Explained your individual contribution to this project on your own website (individual assignment)

My main contribution in the development of the machine was that of electronic production and programming. Below I describe the steps for assembly of circuit control:

For the circuit I used A4988 that is a bipolar stepper driver circuit that allows you to drive a bipolar stepping motor up to 2A of current from any microcontroller. This driver for stepper motors has a current limiter, and protection from overheating and over consumption to ensure proper operation when you use it in your projects. The driver operates in a range of 8 to 35V with a current of 1A per phase (without a heat sink) and has the capacity to support up to 2A per coil if there is sufficient additional cooling.

Datasheet

Design in Eagle Software

Manufacturing and assembly

Programming

The programming used was GRBL , which we loaded from the Arduino IDE

Grbl is a free, open source, high performance software for controlling the motion of machines that move, that make things, or that make things move, and will run on a straight Arduino. If the maker movement was an industry, Grbl would be the industry standard.

Control with graphic interface

For upload the G-CODE we used UGSPLATAFORM

The UGS Platform is the next generation of Universal Gcode Sender. It is built ontop of the Netbeans Platform which allows us to leverage its mature modular framework. This platform allows more features to be added without compromising on code quality, or being bogged down by a home grown framework. The Classic GUI is used as a library, so core features benefit both interfaces
