BIGTREETECH MMB CAN V1.0 Board for Voron ERCF System, Control Board for Enraged Rabbit Carrot Feeder Support Multi-Material Feeding, for Voron 2.4 and Klipper 3D Printers DIY

The Bboard seems to be well-made, but I have not been able to get it working with my ERCF. I suspect the issue lies in software configuration, but the GitHub documentation isn't very helpful, and I'm struggling with it.BTT is a major supplier of controller boards for 3D printers, so I wish they would improve the quality and quantity of their documentation. It would make troubleshooting and setup much easier for users.

This is the latest control MCU for the Voron ERCF Multi Material Feeder. The board is supported by Klipper and features CAN and USB-C connectivity. The added sensor input and LED support makes this Board superior to any that have come before especially if integrating with Happy Hare software. It is directly configured by the Happy Hare software installation program.

I have now received two of these boards. Both were defective with different problems. My original BTT MMB CAN that I have been using for months works fine on either ERCF, confirming the problem is with these boards. The fact that both boards had been opened, returned, and then resold as new might explain it.

This board is a works well for ERCF. It connects easily via CAN and USB-C. Be aware the documentation could be better, but once configured, it integrated seamlessly with klipper!
