I have been in the RC hobby for a while now and cutting foamboard and wood has become quite boring and annoying. I need help to find what part list would best fit what I need the machine to do, and I'm hoping the experts over here can help me. I have experience building 3D printers so I know the very basics. I was hoping I could make a machine that can cut a full size foam board (20"x30") and can also cut wood, I want to be able to keep the cost at around $400. All help would be greatly appreciated!
