- BIGTREETECH EBB42 CAN Bus with MAX31865 Adapter Board Hot End PCB Board Filament Break Blockage Detection for 42 Stepper Motor Extruder Nozzle Head Tool for Blv Ender 3 for Klipper Support PT1000

Great little board. Used on a Sovol sv08 to convert to Can communication. Connectors used on this board are 2.5 pitch which makes a whole lot of difference with ease when comparing to the 1.5 pitch on the Sovol stock board. Easier to crimp in case you pull out a wire when disconnecting a connector and way easier to crimp. Simple installation when following the manual on the btt GitHub page. Though, having some experience connecting to your printer host via ssh and using the Linux command line helps. The heater terminals are also larger than the ebb36 board which also makes it easier to install the heater wires and using ferrule connectors. Using the board to connect an eddy dual, x endstop, filament sensor, extruder fan, two part cooling fans spit into one connection, neopixel leds, heater, and thermistor. Still have a few pins to use if something comes to mind. Good buy.

Removed artifact in on my prints and made my machine run quieter. Now it’s the fans I hear instead of the frame humming. Was easy to configure and setup.

Item arrived on time in excellent condition.

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!

This is the 3rd one I have purchased and they all work. I use USB connection instead of can communication. GitHub repository has been reworked and is a lot easier to read and understand than it used to be. Good luck.

I had to redo the wiring on my Ender 3 after making some major upgrades - moved to direct drive from a remote feed system, including an Orbiter - and had some REALLY long wire runs back to my control boards. I run Klipper so the option of using only four wires to bring all my hot end controls back to my Raspberry Pi sounded great. I mounted this on a point behind my print head as the board will not fit on the back of the NEMA14 motor like it would on a NEMA17. It did take a bit of programming work to get the CANBus set up in my printer config but now it is controlling the following: two fans, extruder motor, extruder heater, BLTouch, hotend LED and filament runout sensor.

I have been through so many of these boards, either from them failing in incredibly short order or showing up DOA. Its incredibly frustrating to try and print something, only to get random failures for no reason. Losses in connection with the MCU, random overload issues, loss in heating, fan MOSFETs burning out, you name it and it'll happen. I think my record for keeping one of these alive is something like 4 months, that is absolutely unacceptable

I tried using a standard accelerometer to run input shaper but ran into a lot of issues getting it to work with my RPI. Using the USB interface and the onboard MCU made this SOOOOO much easier. 10 out of 10 recommend this product for anyone looking to run input shaper. The manual method is completely useless IMO.
