Hi OmriBig,
I know this post is old, but I just stumbled on it and hope you can answer a few questions. The drawings are extremely cool.
What software did you use?
Did you have any feedback mechanism? For example, did you use a camera to look at the drawing as it progressed and add more lines where they were needed? Or were the movements pre-determined?
How long does it take to draw?
How is the MPCNC design working for you? I have a friend that is interested in building one.
thanks
Steve
