Better Than Others?

Now it’s important to know that there are many different sizes, styles and characteristics that a stepper motor can give you.

The factors that are important to us are the ones that work best for a 3D printer specifically. Since we need to consider how much work the motor is going to be doing, we take a few things into account.

The main factors that make a stepper motor better than another are:

  • Torque rating
  • Size of motor
  • Step count

Torque Rating

Most stepper motors have a torque rating which roughly translates to how powerful the motor is. Usually, the bigger the size of the motor, the more torque rating you’ll have because they have a better ability to deliver power.

You do have smaller 3D printers such as the Prusa Mini which would require less torque than lets say, an Anycubic Predator Delta Kossel so do keep the size of your printer in mind.

Size of Motor

You have a wide range of sizes for stepper motors, but many can definitely be too strong for a simple 3D printer, which doesn’t require too much performance.

For 3D printers, we generally go for the NEMA 17 (face plate dimensions 1.7 by 1.7 inches) because they are large enough to get the job done. 

You would usually use larger NEMA motors in products that require industrial applications or CNC machines. Do keep in mind that NEMA simply describes the size of the motor and not it’s other characteristics. Also, two NEMA 17 motors could be very different and are not necessarily interchangeable.

Step Count

The step count is what gives us the precision that we need in terms of movement or positioning resolution.

We call it the number of steps per revolution and it can range anywhere from 4 to 400 steps with the common steps counts being 24, 48 and 200. 200 steps per revolution translates to 1.8 degrees per step

For you to get a high resolution, you will have to sacrifice speed and torque. Basically, a high step count motor will have lower RPMs than another motor of a lower step count of comparable size.

If you need higher step rates to turn the motors efficiently, it will require more power so the torque comes in lower and vice versa. So if you want great precision of movement, you will need high step counts therefore reducing the amount of torque you have.

Best Stepper Motors You Can Buy Now

NEMA-17 Stepper Motor

StepperOnline NEMA 17 Motor as recommended at the start of this post is a great choice for a stepper motor. Thousands of happy customers have used this stepper motor with great success with its high quality and flexible customization.

It comes neatly packaged and is a bipolar, 2A motor with a 4-lead and 1M cable/connector. The only downside here are the cables are non-detachable. Do note that the colors of the cables don’t necessarily mean they are a pair.

The way to determine wire pairs is to spin the shaft, then touch two wires together and spin it again. If the shaft was more difficult to spin, those two wires are a pair. Then the other two wires are a pair.

Once you do install this stepper motor, your performance should be second to none and smooth for years to come.

Usongshine NEMA 17 Motor is another choice that is well-liked between 3D printer users and is slightly smaller than the above choice. This high torque stepper motor is made of high quality steel and has great performance.

A few advantages of this stepper motor is its effective thermal conductivity and quality control for each stepper motor that’s sold. You get your stepper motor (38mm), 4pin cable and connector a strong/quiet device to assist you in your 3D printing journey.

The wiring is better set out, with the black and red wires being A+ & B+ then the green and blue wires being A- & B-.

Customer service is also at the forefront of their product so you have good peace of mind after your purchase.

Even at print speeds of 120mm/s+ this stepper driver will deliver amazing performance every time.

Best Stepper Motor Driver for 3D Printers (Upgrades)

Kingprint TMC2208 V3.0

There are many stepper motor drivers out there you can get for your 3D printer, but you’ll want to get one that works well for your particular machine.

The Kingprint TMC2208 V3.0 Stepper Damper with Heat Sink Driver (4 Pack) from Amazon is a great choice that many users have loved using. One user said he went from using standard drivers to these, and the difference in noise and control was astounding.

Previously, he had a very noisy 3D printer that also had jitters throughout the printing process, but now, the printing is silent and really smooth. They have a good large exposed heatsink area, so the installation is made a little easier.

The difference between these and classic 4988 steppers are huge. Another nice feature that has been added to this is the pin headers for UART access, so you don’t have to solder them on yourself.

One user mentioned how she didn’t realize 3D printing could be so silent, making a really dramatic difference in noise. If your 3D printer vibrates a lot, even to the point where your table vibrates like another user, you’ll want to get these installed as soon as possible.

After installing this, the loudest thing on people’s 3D printers are the fans.

BIGTREETECH TMC2209 V1.2 Stepper Motor Driver

BIGTREETECH is a very well-known 3D printer accessories company that produces really reliable and useful parts. If you are looking for some of the best stepper motor drivers, you’ll want to look into getting yourself the BIGTREETECH TMC2209 V1.2 Stepper Motor Driver from Amazon.

They have a 2.8A peak driver, made for SKR V1.4 Turbo, SKR V1.4, SKR Pro V1.2, SKR V1.3 Motherboard, and comes with 2 pieces.

  • The motor makes it very hard to lose steps; ultra-quiet mode
  • Has a large thermal pad area to reduce the temperature of the work
  • Prevents motor shake
  • Supports stall detection
  • Supports STEP / DIR and UART mode

The TMC2209 is an upgrade over the TMC2208 in that it has an increased current of 0.6A-0.8A, but also increases the function of stall detection. It has some cool technology within the part such as SpreadCycle4 TM, StealthChop2TM, MicroPlyer TM, StallGuard3TM & CoolStep.

These do things such as give more control, reduce noise, and provide a smoother operation.

One user said they paired these stepper motor drivers with the SKR 1.4 Turbo, along with a new screen and now their 3D printer is smooth and silent. You won’t regret making this great upgrade if you are facing issues of noise and large vibrations.

