CNC to Art Video Series Video 10: This is the CNC Video series on how to take an image to a CNC File. This process is one that many CNC Users want to know, but there is not much info on. Here is your chance to get the inside scoop. For more information, please go to: www.cncinformation.com Before we head out to the shop and begin CNC Plasma Cutting, we will check out our G-Code program in Mach 3. This will give us some confidence when running our CNC Program. Mach 3 is a great CNC Control Program. It takes our G-Code and converts it into Signal for the CNC Controller. The CNC Controller then sends the signals out to either Servo Motors or Stepper Motors. These motors then move the axis to create motion.
