Kraken Motors from Devil Design LDO-42STH60-3004AH (S37 and S55) Extreme Stepper Motor

High-torque 3D printer builds like Voron 2.4 and Trident require stepper motors that maintain precision under rapid directional changes and heavy loads — without them, layer shifting and print artifacts become common. Kraken Motors from Devil Design address these challenges with robust round shaft options designed for demanding CoreXY and high-performance Cartesian setups.

These LDO-42STH60-3004AH stepper motors, designed by Omranello of Devil Designs, deliver 8.0 kg/cm holding torque and smooth operation for intricate motion control. Available in both 37mm D-cut and 55mm round shaft variants, they suit a range of 3D printer builds including Voron, Trident, and other high-torque CoreXY machines. The integrated ATC Semitec 104GT-2 thermistor enables real-time temperature monitoring, protecting your motor during extended prints. Motors come with 1 meter wiring terminated in 4-pin JST-XH connectors for easy integration.
