    3D Printer Can Bus Toolhead

    In an attempt to further minimize points of failure on my printers I decided to install a EBB42 CAN Bus PCB board. This will allow me to reduce the wire count at the tool head from 14 to 4 wires.

    Wiring Harness

    • Wire Harness will be terminated with a 4 pin NLINKO connector
      • This is the same connector that hart1213 utilized for his umbilical

      • If the NLINKO Connectors prove to not be good I will swap this to M12 Connectors