I saw, I plan, I collect a 3d printer from trash and sticks / Sudo Null IT News

I have long wanted to have a 3d printer. A year and a half - exactly, maybe even more. I even learned how to model a little in DesignSpark Mechanical and occasionally drew all sorts of useful and not very things in it, for example, I redid the buttons on my Logitech G27 steering wheel to make it easier to press with gloves: G27 Button Plates. The flight of fancy in the manufacture of all sorts of different things was limited only by the lack of a printer, because printing somewhere else is long, inconvenient and not too cheap. Only one thing stopped me - I needed money for my printer, and for some reason they are always chronically lacking. After much deliberation, I decided to assemble the printer myself, and, given the above circumstance, to make the most of any rubbish lying around at work. nine0210
Since before that I had only seen 3D printers from afar and had a very rough idea about them, I began preparations by studying the forums, while the best one I found from Russian speakers on this topic is the section on 3D printing on roboforum.ru (http://roboforum. ru/forum107/). Local elders recommend assembling the first Mendel90 printer from dibond (aluminum composite sheets), by this time I had already begun to assemble Prusa i3 from 12 mm plywood. Looking ahead, I’ll say that this is not the best choice, it was necessary either to order a ready-made aluminum frame, or to do all the same Mendel90, it is much more rigid, which will increase print speed and reduce noise and vibration.

The first step I tried to imagine what exactly I will collect. DS Mechanical was fine for a quick first sketch:

A sample shopping list originally looked like this:

The printed parts were not supposed to be used at all, the steppers were to be hung on metal corners, the vertical feed was on M8 construction studs, the frame and table were made of 12 mm plywood, the guides were 8 mm with SC8UU plain bearings, clamped into SK-8 brackets (all searched on eBay by name). I made a preliminary list of parts and started looking on ebay for what you can buy at auctions cheaper. While choosing where to buy cheaper - I drew a sheet of plywood:

Sawed by hand, no laser cutting, only electric jigsaw, only hardcore!

While I was processing pieces of wood, I was picking up an old scanner at work, a couple of matrix printers, a card embosser, I managed to get hold of one long 8 mm shaft, two short 10 mm, a steep aluminum rail along which a steel plate with holes rode on wheels. From there, I broke out the fastenings of the print head of the matrix, they had bronze plain bearings. As a result, already at the frame assembly stage, small changes were made to the project and the frame already differed from the first picture:

One of the 8 mm shafts still had to be ordered, the hope of finding suitable steppers in the printers did not materialize, NEMA 17 still comes across in the matrix, but with insufficient torque and a tightly mounted gear, which I could not remove. Since I ditched the 8mm x guides in favor of the embosser rail, I drastically reduced the number of SC8UU bearings needed, in the final version, three were enough. By the way, the bearings are shit, when I put them on the shaft - balls flew from one to the floor, they slide badly too, they have no lubrication at all from the factory. I ordered extended LM8LUU to replace, I'll see how they behave. In general, the people of the carriage and on rolling bearings collect, they say that it turns out much better. nine0003

The plywood frame is not too rigid, so I decided to use a Bowden extruder to increase the print accuracy. The lighter the head, the less the frame will swing during acceleration, the higher the print accuracy. I managed to find a small and light hot end, with a very successful fastening at the bottom with a copper plate, and not with a clamp at the top, like most:

frames. In general, it is better to immediately assemble a reinforced version of the frame, such as this one:

Separately, I want to mention the plywood hot table - never do that! I was tormented to put it evenly, 12 mm plywood easily bends when tightening the fastening of the heating element, on the third attempt I managed to achieve relief fluctuations on the printed surface within 1 mm over the entire area, but it was not easy. It’s better to take a ready-made aluminum one, on eBay in the region of $ 30, but how much nerves you will save is beyond words.

The second interesting point is that the parts from the children's iron constructor were very useful, while the printer itself cannot print yet - a lot can be assembled from it. Here, for example, the belt roller along the Y axis:

Another way to save money is the power supply. The savings, however, are so-so, the power supply for LED strips for 12 volts 30 amps on eBay costs not at all space $ 30. I decided to go my own way again and used a 500W power supply from an HP Proliant server, which delivers the same 30 amps on the 12 volt line, but at the same time it makes quite a noticeable noise. The power is enough, but I'd rather change it to something quieter.

I decided to use the cheapest electronics - RAMPS 1.4 + Mega R3, however, I took more powerful drivers - DRV8825. Radiators were included with them, they were of little use, they warmed up so that it hurt to hold your hand, I hung a 60 mm fan with a diameter of 0.2 A opposite, now they almost do not heat up even without radiators. By the way, I am very surprised that many people advise using microstepping 1/16, I even had skipped steps at 1/8, everything was fine at 1/4. The direct drive extruder works without microstepping at all, it is noisy, but there are no feed problems. Carefully insert drivers into RAMPS !!! Insert it upside down or with an offset - the arduina will rise beautifully and go to the trash, I have both chips burned out :(((

As a result, after a couple of months of finishing with a hacksaw, jigsaw, needle files, soldering and twisting, the printer looked like this:

I am printing a raft…

There were no problems with the mechanics right away, a box with a thickness of 1 layer 0.2 mm was printed immediately evenly and with the correct dimensions, except that the upper layers settled due to lack of cooling. True, I almost immediately replaced the roller from the designer with a normal bearing with a self-printed mount:

Did I manage to save money? Yes, probably 30 percent of the cost of the Chinese Prusa i3 kit with shipping. Everything works, I print with a layer of 0.2 with good quality, there is a slight wobble along the Z axis, I think it will be possible to remove it by changing the fastening of the studs, perhaps by switching to thinner studs.
