"THE MUSIC PICKER"

A MUSICBOX SHEET CUTTER MACHINE For Music Box Lovers

MY ROL

 During this next 2 weeks my rol will be focuss on:

a) Documentation Project

b) Electronics

c) CodeMaker (Website & Machine)

d) Maker

Our Machines Design References

Documentation : Designing the Website

PrePoduction Files, Embedded Wrappers Settings Machines, Embedded for Designs, Embedded video and pics files postproduction...etc.

YOU CAN VISIT IT HERE :

MTM : THE MUSIC PICKER MACHINE WEBSITE

1. First I did was choose a minimal Webtemplate and passed it to my classmates for to decide if we like. They decided quick so we got it.

2. Later i propose them talk about our License and propose them a CC with non Commer-cial Attribution Share Alike. I made this too.

3. I began with Website coding, selecting important section and making notes on my notebook about formats things.

Here is the Music Picker Site :

4. Made Scheleton Document File at Google drive to share with our instructor :

  • Index : With more than 30 pages about the our processes followed and others that we must to follow..
  • Contents : Reuniting Texts, Making Settings Tables about Technological Processes, Manage hero pics and Vídeos.
  • Machine overview : For extract things to our website and Final Slide Document.
  • BOM : Wrappers about Materials, components with estimated cost because we recycled some things mechanisms from other machines.

    5. I also made a SketchFab Collection Parts for have details views abut the Music Picker Designs Parts.

    You can see and download all parts design here :

    LEARNING ABOUT ELECTRONICS FOR MTM

    I was doing all Electronics for the Machine. For began with this i studied all tutorials about FabNet, the RS 485, the Gestalt Nodes and wich Power Supply will to need our machine calculating the power consumption about the steppers motors, the drivers...

    Readed Tutorials :

    1. Our FabNet board : We used the Bass Design present at 2016 Tutorial :

    MILLING THE FABNET

    WHAT IT DOES

    Fabnet is a multi-drop network, meaning that multiple modules (a.k.a. nodes) share a single set of communication wires. Signalling is differential based on the RS-485 specification. Each node is assigned a four-byte IP address which uniquely identifies it over the network. Besides communication, Fabnet provides power at two voltages: high voltage (12V - 24V) is intended to drive motors, lamps and actuators, while low voltage (7.5V) supplies power to the logic circuits of the nodes.

    WHAT YOU NEED Establishing connectivity between nodes and a computer, and providing proper power, requires several components: high and low voltage power supplies, a USB-RS485 converter cable, and an adaptor board (076-000A) with bias resistors.

    OUR MACHINE have 3 Gestalt Nodes for control 3 AQS Nema 17 and for prepare all the stuff we made a BOM downloable here :

    POWER SUPLY:

    Our motors need 700 mAh minimun for works and the Gestalt Nodes as our instructor said us no to much so we decided to use an 12V- W Power supply for our Design.

    2. The RS 485 : The FTDI cable provided is a little different than the other FTDI cables we've been using; it is an RS-485 version. Here's its pinout for reference:

    3. The Gestalt Nodes :

    3. Motors :

    Maker Time

    As i documented the process i participated in all design process but focus in things like prototyping and building and my rols was : Fabricating Parts Pieces for prototyping with differents technologies such as Laser Cutter Machine and 3D Printers :

    I also designed with Fusion 360º some Supports Pieces Parts.

    MAIN BASE At CNC Router Machine Cutting main Design Part :

    WEEK PROBLEMS

    I burned a Node by bad wiring connections to the power Supply, but thanks to all we just will use 3 nodes for our machine.

    Also have a bit problem listing my RS 485 Serial port connection but o solved quickly.

    WEEK´s LEARNED

    A lot about mechanisms. New Words for my glosary about design processes. The references about electronics and useful design about the fabnet. The electronics and components used as common for every mtm. All about MTM Design and Automate Machines.

    Read deepthly the Nadia´s Thesis open my mine for a lot possibilities.

    WEEK CONCLUSIONS

    Essential week for learn about to design and fabricate a machine with different axis.
