The RAMBo 1.4 board is an all in one 3D printer motherboard. It is a full remix of our RAMPS design with the Arduino MEGA and stepper drivers all on one integrated PCB.

That is where it got the name RAMBo - (R)epRap (A)rduino-(M)ega-compatible (M)other (Bo)ard.

RAMBo is designed to work with the current RAMPS generation firmwares with minimal modifications to add firmware control of the digital trimpots and the microstep setting pins.

This product is RAMBo pre-assembled where you will receive all electronic components securely soldered to the PCB, ready for use. You will receive the endstop wires & switches of your choice, wires are complete with pre-crimped & housed ends.  Also included are the matching pluggable terminal blocks, two thermistor wires with pre-crimped & housed ends, a USB cable & we throw in gold connectors/headers for use on the motors & possible extra fan.

Product features:

  • 5 x integrated 1/16th microstep motor drivers
  • 5 PWM Mosfet outputs
  • 4 thermistor inputs, digital trimpot (no tiny knobs to tweak)
  • SMPS supports hostless printing on power supply voltages from 10-24V DC
  • 3 independent fuse protected power rails
  • LUFA USB
  • high quality connectors

Firmware / Hardware Information:


Recommended Power supply 12V-24V DC, 16A+.

A preconfigured Marlin Firmware is preloaded onto the board. To re-flash this board, you can simply use the Arduino IDE and set board to "Arduino Mega 2560". There is also a Arduino plugin folder on github that exposes additional pins in the Arduino IDE.

Linux and Mac use CDC interface and have hardware driver built in.

Would this work on a cnc machine, home build? Three axis with drivers. What kind of software do you download to it?

I replaced the board on my TAZ 6 less than a year ago (equating to not that many print hours) because of the Y-axis motor malfunctioning. I had eliminated the motor as the source of the problem beforehand, and the replacement solved the problem. Now again, I have the same problem. The motor is getting some kind of signal, but the shaft doesn't rotate. I have tried with two different motors with the belt off with the same result. I guess I need another board replacement. My question is: Is this some kind of inherent flaw in the board? I guess I don't really have a choice if I want to keep the printer running, but hate to throw good money after bad. Are you hearing the same from other customers?

I have an Airwolf 3D AXIOM that currently runs on a RAMBo v.1.3 but needs to be replaced. Do you foresee any potential problems with using this as the replacement (obviously I would need to load the correct firmware onto the new board)?
