12. Machine Design

Objectives

Group assignment

  • Design a machine that includes mechanism+actuation+automation+application
  • Build the mechanical parts and operate it manually
  • Document the group project and your individual contribution

The Twelveth week’s class of my fab academy life took place and the professor Neil class started as usual,this week assignmend as khown as Output Devices

Different major work assigned is given below.

  • 3D designing - Jowshin Emmanuel Johnson

  • Fabrication and testing - Arun Bobby

  • Electronics - Minshad Babu

  • Documentation and milestone keeping - Muhammed Fahiz KP

Electronics So Electronics is my work for the machinw design week

So I start my works

We used the Marlin board for electronics.

Our decision is minimalism in our machine. So we added Our board on X gantry.

Benefits

Only 2 cables (data and power cable) are moving outside the machine.

Some more mistakes we made

  • We forgot to add dogbone in some joints of press fit. So we would sand that portion.
  • We hadn’t added a hole for belt for Y-axis, Then we drilled on X-gantry for belt.
  • We didn’t discuss about wiring in design. So we would add some holes for add wires.
  • We didn’t add hole for the screwing board on the machine. So we used a double tap for sticking the Board.
  • We designed as 3mm hole diameter, but we didn’t have a 3mm bit for ZUND. So we would change the design file. Programming.

We used Ramps board with Marlyn firmware and cnc js as the controller software for running the Nishchal

We used the machine for product video shooting by manually jogging the axes in a desired path.

Tasks

  • Connect 2 NEMA 17

  • Convert 28BYJ stepper motors into bipolar stepper motor Our plan is:

  • Create GCODE for camera movement with Fusion 360 or other software.

  • Run the code with the help of a firmware. Components Required

  • Arduino MEGA x1

  • Ramps 1.4 Shield
  • A4988 Stepper Drivers x4
  • 28BYJ stepper motor x2
  • NEMA17 Stepper Motor x6
  • 12v 5A Power Supply We collected above components from the lab and tested by running a basic stepper arduino code.

We converted

Working video

What I learned

  • I learned how to plan an idea for making.

  • I learned how to design for making something.

  • I learned how to complete a work in time.

  • I learned how to troubleshoot problems during making of a machine.
