With 3D Printing advancing at a blazing speed, it’s no surprise that Silent Stepper Drivers – although being an extremely popular feature upon introduced to scene, have become a common standard for a lot modern 3D Printers on the market. This is why we’re excited to bring silent stepper drivers to SA, so that 3D Makers can easily upgrade their 3D Printers to enjoy the near-silent operations with a range of awesome extra features that not only improve performance, but also efficiency and ease-of-use as well.

These TMC5161 Driver Boards from BigTreeTech are a small step up from the powerful TMC5160 driver, and offers not only slightly more power output, but also a new feature called Velocity Mode, amongst other great features that are iconic to the TMC brand. These drivers, like the TMC5160 Drivers, are most commonly used in conjunction with motherboards that utilise the classic Pololu StepStick based drivers, and bring a range of cool features along with good power, to provide an effective, efficient and surprisingly convenient end-user experience.


The Key Features of TMC5161 Stepper Motor Drivers:

If you’re already acquainted with the TMC5160 drivers from BigTreeTech, then you will already know precisely what this driver is capable of, focusing primarily on high power driving capabilities, while keeping some of the very best features from the TMC21xx and TMC22xx range of drivers. However, on top that, the TMC5161 is capable of slightly higher RMS power output, and also offers the very cool flexible ramp generator from the TMC5160, which we’ve definitely included in the following list of key features of the TMC5161:

  • 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.
  • 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.

  • SixPoint Ramp Generator: With most stepper drivers, you typically have to define their settings before even letting them loose, and if you want to change which motion profile they follow, you need to turn everything off and redefine them again. Of course, there are some stepper drivers that allow for configuration over UART and even WiFi, in such cases, you still have to stop printing – or at least stop the current action – to get the best motion profile for whatever part you’re busy printing. However, with the fantastic new SixPoint Ramp Generator that has been built into this driver board, you can enjoy all of the best aspects of all of the best features, as it can generate a custom motion profile for each action, with up to six different motion profiles spliced in together, to give you the absolute best from every TMC feature. Of course, just this explanation can’t do it justice, and if you’re eager to really dig in deep into how this works, we invite you to check out page 77 in the TMC5161 datasheet, and simply enjoy the amazing way that Trinamic have utilised and optimised all of their best features for a truly amazing result.

Please Note: Some motherboards may not yet support these drivers, so please be sure to do careful research on whether these will work for you or not before rushing in.

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.
