A CNC mill like the dear Geil-O-Mat has three axis that can be moved independently. A spindle with a [http://de.wikipedia.org/wiki/Fr%C3%A4swerkzeug mill cutter] typically removes material. | A CNC mill like the dear Geil-O-Mat has three axis that can be moved independently.

Each axis is driven by one (Y and Z) or two (X) stepper motors. Basically, theses motors can only rotate in 1.8 degree steps, and hence no secondary encoder is needed for the machine knowing its current location. By a trick called "microstepping", currently the resolution is increased to 1/8 of 1.8 degrees. | Each axis is driven by one (Y and Z) or two (X) stepper motors.
