Machine Design


The entire project is hosted on the FabLab Napoli website, where I realized the project in collaboration with Enrico Cacciapuoti

Assignment:


Automate your machine document the group project and your individual contribution
For this Assignment the first thing i do is to undersand how I can control the stepper motor, using a Gcode. I search some tutorials on internet, that can help me to understan how stepper motor works, and how I can configure the electric connection for automate the machine. I follow this tutorial:

Tutorial
First create a circuit on a bradboard and one A4988 Diver, and I understand how I must do the electronic connections, on the CNC shield we want to use. The test i do is this:


One of the problems is with the regolation of the the potentiometer on the Driver, It's important because It need to set the how current must flow on the Stepper and have a good performance of it. This is the image of the X axis with the Stepper Driver and the complete electronic connections: This the Electronic Hardware I use and the connections for the stepper: After Enrico Upload, the gbrl firmware on the CNC shield, I try to understan how works chilipeppr gcode sender

Mechanical Design

Assignment


Design a machine (mechanism+automation), including the end effector build the passive parts and operate it manually document the group project and your individual contribution
Work
For this Assignment I and Enrico desided to build a camera slider for his camera, but we think it is possible to use with other device, like Xbox Kineckt and other. The first step is dividing task. I choose to design the slide where the camera moves. I found different previous students that build this kind of slider. Like this or
This Before start to Design the slide I need to kwow wich components I need. Component we need for the Slider: 1 Pulley for the Stepper Motor: model Gt2 for belt 6mm 28 teeth more informations Here
1 Belt to cut, width:6mm
3 Stepper Motor Nema 17
1 Pulley withouth teeth for the tensioner
2 Aluminum bars without thread
3 Driver A4988Here a screenshot of the BOM:

Slider
I print the part I designed with a Zortra M200, I set this parameters on Z Suite:
  • Layer = 0.09
  • Infill = Max
  • Quality = Max
  • Support = Yes Angle = 20° Option = Support Lite
  • Fan Speed = Auto

Here the image of the printed part:
This is the video where can see the manually movement of the X axis:
