The HipsterBot has an H-type belt configuration for controlling the X and Y axes. What’s special about this is that there are two stepper motors connected together with one long belt. If the steppers move in opposite direction, they control the X-axis. If they move in the same direction, they control the Y-axis. Therefore, the need for a linear mapping from a cartesian coordinate system into an H-belt coordinate system arises. In the RepRap community, the X-axis is usually the axis where the extruder sits, note that this is not the case here.
The advantage to this setup is that (with a Bowden extruder) there are no moving stepper motors to add weight to the carriage, so the speed can be high. The disadvantage is that there is some elasticity in the belt.
Luckily there’s a paper for that! …
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!Related
