Brainstorming as a group

In Seoul, non of us have experience in machine building or programming. We decided that we want small CNC for cutting PCBs.

Useful links:
- [m]MTM by James Coleman, Nadya Peek
- How to Make (Almost) Anything: Machine Building.
- Jonathan Ward's MTM
- James Coleman 5 Axis Timiing Belt MTM.

At the end, we referenced Fablab Seoul MTM.

Designing Prototypes

At the beginning, I had NO CLUE AT ALL! However, one thing that's great about having team with same level of understanding is that there are no stupid questions and we were there to start together.

We had hard time dividing team work. We are all new to mechanical design, so we decided to make one prototypes each and evaluate our outcome and make a better version as a team. As a result, Hyejin and I designed and laser cut a model, tex did software and Rodrigo made joinerys. We had three meetings of brainstorming and attempt to understand CNC.

I tried to work with Fusion 360, but killed too much time just to understand the software. I went back to Rhino.

I made a CNC machine that is just for one purpose.

Measurements:
Aluminum shafts diameter: 9.5mm
Stepper Motor size: 43mmx 43mm
Leadscrew diameter: 7.85mm
Cardboard thickness: 8mm

My first cardboard CNC!

Here is HyeJin's prototype

It worked nicely as cardboard prototype, but I had errors. Also, we moved on to the ideas of making it moduler. After analyzing Fablab Seoul MTMs. We added improvements.
