DIYlilcnc.org For roughly $750 in parts, + laser cut panels (which usually run $250 dollars for someone to cut them for you on a lasercnc) you will fully understand how a cnc machine works, how steppers work and programming software. There is a full 60+ page pdf on how to build the machine, a open forum, etc. Both the creators are educators and wrote the PDF amazingly. PLUS the plans are 100% free along with the forums. That is how i got my feet wet. If you have a $1000 dollars it will be money well spent, not just on a machine but education that will put you on the next level along with your business. It will open doors for you to build a much larger cnc and fully understand what is going on with the parts, electronics etc. Just my 2 cents.
