Isik’s Tech Ouroboros TMC4671 Stepper/Servo Controller

Isik’s Tech Ouroboros is a TMC4671 based FOC motor controller board designed for Klipper 3D printers, supporting stepper and BLDC motors. Ouroboros can control 2 motors, so you can control both X and Y motors of your printer.

FOC (field oriented control) can reduce resonances originating at the motor, improving print quality, even at very high speeds. FOC can also help make your printer quieter, and lower motor temperatures. Closed-loop helps avoid problems from missed steps. TMC4671 will compensate for skipped steps, avoiding crashes, layer shifts and print failures.

Ouroboros supports up to 15A peak current per motor, or 30A total, so even massive motors (by 3D printing standards) are supported. Ouroboros uses a high performance STM32H723 MCU to make sure you get the most out of these drivers.

Ouroboros features a CNC milled and anodised heatsink, and built-in brake resistors to make sure you have a very clean and compact electronics chamber.
