BIGTREETECH 1 Product Introduction BIGTREETECH EBB36 CAN V1.1 is a nozzle adapter board made by the 3D printing team of Shenzhen BIQU Technology Co., Ltd. for a 36 stepper motor extruder. It can communicate via a USB or CAN, which greatly simplifies wiring.
13. Support CAN bus connection, which has long data transmission, strong anti- noise ability, strong real-time performance and high reliability. 1.2 Product Parameters 1. Product Size: 51.5 x 37mm, for further details please read: BIGTREETECH EBB36 CAN V1.1-SIZE.pdf 2. Installation Dimensions: Hole Spacing 43.85mm, M3 Screw Hole x 2 3.
BIGTREETECH 3 Introduction of Interface 3.1 USB Power Supply After the motherboard is powered on, the yellow-green LED1 lights will light up, indicating a normal power supply. The VUSB on the right side of the board is the power selection terminal. Only when using USB to supply power to the motherboard or need to supply power through USB, do you need to use the jumper cap to connect VUSB.
BIGTREETECH 3.2 100K NTC or PT1000 Settings 1. Version without 31865: No need to plug a jumper cap when using a 100K NTC thermistor, and TH0's pull-up resistor value is 4.7K. When using PT1000, you need to use the jumper cap to short the two pins, as shown below picture. At this time, TH0's pull-up resistor value is 2.2K...
BIGTREETECH 4 Klipper 4.1 Firmware Compilation 1. After connecting to the Raspberry Pi via SSH, type the below sentences at the command line: cd ~/klipper/ make menuconfig Compile the firmware with the following configuration (if the following options are not available, please update the Klipper source to the latest version).
BIGTREETECH 3. Enter make to compile the firmware. The 'klipper.bin' firmware that we need will be generated on the home/pi/klipper/out folder of the Raspberry Pi when completed. The firmware is on the left side of SSH software, users can download it directly to the computer.

Type and run commands...
BIGTREETECH hardware is powered on and wired correctly, then run the following command: ~/klippy-env/bin/python ~/klipper/scripts/canbus_query.py can0 If detected an uninitialized CAN device, the above command will report the device's canbus_uuid: Found canbus_uuid=0e0d81e4210c If Klipper operates well and is connected to the device, then it won't report the canbus_uuid, which is normal.
BIGTREETECH 3. Add the motherboard's configuration to the file "printer.cfg". [include sample-bigtreetech-ebb-canbus-v1.1.cfg] 4. Revise the ID number of the configuration files as the actual ID of the motherboard (USB serial or CANBus). 5. Configure the specific functions of the module as instructed below: https://www.klipper3d.org/Overview.html...
BIGTREETECH 6 FAQ Q: What's the maximum current for the heater cartridge and fan interface? A: The maximum output current of the heater cartridge interface: 5A. The maximum output current of the fan interface: 1A. The total current for the heater cartridge, driver and fan needs to be less than 6A.
