Kraken Motors from Devil Design LDO-42STH60-3004AH (S37 and S55) Extreme Stepper MotorRound shafts offer added support at the end of the shaft, making them great for high torque applications, frequent direction changes, and setups where extra stability counts. Recommended for High Performance Builds: If youre working on a high torque or high precision setup, a round shaft motor can help maintain accuracy under more demanding conditions. Maintenance Tip: Locking compound on grub screws will help ensure these motors stay securely

Round shafts offer added support at the end of the shaft, making them great for high-torque applications, frequent direction changes, and setups where extra stability counts.

Recommended for High-Performance Builds: If you’re working on a high-torque or high-precision setup, a round shaft motor can help maintain accuracy under more demanding conditions.

Maintenance Tip: Locking compound on grub screws will help ensure these motors stay securely fastened, even with repeated directional changes.
Both motor types are excellent choices for 3D printers, depending on your specific project needs. The D-cut shaft is user-friendly and reliable in lighter applications, while the round shaft offers robust support for high-torque demands.

Key Features:

  • High Torque and Speed: Conquer challenging tasks with the Kraken Motors' impressive power output.
  • Precise Control: Achieve pinpoint accuracy in your movements for intricate and detailed work.
  • Smooth Operation: Minimize vibrations and ensure consistent performance for optimal results.
  • Durable Construction: Built to withstand the rigors of demanding applications, ensuring long-lasting reliability. Class H insulated (180C)
  • Temperature Monitoring: This motor has an internal ATC Semitec 104GT-2 thermistor to keep a close eye on those motor temperatures.
  • Versatile Applications: Perfect for robotics, CNC machines, 3D printers, and other projects requiring high-performance motion control.

The high temp Kraken is finally here. Designed by Omranello from Devil Designs, these motors were made for applications where high torque is needed. This motor has an internal ATC Semitec 104GT-2 thermistor to keep a close eye on those motor temperatures. Included is a 1 meter long wire for the motor and thermistor, the motor wires are terminated with a 4 pin JST-XH connector.

Pulleys are not included!

Understanding D-Cut vs. Round Shaft Stepper Motors

When selecting between D-cut and round shaft stepper motors, both have unique advantages, making each well-suited to specific 3D printer setups.

D-Cut Shaft Motors – Popular and Easy to Use

Alignment-Friendly: The D-cut makes it easy to align set screws, providing a simple and user-friendly setup process.
Best For Light and Moderate Use: These motors excel in lighter applications where high torque and rapid directional changes aren’t a primary need. Perfect for builds that require steady, low-torque motion.
Maintenance Tip: We recommend using a locking compound (like Vibratite 125) on grub screws for added reliability, especially when used in lower-vibration settings.
Round Shaft Motors – Optimal for Stability and Heavy Use

Quality product you
Model: 18 SqFt(1.7 SqM), Model: 18 SqFt(1.7 SqM)
Summary: Great quality product, priced right. Cuts and installs easy-follow the instructions people!! PRO TIP-you don’t need to cover every square inch. OVERKILL!! Think about it-when a bell rings you could put your fingers on the edge and silence it right? Same rules apply here. A strip or square will isolate the vibration and notice when placed correctly— knock on the surface and see what vibrates or what part makes the loudest drowning and that’s a good clue of where you should put a piece of this…unless you’re trying to use it for temperature insulation no need to go ape on it. If you look at the bottom of a stainless steel sink, it’s got a stripe or a small sticker of insulation that keeps it from rattling. You can do that here. What’s important to note is the instruction specifically say use a roller to roll the ribs out until it’s smooth that way you’ve got maximum adhesion. I see a lot of pictures and videos from people that finished their install and didn’t follow this simple instruction. It makes sure that it’s stuck down before you put all your paneling and carpet back in and it’s a small step with a cheap wooden roller it’s easy. I’ll say the installation with this product is a breeze. You can use sharp scissors or a blade. It does get gummy after a while, and you may need to clean off your blade or your scissors, but it cuts very well and the ribs make it easy to size in space the thickness is fantastic and the backing paper comes off quite easily. I’ve done lots of installations with Graphics emblems you name it and this product is very easy to use and represents good value.

Good stuff !
Model: 36 SqFt(3.4 SqM), Model: 36 SqFt(3.4 SqM)
This is an excellent product. Easily moldable, cuttable with good scissors or razor knife, very sticky, works great. This pack was enough to do all 4 doors on a crew max truck, and I went wild on the fronts. I used 9 peices on each rear door which was just enough, and the rest on the fronts. I doubled up layers and even used some on the back of the door panels. If you follow the instructions and dont go wild you might even have extra left over. It works just like you would imagine. Without doing the entire cab there will still be road noise but this helped noise, better audio, no buzzing door panels, terrific improvement. It is kind of heavy, so extra weight is added to truck, but that really isnt a bad thing. It is noticable but in a good way. Get it. Use it.

Great product - Add foam product for complete solution
Model: 36 SqFt(3.4 SqM)
Used in two cars with speaker upgrades. Easy to install but get the roller for assured adhesion.removes "tinnyness" from large metal resonators. Use with foam absorptive material for a complete system.
