BIGTREETECH U2C V2.1 Adapter Board Supports CAN Bus Connection with 3 CAN Output Interface to Raspberry-Pi Printer 3D Parts

Bit of a pain to setup and re-crimp with the included pins and connectors but I get it, there is limited room inside that toolhead (stealthburner). as far as functionality goes, this board works fantastic and have not had any issues. Went through the Esoterical CANbus guide to setup a direct CAN host to my BTT Octopus - https://canbus.esoterical.online/ and it worked great just follow the directions very closely. Make sure to cut and crimp your toolhead fan and LED wires to exactly the size needed as there in no room in there for extra wires. Great Job BTT, nice board.

I have had no issues in the months that I've swapped to CANBUS on my V2.4. I've printed maybe 100 hours since upgrading and everything has been running flawlessly.

Though it sounds great to be able to swap out hotend types, sensor types without dismantling the bunch of cable tracks, it does take a great deal of configuring, and can be confusing if you don't understand how it all talks.Bigtreetech has a great manual which you should read first before tearing into this to know it will be an undertaking. Once you follow their great instructions it will be rewarding as it will be easy to manage upgrades in the future.It is a great kit, well documented, frustrating and fun

I don't know if I got a lemon but after getting this set up, the TMC2209 has overheated my LDO extruder motor consistently. Turning stealthchop off helped very minimally but the driver doesn't respect the run_current. Still overheats the motor with the current set to 0.1. Very unhappy with this board. Never had this issue using the 2209 on my octopus board so it's gotta be this can board that's the issue

I added TAP, and a Canbus board to my Voron 2.4. The default Octopus 1.1 board I have read that the Canbus on the controller is not as stable as you could hope. This board paired with the EBB2240 board is a perfect match. I am running a pair of them and once I configured it I have had no issues after I made sure that the fan board did not short to the mylar sticker on the fan in the Stealthburner tool head. For set up instructions. Google Esoterical Canbus Guide for the best instructions on how to do this without driving your self crazy. The jump to can bus is the best upgrade I have made. No more surprise broken wires in the cable chains.

I recently installed the CAN Bus to USB board on my modified Ender 5, and I must say, it's been a game-changer for my 3D printing experience. The board allowed me to establish a seamless connection between my printer and computer, enabling smoother data transfer and control.One of the standout features of this product is its compatibility with my modified Ender 5 setup. The installation process was straightforward, and I encountered no compatibility issues. Within minutes, I had the board up and running, and I could immediately notice the difference in communication speed and stability.The board's build quality is impressive, providing a durable and robust connection that hasn't failed me since I started using it. Its compact design doesn't take up much space in my workspace, which is a big plus.Moreover, the CAN Bus to USB board has significantly improved my printing accuracy and reduced the chances of communication errors, leading to better print outcomes. The reliable connection ensures that I can pause and resume prints without any disruptions, which is a boon for larger and more complex projects.Although the board delivers on its promises, I feel there is room for some minor improvements. The documentation provided with the product could be more comprehensive, especially for those who are new to working with CAN Bus connections. Additionally, it would be helpful if the manufacturer offered better customer support to address any potential troubleshooting queries.In conclusion, the CAN Bus to USB board has certainly enhanced my 3D printing experience with the modified Ender 5. Its seamless connectivity, sturdy build, and improved printing accuracy make it a worthwhile upgrade for any 3D printing enthusiast. With a few minor enhancements to documentation and customer support, this product would undoubtedly earn a full 5-star rating. For now, I'm giving it a solid 4 stars and would recommend it to others looking to elevate their printing capabilities.

Does what is advertised. I will come back if it breaks in a few months. As of now we are 2-3 months in and no issues.

These are the pi based version. And it has the 2.0 mm JST connections. So you can actually crimp your own cables.
