Assembled RAMBo v1.4 Kit with LCD Harnesses

This all-in-one TAZ 6 3D printer motherboard is made by UltiMachine using an Arduino MEGA microcontroller board, and comes equipped with integrated stepper drivers, built in fuses, and more. The RAMBo 1.4 board is the direct replacement for the RAMBo used in the LulzBot TAZ 6 and includes the two wiring harnesses used to connect to the Graphical LCD Controller.

Product Alert (3)
  • Note:

    Please contact us for help before purchasing this component if you own a LulzBot TAZ 6 and would like assistance within the standard warranty period.

  • Compatibility: 

    RAMBo v1.4 is only compatible with the LulzBot TAZ 6 3D Printer. LulzBot TAZ 5 and earlier 3D printers are only compatible with RAMBo v1.3.

  • Product Alert:

    A new Graphical LCD Controller Cable is included due to the differences between the connectors on the RAMBo v1.3 and earlier and the RAMBo v1.4.

  • Features

    Since RAMBo v1.4 is built on the shoulders of the Arduino community, makers and hackers should consider using this motherboard for additional projects beyond controlling a 3D printer.

    Curious where the product's name comes from? This motherboard is a full remix of UltiMachine's popular RAMPS design, with the Arduino MEGA and stepper drivers all on one integrated PCB. Thus, the name (R)epRap (A)rduino-MEGA-compatible (M)other (Bo)ard (RAMBo) was born.
