I have absolutely no idea where to begin. I want a machine that can cut acrylics, G, carbon fiber and if possible mm thick sheets of aluminium.
What do I need to learn?
What stepping motor, router, power supply and table is good for this machine.
Where can I buy the parts?
My budget is about $ to $. Is this realistic?
