17. Machine design¶
Group assignment: Actuate and automate your machine. Document the group project
Individual assignment: Document your individual contribution.
Mechanism of Cardboard CNC (Reynaldo Bruno Baldini Garcia)¶
This is the assembled 3D model of the Cardboard CNC that includes only the mechanical parts.
Here you can see the machine full assembled.
These are the belt attachment system,that used the shape of the belt to hold it.
Instead of using linear bearings we used 3d printed bushing. With a bit of lubricant moves perfectly.
Electronics of Cardboard CNC¶
Fabduino Tecsup 2019¶
This is the 3D model of the Fabduino that was made with Autodesk Eagle with Autodesk Fusion 360 synchronization.

GRBL Shield for Fabduino Tecsup 2019¶
This is the 3D model of the FabDuino GRBL Shield that was made with Autodesk Eagle with Autodesk Fusion 360 synchronization.
Here you can see the stepper motors that we used.
In this case we see the stepper motor drivers used, that are connected on the FabDuino GRBL Shield.
This is the FabDuino connected on the FabDuino GRBL Shield. We can see as well that the FabDuino is painted using synthetic aerosol paint, in order to protect the copper layer.
This is the FTDI cable that is used for communication with the softare called Universal gcode sender for testing and calibration. Once is calibrated we used our own softare.
For connecting to the supply voltage the FabDuino we used this connector called Jack 2.5 mm.

Software of Cardboard CNC (Diego Santa Cruz Meoño)¶
A demo of the machine running¶
This is the Demo Video of the machine working.
The machine was tested using the Software called Universal Gcode Sender and a GUI written in Python and Tkinter.
