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

Fantastic for rough chewing
Color: Bule 0, Size: For Larege Dogs
Our big boy is rough with his toys and always seems to disintegrate his toys in seconds. I had seen this with hoping this will be the toy he doesn’t destroy. On day 2 now with the toy and he’s obsessed, even feel asleep with the toy in his mouth and still in one piece. Highly recommended for tough chewers.

Good but not for my dog
Color: A Red, Size: For Larege Dogs
Dog loves it but already falling apart. Can't seem to find a truly safe dog toy that won't come apart with my aggressive chewer. Had to toss it before pieces got ingested. But great toy in the begining. Just not safe for pit/staff type dog that destroy and chew.

Put your aggressive Chewer dog to the test!
Color: A Red, Size: For Larege Dogs
A very tough toy to stand up to my aggressive chewer lab! It's a great value! The squeak is not annoying, and she's got to clamp down hard on it. It's a nice throw toy! It bounces once or twice but it still brings out the pup in our Dog! Not too small a nice size for a Lab or retriever

A Hardy Toy for Chewers
Color: Bule Octopus, Size: For Larege Dogs, Color: Bule Octopus, Size: For Larege Dogs
I must say I was very surprised with the durability of this toy. We've had it for 3 days and not one puncture hole. My rescue is a destroy chewer that doesn't care for Hardy chew toys unless it squeaks. While the squeaker isn't the best, he still loves it. We put peanut butter in the grooves for him and he goes to town. Will purchase again should he ever destroys it, worth the price!

Durable toy for a great price! Will buy again.
Color: A Red, Size: For Larege Dogs, Color: A Red, Size: For Larege Dogs
Great toy, heavy, good size, and durable for active chewers. My two dogs like to play tug a war a lot and this toy has held up fantastically! Afterwards they tend to chew toys to pieces but this one has stood the test of time so far. Great buy!
