Bigtreetech MMB CAN V1.0 ERCF Control Board

The Bigtreetech MMB CAN V1.0 is a control board for multi-material 3D printing systems, e.g. the ERCF. It simplifies wiring by communicating via USB or CAN.

Feature Highlights
  • The board has BOOT and RESET buttons, allowing users to update
    firmware in DFU mode via USB.
  • I2C interface reserved for filament run out/clogging detection, or other DIY
    functions.
  • The power interface has reverse polarity protection to prevent the board
    from being damaged if power cables are connected incorrectly during DIY.
  • Supports CAN or USB communication, with selectable 120R terminal
    resistance for CAN and reserved CAN expansion interface.
  • USB port has ESD protection to prevent controller damage from
    electrostatic discharge.
  • Uses XT30 interface for CAN communication and board power supply,
    simplifying wiring.
  • Stepper motor driver supports high and low voltage selection for DIY use.
Why MMB CAN?
  • 32-bit, 64 MHz
  • 2+2 EZ Driver Sockets (requires EZ driver modules!)
  • 1+10 Endstop Ports
  • CAN bus
  • High-Voltage Driver Sockets (up to 60V)
High Performance You Can Rely On

Harness the power of the 32-bit, 64 MHz ARM Cortex-M0+ series MCU, the STM32G0B1CBT6, for precise control, ensuring exceptional print quality and reliability in your ERCF project.

Redundancy Meets Flexibility

The redundant design of the drivers and endstops provides backup interfaces and supports the DIY AMS project, increasing reliability and flexibility.

Simplified Wiring with CAN

Enjoy reliable communication, simplified wiring, and robust, stable data transmission for a smooth and efficient printing experience.

*The CAN bus interface is only functional when running the Klipper firmware.
