## Description

Product parameters1. Appearance size: 51.5mm*37mm2. Installation size: hole spacing 43.85mm, M3 screw hole*23. Microprocessor: ARM Cortex-M0 STM32G0B1CBT64. Input voltage: DC12V-DC24V 6A5. Logic voltage: DC 3.3V6. Heating interface: heating rod (E0), maximum output current: 5A7. Onboard sensor: ADXL3458. Fan interface: two CNC fans (FAN0, FAN1)9. Maximum output current of fan interface: 1A, peak value 1.5A10. Expansion interface: EndStop, I2C, Probe, RGB, PT100/PT1000, USB interface, CAN interface11. Motor drive: onboard TMC220912. Drive working mode: UART13. Stepper motor interface: EM14. Temperature sensor interface: 1 channel 100K NTC or PT1000 (TH0), 1 channel PT100/PT1000 optional15. USB communication interface: USB-Type-C16.DC 5V output maximum current: 1APrecautions1. When the PT1000 is not used for the TH0 interface, the jumper cap cannot be inserted on it, otherwise the 100K NTC cannot be used normally2. When using CAN communication, you need to see if it is used as a terminal. If it is a terminal, you must plug the jumper cap at the 120R position;3. When DIY crimping, you need to pay attention to the line sequence, and do DIY according to the Pin diagram to avoid the power line being reversed or connected to the CAN signal, which will cause the module to burn;4. When programming the program through the USB port, if there is no external power supply, you need to short the VUSB jumper cap to provide the module with working voltage;5. The load current of the heating rod and the fan interface should not be greater than the maximum withstand current to prevent the MOS tube from being burned out.

Review: BE VARY CAREFUL WIRING THE CAN BUS CONNECTOR!! The wiring diagram is very vague and misleading. Find a YouTube video to show you how to do it properly. As you will hear from many of the videos, it is extremely easy to misinterpret the CAN bus connector wiring and fry your board. This is a know issue to BigTree, and while they seem perfectly capable of rushing new hardware to the market to sell you, they are EXTREMELY lacking in documentation, addressing known issues, and customer support for it!.....For the record, I wired my correctly, but only because of the warnings and work of others unassociated with BigTreeTech! In my opinion, this is a company that is much more interested in selling you something than it is in supporting what you've bought! They are happy to leave that part to the community and consumers to figure out for them!!
Review: First off, I'm running this on an Anycubic Vyper conversion with a Stealthburner and a CW2 extruder. I've rewired my entire printer to accommodate CAN, and I'm running this in addition to an SKR Mini V3 3.0 a RasPi 4 8 GB, and a Waveshare RP485 Can Hat. I've purchased two of these boards, which we'll talk about shortly. The EBB36 board comes with everything you need to get set up, including two Molex Microfit 3.0 connectors and pins, a few JST connectors and pins, and some jumpers for initialization and termination. Like most of these DIY boards, you'll need to crimp your own connectors to get things running. But, if you're adding CAN to your printer, you're probably already familiar with how to do this. Flashing Klipper was easy, you just pop on a jumper and plug into your RasPi. I used Canboot, and there is plenty of info on how to do the same on the internet/Reddit. Software and support is outstanding via the BIGTREETECH github pages. You do, however, have to be careful with the polarity of your components. I accidentally reversed the polarity on my part cooling fan, and ended up frying the mosfets on the first one of these I bought. In a manner of seconds, I saw the magic smoke and realized my mistake. But things were already cooked. So, make sure you have the pinout for the board in front of you, and you double-check all your connections before powering the board on. Also, if you use ferrules on your heater wires, it may be helpful to swap the heater connection block around, so the terminal entry points face the USB connector. Those connectors have never been reliable for me, so I removed the block altogether and soldered my heater wires directly to the board. On the plus side, I will say I really like the fact that the EBB36 comes with a 120 ohm resistor built in, as it eliminates the need for additional resistors on the CanBus controller. I also like the fact that this board is built to fit around a Nema 14 stepper motor. It makes the whole Stealthburner setup look very clean. That said, there is one more pain point that deserves your consideration if you're going to buy the EBB36: that is the abundance of communication errors. Even after checking all my wiring and software settings and replacing my CAN hat, I will still occasionally get BLTouch communication errors when homing. Trying to chase this issue has been absolutely maddening. Though it's pretty sporadic. I've tried changing settings in the mcu.py file, adjusting jumpers, and resetting baud and TX rates, but nothing seems to help. Even now, I still haven't figured out why these errors are occurring. Many of the forums seem to think this is a common issue with this tool head setup, though I don't have enough experience to validate that claim. If I do get to the bottom of it, I'll amend this review to help those who might have the same problem. Overall, the EBB36 is a cheap way to get CAN working on your 3D printer. Just understand that getting it set up correctly might require a significant amount of time and troubleshooting. But if you're anything like me, you got into the 3D printing hobby because you enjoy that stuff anyway.

## Features

- 💖Smart Upgrade: Onboard MAX31865, support 2-wire/4-wire PT100/PT1000 selection, support CAN or USB communication, among which CAN terminal resistance 120R can be selected by jumper cap, and reserved CAN expansion interface, reserved RGB interface , to meet the lighting needs
- 💖Easy to Use: It is a 36-step (42-step) motor extruder nozzle adapter board, which can communicate through USB or CAN, which greatly simplifies wiring. BOOT and RESET buttons are reserved on the motherboard, users can enter DFU mode through USB to update the firmware
- 💖Superior Security: The EBB series has been optimized in multiple dimensions in terms of security. USB power-on is selected by jumper cap, which effectively isolates the DC-DC and USB 5V of the main board, and increases the protection circuit of the thermistor part to avoid the burning of the main control chip due to the leakage of the heating rod. The USB port adds an ESD protection chip to prevent the main control from being damaged. Electrostatic breakdown of the USB port.
- 💖Rich Expansion Functions: I2C interface is reserved. This port can also be used for material breakage, material blocking detection, or DIY operations for other functions. The factory is equipped with terminals, female reeds, double-way studs and screws for Meet the DIY needs of customers
- 💖Quality Commitment: Q: When updating firmware, it may be a risk that the heater sticks keep heating up A: please pay attention to disconnect the main power VIN of the hotend when using the DFU of Type-C port to update the firmware, or ensure that the firmware update is completed soon and goto the normal working mode. Never keep MCU in DFU mode for a long time when the main power supply and hotend are connected.If you still have any questions, you can ask us to send instructions

*by C***W on 30 October 2024*

For my Zero G Mercury One CoreXY build it was my ambition to run CANBUS to my print head, primarily to avoid having to install a thick umbilical to provide the discrete sensor and control data. This solution by BigTreeTech pairs nicely with my Manta M8P mainboard which already has CANBUS IO. In addition, I selected the EBB36 version as I was running a pancake Nema 14 stepper motor. The difficulties I had included flashing the right Klipper firmware to both boards, and then the power-up sequence to get them to recognize one another on the CANBUS and "shake hands". KB3D Wiki is a great resource in getting this working. Ultimately, it took several attempts before I got a stable and consistent connection between the two boards, but it now works. Many argue that the accelerometer data generated by input shaping needs high bandwidth to calculate a good result, but I have noticed that running your CANBUS on 500k bus speed is sufficient for all your needs. I would also caution you to provide proper strain relief for the umbilical so that you don't pull the connector from the solder pads on the board. Still highly recommended! But setup is not for the faint of heart!
