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 anodized heatsink made in America, and built-in brake resistors to make sure you have a very clean and compact electronics chamber.
Ouroboros finished closed beta testing, and we're getting ready for production. We will be assembling these in-house in America. We expect to start shipping these in mid to late August. This is a preorder at a discounted price.
Please note that the current product image is of a prototype board. Production boards don't have fan and thermistor connectors, and instead have a expansion connector.
