Project

What will it do?

It is a machine that allows you to extrude PLA plastic under the same conditions as a common fdm 3d printer but manually.Using the most common components of the home 3D printers such as the NEMA 17 stepper motor and the E3D v6 hotend

Who's done what beforehand?

There are many business models.

I could not find an open source version although in reality all the printers with bowden use this same system of filament extrusion but integrated in a more complete system of axes

What parts and systems will be made?

1.- PCB
2.- 3D diseng
3.- Digital Fabrication
4.- Programing

What processes will be used?

1. Electronics: INPUTS + OUTPUTS
2. 3D PRINTING
3. LASER CUTTNG
4. PROGRAMMING

What tasks need to be completed?

Indibidual programs for, thermistor, mosfet, motor and serial communication using arduino leonardo.
Coordinate thermistor and heater with PID (Arduino Phthon)
Transform 12v to 5v to feed Raspberry Pi
Manufacture a PCB that also integrates the motor driver and a 5v output for the fan.
Design some way to hold the handle and draw well.
Integrate all processes into a finished product

What is the schedule?

I have less than three weeks for accomplish all three areas. I will work on them in parallel, trying to develop step by step a little bit of everything rather than focusing in the three areas separately. I will focus on spiral development and document while I'm working.
I have many things to do in the field of electronics that is my greatest concern, it is possible that some objectives are simplified in the end

How will it be evaluated?

Must function mechanically and the program
