Group Project
For this week we work in groups to design a machine and make it work. We decided to make a CNC drawing machine we called Maggy. The group web site is here.
We use the James Coleman and Nadya Peek project as a tutorial to construct our 2 axis drawing CNC, our goal is make it draw something.
Individual Contribution
Machine research
First, we start by reviewing [m] MTM
Modular Machines that Make: CNC Cardboard By James Coleman, Nadya Peek
A framework for the rapid prototyping of rapid prototyping machines. Modular hardware, modular electronics, and modular software. It is an excellent resource because it is very well illustrated and you can download the files of cardboard cut. It is also an example execel as a documentation guide for Fab Academy. The Modular Machines that Make project is a collaborative project born out of the 'Machines that Make Project' inside the Center for Bits and Atoms at The Massachusetts Institute of Technology. Current research also sponsored by the MIT - SUTD Collaboration and International Design Center. Check more information here
The other very interesting source in this research project is the same authors. How to Make (Almost) Anything Machine building week 2014 By James Coleman, Nadya Peek
How to Make Something that Makes (almost) Anything An introduction to machine building is given during one week of HTM(A)A, towards the end of the course when students have amassed many of the skills necessary for machine design.
This is a real challenge, but it leaves many experiences, working as a team for a week to design and look for a machine, made of cardboard. Check more information here
Another interesting resource for the group project I found in Instructables there were two projects: High Precision Cardboard CNC Drawing Machine by Dan Chen in cnc and How to Make Arduino Based Mini CNC Plotter Using DVD Drive by CNC World in Arduino
