• Ouroboros FOC Motor Controller

    Print beautiful prints at very high speeds using our Ouroboros FOC servo motor controller, supporting stepper and BLDC servos.

    FOC lets your motors run cooler, quieter and generate less vibrations helping you print faster without compromising on print quality. Closed-loop control detects skipped steps and compensates, also improving your 3DP experience.

    Ouroboros is assembled in America by us.
