BIGTREETECH EBB42 CAN is a nozzle adapter board specially designed for a 42 stepper motor extruder (NEMA-17), which is launched by the 3D printing team Shenzhen Big Tree Technology Co., Ltd. It can communicate via USB or CAN, which will greatly simplify the wirings.

Main Features:

  • With BOOT and RESET buttons reserved, users can update the firmware via DFU mode by USB.
  • Added protection circuit on the thermistor avoids burning the main control chip caused by leakage current from the heating rod.
  • Users can select the thermistor's pull-up resistor values through a jumper wire, so as to support PT1000 (2.2K pull-up resistors), which makes it convenient for DIY.
  • Connect the USB with a jumper cap to get it powered on, which effectively isolates the main control board DC-DC from USB 5V.
  • Reserved I2C interface allows for filament broke and clogged detection, and supports other DIY functions.
  • Added anti-flyback diodes on the heating rod and fans' ports effectively protect the MOS tube from being burned due to reverse voltage.
  • Anti-reverse connection protection on the power interface prevents users from burning the motherboard when mistakenly connecting the reverse power line during DIY.
  • Onboard MAX31865 supports selecting 2-wire or 4-wire of PT100/ PT1000.
  • Supports communication via CAN or USB. The terminal resistor 120R of CAN can be selected through the jumper cap, and it reserves CAN expansion interfaces.
  • Equipped ESD protection chip on the USB port prevents the main control board from being broken down by the static electricity of the USB port.
  • The adaptor board is equipped with terminals, female reeds, double-way studs and screws, which are required for DIY, greatly meeting the DIY needs of customers.
