Motors are certainly awesome components, used in all shapes and sizes from tiny buzzer motors in smart phones all the way through to the starter motors in large vehicles. However, if you’ve ever taken a motor apart, you’ll know that motors are actually quite simple, and the true beauty really lies in the Motor Drivers, and how they wrangle electrons in just the right way for torque, speed and control. This is why we often get more excited about getting in new Stepper Drivers, rather than the actual Stepper Motors, as the drivers are really the stars of the show, allowing us all to use the motors with far more precision, power and finesse than ever before – and sometimes even offering some cool features for extra functionality and performance too.

These BTT TMC2160 Stepper Motor Drivers are excellent examples of drivers that really let Makers get the most out of their Stepper Motors, offering UltraQuiet operations with SpreadCycle and StealthChop2, the more recent StallGuard2 feature that allows for sensorless feedback and longer motor lifespans, as well as some other features that you should already know about if you’re a fan of Trinamic’s world-famous TMC Drivers. All of these awesome features are packed into a relatively discrete and strong heatsink enclosure, with convenient screw terminals and tiny toggle switches for a simple connection and operation style.


The Key Features of TMC2160 Stepper Motor Drivers:

Although these stepper drivers really do look good, being quite beefy but elegant at the same time, what we’re really interested in as Makers is what’s under the hood, what kinds of cool benefits we can enjoy from the classic Trinamic features, and how these can benefit us in 3D Printing and other CNC applications. So, let’s dive into our three favourite features:

  • StallGuard2: StallGuard is a clever Trinamic-patented tech’ that is able to ascertain real-time sensorless feedback from the motors, which is typically caused by EMF and excess current. This allows you to technically utilise the motors as sensors, eliminating the need for end switches, as StallGuard2 can simply detect when the motors stall after reaching the end of their travel path. This is also more precise than simple end switches, as instead of a Yes/No kind of feedback, they get variable feedback from the motors depending on the speed, torque and other forces involved in the process. However, it must be noted that StallGuard2 can’t be used in conjunction with StealthChop (only StallGuard4 is capable of this), but it CAN be used on conjunction with SpreadCycle, which performs quite similarly to StealthChop, but doesn’t have quite offer the same level of smoothness throughout the entire torque range.

  • Microstep Table: As a way to expand even further on the very impressive traits of Trinamic stepper drivers, TMC2160 drivers also feature what Trinamic have called a Programmable Adaptive Microstep Table, which is an extremely clever system that attempts to do three things, which include distributing the Microsteps evenly regardless of how many Microsteps need to be done, provide a constant velocity even at slow speeds, and ensure constant torque independent of motor position (this last factor is quite complicated, and the solution was in fact quite ingenious). As such, you can now take your stepping to a whole new level with this handy How The Microstep Table Works guide, which should help you understand precisely what it does, and how you can tune it to cater to your specific motors.

  • StealthChop2: If you already know what the original StealthChop is, and the awesome benefits that it offers, then you will hopefully be just as excited as we are with the new StealthChop2, which is similar to original, but integrates a current pre-regulator to avoid overcompensation of step prediction, while allowing for more torque during acceleration phases. And while this may sound complicated at first, what it translates to is fewer missed steps or overshot steps, as well as a higher level of power even when motors are caught in an odd rotor position. This means more reliability and more predictability for your motors, and of course the awesome near-silent operations that both StealthChop and SpreadCycle are well-known for.

As one of the rising stars in the world of 3D Printer Component Research and Development, BigTreeTech have certainly hit the ground running, entering the market in 2015 and spending their early stages primarily learning, researching, testing and developing, before producing some truly impressive results. From simple but effective upgrades to standard parts, all the way through to completely custom parts that no other brand offered at the time, BigTreeTech now have an incredibly diverse range, with almost no area of 3D Printing being left out.

Some of BigTreeTech’s most notable additions to the world of 3D Printing include the SKR Motherboard Range for numerous different 3D Printer models, the awesome TFT Touch Display Range with fancy features like dual-mode operation, as well as their very impressive Stepper Driver Range that cater to all tastes and preferences under the sun. And of course, to top it all off, BigTreeTech also have a sister company named BIQU, and we must admit that they have been producing some pretty impressive (and low price) 3D Printers, with the BIQU B1 possibly becoming a new rival to the Ender 3.

Of course, it’s easy to see that BigTreeTech are modern masters of 3D Printing R&D, and while we do still have a lot of different parts that we want to test out from them, so far we’ve been extremely happy with what they’re capable of producing – all while fitting into same kind of hobbyist budget that they used to operate on as Makers and Tinkerers themselves.
