Hey Jasmine, There’s plenty of affordable instruction material out there to choose from. It all depends on your familiarity or basic understanding of CNC machines. I listed some online references you can look into below for your review. If you’re interested in this information as a career change or job opportunity then I would suggest you look into an apprentice opportunity. You can find out everything you need to know about apprenticeship on the US Dept of Labor website (http://www.dol.gov/apprenticeship/). Hope this infom is enough to get you started. Good Luck!
