This all-in-one 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. Please note that this particular RAMBo configuration does not include any wires or connectors.
Need Wires and Connectors?
The RAMBo v1.3 Kit comes with wires and connectors!
RAMBo v1.3 is built on the shoulders of the Arduino community, so hackers should consider 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.

Out of the box, a LulzBot 3D Printer comes tuned to perform exactly as you need it to. But over time we flash new firmwares, take our printers cross country, swap tool heads, perform cold pulls and a whole swathe of other things that could slowly tak...
- Support Material: Printing and Removal
By default, FFF/FDM 3D Printers require the 3D Models they print to grow up from the Print bed at an angle of 45 or more. This is by far the biggest limitation of all 3D Printers. To print models that don't follow that rule, and have parts hanging ou...
- Designing FDM 3D Printed Parts for Manufacture
Recently, we've talked a lot about Slicing software, settings, materials and the like. It's time to take a deeper dive into the actual design of model files. We've got a basics guide for Computer Aided Design available here. We're going to help expla...
- OctoPrint Integration with Cura 2.6+ Lulzbot Edition
OctoPrint Integration is one of my favourite new features in Cura 2.6+: LulzBot Edition. In short, this integration means that you can print and control your 3D Printer via it's OctoPrint server. All from within your slicer window on your PC. The cur...
- Cura 2: Lulzbot Edition for Intermediate Users
After some serious touch time your LulzBot 3D Printer and the quick print options in Cura 2, it's more than likely that you want to make more specific changes to the way 3D Models are printed. Whether it be, changing the support type and style to mak...
- Concrete Lamp
Welcome to my project on how to make a very stylish lamp out of a potentially un-stylish material - concrete! To be honest, style (or rather beauty) is in the eye of the beholder and so I'll leave it up to you to decide if it fits in your surroundings or not. What do you think? All the necessary steps are here but if you don't like reading the just sit back, relax and watch the video instead. When I said to people at work that I...
- Time lapsing in OctoPrint (Properly!)
Now that we have decked out our Lulzbot Taz 6 3D Printer with a really nice looking acrylic enclosure, I'm just about ready to turn on some serious 3D printing work. But before I dive into that endless pool of fun, it's a good time to take 5 minutes and set up our Taz 6 and it's OctoPrint Server with a bed-mounted camera and light system. That way I can monitor my prints from the other side of the warehouse using OctoPrint, and m...
- Meet 'Holman' the Ultimate Bluetooth Speaker
Who says you can't have it all? Good looks and a great sound! My name is 'Holman" and I'm a Bluetooth speaker in the form of mans best friend - a dog of course! Why is my name Holman? Well, that's the name of the manufacturer of the PVC pipe I used and the name grew on me as I completed the project! Whilst this might look like a complex project if you have access to the metric PVC pipe and a 3D printer I'm actually quite easy t...
- The Hipster Coaster
We wanted to make a interactive display of the fun that can be had with DIY projects to take to Sydney Mini Maker Faire. We decided to do so by utilising the TinkerKit Braccio from Arduino.org, alongside some 3D Printing ingenuity, for an engaging display for all ages. Enter the Hipster Coaster in all its glory. All the parts were printed seperately on our family of Lulzbot 3D Printers, later stuck together using a mi...
