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

BTT has bad quality control and CAN transceivers are known to blow up even from well respected companies, so this isn't a great combination. But this is a cost effective solution and works most of the time. Thankfully, I didn't get a lemon with my U2C. It was extremely easy to use and setup. This is pretty much plug and play. You put it into boot mode, you update the firmware from github, and then you have a working CAN connection to your toolhead.

Printed a DIN bracket, mounted it, wired it and worked without any issues.

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.

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.

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.

I'm using this on my latest printer build to keep the hotend wire count low. Works great now. I'm not sure if I had an old batch, but the original firmware was sending packets out of order and causing errors in klipper. I flashed the latest firmware from their GitHub page and the errors went away. Been great ever since!

I'm a very experienced Linux user, and tried everything to get this to work. From the official V2.1 (upgraded) firmware from BTT to re-compiling candlelight_fw and such, to using Katapult and klipper, and no options ever got me to be able to talk to my toolhead board (EBB 2209 2040). This is despite the adapter seeming to be registered as can0 on my rpi ok. After almost two weeks of screwing around with this on and off, I decided to get another CAN adapter (FYSTEC UCAN). It's cheaper even! and it just worked. No issues.
